📈 Link Analysis: Why It Matters for SEO

Links are the foundation of SEO. Internal links help search engines understand site structure and distribute PageRank. External links can pass authority to other domains (dofollow) or not (nofollow). Understanding your link profile is essential for avoiding penalties, improving crawlability, and maximizing link equity.

🔍 How Our Link Analyzer Works

We parse your HTML and extract every <a> tag with an href attribute. For each link we determine:

  • Internal vs External: Internal links point to the same domain (relative or same-hostname). External links go to other domains.
  • Dofollow vs Nofollow: Links without rel="nofollow" (or sponsored/ugc) are dofollow and pass PageRank. Nofollow links do not.
  • Anchor text and URL: We display the full destination for easy auditing.

📊 Understanding Your Results

  • Dofollow/External ratio: A page with many external dofollow links may leak PageRank. Use nofollow for untrusted or paid links.
  • Internal links count: Important for deep crawling. Ensure important pages have internal links.
  • Nofollow links: Not necessarily bad – used for comments, ads, or user-generated content.

⚠️ Common Link Issues

  • Too many external dofollow links: Can dilute authority. Use nofollow where appropriate.
  • Broken internal links: This tool only checks existence, not validity – use a broken link checker for that.
  • Missing anchor text: Link without text is less valuable for SEO.

🚀 How to Improve Your Link Profile

  • Maintain a healthy internal linking structure – every page should have at least a few internal links.
  • Use nofollow for affiliate, sponsored, or untrusted external links.
  • Avoid excessive external links – a few high-quality references are fine, but dozens can be spammy.
  • Check for duplicate link targets – multiple links to the same external site can be consolidated.

❓ Frequently Asked Questions

What is the difference between internal and external links?
Internal links point to pages on the same website (e.g., /about or https://yoursite.com/contact). External links point to other domains. Internal links help with site architecture; external links can build relationships but also leak authority.
How do I tell if a link is dofollow or nofollow?
Dofollow is the default. If a link has rel="nofollow", rel="sponsored", or rel="ugc", it is nofollow. Our tool detects this automatically.
Is my HTML stored or sent anywhere?
No. All processing happens in your browser. Your HTML never leaves your device.

Important Note

This tool analyzes links from static HTML. Dynamic links added by JavaScript after page load are not captured. For full accuracy, use browser DevTools or paste the fully rendered HTML source.
