Link checker
Enter the page that is said to link to you. The tool opens that page, finds the link to your site and tells you whether the link passes value. Use it after you are listed in a directory, mentioned in an article, or after a collaboration.
Also free: the Medical Visibility Checker for your own articles and the AI visibility test.
The link ledger is part of the full version, unlocked by the access code in the handbook. Get the book.
Site blocked the request? Paste the page source
Some sites (press release services, some directories) refuse automated requests. In that case you can open the page yourself and paste its source. Step by step:
- Open the page in your browser.
- Right-click an empty area of the page and choose “View Page Source”. If you prefer a shortcut: Ctrl + U on Windows and Linux, Option + Command + U on a Mac. (In Safari, first turn on Settings → Advanced → “Show features for web developers”.)
- On the source page, select everything with Ctrl + A (Command + A on a Mac) and copy it with Ctrl + C (Command + C on a Mac).
- Paste it into the box below and click the button.
The analysis still runs in your browser; the text you paste is not sent anywhere.
Link ledger
The links you have verified stay here. Links die quietly: a site is redesigned, an article is deleted, a directory closes, and nobody tells you. Once a month, click “Re-check all”; the tool looks at each link in turn and flags the ones whose status changed.
Bulk add: enter several addresses at once
Write one address per line (up to 40). The addresses are added to the ledger as “not checked”; then “Re-check all” checks them one by one. Your own domain is taken from the field above.
What the result means
Nothing on the link turns off value passing. HTML has no dofollow attribute; the word simply means that no blocking value is present. Search engines and AI systems may count this link as a signal of trust.
The site owner has asked that this link not pass value. Visitors still arrive, but no transfer of authority should be expected. Many directories work this way.
The link is declared as paid or sponsored. This is the correct markup: search engines ask that paid or sponsored links be marked sponsored or nofollow, so leaving a paid link unmarked is a risk for both sites.
User-generated content (a comment, a forum post). No transfer of value should be expected.
The page has no link to your site. It may have been removed, the page may load it later in the browser, or the address may have changed.
Worth knowing
A page-level rule overrides link-level markup. If the page itself carries meta robots nofollow, none of its links passes value, even if each one looks clean. The tool checks this separately.
Redirect links. Some sites do not link to you directly; they route the link through an intermediate address of their own. The target then does not look like your site. The tool warns you when it suspects this.
Pages built in the browser. On sites that load their content later with JavaScript, the link may not be in the page source. If the result says “not found”, open the page yourself and look.
This tool does not measure the value of a link. It only reports its technical state. Whether a link actually helps depends on how relevant and trustworthy the linking site is.
