Free tools

No signup, no email wall, no truncated result upsold to a subscription. Each of these answers one question, deterministically, and shows its working.

Free website auditIs my page ready for search and for assistants?Fourteen deterministic checks across SEO, AEO and GEO in one scan: readable without JavaScript, AI crawlers allowed, structured data, llms.txt, title, canonical, sitemap, Open Graph.

AI crawler checkCan ChatGPT read my site at all?Fetches your page as OAI-SearchBot, ClaudeBot and PerplexityBot — no JavaScript — and shows the text they receive plus the real status each one gets.

Dofollow link checkerIs this backlink actually worth anything?Lists every outbound link on a page with its rel attribute, and whether it passes ranking signal or is suppressed by nofollow, sponsored or ugc.

Startup directories, dofollow-verifiedWhere should I submit, and does it pass signal?Places to list a product, each with its link type checked rather than copied from another list — and the date it was last looked at.

Domain Rating checkerWhat's my Domain Rating, and what would actually raise it?Free lookup straight from Ahrefs' own public endpoint, plus what the number is actually built from and which of our tracked directories move it.

Guides

The tools answer one question each. These write up the rest of it — what to do about the answer, and which of the usual advice has evidence behind it.

How to make your site readable by AI assistantsPairs with the AI crawler checkThe three failures that decide it — zero-JavaScript crawlers, the robots.txt rule that quietly deletes you from ChatGPT's citations, and CDN bot blocking you cannot see from your own browser. With what is measurable separated from what is folklore.

How to earn dofollow backlinks as a new productPairs with the Dofollow link checkerWhat a followed link actually is, what happened when we tried to verify 51 startup directories instead of copying a listicle, and the places a product with no audience can realistically earn links.

What a launch directory actually reads off your pagePairs with the AI crawler checkThe exact order a scraper reads your tags in — Open Graph first, then the title and meta description, then whatever text it finds — why listings end up saying “Home” next to an empty card, and the ten-minute fix that works on every directory at once.

What actually happens on launch dayPairs with the Dofollow link checkerLaunch traffic converts at around a quarter of a percent and most spikes flatten within the week, so a launch is worth doing for the page and the link rather than the graph. How to order launch week around directory queue lengths, and what to check afterwards.

Why these three and not an “AI visibility score”

Because a score would be made up. No published scoring method has been validated against whether a page actually gets cited, and asking a model whether it knows your product returns a different answer on repeat runs — 9% to 28% of decisions flip even at temperature zero.

Every tool here checks something mechanical instead: what a server returns, what text is in the HTML, what a rel attribute says. Same input, same answer, every time — and you can verify all of it yourself with curl.

LetsLaunch makes money when people list products here, so treat any claim we make about listings with the scepticism it deserves. These tools don’t require you to.
