Brand Bidding: How to Stop Affiliates From Bidding on Branded Keywords (Policy Template Included)

Search your own brand name in an incognito window right now. If the ad sitting above your organic listing isn’t yours, you’ve got a brand bidding situation; and if the advertiser turns out to be one of your own affiliates, you’re paying commission on buyers who were already typing your name into Google. I’ve spent years on the tracking side of affiliate programs, and this is the most common policy gap I see in programs that otherwise run beautifully. Happily, it’s also one of the most fixable.

Most of what ranks for “bidding on branded keywords” is written for PPC managers deciding whether to bid on their own name. This one’s for people already running an affiliate program: what affiliate brand bidding is, the math on what it actually costs you (worth seeing; it surprised me the first time I ran it), how to detect it, a copy-paste policy clause, and an enforcement ladder for when someone crosses the line anyway.

TL;DR: Brand bidding is running search ads against a brand name. When an affiliate does it on yours, they intercept buyers who were already searching for you and route them through an affiliate link, converting your cheapest traffic into commissioned sales. Google won’t stop it; its trademark policy explicitly doesn’t restrict trademarks used as keywords. Your affiliate agreement is the only enforcement surface you have, so put it in writing: ban the exact-match trademark, misspellings, and trademark-plus-modifier terms, require your brand as a negative keyword, and state that commissions earned from violating traffic are forfeit. Then enforce with a ladder: warn, withhold, terminate.

What is brand bidding?

Brand bidding means bidding on branded keywords in a search ad (PPC) auction: buying ads that show when someone searches a brand name. The term covers two very different activities, which is why half the pages ranking for it seem to be answering a different question than the one you asked.

The first sense is bidding on your own brand: the defensive play, where you run ads on your own name to hold the top of the page. The second sense is third parties bidding on your brand: competitors, resellers, arbitragers, and, the slice this guide covers, your own affiliates targeting branded keywords so the buyer’s last click before purchase carries their tracking parameter. The agency guides give that slice a single sentence. I think it deserves the whole article, because it’s the one form of brand bidding you’re directly paying for.

Brand bidding vs trademark bidding vs competitor bidding

These phrases overlap almost completely; the difference is who’s doing the bidding. Trademark bidding (or TM bidding) is brand bidding described from the legal side: bidding on trademarked keywords rather than a merely well-known name. Competitor bidding is a rival buying your name to poach the click. Here’s the full cast who might show up on your branded results page:

• Affiliates: your own partners intercepting bottom-funnel buyers for commission (this article)
• Competitors: rivals paying a premium for your demand
• Resellers and partners: often allowed, but they need explicit rules
• Franchisees and local partners: on your side, but off your leash without written rules
• Comparison and coupon sites: usually affiliates wearing a different hat
• Comparison shopping engines: feed-driven shopping ads that can surface against your name
• Arbitragers and lead gens: buying your clicks to resell the traffic or the lead

The detection methods below catch all of them. The policy template only governs the ones who signed your agreement, which is exactly why the affiliate slice is the most fixable one.

Why affiliates bidding on branded keywords silently tax your cheapest traffic

An affiliate bidding on your brand name converts traffic that should cost you almost nothing into fully commissioned sales. Branded search is the cheapest, highest-intent traffic your business will ever receive: these people already know your name and typed it on purpose. An affiliate who bids on it doesn’t bring you a single new customer. They step in front of buyers who were coming anyway and re-route them through an affiliate link, so a click that should’ve cost you nothing (organic) or pocket change (your own brand ad) now carries a full commission.

Now the fun part: let’s walk the math, because the numbers are what moved me from “etiquette question” to “written policy, today.” Suppose you sell a $49/mo product and pay affiliates 20% of year-one revenue, which is right in the normal range; just for reference, Notion’s affiliate program has paid up to $50 per activated signup plus 20% of year-one revenue. Say branded clicks convert at 8%, and your own brand ad costs an illustrative $0.60 per click (distinctive brand names often run well under $1, though your auction will vary).

