Free SEO tools
Seven free SEO tools, no signup. They run the same checks we run on every domain before it reaches the directory.
Checking a domain in three steps
1. Is the name expired, and what was it?
The expired domain checker asks the registry over RDAP for the status codes and expiry date, runs a live DNS lookup, and shows the site history from archived snapshots. Expired is not the same as available. The result says which window of the drop timeline the name is in.
2. Does anything still point at it?
The backlink checker lists the linking domains we hold for a domain, with a source page and anchor text from each and whether the link is dofollow. The domain authority checker turns the same web crawl into one 0 to 100 score with the ranks behind it. Both run on an open web crawl and our own crawl, not on a paid link index.
3. Would a search engine or an AI answer trust it?
The agent citability checker scores a domain on links from a curated list of reference, government, academic and editorial sources. The traffic, keyword difficulty and technology tools add context from a third-party keyword index and say so on the page.
Frequently asked questions
Are these SEO tools free?
Yes. None of the seven tools needs an account, a card or a usage cap beyond a per-visitor rate limit. Enter a domain or a keyword and read the result.
Where does the data come from?
Four of them use no paid data: an open web crawl and our own crawl of links, which we hold, plus archived captures and live registry and DNS lookups. The traffic, keyword difficulty and technology tools query a third-party index, and each page says so.
Which tool should I use to check a domain?
Domain authority checker if you want one number for a domain's link standing. Backlink checker if you want the links themselves. Expired domain checker if you want to know whether a name has lapsed and what it used to be. Run all three on the same domain before you value it.
Do you show Moz Domain Authority?
Domain Authority is Moz's score and only Moz can report it. Our checker reports Revised Authority, a 0 to 100 score computed from our open web crawl. It measures the same kind of thing on a different scale.
Looking for a domain, not a diagnosis?
The directory lists expired domains with backlinks. Every listing shows referring domains, site history and authority up front, and the name is revealed on any plan.
