Free competitor keyword analysis
Find the keywords a competitor ranks for and you don't
Type your domain and one competitor's. In about 20 seconds you get up to 20 keywords where their page is in Google's top 20 and yours isn't, with monthly US searches, keyword difficulty, and search intent for each.
Competitor keyword analysis is the practice of listing the search terms a rival site ranks for and comparing them with your own, so you can see the topics they cover and you don't. Each missing keyword with real search volume is a page you could write.
What to do with the list
Say you run a backpacking food blog and the check against a bigger rival returns no cook backpacking meals at 2,400 searches a month, with their page in position 3. You have a cold-soak post but nothing on no-cook meals. That's a post to write. The same list might also include their gear reviews, which you'd skip, because your readers come to you for recipes.
Sort by difficulty before you sort by volume. A keyword at KD 15 with 500 searches is a post a small site can win this quarter; one at KD 70 with 5,000 is a post the big sites own. Open their ranking page before you start, and note what it covers that yours wouldn't. If you want the list each week with a plan for taking the top keyword and your own rank changes, the free plan sends it.
Before you commit to writing, check whether Google already answers the keyword itself: the AI Overview tracker flags which of these keywords already show one, since those send fewer clicks even at position one.
About the data
Where do the keywords come from?
From an index of Google results in the United States. The tool looks for keywords where the competitor has a page in the top 20 and your domain has none, and sorts them by monthly searches. Keyword difficulty is on a scale from 0 to 100, and intent is what most searchers want from the query: information, a comparison, a purchase, or a specific site.
Why only 20 keywords?
Each check costs money to run, and the tool is free. Twenty is enough to see whether a competitor is worth watching. The paid plans keep tracking the gap for you.
Why does it say I've used my checks?
Each visitor gets 5 checks a day, and the tool has a daily budget across everyone. The same pair of domains checked again within 7 days comes from the saved result and doesn't use a check.
Does it work outside the United States?
The free tool checks US results only. In the app, a site is tracked in one or more markets, each a country, a language, and a desktop or mobile device. Daily rank checks work in 211 countries. Competitor keywords, search volumes, and difficulty are available in 92 of them, and the app says so when you pick a country outside that list.
