Which one is for you
Pick SEOquake if
- Fits if you check a rival's traffic and backlink figures while you browse
- Works for reading Semrush figures for every result on a Google search page
Look elsewhere if
- Watch out: the traffic and backlink figures are Semrush estimates, not data from your own analytics
- Skip it if you use Firefox, where the version is 3.9.9 from December 2022 against 4.3.0 on Chrome
- Tight if you won't make a Semrush account, as Authority Score, referring domains and Traffic Analytics need one
- Not for you if you want the interface in a language other than English

Look elsewhere if

- Tight if you want to try it properly, as the free trial lasts 3 days
- Watch out: its own pricing page couldn't be read, so usage limits and any team plans are unconfirmed
- Skip it if you don't pay for Ahrefs, since the Ahrefs metrics need your own account
- Not for you if you're not on Chrome, as no Firefox version was found
How we grade them

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
