Brand Bidding: The PPC Policy Every Affiliate Program Needs in Writing

Type your own brand name into a search engine. If an ad sits above your organic listing and its destination is your site via an affiliate link, you are paying commission on customers who searched for you by name — traffic that would have arrived free one click lower. Brand bidding is the most expensive affiliate behavior most owners never look for, and the fix starts with a sentence in your terms.

Why it works on you, specifically

Brand-term clicks are the cheapest, highest-converting traffic in existence: the searcher already decided, they're just navigating. An affiliate who bids on "YourBrand" or "YourBrand discount" buys that navigation for cents, routes it through their link, and collects your commission on sales that were already yours. It's the paid-search sibling of checkout coupon interception — no demand created, pure toll collection — with a bonus harm: if you run brand ads yourself, the affiliate is now your auction competitor, driving up your own cost per click.

None of this makes paid-traffic affiliates bad partners. An affiliate running ads on generic terms — "affiliate plugin for WooCommerce," "how to track referrals" — is creating demand with their own money and deserves every commission. The policy question is only about your name.

The clause to write

Your program terms need four specific prohibitions, because vague "no trademark abuse" language invites creative readings:

1. No bidding on the brand name, product names, or misspellings and variations of either — the misspellings clause matters, "YuorBrand" traffic is still navigation.
2. No brand terms plus modifiers: "-coupon," "-discount," "-review," "-alternative." These are where most real-world violations live.
3. No using the brand name in ad display URLs or ad copy in ways that read as official.
4. No direct linking from paid ads to your site through an affiliate link — ads must land on the partner's own content first. This one rule incidentally blocks most lazy arbitrage.

State the consequence with the rule: first violation is a warning and forfeiture of the affected commissions; second is removal. Enforcement you won't do is policy you don't have.

Detection is a calendar habit

Nobody reports brand bidders — you find them. The routine takes ten minutes a month: search your brand and its obvious variants ("brand coupon," "brand review," a misspelling or two) in an incognito window, ideally from a couple of locations or a VPN since ads geo-target, and click any suspicious ad to see whether an affiliate parameter rides the landing. Ad-transparency tools that show a domain's active ads help widen the sweep.

Circumstantial signals in your own data help too: a partner whose referrals spike with no visible content, whose conversion rate looks too clean, or whose traffic arrives in tight bursts that match ad-schedule patterns deserves a closer look — the same instincts as general fraud review. If your tracking records landing context on visits, the pattern of paid-search referrers gives the conversation its evidence; an audit trail turns "we suspect" into "on these dates, these referrals."

Enforcement without drama

Most violators, confronted, claim confusion — sometimes sincerely, since a few large programs do permit brand bidding. Which is exactly why the written clause matters: the conversation is "our terms, section 6, here are the referrals affected, commissions forfeited, please confirm the campaigns are off" — calm, documented, finished. Partners watching how you enforce learn whether your rules are real, and the good ones prefer programs where they are: every dollar a brand bidder extracts comes from the budget that funds honest partners' rates and bonuses.

Put the clause in this week; do the ten-minute search this month. The whole problem is invisible until you look — and usually over the week after you do.
