External Link Analyzer — Find & Analyze Outbound Links Free

Linking to authoritative, relevant external sources is a positive quality signal. It shows Google your content is well-researched. Avoid linking to low-quality or spammy sites.

A nofollow link (<a rel='nofollow'>) instructs search engines not to pass PageRank to the destination. Use nofollow for paid links, user-generated content, and links to sites you can't vouch for.

Adding target='_blank' to external links keeps users on your site while they view the linked resource. Include rel='noopener noreferrer' alongside target='_blank' for security.

Enter a competitor's URL into the tool to see all their external links with anchor text. This reveals their citation sources and can inspire content and link-building ideas.

No — linking to high-quality, relevant external sources is an SEO best practice. It signals to Google that you're citing authoritative sources and adds context for readers. Avoid linking to low-quality or spammy sites.

A dofollow link passes link equity (PageRank) to the destination. A nofollow link (rel='nofollow') tells Google not to follow or pass equity through it. Use nofollow for paid/sponsored links, user-generated content, and untrusted sources.

There is no hard limit, but each outbound dofollow link dilutes the page's internal PageRank distribution. Pages with hundreds of external links often look thin to Google. Focus on quality and relevance over quantity.

Google introduced rel='sponsored' for paid/affiliate links and rel='ugc' for user-generated content links. These are more specific alternatives to nofollow, though nofollow remains widely accepted for both use cases.
