Brand bidding is when an affiliate runs paid search ads on an advertiser's brand name — for example bidding on "AcmeBank" or "AcmeBank login" — and earns a commission when those searchers convert. Most advertisers prohibit it in their affiliate terms, because people searching for a brand by name were usually going to buy anyway. The advertiser ends up paying a commission for its own customers and competing against its own ads.
Why affiliates do it
Brand searches convert extremely well because the user already wants the product. An affiliate who captures that click with an ad and a tracking link can show a very high conversion rate and a low cost per sale. On paper, it looks like a great campaign. In reality, it rarely creates new demand.
Why advertisers ban it
- Paying for existing customers: the advertiser pays a commission on sales its own brand would have captured for free or at a lower cost through its own brand campaign.
- Higher click prices: affiliates bidding against the advertiser's own brand campaign push up the cost per click in the auction.
- Brand control: affiliate ads may use outdated offers, wrong claims or misleading copy under the brand's name.
- Attribution distortion: affiliate reports look strong while total business does not grow.
The common variations — and what terms usually say
| Practice | Example | Usually |
|---|---|---|
| Pure brand bidding | Ads on "brandname" | Banned |
| Brand + modifier | "brandname promo code", "brandname review" | Banned unless stated |
| Misspellings | "brnadname" | Banned |
| Direct linking | Ad lands directly on the advertiser's site with an affiliate link | Often banned on brand terms |
| Brand in ad copy | Using the trademark in the headline | Banned unless authorised |
| Competitor bidding | Bidding on a rival's brand for your offer | Depends on the offer and law; often restricted |
Some programmes allow limited brand bidding — for example on specific geos or on "brand + coupon" terms — but only with written permission and usually with bid caps.
How advertisers detect brand bidding
- Search monitoring tools that run searches across countries and devices, capture the ads shown and trace the landing URLs back to affiliate IDs.
- Search query reports in the advertiser's own Google Ads account, which show who else appears in the auction.
- Referrer and click data in the tracker or MMP: a sudden spike of conversions with paid-search referrers from one affiliate.
- Conversion patterns: extremely high conversion rates and brand-heavy traffic from a partner that claims to run content or social.
How to protect your programme
- Write it down. State in the offer terms that brand bidding, brand + modifiers, misspellings and trademark use in ads are not allowed, and what happens if someone does it.
- Share a negative keyword list that partners running search must add.
- Register your trademark with Google Ads so third parties cannot use it in ad text without authorisation (check Google's current trademark policy for your region).
- Monitor with search monitoring software and your own auction insights.
- Enforce consistently: reject commissions on violating traffic and remove repeat offenders.
Brand bidding and ClickSpero
We do not run or allow brand bidding unless an advertiser asks for it in writing. Every partner discloses their traffic sources before launch. It is part of the standard we describe on our advertisers page.
FAQ
Is brand bidding illegal?
Bidding on a keyword is generally not illegal in itself, but using a trademark in ad text, or causing confusion, can raise trademark issues depending on the country. In affiliate marketing the bigger risk is contractual: breaking the programme terms usually means losing commissions.
What is direct linking?
Direct linking means the ad sends the user straight to the advertiser's site through an affiliate link, with no page in between. Many programmes ban it on paid search, especially on brand terms.
Can I bid on competitor brand names?
It depends on the platform rules, local trademark law and the offer terms. Many advertisers restrict it too. Ask your affiliate manager before you run it.
How do I know if an offer allows brand bidding?
Read the offer restrictions and terms. If they are silent, ask your affiliate manager and get the answer in writing.
