    SUMMARY**
    Class Action / Restitution
    The panel reversed the district court’s denial of class
    certification in an action brought by a putative class of
    internet advertisers under California’s Unfair Competition
    Law and Fair Advertising Law, alleging that Google, Inc.
    misled them; and remanded for further proceedings.
    The plaintiff alleged that Google misled advertisers by
    failing to disclose the placement of AdWorks ads on parked
    domains and error pages; and sought, on behalf of the
    putative class, restitution of moneys Google wrongfully
    obtained from the putative class.
    The panel held that the district court erred in denying
    class certification based on its finding that the putative class
    did not meet the predominance requirement under Fed. R.
    Civ. P. 23(b)(3). The panel held that the district court erred
    by conflating restitution calculation with the liability inquiry
    for Unfair Competition Law and Fair Advertising Law
    claims, and by failing to follow the rule in Yokoyama v.
    Midland National Life Insurance Co., 
    594 F.3d 1087
    , 1094
    (9th Cir. 2010) (holding that damages calculations alone
    cannot defeat class certification). The panel further held that
    the plaintiff’s proposed method for calculating restitution was
    not “arbitrary” under Comcast Corp. v. Behrend, 
    133 S. Ct. 1426
     (2013).

    OPINION
    PAEZ, Circuit Judge:
    Between 2004 and 2008, many online internet advertisers
    used Google, Inc.’s (“Google”) AdWords program, an
    auction-based program through which advertisers would bid
    for Google to place their advertisements on websites. Pulaski
    & Middleman, LLC and several other named plaintiffs
    (“Pulaski”)1 brought this putative class action under
    California’s Unfair Competition and Fair Advertising Laws,
    alleging that Google misled them as to the types of websites
    on which their advertisements could appear. The putative
    class initially sought injunctive and restitutionary relief.
    After Google changed certain features of the AdWords
    program, Pulaski, upon filing a Third Amended Consolidated
    Class Action Complaint, abandoned the claim for injunctive
    1
    Hereafter, “Pulaski” refers collectively to Pulaski & Middleman, LLC
    and the other named plaintiffs, JIT Packaging Inc., RK West, Inc., and
    Richard Oesterling.
    4           PULASKI & MIDDLEMAN V. GOOGLE
    relief. The only relief the putative class now seeks is the
    equitable remedy of restitution.
    Pulaski appeals the district court’s denial of class
    certification. The district court held that on the claim for
    restitution, common questions did not predominate over
    questions affecting individual class members. In denying
    certification, the court reasoned that it was not bound by our
    decision in Yokoyama v. Midland National Life Insurance
    Co., 
    594 F.3d 1087
    , 1094 (9th Cir. 2010). It then explained
    that determining which class members are entitled to
    restitution and what amount each class member should
    receive would require individual inquiries that “permeate the
    class claims.”
    Pulaski argues that the district court erred in failing to
    follow Yokoyama. As explained below, we agree. We
    therefore reverse the denial of class certification and remand
    for further proceedings.
    I. Background
    A.
    This case concerns Google’s AdWords program, an
    auction-based program through which Google served as an
    intermediary between website hosts and advertisers. Through
    AdWords, internet advertisers provided advertisements to
    Google and its third party website-owner partners. To
    participate, advertisers entered Google-defined variables into
    the AdWords interface on Google’s website, including the
    maximum price per ad they would be willing to pay and their
    overall budget. They also selected which Google-defined
    categories of websites they wanted to display the ad.
    PULASKI & MIDDLEMAN V. GOOGLE                          5
    Afterwards, using an auction-based algorithm, AdWords
    determined the online placement and price of the ad. Thus,
    during the class period, advertisers did not know in advance
    exactly where their ads would appear.
    Advertisers paid a particular price to Google each time an
    Internet user “clicked” on their displayed ad. The price of a
    particular click depended on several factors: the maximum
    bids of other AdWords customers for clicks based on the
    same search term, a “quality score” of the advertisement, and
    a “Smart Pricing” discount applied to the website where the
    ad had been placed. Google created and instituted Smart
    Pricing, an internally-calculated price adjustment, to adjust
    the advertiser’s bids to the same levels that a “rational
    advertiser” would bid if the rational advertiser had sufficient
    data about the performance of ads on each website. Smart
    Pricing is a ratio calculated by dividing the conversion rate2
    for the lower-quality website by the conversion rate for the
    same ad on google.com.
