Is brand bidding illegal?

Not automatically. Google Ads says it does not restrict the use of trademarks as keywords, and under the US federal trademark statute (15 U.S.C. § 1114) the question is whether the use is likely to cause confusion. Whether a specific ad crosses that line is a legal question, so speak to a trademark attorney before taking legal action.

What is the difference between brand bidding and trademark bidding?

Trademark bidding means bidding on a registered trademark as an advertising keyword. Brand bidding is the broader everyday term that also covers product names and spelling variations. In affiliate program rules the two terms are often used for the same practice, so name the exact terms you prohibit instead of relying on either label.

Why do affiliates bid on a merchant's brand name?

People who search for a brand by name are usually close to buying. An affiliate who shows an ad on that search and sends the click through a tracking link can collect a commission for a sale that may have happened anyway. It takes less effort than creating content that brings in new customers.

What is defensive brand bidding?

Defensive brand bidding is when a merchant runs search ads on its own brand name so that it holds the ad space when someone searches for it. It gives the merchant control over the ad text and landing page, but it can also mean paying for clicks the free listing would have received anyway, so the result is worth testing rather than assuming.

What is the difference between brand bidding and competitor bidding?

In brand bidding, someone bids on a brand's own name, and in affiliate marketing that is usually an affiliate bidding on the merchant's brand. In competitor bidding, a rival bids on your brand terms to show its own ad to your audience. An affiliate has an agreement with you, so your program rules apply. A competitor does not, so your options are the platform's complaint process and your own advertising.

Should a merchant pay commission on branded search traffic?

That is a business decision. A merchant can ban brand bidding, allow it only for approved partners under written conditions, or allow it and accept paying commission on demand it already had. The right choice depends on margins, how much branded traffic the merchant already gets and whether the affiliate adds real value.

How can a merchant stop affiliates from brand bidding?

Search platforms will not stop it for you, so the main control is your own program. Write a specific brand bidding clause into your affiliate terms, require affiliates to accept it, review commissions before they are paid and apply the consequences you stated in advance.

What is brand bidding?

Brand bidding is paying for search ads on a brand’s name, which in affiliate marketing means earning commission on customers who were already looking for the merchant.

BrandBidding AffiliateMarketing PaidSearch BrandProtection

Brand bidding is paying for search ads that appear when someone searches for a brand’s name, its product names or close variations of them. The advertiser chooses the brand term as a keyword, and the ad shows above or beside the search results whenever that term is searched.

In affiliate marketing the term usually describes one situation: an affiliate bids on the merchant’s brand name and uses their affiliate tracking link as the ad’s destination. Someone who was already looking for the merchant clicks the ad, passes through the link and buys, and the affiliate earns a commission on a customer the merchant had a good chance of winning without them.

This entry defines brand bidding, explains how it works and who does it, and clears up common misunderstandings. To detect it, set a policy and stop it, read the full guide on brand bidding in affiliate marketing .

What is brand bidding?

The core definition

Brand bidding is a paid search tactic built on branded keywords. The advertiser pays to show an ad when a person searches for a brand, and in most ad systems pays when the ad is clicked, which is the pay per click (PPC) model. The brand being searched for is not always the advertiser’s own, and that is what makes the term matter in affiliate marketing.

What counts as a brand term

A brand term is any search phrase that points to a specific company. It goes beyond the company name:

The company name, alone or with words people add when they are ready to act, such as login, pricing, discount or coupon.
Product and service names, including the names of plans or features.
Misspellings and spacing variations of the name, for example a missing letter or a name written as two words.
Domain-style searches, where people type the website address into the search box.

A rule that only covers the company name leaves the rest open, which is why programs that restrict brand bidding list every term they mean.

Brand bidding and branded search

Branded search is the other side of the same coin. It is the behavior: people type a brand into a search engine. Brand bidding is the advertising decision to pay for a place on those searches. A person can find your site through your free listing for the brand, or through a paid ad that someone bought on it. The searcher usually cannot tell who paid, and the merchant sees the difference only in their data.

How affiliate brand bidding works

The affiliate joins your program and receives a tracking link.
They build a search ad campaign with your brand name, product names or variations as keywords.
A person searches for your brand and sees the affiliate’s ad.
The person clicks. The click runs through the affiliate’s tracking link, the system records it and the visitor lands on your site.
The person buys. Under last-click attribution, the affiliate whose click came last receives the credit and the commission.

For the customer almost nothing changes. For the merchant’s data a lot does: a sale that began with a search for the merchant’s own name is now recorded as a sale generated by an affiliate.

A simple example

An illustrative case, with made-up numbers. A merchant pays 10% commission. A customer searches for the merchant’s name, clicks an affiliate’s ad and buys a 100 USD order, so the affiliate earns 10 USD. If the customer was going to buy anyway, the merchant has paid 10 USD for a sale that needed no affiliate. The merchant’s affiliate report also shows that sale as affiliate revenue, even though the affiliate did not create the demand.

