About NoAISEO
We sell link data to people who care who wrote the page. The tool is small, the claims are smaller, and this page says where the edges are.

What we do
Link data by API
Backlinks, referring domains, anchors, top pages and a 0–100 Domain Rating for any domain, as JSON.
A free explorer
Domain, overview, stats and suggest need no key, so you can look before you sign in.
Our own index
181,132,097 domains and about 798.5 billion backlinks, from our own crawler, refreshed roughly monthly.
Why this site leans toward hand-made work
Writers who build pages one at a time have a different problem from those who publish by the thousand. They need to know whether anybody noticed, and who.
Our stance is simple. Links are a record of other sites' choices. They are not a verdict on how a page was written, and we say so wherever the question comes up, for example in our troubleshooting table.
We write about E-E-A-T, authorship and detectors because buyers of link data ask us about them. Insider knowledge of Google? None. When something is documented we give the date, and when it is a guess we label it.
How we handle claims
Every number about the product on this site comes from one internal fact sheet, and every number about Google comes from something Google said in public, with a month attached. Nothing else gets a figure.
That rule is dull. It also keeps us out of trouble, because authorship and E-E-A-T attract confident guesses, and we would rather be the dull voice. Where we are unsure, the text says unsure.
You will not find testimonials here. We have none we could verify, so we publish none. If that changes, the quotes will carry names you can check.
Compare us with Ahrefs, Semrush, Moz or Majestic if you like. Their suites are larger. The fair question is whether you need all of it: for link data at a low per-call price, a small index may be enough, while for rank tracking it is not.
Where the numbers come from
Each figure on this site traces to one of these sources, and none was rounded up to look better.
Our link index
A web link graph of 181,132,097 domains and 2,774,625,913 domain-to-domain links. It is one month stale at worst, and sometimes more. Say so out loud.
Our Domain Rating
A formula we publish: round(100 · log(ref_domains+1) / log(2·10^7)). It rewards breadth of referring domains and ignores everything else, so a small famous site can score low.
Google's public statements
February 2023 guidance on AI content, the March 2024 spam policies and the December 2022 addition of Experience. We cite the month, and we avoid anything not stated in public.
Our prices
Prepaid credit at $0.0001 each, so from $0.10 per 1,000 calls, with the first $100 free. Ahrefs sells API units inside subscriptions from $129 a month for 200,000 units.
We do not detect machine-written text, grade authorship, sell links or promise rankings. Ahrefs and Semrush are the fuller products for keywords, rank tracking and daily-fresh crawling.
Who is behind it
The site is run by the NoAISEO research team. We publish no personal profiles and no customer stories, because we have not collected any we could verify.
Pricing is prepaid: 1 credit costs $0.0001, with no subscription and no monthly minimum, and new accounts receive $100 of credit. Questions go through the account page, and you can read the privacy notes and terms of use.