    There are several categories of websites in play. During
    the class period, an advertiser using AdWords could request
    that its ads appear on Search Feed sites, Content Network
    sites, or both. Search Feed sites display AdWords ads along
    with search results after a user searches for information using
    a particular search term. After entering a particular term, a
    user would be presented with both ordinary search results and
    ads related to the search term. Content Network websites, on
    the other hand, are full content sites, like nytimes.com, that
    2
    Using Google’s terminology, a “conversion” occurs when a “click”
    leads to a particular business result defined by the advertiser, like a
    purchase or a sign-up. A conversion rate is the “number of conversions
    divided by the number of ad clicks over a defined period of time.”
    6             PULASKI & MIDDLEMAN V. GOOGLE
    publish information independent of search results. Ads
    would appear on these sites if the ad’s keywords matched
    those of the website.
    There are other categories of sites that did not appear in
    the AdWords registration process: parked domains and error
    pages. Parked domain pages are undeveloped domains whose
    pages appear when users type generic terms into a web
    browser. These are pages of ads without content. Error
    pages appear when a person inputs an unregistered web
    address, or something other than a web address, into a web
    browser’s address bar. Typing this information into an
    address bar used to result in error messages, but during the
    class period inputting this information resulted in error pages
    that offered ads. Even though only Search Feed and Content
    Network websites were listed in the AdWords registration
    process, AdWords ads appeared on both parked domains and
    error pages.
    B.
    Pulaski alleges that Google misled advertisers, violating
    California’s Unfair Competition Law (“UCL”), Cal Bus. &
    Prof. Code § 17200 et seq.,3 and California’s Fair Advertising
    Law (“FAL”), § 17500 et seq., by failing to disclose the
    placement of AdWords ads on parked domains and error
    pages. The putative class consists of “[a]ll persons or entities
    located within the United States who, from July 11, 2004
    through March 31, 2008 . . . had an AdWords account with
    Google and were charged for clicks on advertisements
    appearing on parked domain and/or error page websites,”
    3

    Professions Code.
    PULASKI & MIDDLEMAN V. GOOGLE                         7
    with exclusions.4 Pulaski, on behalf of the putative class,
    seeks restitution of moneys Google wrongfully obtained from
    the putative class.
    Pulaski moved for class certification pursuant to Rule 23
    of the Federal Rules of Civil Procedure (“Rule 23”) for a
    Rule 23(b)(3) class. Pulaski proposed three different methods
    for calculating restitution, all of which were based on a “but
    for” or “out-of-pocket loss” calculation: the difference
    between what advertisers actually paid and what they would
    have paid had Google informed them that their ads were
    being placed on parked domains and error pages. The first
    approach is based on Google’s Smart Pricing formula as
    described above. The amount of restitution owed a class
    member would be the difference between the amount the
    advertiser actually paid and the amount paid reduced by the
    Smart Pricing discount ratio. The second method is the
    Content Pricing approach,5 which factors in the lower bidding
    that would have occurred had advertisers been allowed to bid
    separately on parked domains and error pages. Search Feed
    clicks were priced higher than Content Network clicks, which
    in turn were considered more desirable than parked domains
    and error pages. Accordingly, where the same ad appeared
    both in the Search Feed and on Content Network websites,
    those Content Network ad prices could serve as a
    conservative but-for price for Search Feed clicks on parked
    domains and error pages. The third method is the Full
    4
    Beginning in March 2008, the AdWords interface allowed advertisers
    to exclude parked domain and error pages from the set of websites on
    which their ads could appear.
    5
    This method focuses on clicks on parked domains and error pages in
    Google’s Search Feed, not on Content Network websites.
    8            PULASKI & MIDDLEMAN V. GOOGLE
    Refund approach, in which advertisers would receive full
    refunds for clicks on ads placed on parked domains and error
    pages. Because some methods may work better than others
    for certain subsets of class members, Pulaski presented these
    methods as possibly complementary.