Who bids on brand names

Three different parties bid on brand names, with different effects for the merchant.

Merchants

A merchant can bid on its own brand name so that it, not someone else, holds the ad space when a customer searches for it. This is sometimes called defensive brand bidding. It gives control over the ad text and the landing page. The cost is that the merchant may pay for clicks its free listing would have received anyway. Whether the ads add sales can be tested, for example with Google Ads experiments, which split budget or traffic between an original campaign and a changed version (Google Ads Help ).

Affiliates

An affiliate who bids on the merchant’s brand does it because the click is cheap to win and the visitor is already close to buying. The affiliate does not have to create content, build an audience or persuade anyone. Many programs ban it in their terms and allow it only for approved partners under written conditions.

Competitors

A competitor can bid on your brand terms to show its own ad to people looking for you. A competitor has no agreement with you, so your rules for affiliates do not apply. Your options are the platform’s complaint process for ad text and your own advertising.

Brand bidding, trademark bidding and competitor bidding

People use these terms loosely.

Term	What it means	Who bids on whose brand
Brand bidding	Bidding on a brand’s name, product names and variations as search keywords	Usually an affiliate bidding on the merchant’s brand
Trademark bidding	Bidding on a registered trademark as a keyword	Sometimes used for the same practice in affiliate program rules
Defensive brand bidding	Bidding on your own brand terms to hold the ad space	A merchant bidding on its own brand
Competitor bidding	Bidding on a rival’s brand terms to show your own ad to their audience	A competitor bidding on your brand

Why merchants care

When a merchant has not agreed to it, brand bidding creates five problems:

Commission for sales you may have made anyway. The search began after the customer had already decided to look for you.
Distorted reporting. Branded conversions credited to the affiliate channel make that channel look more productive than it is.
Paying twice. If you also run ads on your brand, an affiliate’s ad on the same search means you pay to reach one customer through two routes.
Less reward for affiliates who build demand. Reviewers and content creators earn less relative to those who only buy the brand keyword.
Unapproved ad text. Affiliate ads on your name can carry offers or claims you have not approved.

Not every merchant treats it as a problem. Some allow it for approved partners, and the full guide compares the three policy options: a full ban, conditional permission and full permission.

Is brand bidding allowed?

Google Ads says it does not restrict the use of trademarks as keywords. It may restrict trademarks in ad text in certain situations, for example when a direct competitor uses the mark or when the use is confusing, deceptive or misleading, and trademark owners can submit a complaint (Google Ads trademark policy ).

In the United States, the federal statute on infringement of registered marks makes actionable the use in commerce of a registered mark in connection with advertising goods or services where that use “is likely to cause confusion, or to cause mistake, or to deceive” (15 U.S.C. § 1114 ). The test is confusion, not simply that someone else used your name. This is general information, not legal advice, and a trademark attorney can tell you whether a specific ad crosses the line.

Because neither the platform nor the law reliably settles the question in a merchant’s favor, the dependable control is the rule in your own affiliate agreement .

Common misconceptions

“Brand bidding is always illegal.” It is not automatically. The platform allows trademarks as keywords, and the legal test is confusion, which depends on the facts of each ad.

“If I ban PPC, I have banned brand bidding.” A blanket ban on paid search is broader than most merchants intend. A clear rule names the brand terms and the ad text rules instead.

“If sales are rising, it is working.” Sales credited to a brand-bidding affiliate may have happened anyway. Judge branded campaigns on total branded sales from all sources, not on what one channel reports.

“The search engine will stop my affiliates.” The platform does not restrict trademarks as keywords. You have a complaint route for misleading ad text, but the main control is your own program.

“Only the company name counts.” Product names, misspellings and name-plus-action phrases are brand terms too.

How merchants keep control

A program that wants to control brand bidding needs the same four building blocks:

A written rule in the affiliate agreement that names the brand terms and states the consequences.
Acceptance of the rule by every affiliate, including those who joined before it existed.
Monitoring through your own brand searches and the keyword and click data in your affiliate software.
Consistent enforcement: a warning with evidence, declined commissions, then removal.

In Post Affiliate Pro, the Keywords Performance report shows clicks by search keyword and can be filtered by affiliate. Activate the feature first under Configuration > Features, because it records keywords only from activation onward. The step-by-step setup, the three policy options and a sample clause are in the brand bidding guide .

Pay per click (PPC) : the advertising model brand bidding runs on. The advertiser pays when the ad is clicked.
Keyword : the search term an ad is matched against. A brand term is a keyword that names a company.
Last click : the attribution model that gives the commission to the final click before a sale. It is what lets a brand-bidding affiliate collect commission.
Affiliate agreement : the contract where you set your brand bidding rule.
