Highlights links on a webpage - internal, external, subdomain links, with broken link detection option Free Web Link Highlighter. Highlights links on a webpage - internal, external, and subdomain links are shown with "I" Internal links in green "E" External links in blue "S" Subdomain links in purple With optional broken link detection, which takes a little longer but displays broken links in red, redirects in orange, and unverified links in grey, still accompanied by the "I", "E", or "S" letter indicator as above. Either the basic data or the complete broken link check data can be optionally exported to a CSV file for further analysis, which includes all HTTP codes and redirection data. If broken links are checked, the icons displayed on the screen for links can be hovered over to show a tooltip containing information such as the HTTP code, whether the URL is redirected, and if so, where the redirect points. Used for SEO page link checking and can help when sometimes links are not visible due to page styling. This can also be quicker than running large commercial SEO tools, such as SEMrush, SERanking, Ahrefs, or Screaming Frog. Simply use this to check the links on a single page for free!