    In ruling on the class certification motion, the district
    court initially found that the proposed class satisfied all of the
    criteria under Rule 23(a): numerosity, commonality,
    typicality, and adequate representation. The court next turned
    to the predominance inquiry under Rule 23(b)(3). On that
    issue, it found that, even assuming the plaintiff class could
    prevail on liability, common questions did not predominate
    on the issues of entitlement to restitution and amount of
    restitution due each class member.
    First, the court expressed concern that individual
    questions may arise in ascertaining entitlement to restitution.
    It observed that “the question of which advertisers among the
    hundreds of thousands of proposed class members are even
    entitled to restitution would require individual inquiries.” In
    particular, the court was concerned with how to
    “systematic[ally] . . . identify and exclude from Plaintiffs’
    proposed class the many advertisers who have no legal claim
    to restitution because they derived direct economic benefits
    from ads placed on parked domains and error pages.”
    Second, the court identified individual questions that
    would arise in determining the amount of restitution owed to
    the class and individual class members. The court explained
    that our decision in Yokoyama, which held that damages
    calculations alone cannot defeat class certification, did not
    control the outcome of this issue because Yokoyama cited to
    decisions that mentioned a “workable method for calculating
    PULASKI & MIDDLEMAN V. GOOGLE                      9
    monetary recovery.” Here, the court held that the plaintiffs
    had not proposed a method that was workable. The court
    explained that different costs for each advertiser, each ad, and
    each click, overlaid with an auction process, make it “more
    difficult to calculate what AdWords customers would have
    paid ‘but for’ the alleged misstatements or omissions.” It
    concluded that Pulaski’s proposed methods were insufficient
    to account for all of the intricacies involved, including
    benefits received from parked domain and error pages.
    Concluding that individual questions predominated on the
    issue of restitution, the court denied Pulaski’s motion for
    class certification without addressing whether class treatment
    was a superior method for resolving the dispute as required
    by Rule 23(b)(3). Thereafter, Pulaski filed a motion for
    reconsideration, which the district court denied.
    We granted permission to appeal the order denying class
    action certification as authorized by Rule 23(e). We have
    jurisdiction under 
    28 U.S.C. § 1292
    (e).
    II. Standard of Review
    A district court’s class certification ruling is reviewed for
    abuse of discretion. See Parra v. Bashas’, Inc., 
    536 F.3d 975
    ,
    977 (9th Cir. 2008). “A district court would necessarily
    abuse its discretion if it based its ruling on an erroneous view
    of the law or a clearly erroneous assessment of the evidence.”
    United States v. Hinkson, 
    585 F.3d 1247
    , 1259 (9th Cir. 2009)
    (en banc) (quoting Cooter & Gell v. Hartmarx Corp.,
    
    496 U.S. 384
    , 405 (1990)). “[W]hen an appellant raises the
    argument that the district court premised a class certification
    determination on an error of law, our first task is to evaluate
    whether such legal error occurred.” Yokoyama, 
    594 F.3d at
    10          PULASKI & MIDDLEMAN V. GOOGLE
    1091. “If the district court’s determination was premised on
    a legal error, we will find a per se abuse of discretion.” 
    Id.
    Otherwise, “we will proceed to review the district court’s
    class certification decision for abuse of discretion as we have
    always done.” 
    Id.
    III. Discussion
    To obtain certification, a putative class must satisfy four
    prerequisites:
    (1) the class is so numerous that joinder of all
    members is impracticable; (2) there are
    questions of law or fact common to the class;
    (3) the claims or defenses of the
    representative parties are typical of the claims
    or defenses of the class; and (4) the
    representative parties will fairly and
    adequately protect the interests of the class.
    Rule 23(a). Additionally, the proposed class must qualify as
    one of the types of class actions identified in Rule 23(b).
    Here, Pulaski sought to certify a class under Rule 23(b)(3).
    Under Rule 23(b)(3), the court must find that “questions of
    law or fact common to class members predominate over any
    questions affecting only individual members,” and that a class
    action is “superior to other available methods for fairly and
    efficiently adjudicating the controversy.”
    Pulaski must “affirmatively demonstrate . . . compliance
    with the Rule.” Wal-Mart Stores, Inc. v. Dukes, 
    131 S. Ct. 2541
    , 2551 (2011). The question of certification requires a
    “rigorous analysis.” 
    Id.
     Courts may have to “probe behind
    PULASKI & MIDDLEMAN V. GOOGLE                            11
    the pleadings before coming to rest on the certification
    question.” 
