Internal and external link checker

Split a page’s links into internal, subdomain and outbound, then see every external domain it sends visitors to, and which of those links are followed.

Internal linking: the part of SEO you fully control

Search engines discover pages by following links, and they read the anchor text as a label for the page behind it. Google’s documentation on crawlable links makes the mechanics plain: use real <a href> elements (not click handlers on a div), with descriptive text.

  • Link from strong pages to important ones. Pages that attract backlinks (guides, tools, the home page) share that value through their internal links.
  • Keep important pages shallow. A page three clicks from the home page is found and recrawled more easily than one buried seven levels deep.
  • Fix orphans. A page with no internal links pointing to it is only reachable through your sitemap.
  • Watch the menu. Mega-menus with hundreds of links dilute every other link on the page and bury the ones in your body copy.

Outbound links worth a second look

The per-domain table makes three problems easy to spot: a single domain receiving dozens of followed links (often a leftover widget or a sitewide footer credit), followed links to affiliate or sponsor domains that should be marked sponsored, and outbound links to sites that no longer resolve. Run the broken link checker on the same URL to catch the last one.

Questions people ask

What is an internal link?

A link from one page to another page on the same website (same host name). Links to a different subdomain of your site are shown separately as subdomain links, because search engines may treat subdomains as separate sites.

How do I check outbound links on a page?

Paste the URL above and open the External filter. The per-domain table lists every external domain the page links to, how many links go there and how many of them are followed.

How many internal links should a page have?

Google has not set a number; its old guidance of “a reasonable number” still stands. What matters is that important pages receive links from relevant pages, every page is reachable within a few clicks from the home page, and anchors describe the target.

Can this find all internal links pointing TO a page?

Not by itself, as that needs a crawl of your whole site. Google Search Console’s Links report lists your most internally linked pages, and a desktop crawler such as Screaming Frog shows inlinks for every URL. Use this tool to check what a single page links out to.

Are external links bad for SEO?

No. Linking to useful, relevant sources helps readers and is normal on the web. Keep paid links marked sponsored, remove links to spammy or dead sites, and check that outbound links still work.
