Enter a competitor’s domain, or a single page, and Google returns the keywords it associates with that content, each with its average monthly searches, competition and cost per click. Free, no sign-up, no daily limit.
What this tool tells you, and what it does not
Read this before you read the table, because it decides how you should use the numbers.
What you get: the keyword ideas Google Ads associates with that website or page, with real search volume, competition and CPC. In other words, the topics and terms that site is about, and how much demand each one has.
What you do not get: the keywords that site currently ranks for, its positions, or its traffic. That is a different kind of data and it comes from rank-tracking tools, not from Google Ads. Any free tool promising you a competitor’s exact ranking keywords is either guessing or charging you later.
Used for what it actually is, this is one of the fastest ways to map a competitor’s topics: you see the demand behind their subject matter without reading a hundred pages of their site.
See your competitors’ keywords
Start with the domain. Type competitor.com, leave the choice on The whole website, and you get the broad picture: the themes the site covers and which of them carry real search demand. It is the quickest way to answer “what is this business actually about, and is anyone searching for it?”
Then sort the table by volume and look for two things. First, big terms they cover and you do not, those are gaps in your own site. Second, low-competition terms with decent volume, which are usually where a smaller site can win first.
Check the keywords for a single page
Switch to Only this page and paste a full address, such as competitor.com/blog/best-running-shoes. Now the ideas come from that one page instead of the whole domain.
This is the mode to use when a specific article of theirs outranks yours. You see the terms Google reads that page as covering, which tells you what your own version is missing. It also works on your own pages: run a page of yours, and if the ideas that come back are not the topic you intended, the page is not as clear as you thought.
Extract keywords from any website
The address does not have to belong to a competitor. Useful things to run through it:
- A supplier or manufacturer site: to learn the product vocabulary your customers actually use.
- A marketplace category page: for buying-intent phrasing.
- A site in another country: set the matching location and language first, and the ideas come back in that market’s terms.
- Your own homepage: a blunt but honest check on whether Google understands what you sell.
How to read the results
- Avg. monthly searches: demand over the last 12 months. Google rounds these, so treat them as size bands.
- Competition: how hard advertisers compete for the term. It is an advertising signal, not an SEO difficulty score, but high competition usually means money is involved.
- Avg. CPC and bid range: what a click is worth to advertisers. High CPC on a modest-volume keyword is a strong hint the traffic converts.
Use the minimum-volume box to hide the long tail of near-zero rows, filter for a sub-topic you care about, then export the shortlist to CSV and mark which of your pages should cover each keyword.
Why a site sometimes returns nothing
An empty table is not a bug. It usually means one of these:
- The site is new, very small, or has little text Google can read.
- The page is behind a login, a paywall or blocked from crawling.
- The topic is so narrow that Google has no keyword data for it.
- The location and language you picked do not match the site’s own market.
If a single page returns nothing, try the domain on its own. If a domain returns nothing, try a large content page such as their blog index.
Where the data comes from
Google Ads, through the official API, the same source behind Keyword Planner. Google reads the address you enter and answers with associated keyword ideas and their metrics. Nothing is scraped from the site, and no page content is stored here.
