Free SEO Tools
Free SEO tools that answer one question each, with no signup and no email gate. Seven of them: four technical checkers that test whether a page can be found and indexed, two planning tools, and one first-party data set.
Each is a single screen of the engine we run for clients. That is the honest reason they are free — we were building them anyway, and a tool that shows its working is a better argument than a brochure.
That was one check on one page. The free audit runs the full set across your site and ranks what to fix first. That is the difference between a single free SEO audit tool and a pass over every page you own.
Technical checkers
Google index checker — tests whether Google is permitted to index a URL and names the exact thing standing in the way when it is not. It runs the four gates a page has to pass: does it return a page, is Googlebot allowed to fetch it, does anything on the page say noindex, and where does the canonical point. Start here when one page will not appear.
Crawlability checker — runs the four checks a crawler runs, in the order a crawler runs them: can the URL be discovered, is Googlebot allowed to request it, does the server answer cleanly, and does it resolve where it claims to. Indexability problems are usually crawl problems one step upstream, so this is the natural second run.
Orphan page checker — finds pages nothing links to. It does the thing a crawler cannot do alone: reads your XML sitemap, crawls your site from the homepage following internal links, and subtracts. Anything in the sitemap that no page links to comes back as an orphan. It also says which orphans do not need fixing.
SEO friendly URL checker — tests an address against twelve rules and, for each, tells you whether the rule comes from Google's own documentation or from practitioner consensus. Most URL tools present both as the same kind of fact. They are not, and the difference changes what is worth acting on.
Planning tools
Striking distance keyword tool — paste a Search Console export and it surfaces the terms sitting just outside the positions that earn clicks, where a small on-page move is worth more than new content. This is one screen of the prioritisation module.
The Coverage Map — a topical map template that measures coverage rather than listing ideas. Every downloadable map answers "what should I write next"; this one also answers "what do I already cover" and "am I finished". Free spreadsheet, Excel and Sheets, no form in front of it.
First-party data
AI SEO statistics — figures measured on our own engine running against this site, with the method attached to each one. Most statistics roundups recycle the same vendor surveys with no method at all. These are first-party measurements from tracked URLs, including how far published search volumes drifted from what we measured.
What a free SEO checker can and cannot tell you
These tools test conditions, not performance. They can tell you a page is blocked, misrouted, unreachable or unlinked. They cannot tell you whether Google has actually indexed it, where it ranks, or why last month's traffic moved — none of that is visible from outside your Search Console.
That distinction matters because most "site health" scores blur it, and a green score on an eligibility check gets read as evidence of performance it never measured. Each tool states its own limits on its own page, deliberately.
When you want the full read
A checker looks at one page and one condition. A programme looks at every page, the keyword each one can realistically own, and how they link to each other. If you want that read on your own site, the free site audit is where it starts — your first telemetry read, not a discount.
The tools above are single screens of a ten-module engine. See what the other modules do.
Free SEO tool FAQs
Are these really free?
Yes — no signup, no email gate, no trial timer. They run in the browser and nothing is stored against you.
What can a free SEO checker not tell you?
Whether a page is indexed, how it ranks, or why traffic moved. They diagnose eligibility, not performance.
Which one should I run first?
For a single missing page: index checker, then crawlability checker, in that order. For a site that feels patchy: the orphan page checker.
Do they work on any website?
The technical checkers work on any public URL on any platform. The striking distance tool needs a Search Console export. The Coverage Map is a spreadsheet.
Every free tool on this site
Seven tools, no signup. Each answers one question and says what it cannot tell you.
