Competitor bidding on my brand name: what to do

You searched your own brand and a rival's ad sat above your result. The bad news: in most cases that's allowed, and Google will not stop it for you. The good news: there's a clear playbook. This guide covers how to confirm exactly who is bidding on your name (harder than it sounds: the keyword itself is invisible), where UK trade mark law actually draws the line, the complaint route that does work, and how to make brand bidding too expensive for your rival to keep doing.

Can competitors bid on my brand name?

Yes. Google's trademark policy is explicit: it does not restrict trade marks being used as keywords. Anyone can bid on "your brand name" and show an ad when people search for you. What Google does restrict — and only when the trade mark owner complains — is use of the mark in the ad text itself in a way that's confusing or misleading about who's behind the ad.

So the two halves of the problem get treated completely differently:

This is why most brand-bidding ads never mention your name. The rival captures your searcher with a generic headline ("Compare Top Providers", "Better Than the Big Names"), and the keyword that triggered it stays hidden. Which brings us to the real difficulty: detection.

How to find out who's bidding on your brand name

There is no report anywhere that says "these companies bid on your trade mark". The keyword lives inside the rival's Google Ads account, and no public tool exposes it — not even Google's own Ads Transparency Center, which shows creatives but has no keyword search at all. You have to triangulate from three angles.

1. Search your own brand like a customer would

Obvious, but most people do it wrong — once, from the office, on desktop. Ad serving varies by device, location, time of day and auction pressure, so a single clean search proves nothing. Do it properly:

• Incognito/private window, so your history doesn't suppress or reshape the ads.
• Mobile and desktop separately: mobile shows fewer ads, so rivals concentrate budget there.
• Several times across the week, including evenings and weekends. Many brand bidders use ad scheduling precisely so the target's marketing team never sees them during office hours.
• Misspellings and "brand + product" variants ("yourbrand discount code", "yourbrand reviews"). These convert well and attract bidders who stay off the exact-match term.

Screenshot everything you find, with the search term and date visible. You'll want this evidence later, whichever route you take.

2. Pull the Auction Insights report

If you run Google Ads on your own brand terms (you should; more on that below), the Auction Insights report is the closest thing to an official answer. Segment it to your brand campaign and it lists the domains competing in the same auctions, with impression share, overlap rate, outranking share, top-of-page rate and position-above rate.

Three caveats people miss:

• It only covers auctions you entered. No brand campaign, no report. If the rival bids on "yourbrand reviews" and you don't, they won't appear.
• It shows domains, not intent. A comparison site or affiliate in your auction is a different problem (and a different conversation) from a direct rival.
• It needs minimum activity thresholds before Google will populate it, so thin brand campaigns can show nothing even while bidding is happening.

3. Identify the advertiser in the Transparency Center

Once you've caught an ad in the wild, the Ads Transparency Center tells you who's really behind it: the verified legal name, location and — since Google's May 2025 policy update — the payer name, which exposes agency-run and white-label arrangements. You can then browse the rest of that advertiser's live text ads and see whether the creative you caught is part of a deliberate conquesting campaign or a one-off broad-match accident.

Know the tool's limits before you treat its list as complete: there's no keyword search, no alerts, no change history, and for big advertisers a hard retrieval cap means you'll only ever see a fraction of their live text ads. We documented all of this first-hand in our guides to what the Transparency Center hides and why it won't show all of a brand's ads.

Is brand bidding legal in the UK?

Mostly yes — with one important line you can use. The defining UK case is Interflora v Marks & Spencer: M&S bid on "Interflora" to advertise its own flower delivery, and after a five-year fight the High Court found infringement in 2013, reasoning that a significant proportion of searchers would assume M&S was part of the Interflora network. The Court of Appeal then overturned that finding in 2014 and ordered a retrial, clarifying the test that still governs today: keyword bidding infringes only where the ad suggests an economic link with the trade mark owner, or is so vague that a reasonably well-informed user can't tell there isn't one.

In practice:

• Clean conquesting is lawful. A rival bidding on your name with an ad that's clearly their own brand, making no claim of connection, is very unlikely to infringe.
• Confusion is actionable. Your name in their headline, copy implying partnership or "official" status, or a landing page dressed to look like yours moves them into infringement territory — and also into the scope of a Google trademark complaint.
• Interflora was unusually exposed because it's a network of member florists, so "M&S might be a member" was a plausible consumer belief. If your brand has resellers, franchisees or partners, the same ambiguity cuts in your favour.

None of this is legal advice. If a rival's ads are genuinely confusing customers — support tickets, reviews mentioning the wrong company, misdirected complaints — speak to a trade mark solicitor before doing anything public. Evidence of real-world confusion is exactly what these cases turn on.

How to stop competitors bidding on your brand

File a Google trademark complaint — for ad text, not keywords

If your name appears in the rival's ad copy and you hold a registered trade mark, use the Google Ads trademark complaint process. Google reviews complaints against specific advertisers in the countries where you've demonstrated trade mark rights, and can block your mark from that advertiser's ad text. Be precise: you'll identify the offending advertiser by URL, which is where your screenshots and the Transparency Center's verified-advertiser details earn their keep. What this route will never do is stop the keyword bidding itself — no complaint form on earth removes you from their keyword list.

Ask them to stop

Unglamorous, frequently effective. A short, civil note to their marketing lead — "we've noticed you're bidding on our brand terms; we don't bid on yours and would rather keep it that way" — ends a surprising amount of brand bidding, especially between brands of similar size where retaliation is credible. Often the bidding is an agency's broad-match leftover nobody senior ever approved, and it dies the day someone internal sees the screenshot. Mutual non-aggression on brand terms is common precisely because brand-term CPCs are pure waste for both sides once a war starts.

Make it unprofitable

If they won't stop, raise their cost of staying:

1. Run your own brand campaign. Your Quality Score on your own name should dwarf theirs, so you pay pennies while forcing their CPC up. This is also what unlocks Auction Insights monitoring.
2. Dominate the page. Sitelinks, callouts and other assets make your ad physically larger, shrinking the click-through their ad can steal.
3. Tighten your organic result so that even when their ad sits top, your ad-plus-organic block owns the rest of the screen.

Most brand bidders are testing whether it quietly converts. Make the maths ugly and they reallocate.

Should you bid on their brand name back?

Sometimes — go in with open eyes. Retaliatory bidding usually means high CPCs, low Quality Scores and conversion rates a fraction of your own brand terms, so treat it as a pressure tactic or a genuine conquesting test, not a growth channel. And remember the fight isn't only fought in keywords: rivals can name you openly in creative where comparative advertising rules allow it. In our tracking this October, carwow is running live Meta ads built around a head-to-head fee table: "Carwow Max Fees £0, Motorway Max Fees £99, WeBuyAnyCar Max Fees £124", naming both rivals on the face of the ad. Lawful comparative advertising done confidently, and exactly the kind of thing you want to know about the day it launches, not the quarter after.

Keep watching — this is a monitoring problem

Brand bidding is rarely a one-off event. It gets switched on for a rival's sale week, scheduled outside your office hours, tested on misspellings, dropped when you complain and resumed a month later. One clean search result today tells you about today.

That's the half of the problem we built AdRival for. We capture the ads UK brands run across Google, Meta, TikTok and LinkedIn — 164 brands and more than 50,000 AI-qualified creatives at the time of writing — and flag what's new, what's on promotion and who a creative actually targets, week on week. If a competitor starts conquesting your category or naming you in a comparison table, it shows up in the next capture rather than in next quarter's revenue dip. Browse the live brand libraries to see the data, or start with a rival you already suspect.
