About the Link Extractor

This tool fetches any webpage and performs a comprehensive link analysis. It extracts all <a href> links and evaluates your page's link profile for SEO health. Perfect for link audits, competitive analysis, and technical SEO checks.

Total Link Count

Shows the exact number of links found on the page, helping you understand the page's linking structure and density.

Internal vs External

Separates links pointing to your own domain from those going to external sites, essential for understanding link equity flow.

Rel Attribute Detection

Identifies nofollow, sponsored, and UGC attributes so you can verify correct usage of Google's link classification system.

Why Link Analysis Matters for SEO

Links are one of the most important ranking factors in Google's algorithm. Every link on your page sends signals about your content's quality, relevance, and trustworthiness:

  • Internal links distribute PageRank across your site, help search engines discover new pages, and define your site's information architecture. A well-internal-linked site ranks better because link equity reaches deep pages.
  • External links to authoritative sources improve your content's credibility and can positively influence your own rankings. Google views well-researched content with quality outbound links as more valuable.
  • Nofollow vs Dofollow — Using nofollow correctly on paid/sponsored links prevents Google penalties. Overusing nofollow on organic editorial links wastes link equity that could benefit your readers and your site.
  • Anchor text provides context to both users and search engines about the linked page's content. Descriptive, relevant anchor text improves click-through rates and helps Google understand your content structure.
  • Link density — A page that is 50% links may appear spammy. Maintaining a healthy text-to-link ratio signals quality content.

Best Practices for Healthy Link Profiles

  • Maintain a link density below 10% for content pages
  • Use descriptive anchor text (avoid "click here" or "read more")
  • Include 2–5 internal links per page to related cornerstone content
  • Link to 3–5 authoritative external sources per article (where relevant)
  • Use rel="sponsored" for affiliate/paid links and rel="ugc" for user-generated content
  • Add rel="noopener noreferrer" to all target="_blank" links for security
  • Ensure all links use HTTPS for consistency and security
  • Diversify external links across multiple authoritative domains
  • Avoid excessive nofollow on editorial links — let link equity flow naturally

Frequently Asked Questions

The Link Extractor fetches any webpage and finds every <a href> link. It reports the destination URL, anchor text, whether the link is internal or external, rel attributes (nofollow, sponsored, UGC), target="_blank" behavior, and provides summary statistics like total link count, link density, and external domain diversity.
Internal links point to the same domain as the page being checked. External links point to a different domain. Relative links (like /about, /contact) are always classified as internal. The tool compares the link host against the page host to make this determination automatically.
Link density is estimated as the ratio of links to the approximate text content of the page. A very high link density may suggest a link farm or navigation-heavy page, while a low density could indicate thin content. Well-written articles typically have 1–3 links per 100 words of body text.
Links with rel="nofollow" tell search engines not to pass PageRank or ranking credit to the destination URL. Google treats nofollow links as hints, not directives. Nofollow is commonly used for paid links (sponsored), user-generated content (UGC), comment sections, and untrusted external sites to avoid passing link equity.
rel="sponsored" identifies paid or affiliate links under Google's 2019 link attribute guidelines. rel="ugc" (User Generated Content) marks links from forums, comments, or other user-contributed content. Both are more specific alternatives to nofollow and help search engines understand the nature of the link relationship better.
Using target="_blank" opens the link in a new tab, which some users prefer for external links. However, for security, always add rel="noopener noreferrer" alongside target="_blank" to prevent the opened page from accessing the original page via window.opener. Excessive use of _blank on internal links can also create poor user experience.
There is no hard limit, but best practices suggest 2–5 high-quality external links per 1,000 words of content. Too many external links may dilute your page's ranking signals. Too few (or none) may make your content appear poorly researched. Each external link should add genuine value for the reader.
A healthy internal linking strategy includes 3–10 internal links per page, linking to relevant cornerstone content with descriptive anchor text. Internal links distribute PageRank throughout your site, help search engines discover new pages, and guide users to related content. Avoid excessive navigation links that overwhelm the main content.
