Free SEO tools
Six 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. It runs 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 checker adds real-visitor rank history, the technology lookup reads a site’s homepage, and the keyword difficulty tool adds context from a third-party keyword index and says so on the page.
Frequently asked questions
Are these SEO tools free?
Yes. None of the six 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?
Five of them use no paid data: our own web crawl of links, monthly top-site rank lists for the traffic checker, archived captures, live registry and DNS lookups, and a live read of a site's homepage for the technology lookup. Only the keyword difficulty tool queries a third-party index, and its page says so.
Which tool should I use to check a domain?
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. Agent citability checker if you want to know how deeply the sources answer engines trust already reference it. Run all three on the same domain before you value it.
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.