    Id.
    The district court denied certification because it found
    that the putative class did not meet the predominance
    requirement. It explained that questions regarding which
    advertisers are entitled to restitution in the first instance, and
    the amount of restitution owed to each advertiser, both defeat
    predominance. We disagree.
    A.
    Entitlement to restitution is a separate inquiry from the
    amount of restitution owed under California’s UCL and FAL.
    To the extent that the district court rested its holding that
    common questions do not predominate on the putative class’s
    entitlement to restitution, it committed legal error.
    The UCL prohibits “any unlawful, unfair, or fraudulent
    business act or practice.” § 17200. The FAL prohibits
    “untrue or misleading” statements in the course of business.
    § 17500. This language is “broad” and “sweeping” to
    “protect both consumers and competitors by promoting fair
    competition in commercial markets for goods and services.”
    Kwikset Corp. v. Super. Ct., 
    51 Cal. 4th 310
    , 320 (2011).
    To state a claim under the UCL or the FAL “based on
    false advertising or promotional practices, it is necessary only
    to show that members of the public are likely to be deceived.”
    In re Tobacco II Cases, 
    46 Cal. 4th 298
    , 312 (2009);6 see also
    6
    Since the passage of California’s Proposition 64 in 2004, private suits
    must also allege standing under the UCL and FAL, i.e., that the plaintiff
    “suffered injury in fact” and “lost money or property as a result of unfair
    12             PULASKI & MIDDLEMAN V. GOOGLE
    Stearns v. Ticketmaster Corp., 
    655 F.3d 1013
    , 1020 (9th Cir.
    2011) (holding that a district court erred in denying class
    certification by requiring individualized proof of reliance and
    causation, and remanding in light of In re Tobacco II Cases),
    cert. denied, 
    132 S. Ct. 1970
     (2012). This inquiry does not
    require “individualized proof of deception, reliance and
    injury.” In re Tobacco II Cases, 
    46 Cal. 4th at 320
    ; Stearns,
    
    655 F.3d at 1020
     (same). “[I]n effect, California has created
    what amounts to a conclusive presumption that when a
    defendant puts out tainted bait and a person sees it and bites,
    the defendant has caused an injury; restitution is the remedy.”
    Stearns, 
    655 F.3d at
    1021 n. 13.7
    competition.” Kwikset, 
    51 Cal. 4th at
    320–21 (noting that the proposition
    “curtailed the universe of those who may enforce” the UCL and FAL,
    although the laws’ “substantive reach . . . remains expansive”). There is
    a two-part test for standing under the UCL and FAL: the person must
    “(1) establish a loss or deprivation of money or property sufficient to
    qualify as an injury in fact, i.e., economic injury, and (2) show that that
    economic injury was the result of, i.e., caused by, the unfair business
    practice or false advertising that is the gravamen of the claim.” 
    Id. at 322
    .
    Here, the district court determined that one of the class representatives had
    standing to sue, and that the class representative’s standing satisfied the
    standing requirements for the putative class as a whole. Neither party
    challenges the district court’s ruling on statutory standing. We therefore
    do not address it.
    7
    Stearns, which was decided before the district court’s ruling here, also
    noted that predominance may not exist in a UCL case in which different
    members of the class were “exposed to quite disparate information from
    various representatives of the defendant.” 
    655 F.3d at 1020
    . We have
    elaborated on this concept in two cases that post-date the district court’s
    order. See Mazza v. Am. Honda Motor Co., Inc., 
    666 F.3d 581
    , 596 (9th
    Cir. 2012) (holding that common questions did not predominate where
    disparate information exposure undercut presumption of reliance); Berger
    v. Home Depot USA, Inc., 
    741 F.3d 1061
    , 1069 (9th Cir. 2014) (holding
    that predominance did not exist for a putative UCL class whose members
    had each been exposed to one of five different contracts, each of which
    PULASKI & MIDDLEMAN V. GOOGLE                          13
    Under the UCL:
    Any person who engages, has engaged, or
    proposes to engage in unfair competition may
    be enjoined in any court of competent
    jurisdiction. The court may make such orders
    or judgments, including the appointment of a
    receiver, as may be necessary to prevent the
    use or employment by any person of any
    practice which constitutes unfair competition,
    as defined in this chapter, or as may be
    necessary to restore to any person in interest
    any money or property, real or personal,
    which may have been acquired by means of
    such unfair competition.
