The SEO crawler that won't stay quiet about your site's problems.
Paste the pages that should link to you. Each one is fetched and read: the link, its anchor text, whether it is followed, and whether the page it sits on counts at all.
A link from another domain to yours. Links inside your own site are internal links; a backlink is one that comes from outside.
Google's original idea was that a link is a vote, and that the vote counts in proportion to the authority of whoever casts it. It is still one of the signals most strongly correlated with ranking, and it does two other things besides: Google finds new pages by following links, and real people arrive through them.
Give it your domain and the list of pages that are supposed to link to you. It fetches each one and answers, per page:
www host does not come out as a lost link.rel carrying nofollow, ugc or sponsored cancels it. All three, not just the first: looking only for nofollow reports comment links and paid links as if they were editorial.alt when the link is an image, which is the only thing a search engine reads there.noindex, or carrying a page level nofollow that unfollows every anchor on it at once, is a link worth nothing. Neither is visible by looking at the page.It does not discover links. Knowing who links to you requires an index of the whole web, and that index is literally the product of the handful of companies that sell it. What can be done without one is what this page does: confirm the links you already know about. And that is the half that rots quietly — a redesign drops the link, a plugin adds rel="ugc" to everything outbound, a migration leaves the page on noindex. Nothing turns red in any dashboard when it happens.
How many pages can I check at once? Ten. Each one is a fetch of somebody else's site, so the tool is generous enough for a real link list and not generous enough to be used as anything else.
Is a nofollow link worthless? It passes no authority, but it still brings visitors and still helps you get found. A link profile with no nofollow links in it is also not a natural one.
