Post Affiliate Pro Warns Merchants of Rising Brand Bidding Risks in Search Ads

Post Affiliate Pro warns that affiliates increasingly use search engine marketing (SEM) to intercept high-intent traffic through brand bidding. The practice often forces advertisers to pay commissions for sales that would likely occur organically.

Affiliates bid on a company’s trademarked keywords or product names. When a consumer searches for the brand, they click an affiliate-sponsored ad rather than the merchant’s organic listing. The affiliate then earns a commission, effectively taxing the merchant’s existing brand equity.

Hidden Costs of Redundant Traffic

Performance dashboards often show rising sales and high conversion rates for these affiliates. However, Post Affiliate Pro notes that the true cost remains hidden. The data represents a misallocation of marketing budget. In this scenario, merchants pay commissions to partners who do not generate new demand but merely capture it at the final stage of the customer journey.

Aggressive brand bidding also drives up the Cost-Per-Click (CPC) for the merchant’s own internal search campaigns. Merchants find themselves forced to bid against their own partners for the top ad spots.

The affiliate who captures that click is not creating demand. They are standing between a customer who has already chosen you and your website, and collecting a commission for it.

Google Ads and Trademark Realities

A common misconception among brand owners is that search engines or trademark laws automatically prevent this behavior. Post Affiliate Pro notes that Google Ads policy does not restrict the use of trademarks as keywords. While merchants can restrict trademark use in ad copy, the underlying keywords used to trigger the ad remain open for bidding on major search platforms.

Manual Searches and Auction Insights

To combat unauthorized brand bidding, Post Affiliate Pro recommends a multi-layered detection approach. Affiliate managers should perform manual searches for their own brand terms, including common misspellings and "brand + coupon" variations, rather than relying solely on automated reports.

Advanced detection methods include:

• Auction Insights: Monitoring Google Ads reports to see which domains compete for brand keywords.
• Referrer URL Analysis: Checking the source of incoming traffic for suspicious redirect chains.
• Keyword Reporting: Using affiliate software to identify which search terms drive clicks through affiliate links.

A robust Affiliate Service Agreement serves as the most effective prevention tool. Post Affiliate Pro suggests that terms should explicitly forbid bidding on brand terms and specify an "enforcement ladder." This process typically begins with a formal warning and evidence, followed by the reversal of commissions, and finally, the termination of the affiliate partnership. By establishing clear boundaries, brands ensure their affiliate budget funds genuine customer acquisition rather than redundant commissions.
