How to See What Your Competitors Are Advertising on Google
Google publishes every ad from every verified advertiser in a public database. Most small advertisers have never heard of it. Here is how to read it, what it will not tell you, and what to do with what you find.

You can look up every Google ad a competitor is running right now, for free, in about two minutes, without installing anything or handing over an email address. The database is public and Google runs it themselves. Most small advertisers have never been told it exists.
This guide covers the free official route, the one paid signal that is genuinely worth knowing, what neither of them will tell you, and the mistake people make with what they find.
First, this is not sneaky
People search for this using the word “spy”, so let us deal with that. Since 2023 Google has run the Ads Transparency Center, a searchable archive of the ads served by verified advertisers. It exists because regulators required advertising to be auditable, not as a favour to marketers. Anyone can use it, including your competitors on you.
So nothing here involves a loophole or a grey-market tool. It is a Google product, published deliberately, that most people have simply never opened.
The two-minute version
- Open the Google Ads Transparency Center.
- Search for the competitor by name, or paste their domain.
- Set the region to the country you actually sell in. The default is worldwide, and an advertiser can run completely different ads in different markets.
- Filter by format if you only care about one: text ads, image ads, or video.
- Click any ad to see the exact creative, and the dates it ran between.
Do this for five competitors, not one
A single competitor tells you what one business believes. Five tell you what the market has settled on, and the outlier in the group is usually the interesting one. It takes ten minutes.
What you can see, and what you cannot
This is where most articles on the subject quietly overpromise, so here it is straight.
You cannot see
What they spend
You cannot see
Which keywords they bid on
You cannot see
Their click-through rate
You cannot see
Whether any of it is profitable
You cannot see
Their landing page conversion rate
| You can see | You cannot see |
|---|---|
| Every ad creative currently running | What they spend |
| The date range each ad ran | Which keywords they bid on |
| Which formats they use | Their click-through rate |
| Which countries they target | Whether any of it is profitable |
| How long an ad has survived | Their landing page conversion rate |
The trap in that second column
You are seeing what a competitor does, not what works. A business can run a bad ad for a year because nobody is watching the account. Treat what you find as a list of hypotheses, not a list of proven winners.
What to actually look for
Scrolling through competitor ads feels productive and usually is not. Four things are worth writing down.
1. The offer, not the wording
Free consultation. Same-day appointment. No call-out fee. Financing available. The offer is the part that changes results. Clever phrasing rarely is.
2. The ad that has run longest
The transparency centre shows date ranges. An ad that has been live for eight months in a competent account is the closest thing to evidence you will get here, because somebody kept paying for it. An ad that appeared last week is a test.
3. Where the click lands
Follow the ad to the page. A serious advertiser sends a “dental implants” ad to a page about dental implants. Many send everything to the homepage. If your competitors are doing the second thing, that is an opening rather than a benchmark.
4. Who is missing
If the biggest name in your area runs nothing at all, that is information too. Either they do not need paid search, or they have not got round to it. Both are worth knowing before you set a budget.
The other half: Auction Insights
The transparency centre tells you what ads exist. It does not tell you who you are actually up against, because the advertiser you worry about may not be bidding on your keywords at all.
That answer lives inside your own Google Ads account, in the Auction Insights report. It lists the domains appearing in the same auctions as you, how often they show up, and how often they sit above you. It requires enough data to be meaningful, so it is useless in week one and valuable by month two.
Use them together
Auction Insights names the competitors who genuinely compete with you. The Transparency Center then shows you what those specific advertisers are saying. Doing it in that order saves you from studying a company you never meet in an auction.
Can you bid on a competitor's brand name?
Using a competitor's name as a keyword is permitted by Google. Putting their trademarked name in your ad text is not, and that distinction is where accounts get into trouble. It is common practice across most industries.
Which is also the argument for bidding on your own name. If competitors can appear above you when somebody searches for your business specifically, letting that happen unopposed is an odd thing to allow. Brand terms are usually the cheapest clicks in the account anyway.
What to do with what you found
Here is the part that decides whether the last twenty minutes were worth anything. Competitor research produces a list of ideas, and a list of ideas changes nothing until it becomes a change in your account.
- Pick the one offer you saw repeatedly and do not currently make. Test it as a headline.
- If several competitors send traffic to a dedicated page and you send it to your homepage, fix that before touching a single bid.
- Write down the advertisers from Auction Insights who outrank you consistently, then check whether they are outranking you everywhere or only on a handful of terms. Usually it is the second.
- Ignore everything else you wrote down. A list of thirty observations gets acted on at the same rate as a list of zero.
One thing competitor research cannot do
It only ever looks outward. It will never tell you that a search term in your own account spent $340 last month and produced nothing, and in most small accounts that is the larger, easier problem. Both halves are worth an afternoon.
