What techniques or tools are recommended for finding broken links on a website?
I have access to the logfiles, so could conceivably parse these looking for 404 errors, but would like something automated which will follow (or attempt to follow) all links on a site.
For Chrome Extension there is hexometer
See LinkChecker for Firefox.
For Mac OS there is a tool Integrity which can check URLs for broken links.
For Windows there is Xenu’s Link Sleuth.
