How to use the link analyzer
- Paste the HTML of the page you want to audit into the box.
- Optionally enter your own domain so the tool can tell internal links from external ones accurately.
- Click Analyze links to classify every anchor.
- Read the summary counts, then scan the external domain list at the bottom.
Internal vs external links
Internal links point to other pages on your own site, while external links point to other domains. A healthy page uses internal links to pass authority and guide visitors through your site, and a measured number of external links to reference sources. Without a domain entered, the tool treats relative URLs like /about as internal and absolute URLs to other hosts as external, which is usually what you want.
Dofollow vs nofollow
By default, links are dofollow, meaning they pass ranking signals to the target. A link marked rel="nofollow" tells search engines not to pass that signal, which is useful for paid links, user comments and untrusted content. The analyzer reads each anchor's rel attribute and counts dofollow and nofollow links separately so you can see the balance at a glance.
Reading your external domain report
The external domain list groups every outbound link by host and shows how many links point to each. It surfaces which sites you link to most often — useful for spotting an unexpected outbound-heavy pattern, checking that affiliate or sponsor links carry nofollow, and confirming that legitimate citations outnumber anything that could look like a paid link scheme.
Why link classification matters
Search engines read your link structure to understand your site and its relationships. Too many external links to low-quality domains can drag a page down, while a clear internal hierarchy helps crawlers discover and rank your content. Knowing how many of your outbound links are nofollow also matters for compliance — affiliate and sponsored links should carry nofollow to stay within search engine guidelines. A quick classification pass makes all of this visible without any paid tools.