Here’s what 100 branded clicks cost you, depending on which door the buyer walks through:

That last cell is 8 customers × $49/mo × 12 months × 20% = $940.80. The same 8 buyers, the same purchase intent, at more than 15× the cost of running the ad yourself; I love how cleanly that falls out of three inputs (price, commission, conversion rate). Flat bounties run the same play: at a Shopify-style up to $150 per qualified referral, those 8 intercepted sales would cost $1,200 per 100 clicks.

A second tax hides under the first, and it’s a sneaky bit of auction mechanics: the affiliate is now a competing bidder in your own brand auction, so even when you win the slot, their presence pushes up the price you pay for your own name. You’re funding both sides of that fight.

A third tax never shows up in a spreadsheet: what the ad actually says. An affiliate promising “70% off” you never offered, or running a display URL that imitates your domain, spends trust with the exact buyers who were most convinced, and the confused ones land in your support queue, so you pay for the same interception twice. That’s why clause 4 in the template below governs ad copy and display URLs, not just keywords.

Why Google will not stop it for you

Google won’t police brand bidding on your behalf, and that’s by policy, not neglect. Google’s trademark policy states plainly that it doesn’t investigate or restrict trademarks used as keywords; its restrictions apply to trademarks in ad text, and even those are only reviewed when the trademark owner files a complaint. You can read the policy at Google Ads Help.

So an affiliate bidding on your exact trademark, with an ad that never mentions your name in its text, is fully compliant with Google’s rules. Fair enough; Google runs an auction, not your program. The only agreement they’re breaking is yours, if yours says anything about it. Your affiliate terms are the one enforcement surface you actually control, which is the entire reason the policy template below exists, and honestly, a rule you write yourself is a rule you can enforce on your own schedule.

The last-click trick: why brand bidders look like your best affiliates

Here’s the twist I find genuinely interesting: in your dashboard, a brand bidder looks like a star. They intercept buyers at the very bottom of the funnel, seconds before purchase, so their conversion rate and earnings per click are spectacular. Under last-click attribution they get full credit for a sale your own marketing created. I’ve heard from more than one founder who nearly built a case study around their “top affiliate” before someone searched the brand name from a personal phone.

I’ve noticed the statistical tells are consistent, and once you know them they’re easy to spot:

• No top-of-funnel footprint. Genuine content affiliates show clicks spread across reviews and tutorials over weeks; a brand bidder’s clicks arrive minutes before conversion, with near-zero assisted or first-touch activity.
• Traffic that mirrors your ad schedule. Violators daypart around you: clicks spike on evenings, weekends, and whatever hours or regions your own brand campaign goes dark.
• Thin landing paths. Direct links or bridge pages rather than real content.

None of these is proof on its own. They’re the signal to run the detection steps below.

How to detect brand bidding against your program

Detection is a runbook, not a purchase, and I mean that as good news. Every vendor page on this topic funnels you toward a monitoring subscription, and those tools have a real place at scale, but a small program gets meaningful brand bidding protection with 20 minutes a week and zero budget. Work through these three layers in order.

Manual checks that cost nothing

Search your own branded terms on a schedule, and search them the way a violator expects you not to:

1. Build the term list: your brand, its common misspellings, and the modifier set: “brand coupon”, “brand discount”, “brand promo code”, “brand review”, “brand login”.
2. Search from where you aren’t. Violators geo-target away from a company’s home city and daypart around office hours. Use a VPN to check 2 or 3 major markets, and check evenings and weekends, not Tuesday at 10am from your desk.
3. Use incognito and a phone. Fresh sessions, desktop and mobile, since ads can be device-targeted.
4. Capture before you click: screenshot the full results page with the date visible, then click through and save the final URL. An affiliate parameter on the destination (?via=, ?ref=, or a redirect through a tracking domain) is your attribution evidence, ready to line up against the per-affiliate click records in your affiliate tracking platform.

