Link Attribute Highlighter - Nofollow Checker is a free Chrome add-on designed for SEO professionals and web developers. This tool visually highlights links on any webpage by categorizing them as dofollow, nofollow, sponsored, or UGC. The color-coded outlines make it easy to distinguish between link types instantly. Users can toggle the visibility of each link type and access a summary dashboard that provides total link counts and a bar chart for link attribute distribution.

The tool also offers an external vs. internal link breakdown and lists of top external domains with their respective rel attribute counts. With features such as one-click apply and clear highlighting, as well as a unique domain counter, this add-on streamlines the process of link auditing without collecting any data or making API calls, ensuring privacy and efficiency.
