Link Checker: internal, external and nofollow links.
Enter any page to list every link on it, see which are dofollow, and find broken links. Free, with no signup.
How to check the links on a page
- Enter the page URL. Any public web page works: a blog post, your home page, or a page that should link to you.
- Choose whether to test for broken links. This also requests each linked page (up to 150) and reports its HTTP status. It takes a little longer.
- Review the report. Filter by internal, external, dofollow, nofollow or broken links, search by URL or anchor text, and download everything as a CSV.
What to look for
- Broken links (404 errors). They waste visitors' time and crawl budget. Fix or remove them.
- Too many external dofollow links. Linking out is normal, but paid or untrusted links should carry rel="sponsored" or rel="nofollow".
- Weak internal linking. Important pages should get internal links with descriptive anchor text, not "click here".
- Missing anchor text. Image links need alt text, which acts as the anchor text.
- A page-level nofollow. A robots meta tag with "nofollow" silently turns every link on the page into a nofollow link.

Link checker questions
What does the link checker show?
Every link on the page you enter: its URL and anchor text, whether it is internal (same website) or external (another website), and whether it is dofollow or marked nofollow, sponsored or UGC. Tick the broken-link option to also see the HTTP status of each link.
What is the difference between internal and external links?
Internal links point to other pages on the same website, including its subdomains. External links point to a different website. Internal links help visitors and search engines move around your site; external links send them elsewhere.
What do dofollow and nofollow mean?
A dofollow link is a normal link. A link with rel="nofollow", "sponsored" or "ugc" tells search engines not to treat it as an endorsement. If the page itself has a robots nofollow rule, every link on it counts as nofollow, and the checker tells you so.
Can I use it to verify a backlink?
Yes. Enter the page that should link to you, choose the External filter and search for your domain. You will see whether the link exists, its anchor text and whether it is dofollow.
Is it free?
Yes. The link checker is free with no signup. Each check reads one page and up to 1,000 links. To keep the tool fast for everyone, each visitor can run 15 checks every 10 minutes.
