A suspected brand-bidding violation needs evidence of the ad, the publisher and the applicable restriction. A rise in affiliate commissions or an unusually high conversion rate may justify a closer look, but neither proves misconduct. Start with the facts of a specific referral before deciding whether enforcement is warranted.
Use the right search data
Google Search Console reports organic search clicks, impressions, click-through rate and average position. It does not provide a branded paid-search impression-share metric. A decline in organic impressions cannot establish that an affiliate bought a prohibited keyword or caused a particular commission.
Build a transaction-level record
Record the search query, ad text, visible destination, date, market and device when you observe a suspected ad. Where you have authorized access, compare paid-search reports and referral records with the publisher account and order identifiers. Ask your network which click-path details it can provide. Preserve the evidence and note any gaps instead of assuming every network exposes the same reports.
Apply the actual agreement
Check whether the terms prohibit bidding, trademark use in ad copy, particular destinations or specific keyword matches. These are different restrictions. Use the agreement in force for the transaction and give the partner a chance to explain the traffic source. Commission reversals or termination should follow substantiated findings and the applicable contract, not an automatic conversion-rate threshold.
Make monitoring useful
Assign someone to review suspected incidents and keep a dated case log. Compare recurring patterns, resolve false positives and update unclear program language through your normal review process. The goal is to protect legitimate referrals while enforcing rules consistently.
An ad is a lead to investigate, not a completed case
In a fictional review, a manager searches the brand name and sees an unfamiliar advertiser above the organic result. Save the query, date, location and visible ad. The ad alone does not identify an affiliate or prove a contractual breach. Ask the network to connect any relevant referral identifier to an account before taking action.
Turn the finding into a clear rule
Check whether your agreement covers exact brand terms, misspellings, brand-plus-coupon phrases and direct linking. If a rule is missing, draft it prospectively and use the normal notice process. A paid-search report and an organic Search Console report answer different questions; do not use one as a substitute for the other.
