Google Ad Claims
Google ad claims

The Google advertising
lawsuits, explained.

What the courts found, why advertisers are seeking compensation, and what it could mean for your business.

Case explainer · Sources reviewed

The case in brief

Advertisers are seeking compensation on the basis that Google’s restrictions on competition caused them to pay too much for advertising.

  • Two federal cases provide the foundation. One concerns Google Search and text ads; the other concerns the technology used to sell display ads on third-party websites.
  • The courts found unlawful conduct. Those findings support further investigation of advertiser losses, but do not calculate what any particular business is owed.
  • Compensation requires a separate claim. Your ad products, spending history, contracts and evidence of harm determine whether and how you can pursue recovery.

The government cases seek changes to Google’s conduct. Private advertiser claims seek money for past harm. In May 2026, Keller Postman reported representing thousands of U.S. businesses pursuing alleged overcharges through coordinated arbitration. That announcement describes claims being pursued, rather than a completed payout.

What did the courts find?

Search: how Google kept its position and raised prices

On August 5, 2024, Judge Amit Mehta in Washington, D.C. found that Google unlawfully maintained monopolies in general search services and general search text advertising. Agreements making Google the default search engine on browsers and devices restricted rivals’ ability to compete.

The opinion also found that Google charged text-ad prices above competitive levels. It describes auction adjustments, including “squashing,” that increased the pressure on a leading bidder to pay more. The court’s finding concerns a specific advertising market; it does not establish that every Google advertising product was monopolized.

Ad tech: the systems between advertisers and websites

On April 17, 2025, Judge Leonie Brinkema in Virginia found that Google unlawfully monopolized the publisher ad-server and ad-exchange markets for open-web display advertising, and unlawfully tied its products together.

A publisher ad server helps a website decide which ad to show. An exchange runs the auction for that space. Google’s products, DFP and AdX, occupied both positions. The court found that forcing these tools together and restricting competition harmed the market. It rejected the government’s separate proposed advertiser ad-network market, so the decision should not be read as a finding against every part of Google’s advertising business.

What changed after the liability rulings?

  • September 2025 — Search remedies. The court ordered restrictions on exclusive distribution arrangements and requirements for sharing certain search data and services with competitors. The DOJ record lists a final judgment dated December 5, 2025.
  • January 2026 — Google’s Search appeal. Google announced its appeal on January 16. It argues that users choose Google for its quality and that the ruling understates competition.
  • September 2026 — Ad-tech remedies. The court ordered integration with competing systems, access to publisher data, restrictions on preferential bidding, and oversight for six years. As our September case update explains, the court declined to order the breakup sought by the DOJ.

These developments concern market conduct and the government litigation. They do not set a payment date for an individual advertiser.

How does this relate to your ad spend?

The advertiser’s argument is straightforward: with more effective competition, the price of reaching customers would have been lower. The claimed loss is the extra amount paid because of the unlawful conduct. An ad campaign can generate sales and still have cost more than it should have.

For Search advertisers, the relevant evidence includes auction pricing and Google’s ability to raise prices without losing business to rivals. For display advertisers, the inquiry concerns the systems and fees between the advertiser and the website. Our September update discusses the court’s treatment of AdX’s long-running 20% exchange fee and lower fees at rival exchanges. An exchange fee is not itself a measurement of your overcharge.

Your records connect the market-wide findings to your business. A claim still needs to establish which purchases were affected, whether the business owns the claim, and how much loss the conduct caused.

Who may have a claim?

A U.S. business with historical Google Search advertising spend is a sensible starting point for a review. Silver Arbitration’s assessment asks about spending from August 2016 onward. Keller Postman also identifies that starting period in its public intake materials. This is an assessment window, not a court-created guarantee that every purchase in that period qualifies.

  • Past advertising counts. You can ask about an account that is no longer active or only advertised during part of the period.
  • The product matters. Separate Search text ads from Display, Shopping and YouTube. Mixed campaigns such as Performance Max need a closer look; the whole Google Ads bill should not automatically be treated as eligible Search spend.
  • The business and contract matter. The paying entity, applicable U.S. terms, account ownership and any sale or reorganization of the business need review.

What if an agency managed the account?

Agency management does not by itself rule out a claim. Explain who contracted with Google, who paid, and whether the agency billed the client for media. Our team reviews those arrangements before deciding who may bring the claim. An agency’s total managed spend should not be treated as one claim belonging to the agency.

Why arbitration, and why work with a law firm?

Arbitration is a process in which a neutral arbitrator decides a dispute outside court. Many Google Ads agreements require individual arbitration and waive participation in a class action. The applicable agreement and any valid opt-out determine the available route.

“Mass arbitration” describes coordinated claims from many customers. Each business still needs evidence supporting its own claim. The July 2026 Google Ads terms also contain batching procedures for similar demands; older terms may govern some disputes. The process depends on the terms that apply to the account.

Sources: Google Ads terms, section 13; AAA’s explanation of mass arbitration; our mass arbitration explainer.

A law firm turns an account history into a supported legal claim. That work includes checking ownership and deadlines, identifying the applicable contract, analyzing losses, preparing notices and filings, responding to Google’s defenses, and advising on any settlement offer. Coordinating common legal and economic work can make individual claims more practical to pursue.

Your role is to provide accurate information, help locate records, answer questions when needed, and decide whether to accept a settlement. Some claims may require more involvement if evidence or a hearing is needed.

What could you recover, and what does it cost?

A potential recovery starts with the loss that can be supported by evidence. Federal antitrust law provides for three times proven damages for qualifying claims, often called treble damages, as well as reasonable attorney’s fees. A settlement can reflect litigation risk and need not equal the amount sought.

Source: 15 U.S.C. § 15.

Silver Arbitration works on a fixed contingency fee: no out of pocket expense and no fee if there is no recovery. Review the engagement agreement for the fee percentage, treatment of expenses, and how any recovery is distributed. The amount claimed, the amount recovered and the amount you receive after fees are different figures.

See how claim value is assessed and our case update and fee description.

How long could it take, and why act now?

There is no confirmed settlement date for your business. An initial assessment is only the beginning; gathering records, serving notices, dealing with procedural disputes, evaluating damages and negotiating or presenting a claim take additional time. A contested case can take substantially longer than an early negotiated resolution, and a claim may end without recovery.

The July 2026 Google Ads terms provide a 60-day notice period before an arbitration demand can be filed. That is a procedural waiting period, not a promise that a case will settle in 60 days. Counsel must check which version of the terms governs your claim.

Filing time limits make an early review useful. Federal antitrust damages claims generally have a four-year limitation period, but rules that pause the clock, including for certain related government proceedings, can change the analysis. State-law claims and contractual issues may differ. Do not calculate your deadline simply by adding four years to an invoice or assuming the government’s case protects every claim.

What should you have ready?

Your name and email are enough to request an assessment. For the later review, keep what you already have and identify any gaps:

  • Google Ads customer IDs, business names and the years you advertised.
  • Campaign spending reports that distinguish advertising products and periods.
  • Invoices, payment records and any agency billing agreements.
  • Relevant account terms, opt-out records, and documents for any business ownership changes.

You do not need to calculate damages yourself. Our team can help identify and organize the records. Share client information only with permission. Read the preparation checklist or our Search spend reporting guide.