Ad transparency libraries

The Google Ads Transparency Center lets anyone look up an advertiser and browse the ads they’re running, which turns a one-off sighting into a view of the whole campaign; it’s a great tool for this. Identify the advertiser behind a suspect ad, then check what else they run against your name. Meta’s Ad Library is the equivalent for Facebook and Instagram, useful when an affiliate runs paid social against your brand instead of paid search.

In both cases, you’re after two things: the display URL and the final URL. A display URL that imitates your domain, or a final URL landing on your site with an affiliate parameter attached, is the core of a violation report.

Monitoring tools, briefly and neutrally

If your program is big enough that weekly manual checks stop scaling (many geos, many dayparts, hundreds of affiliates), paid monitoring earns its keep. The established options, without a sales pitch:

All of them automate the geo- and daypart-rotation you were doing by hand, and they capture timestamped evidence. Start manual, and buy a tool when the manual routine finds its second or third violator; that’s your signal the problem is big enough to fund the fix.

The affiliate brand bidding policy template (copy and paste)

You can’t enforce a rule you never wrote down. The clause lives in your affiliate terms, and it needs to be specific enough that a violation is a matter of fact, not interpretation. Here’s a clause block you can copy into your agreement today; replace “Acme” with your brand and have a lawyer adapt it to your jurisdiction.

Paid Search and Brand Bidding Policy

1. Affiliates may not bid on, purchase, or otherwise target the trademark
   "Acme", the brand name Acme, or any of the Company's product names as
   search advertising keywords on any search engine or advertising platform.

2. The prohibition in clause 1 extends to misspellings, variations, and
   spacing or punctuation variants of the trademarks (for example "Acmee",
   "Akme", "Acme app").

3. Affiliates may not bid on trademark-plus-modifier terms, including but
   not limited to "Acme coupon", "Acme discount", "Acme promo code",
   "Acme review", "Acme pricing", "Acme login", and "Acme alternative".

4. Affiliates may not use the trademarks in paid ad titles, descriptions,
   display URLs, or in any manner that implies the ad is placed by or
   affiliated with the Company.

5. Paid ads may not link to the Company's website, whether directly or
   through a redirect. Paid traffic must land on the affiliate's own
   website or content.

6. Affiliates running broad or phrase match search campaigns in any
   category must add the trademarks in clauses 1 and 2 as negative
   keywords.

7. Exceptions require the Company's prior written approval, are limited
   to the specific terms named in that approval, and may be revoked with
   14 days' notice.

8. Commissions attributable to traffic acquired in violation of this
   policy are forfeit and may be reversed or withheld, whether or not the
   underlying sales are otherwise valid. Repeat or willful violation is
   grounds for termination from the program.

Why each clause is there, one line apiece:

• Clause 1 is the core ban; the platform-agnostic wording (“bid on, purchase, or target”) closes the “it was Bing, not Google” defense.
• Clause 2 exists because misspellings are the oldest workaround in the book; Amazon’s policy (below) treats them as equivalent.
• Clause 3 covers TM+ bidding, adding a word to dodge exact-match rules while harvesting the same intent.
• Clause 4 handles ad copy and display URLs, the one place Google will also act on complaint; you shouldn’t need Google’s queue.
• Clause 5 kills direct linking, how an intercepted click reaches your checkout with the affiliate cookie freshly set and no content in between.
• Clause 6 is the good-faith requirement: broad match can serve a generic ad against your brand accidentally, and negatives are the fix.
• Clause 7 keeps the door open for legitimate partners without weakening the default.
• Clause 8 is the one most programs forget, and it’s the entire enforcement mechanism. More on it below.

My one hard stance in this article: a brand bidding clause without a commission-forfeiture sentence is decorative. Clauses 1 through 7 tell the affiliate what not to do; clause 8 is the only line that changes their expected value, because it converts “we might get told to stop” into “we might do all this for nothing.”