    § 17203. This language, as well as “nearly identical”
    language under the FAL, see § 17535, grants a court
    discretion to order restitution. Cortez v. Purolator Air
    Filtration Prods. Co., 
    23 Cal. 4th 163
    , 173 (2000).
    may or may not have alerted customers that a damage waiver was an
    optional purchase). Google argues that the facts here present an example
    of disparate exposure under this line of cases. Pulaski responds that
    Google’s deception was pervasive: all AdWords customers could select
    Search Feed pages, Content Network pages, or both; parked domain and
    error pages were never mentioned in AdWords’s sign-up materials;
    Google’s contracts with advertisers never disclosed that Google would
    place their ads on parked domains and error pages, regardless of whether
    they chose Search Feed pages, Content Network pages, or both; and
    Google’s materials answering frequently asked questions did not disclose
    ad placement on parked domain and error pages. Because Pulaski’s claim
    rests on allegations of deception through omission and falsehoods via the
    AdWords sign-up materials, all of which were presented to putative class
    members through the same online portal, Google’s argument that disparate
    information defeats predominance is unpersuasive.
    14          PULASKI & MIDDLEMAN V. GOOGLE
    Thus, a court need not make individual determinations
    regarding entitlement to restitution. Instead, restitution is
    available on a classwide basis once the class representative
    makes the threshold showing of liability under the UCL and
    FAL. Accordingly, the district court erred in holding that
    such individual questions would predominate.
    B.
    We held in Yokoyama that “damage calculations alone
    cannot defeat certification.” 
    594 F.3d at 1094
    . By
    concluding that it was not bound by Yokoyama under the
    circumstances presented in this case, the district court erred.
    Yokoyama concerned the Hawaii Deceptive Practices Act,
    Haw. Rev. Stat § 480–2. We concluded that the district court
    erred when it held that this law required individualized
    showings of reliance because Hawaii courts’ caselaw
    “look[ed] to a reasonable consumer, not the particular
    consumer.” Id. at 1092. As we noted, the case, at the liability
    stage, would “not require the fact-finder to parse what oral
    representations each broker made to each plaintiff.” Id. at
    1093. Rather, the liability portion would be uniform, as it
    “will focus on the standardized written material given to all
    plaintiffs to determine whether those materials are likely to
    mislead consumers acting reasonably under the
    circumstances.” Id. Because it committed legal error, its
    denial of class certification was a “[p]er [s]e [a]buse of
    [d]iscretion.” Id.
    The district court in Yokoyama also erroneously
    concluded that the “damages calculation involved highly
    individualized and fact-specific determinations,” a conclusion
    to which the district court’s premise of subjective reliance
    PULASKI & MIDDLEMAN V. GOOGLE                   15
    may have contributed. Id. In examining predominance for
    class certification purposes, the district court had considered
    factors such as:
    the financial circumstances and objectives of
    each class member; their ages; the [indexed
    annuity product (“IAP”)] selected; any
    changes in the fixed interest rate for that
    particular IAP; the performance of the
    selected index; any changes in the index
    margin for that particular IAP; any cap on the
    indexed interest; the length of the surrender
    periods; whether the individual had
    undertaken or wanted to undertake an early
    withdrawal of funds; any benefit the
    individual policy holder derived from the
    form of the annuity itself, including the tax-
    deferral of credited interest; and the actual
    rate of return on the IAP.
    Id. at 1093–94. We held that, even though all these variables
    impacted damages calculations, the individualized
    calculations did not defeat predominance. Id. at 1093; see
    also Stearns, 
    655 F.3d at 1026
     (“We have held that the mere
    fact that there might be differences in damage calculations is
    not sufficient to defeat class certification.” (citing
    Yokoyama)).
    Google argues that Comcast Corp. v. Behrend, — U.S.
    —, 
    133 S. Ct. 1426
     (2013), called Yokoyama’s holding into
    question. There, in analyzing a putative antitrust class, the
    Court held that the plaintiffs’ proposed damages model fell
    “far short of establishing that damages are capable of
    measurement on a classwide basis.” 
