There are no broken links
(M) There are no broken links
Websites are not static, they must be maintained and frequently updated with new information in order to maintain a ‘fresh’ look. Furthermore, with more people involved in maintaining content, more opportunities arise for alterations in website structure that lead to dead/broken links or 404 error pages that indicate a particular web page is not available. The situation is worse with external links where you have no control over what other people are doing on their websites.
Link checking software. Check your website for broken links regularly using a link checker and fix them in a timely manner (e.g., link checker: http://validator.w3.org/checklink). Alternatively, IW:LEARN can provide link checking reports for your site.
Managing file names. Use understandable, keyword rich filenames. When content is replaced keep the same file name to avoid broken links.
User-friendly error pages. Provide user-friendly guidance to error pages associated with broken links.
Check web analytics for your website. In addition to information useful for improving website usability and improving search engine optimization, web logs and user statistics provide useful information about website problems. Broken links and hacking attempts may show up on these reports.