Affiliate networks’ brand bidding policy fields vs your own terms

If your program runs through a network, you get a second lever, and it’s worth pulling: the major affiliate networks (CJ, Awin, Impact) each give you a program-terms surface where you can state a paid search and brand bidding policy that affiliates accept when they join, and network compliance teams will act on documented violations. Set the policy there and mirror the same clauses in your own terms, so the rule travels with the relationship, not the platform. A direct program has no network field to lean on, so the template above has to live in your affiliate agreement.

What HubSpot’s and Amazon’s clauses get right

Amazon Associates prohibits bidding on “amazon”, “kindle”, any Amazon Mark, and their variations or misspellings, and, critically, defines any such ad as a “Prohibited Paid Search Placement” whose referred purchases earn no commission at all; the bidding is banned and the proceeds are disqualified, per the Associates Program Policies. That second half is the enforcement hook, and it’s the part I admire most: Amazon understood that banning the act without forfeiting the earnings just prices in the risk.

HubSpot’s program policies state: “You will not purchase ads that direct to your site(s) or through an affiliate link that could be considered as competing with HubSpot’s own advertising, including, but not limited to, our branded keywords.” It also requires paid ads to land on the affiliate’s own site rather than hubspot.com. The scope is good; what the page doesn’t spell out is the consequence, which is exactly the gap clause 8 and the enforcement ladder below close in your own program.

Should you ever allow brand + modifier bidding?

Sometimes, yes, and always as a written exception rather than a soft default. There’s a real case for letting a proven content partner bid on “Acme review” or “Acme alternative”: that searcher is comparison shopping, and an honest review can win a buyer your own ad might not. If you grant it, scope it in writing: name the exact terms, require the ad to land on their review (clause 5 still applies), keep the core trademark and the transactional modifiers (“coupon”, “discount”, “login”) off the table, and reserve revocation. Your default stays enforceable while your best partners keep their flexibility, and that’s the balance you want.

The enforcement ladder: warn, withhold, terminate

Enforcement works when it’s boring: a known sequence, applied the same way every time, documented at each step. Here’s the ladder I recommend.

Step 0: capture evidence before anything else. Timestamped, full-page screenshots of the results page with the query visible; the ad’s display URL; the final landing URL including the affiliate parameter; and the click record in your tracking platform if the click reached your site. Do this before the warning email, because ads can be paused in minutes and your leverage is the paper trail.

Step 1: first offense gets a warning, not a hanging. Email the affiliate, cite the exact clause number, attach one screenshot, and give a 48-hour deadline to pause the campaign and confirm in writing; the copy-paste policy-violation warning email in my templates collection is written for exactly this rung. Most first offenses are sloppy broad match rather than malice, and a clean warning converts a violator into a compliant partner. I like that outcome: you keep the affiliate and lose the problem!

Step 2: repeat offense, withhold and reverse. Reverse the commissions earned during the violation window and hold pending payouts until the campaign is verifiably down. This step only exists if your policy contains clause 8; without a forfeiture clause you’re reduced to asking nicely while paying out.

Enforcement is only as strong as your attribution. Withholding a payout means being able to show which conversions came from the violating affiliate during the violation window, and defending that call if they dispute it. We built Rekomi’s per-affiliate tracking and conversion log to answer exactly that question: every conversion tied to the affiliate whose link or coupon produced it, with timestamps you can lay directly alongside your screenshots. If your current setup can’t produce that list, fix the attribution before you need the ladder; plans start at $19/mo.

Step 3: terminate and blocklist. A second repeat, or any willful evasion (new ad accounts, cloaked display URLs, geo-targeting away from your office), ends the relationship. Terminate under your terms, forfeit the open balance per clause 8, and record the affiliate’s details so a re-application under a new name gets caught. If the affiliate came through a network rather than signing up directly, file the evidence with the network’s compliance team too; networks track cross-program violators, and your report protects the next merchant.