    Id. at 1433
    . The district
    16          PULASKI & MIDDLEMAN V. GOOGLE
    and circuit courts had failed to inquire into whether the model
    translated the “legal theory of the harmful event into an
    analysis of the economic impact of that event.” 
    Id. at 1435
    (emphasis omitted). The Court reasoned that “a model
    purporting to serve as evidence of damages in [a] class action
    must measure only those damages attributable to that theory.
    If the model does not even attempt to do that, it cannot
    possibly establish that damages are susceptible of
    measurement across the entire class for purposes of Rule
    23(b)(3).” 
    Id. at 1433
    . In such a situation, “[q]uestions of
    individual damage calculations will inevitably overwhelm
    questions common to the class.” 
    Id.
    Since Comcast, we have continued to apply Yokoyama’s
    central holding. In Levya v. Medline Industries, Inc., we
    reaffirmed that damage calculations alone cannot defeat class
    certification. 
    716 F.3d 510
    , 513–14 (9th Cir. 2013) (citing
    Yokoyama). We explained that Comcast stood for the
    proposition that “plaintiffs must be able to show that their
    damages stemmed from the defendant’s actions that created
    the legal liability.” 
    Id. at 514
    ; see also Roach v. T.L. Cannon
    Corp., 
    778 F.3d 401
    , 407 (2d Cir. 2015) (“Comcast held that
    a model for determining classwide damages relied upon to
    certify a class under Rule 23(b)(3) must actually measure
    damages that result from the class’s asserted theory of injury;
    but the Court did not hold that proponents of class
    certification must rely upon a classwide damages model to
    demonstrate predominance.”). The putative class’s problem
    in Comcast was that the damages model “did not isolate
    damages resulting from any one theory of antitrust impact.”
    Levya, 715 F.3d at 514 (quoting Comcast, 133 S. Ct at 1431).
    Following this discussion, we reversed a denial of class
    certification in part because the “damages could feasibly and
    PULASKI & MIDDLEMAN V. GOOGLE                             17
    efficiently be calculated once the common liability questions
    are adjudicated.” Id.
    We reaffirmed the proposition that differences in damage
    calculations do not defeat class certification after Comcast in
    Jimenez v. Allstate Insurance Co., 
    765 F.3d 1161
    , 1167 (9th
    Cir. 2014) (quoting Levya, including the portion quoting
    Yokoyama). As we explained, our sister circuits have adopted
    “[s]imilar positions” since Comcast. See 
    id.
     at 1167–68
    (citing cases from the Sixth, Seventh, and Fifth Circuits); see
    also Roach, 778 F.3d at 407–08 (citing cases from the First,
    Tenth, Fifth, Seventh, and Sixth Circuits, as well as Levya
    and Yokoyama, to support the proposition that Comcast did
    not hold that Rule 23(b)(3) requires a classwide basis for
    damages calculation).
    In sum, Yokoyama remains the law of this court, even
    after Comcast. Because “[d]amages calculations alone . . .
    cannot defeat certification” under Yokoyama, the district court
    erred in concluding that Yokoyama “does not apply to the
    facts here.” Thus, it abused its discretion in denying class
    certification on this basis. See Yokoyama, 
    594 F.3d at
    1090–92.8

    Google also argues that the Supreme Court’s decision in Dukes bars
    class certification here because, under Dukes, certification is inappropriate
    based on a lone common question. However, this argument is contrary to
    Dukes, which stated that “for the purposes of Rule 23(a)(2), even a single
    common question will do.” 
    131 S. Ct. at 2556
    . Further, the plaintiffs in
    Dukes were pursuing a Rule 23(b)(2) class, rather than a (b)(3) class. 
    Id.
    at 2548–49. As the Court made clear, it did not analyze Rule 23(b)(3).

    C.
    Google argues that the district court properly denied
    Pulaski’s motion for certification under Comcast because the
    proposed method for calculating restitution was “arbitrary,”
    and thus does not satisfy Rule 23(b)(3)’s predominance
    requirement. See Comcast, 
    133 S. Ct. at 1433
    . We disagree.
