Outbound Link Checker
Separate internal and external links by comparing against a base domain.
Input
Paste a base domain and the page's HTML.
Outbound Links
External links, then internal links.
Outbound Link Checker
Give the checker a base domain and a page's HTML and it splits every link into internal and external, so you can review who you link out to without installing a desktop crawler.
Step by step
- Paste the base domain of the page you are analysing.
- Paste the page HTML, or enter a URL and click Fetch Source.
- Click Check Links.
- Review the external links first, then the internal list, and copy either group for your audit.
Tips for better results
- Outbound links to relevant, authoritative sources give readers context — but a wall of low-quality links dilutes a page's focus.
- Check how external links open and whether paid or user-generated links carry the correct rel attributes.
- Re-run the audit after a content refresh; outbound links rot faster than internal ones.
Frequently asked questions
What counts as an outbound link?
Any link whose hostname differs from the base domain you entered, including links to subdomains that do not exactly match the base host.
How many outbound links should a page have?
There is no fixed number. Prioritise relevance and reader value, and remove links that no longer support the content.
Does the checker follow the outbound links?
No. It only reads the HTML you supply. Use the Alive URL Checker to confirm that external destinations still respond.
