Affiliate and advertiser ads competing on the same brand keyword

Brand bidding in affiliate marketing means an affiliate buys search ads on the advertiser's brand name (for example "[brand] discount" or just "[brand]") and sends that traffic through their affiliate link. Many advertisers restrict or ban it because those searchers already know the brand, so the advertiser may pay commission on customers it would have won anyway.

Key takeaways

  • Brand bidding can raise the brand's own ad costs and claim commission on existing demand.
  • Programs usually ban it, allow it only with approval, or allow it on specific terms.
  • "TM+" means brand name plus another word (for example "[brand] coupon").
  • Clear written rules and monitoring prevent most disputes.

Why advertisers restrict brand bidding

  • Paying twice: the brand may pay for the click and the affiliate commission.
  • Higher CPCs: affiliates bidding on the brand compete with the brand's own ads.
  • Low incrementality: searchers looking for the brand were likely to buy anyway.
  • Brand control: ad copy may not match the brand's messaging.

Common brand bidding policies

PolicyMeaning
No brand biddingNo ads on brand terms, misspellings or TM+ terms
Negative keywords requiredAffiliates must add brand terms as negatives in their campaigns
Approved onlyAllowed for specific partners and geos with written approval
No direct linkingAds cannot send users straight from the ad to the advertiser's site

When brand bidding can make sense

Some advertisers allow selected partners to bid in markets where the brand does not advertise, or on specific TM+ terms, with clear limits on budget, geos and ad copy.

How to monitor compliance

  • Regular manual searches in key markets and devices.
  • Brand monitoring tools that capture ads shown on your terms.
  • Reviewing referrer and sub ID data for suspicious paid search traffic.

Conclusion

Brand bidding is not illegal in itself, but in affiliate programs it is a policy decision. Advertisers should state rules clearly; affiliates should follow them exactly or ask first. See our Affiliate Compliance Guide and Google Ads for Affiliates.