    Restitution is “the return of the excess of what the
    plaintiff gave the defendant over the value of what the
    plaintiff received.” Cortez, 
    23 Cal. 4th at 174
    . Restitution
    has two purposes: “to restore the defrauded party to the
    position he would have had absent the fraud,” and “to deny
    the fraudulent party any benefits, whether or not
    for[e]seeable, which derive from his wrongful act.” Nelson
    v. Serwold, 
    687 F.2d 278
    , 281 (9th Cir. 1982) (citing the
    Restatement of Restitution).
    Restitution under the UCL and FAL “must be of a
    measurable amount to restore to the plaintiff what has been
    acquired by violations of the statutes, and that measurable
    amount must be supported by evidence.” Colgan v.
    Leatherman Tool Grp., Inc., 
    135 Cal. App. 4th 663
    , 698
    (2006). Where a defendant has wrongfully obtained a
    plaintiff’s property, “the measure of recovery for the benefit
    received . . . is the value of the property at the time of its
    improper acquisition . . . or a higher value if this is required
    to avoid injustice” where the property has changed in value.
    
    Id.
     at 698–99 (quoting the Restatement of Restitution).
    Where plaintiffs are “deceived by misrepresentations into
    making a purchase, the economic harm is the same: the
    consumer has purchased a product that he or she paid more
    for than he or she otherwise might have been willing to pay
    if the product had been labeled accurately.” Kwikset, 51 Cal.
    PULASKI & MIDDLEMAN V. GOOGLE                  19
    4th at 329 (emphasis in original). As the California Supreme
    Court explained while discussing economic harm in the
    context of standing, this measure “is the same whether or not
    a court might objectively view the products as functionally
    equivalent”:
    Two wines might to almost any palate taste
    indistinguishable–but to serious oenophiles,
    the difference between one year and the next,
    between grapes from one valley and another
    nearby, might be sufficient to carry with it
    real economic differences in how much they
    would pay. Nonkosher meat might taste and
    in every respect be nutritionally identical to
    kosher meat, but to an observant Jew who
    keeps kosher, the former would be worthless.
    
    Id.
     at 329–30. Applying these concepts to other forms of
    fraudulent omission, UCL and FAL restitution is based on
    what a purchaser would have paid at the time of purchase had
    the purchaser received all the information.
    In calculating damages, here restitution, California law
    “requires only that some reasonable basis of computation of
    damages be used, and the damages may be computed even if
    the result reached is an approximation.” Marsu, B.V. v. Walt
    Disney Co., 
    185 F.3d 932
    , 938–39 (9th Cir. 1999). “[T]he
    fact that the amount of damage may not be susceptible of
    exact proof or may be uncertain, contingent or difficult of
    ascertainment does not bar recovery.” 
    Id. at 939
    .
    We conclude that Pulaski’s proposed method was not
    “arbitrary,” as Google argues. The calculation need not
    account for benefits received after purchase because the focus
    20            PULASKI & MIDDLEMAN V. GOOGLE
    is on the value of the service at the time of purchase. Instead,
    in calculating restitution under the UCL and FAL, the focus
    is on the difference between what was paid and what a
    reasonable consumer would have paid at the time of purchase
    without the fraudulent or omitted information. See Kwikset,
    
    51 Cal. 4th at 329
    .
    Here, the harm alleged is Google’s placement of ads on
    lower-quality web pages without the advertisers’ knowledge.
    Pulaski’s principal method for calculating restitution employs
    Google’s Smart Pricing ratio, which directly addresses
    Google’s alleged unfair practice by setting advertisers’ bids
    to the levels a rational advertiser would have bid if it had
    access to all of Google’s data about how ads perform on
    different websites. Because restitution under the UCL and
    FAL measures what the advertiser would have paid at the
    outset, rather than accounting for what occurred after the
    purchase, using a ratio from Google’s data that adjusts for
    web page quality is both targeted to remedying the alleged
    harm and does not turn on individual circumstances. Thus,
    the Smart Pricing method measures the monetary loss
    “resulting from the particular . . . injury” alleged. See
    Comcast, 
    133 S. Ct. at 1434
    .9
    IV. Conclusion
    The district court erred by conflating restitution
    calculation with the liability inquiry for UCL and FAL
    claims, and by failing to follow our rule in Yokoyama.

    Although we do not directly analyze the Content Pricing or the Full
    Refund approaches, those methods may also be appropriate for calculating
    restitution. We express no opinion on the merits of any of the proposed
    methods.
