What is External Link Checker?
An External Link Checker identifies links from the analyzed page to other hostnames and shows destination, anchor text and rel attributes. It is useful for reviewing citations, partner links, affiliate references and outbound resources without treating every external link as a problem.
Good outbound links can improve usefulness by letting readers verify claims or continue to primary sources. Problems arise when commercial relationships are not qualified appropriately, destinations are outdated or pages accumulate unrelated promotional links that weaken editorial trust.
How to use the External Link Checker
- 1Enter the page URL.
- 2Review the list of external destinations and anchors.
- 3Check rel values such as nofollow, sponsored or ugc where commercial or user-generated relationships exist.
- 4Open important sources and verify they still support the statement being cited.
- 5Use the Broken Link Checker when you want destination status sampling.
Understanding the results
- An ordinary external link is not inherently risky.
- rel=sponsored is appropriate for paid placement relationships where supported.
- rel=ugc can identify links created by users in user-generated sections.
- nofollow is a qualification signal, not a replacement for honest disclosure of commercial relationships.
Common problems
- Citations point to removed research or changed pages.
- Paid links have no disclosure or link qualification.
- Generic anchors hide where the link will take the reader.
- Old partnerships remain in evergreen content after the relationship changes.
- Pages link to HTTP versions that now redirect to HTTPS.
How to fix them
- Update important citations to current primary sources.
- Use appropriate rel attributes and visible disclosure for commercial relationships.
- Write descriptive anchor text when the destination is not obvious.
- Remove or replace irrelevant outbound links during content updates.
external links best practices
- Prefer primary sources for statistics, regulation and technical claims.
- Do not avoid useful external links merely to keep users on your domain.
- Review commercial relationships separately from editorial citations.
- Check evergreen guides periodically for link rot.
