A broken link on your website is like a broken promise to your visitor: You did not provide the content you said you would. Broken links might cause some visitors to question your professionalism, competence or intelligence. Don't disappoint your visitors. Make certain that all the links on your website actually work.

The report will list all the broken links the checker was able to find on that page. The W3C Link Checker report also gives you the line number where you might find the broken link in the original HTML code. Open your Web editor and load the page you just checked. Search for the broken link. If you have trouble finding the link, try copying the broken link from the report, then use your editor's "Find" function to quickly locate it. Find and correct every broken link listed in the report or remove the links if they no longer are needed. Save the edited page. Open up your FTP (file transfer protocol) application and connect to your Web server. Transfer the edited file from your computer to your Web server. Log out of the server. Recheck the the Web page you just uploaded. If this page passes with no problems, repeat the process for each page in your site that has links.
