The Internal & External Link Analyzer scans a block of HTML and extracts every href link, classifying each one as internal, external, or nofollow so you can quickly review your page's link structure. Strong internal linking helps distribute authority across your site and helps users and crawlers discover related content, while unintentional dofollow links to low-quality external sites can dilute your page's trust signals. This tool is built for SEOs auditing link equity distribution, content editors checking outbound links before publishing, and developers verifying that nofollow attributes are applied correctly to sponsored or user-generated links. Paste in your HTML and get an instant categorized breakdown - processed entirely in your browser, with no upload and no signup. Reviewing your link mix regularly is one of the simplest ways to catch broken internal linking opportunities and unintentional link equity leaks. Scroll down to paste your HTML and analyze its links now.

Frequently asked questions
What's the difference between an internal and external link?
Internal links point to another page on the same domain, while external links point to a different domain entirely.
Why does the nofollow attribute matter?
It tells search engines not to pass link equity or ranking credit through that link, commonly used for sponsored content, ads, or user-generated links.
What's the difference between nofollow, sponsored, and ugc rel attributes?
Sponsored marks paid or advertising links, ugc marks user-generated content links, and plain nofollow covers general cases - all three tell Google not to treat the link as a natural endorsement.
How many internal links should a page have?
There's no fixed number, but linking to genuinely relevant related pages helps both users and crawlers, while excessive unrelated links can dilute value.
Do external links to authoritative sites help SEO?
Linking to high-quality, relevant external sources can support content credibility and user experience, though it's not a strong direct ranking factor.
Should I audit outbound links for broken URLs?
Yes, broken outbound links hurt user experience and can slightly undermine trust signals, so periodic link audits are good practice.
Can this tool check if links are actually live?
This tool extracts and classifies links from HTML; checking whether URLs return a live 200 status requires a separate link-checking crawl.