Can you stop competitors bidding on branded terms?

Mostly no, and knowing that up front saves you months. Competitor bidding on brand keywords in Google Ads is allowed by Google’s own policy, so your options are narrower than with affiliates, who signed your agreement.

You’ve got three levers. A trademark complaint to Google works only against your trademark appearing in the competitor’s ad text, not against the keyword targeting itself. Outbidding usually favors you, and this is my favorite bit of auction math in the whole topic: your ad’s relevance to your own name tends to make holding the top slot cheaper for you than challenging it is for them. A legal letter occasionally works on smaller competitors, but outcomes vary by jurisdiction and the ad’s specifics; treat it as a conversation with your lawyer, not a standard play. And yes, the door swings both ways: bidding on competitor brand names yourself is legal under the same Google policy. Whether it’s worth the CPC premium is a separate math problem, and usually a harder one than defending your own name.

Frequently asked questions

Is brand bidding illegal?

Generally no. Bidding on a brand name as a keyword is legal in most jurisdictions, and Google’s policy permits it; the legal risk sits in the ad’s content, where using someone else’s trademark in a way that confuses buyers can cross into infringement. For your own affiliates, legality is beside the point: your agreement can prohibit it regardless, and that contract is your enforcement path.

What is brand bidding in affiliate marketing?

In affiliate marketing, brand bidding means an affiliate running paid search ads on the merchant’s own brand name so that bottom-funnel buyers click the affiliate’s ad, receive their tracking cookie, and convert as commissioned sales. The affiliate captures a commission on demand the merchant already created, which is why most serious programs prohibit it in their terms.

Should I bid on my own branded keywords?

It depends on whether the spend is incremental, and the honest answer is to test it: pause brand ads in a subset of geos and watch whether total branded conversions (paid plus organic) actually fall. One clear exception: if affiliates or competitors are actively bidding on your name, then definitely run your own brand ad; it’s cheap insurance for the top slot while you work the policy and enforcement side.

Can affiliates bid on my brand if my terms do not mention it?

Effectively yes. Google won’t restrict trademarks used as keywords, and an affiliate who never puts your name in their ad text is violating no platform rule. If your agreement is silent, your options shrink to persuasion and termination-at-will, and reversing already-earned commissions gets legally murky. But that’s also the easiest fix in this whole article: the clause belongs in your terms before you recruit affiliate number one, and adding it is a copy-paste job.

What is TM+ bidding?

TM+ (trademark plus) bidding targets your brand name plus a modifier: “brand coupon”, “brand discount”, “brand review”. It’s the standard workaround to a policy that only bans the exact trademark, and it often captures even hotter intent, since someone searching “Acme coupon” is minutes from checkout. A complete policy bans TM+ terms by default and handles legitimate cases, like review terms for trusted content partners, through written exceptions.

How do I find out who is bidding on my brand name?

Search your branded terms on a schedule from multiple locations (VPN) and at off-hours, since violators geo-target and daypart around your habits; then identify the advertiser in the Google Ads Transparency Center and inspect the ad’s final URL for affiliate parameters. If manual checks keep finding violators, graduate to a monitoring tool.

Bake the policy in before you need it

Do this today: open your affiliate terms and search for the word “keyword”. If it’s not there, adapt the eight clauses above, publish the update, and email existing affiliates a two-line notice with the effective date. Then put a 20-minute weekly slot on your calendar for the manual detection routine, and that’s the whole system! A written rule, a repeatable check, and a ladder you follow without drama. Everyone sleeps better, including your genuine affiliates, who now know the program they’re building on is defended.

Setting up a program from scratch? Even better: sequence it right and you never need the retrofit email; my guide to starting a SaaS affiliate program covers where terms fit in the launch order. On Rekomi, affiliates join under your campaign terms, so the clause governs the relationship from day one, and the tracking layer can already answer the only enforcement question that matters: which affiliate did this conversion come from?
