Confirm a specific backlink actually exists on a specific page.
This checks one specific page-to-page link, which is a fundamentally different (and honestly answerable) question from "who links to me across the whole web" — that requires a proprietary crawled link index no free, key-less API provides. See the FAQ below for why.
Backlink Checker answers one specific, verifiable question: does a particular page actually contain a link to your site, and if so, what does that link look like — its exact URL, its anchor text, and whether it carries a nofollow/sponsored/ugc attribute that affects how much SEO value it passes. This is the kind of check you run after securing a guest post, a directory listing, or a press mention, to confirm the link actually went live as promised.
Most tools marketed as "backlink checkers" claim to tell you every site linking to yours across the entire web. Doing that for real requires a continuously crawled, indexed database of a meaningful fraction of the internet — the kind of infrastructure that companies like Ahrefs, Semrush and Moz spend enormous ongoing resources building and maintain behind paid subscriptions. There is no free, key-less, CORS-accessible API that provides genuine whole-web backlink discovery, and we were not willing to fake that with placeholder data. What we built instead is a real, honestly-scoped tool: point-to-point link verification, which is something a browser genuinely can check live.
The tool fetches the source page's HTML through a CORS-enabled relay, parses every anchor tag on that page using the browser's own DOM parser, resolves relative links to full URLs, and filters for any that point to your target domain. Each match is shown with its exact destination URL, visible anchor text, and rel attribute value.
Confirming a paid guest post or sponsored placement actually includes the agreed link before you pay an invoice. Checking whether a mention of your brand in a news article was ever turned into an actual hyperlink. Auditing your own internal cross-linking between two pages you control. Verifying a link exchange or partnership listing is still live after a site redesign.
No — it checks one specific source page you provide against one target URL. Whole-web backlink discovery needs a crawled link index, which this free tool doesn't have access to.
It's a hint to search engines not to pass ranking credit through that link — common on user-generated content, comments, and paid placements, per search engine guidelines.
If the link is inserted by JavaScript after the page loads, this tool won't see it, since it reads the page's raw HTML rather than executing scripts on it.
The tool normalizes both with and without "www" as the same host, so either form of your domain will match correctly.
Setting up Google Search Console for your own domain is the closest free, legitimate option — it shows a sample of pages Google has found linking to you, sourced from Google's own crawl.
