Get started in three simple steps
Add LinkGlow to Chrome or Firefox from your browser's extension store.
Visit any page and LinkGlow automatically highlights internal and external links.
View link stats in the popup or save audits to your dashboard for later review.
Enter a URL or paste content to see how LinkGlow classifies links
Enter a URL to fetch and analyze its links. The domain will be automatically detected.
Try an example:
See internal and external links highlighted instantly on any webpage with customizable colors.
Group related domains together (like Envato + TutsPlus) to treat them as internal links. Browse domain groups
Choose highlight styles, colors, and configure which link types to ignore.
Get a quick count of internal vs external links right in the extension popup.
Compatible with SPAs and dynamically loaded content thanks to smart DOM observation.
Core highlighting stays local. Sync and AI features are optional, and AI uses a minimized page-structure summary only after you opt in.
Use CSS selectors to analyze only the links that matter. Skip navigation, footers, and sidebars to focus on your main content.
A well-organized internal linking strategy is crucial for SEO success. It helps search engines understand your site architecture and distributes page authority effectively.
According to Moz's SEO Guide, internal links should point to your most important pages. You can learn more about this in our link building tutorial.
