What it is.
Semrush keeps a set of checkers outside the paywall, with no sign-up required. You can audit a site's SEO health, estimate a competitor's traffic, pull keyword ideas or check AI visibility, one question at a time.
Treat them as spot checks. Each one answers a single question about a single domain, so tracking anything over time is what the paid plans are for.
What you get.
- An SEO health check on any domain, with the issues named.
- A traffic estimate for a competitor, without owning their site.
- Keyword ideas from the Keyword Tool, free to run.
- An AI Visibility Checker, for how assistants describe a brand.
How to set it up.
Open the free tools page and pick the checker that matches the question you came with.
Run the SEO Checker on your own domain first, so you have a baseline to compare against.
Run the traffic checker on two competitors, since one number on its own tells you little.
Write the findings down as you go, because nothing is saved between visits without an account.
Move to Search Console or a crawler for anything you need to watch over time.
