Link checking

Links on a web page very quickly become broken (link rot) because we move, delete or change our own pages, and other people that we link to do the same. Using a link checker regularly will improve your website's user experience (UX) and search engine optimisation (SEO).

Integrity is the free link checker for Mac. It's OSX native, very fast and accurate.
