The PAGE1 SEO Backlink Checker is a Chrome extension designed to help users analyze and visualize backlinks on any visited webpage. This tool provides detailed information about each backlink, including its type—internal or external—and its status as a dofollow or nofollow link. Users can also highlight backlinks by toggling their background color, enhancing visibility on the page.

To utilize the extension, users need to download it from the Chrome Web Store and activate it via the toolbar. Once activated, clicking the "Check Again!" button scans the current webpage for backlinks, displaying results in a clear table format. The extension requires permissions to access the active tab and modify webpage content, ensuring a smooth user experience for backlink analysis.
