Just like spell checking, but for links
The Link Checker plugin acts just like a spell checker, but instead of checking spelling, it will let you know if a link in the editor is valid, invalid or questionable. This is a huge time-saver for anyone who creates content—no more having to double-check URLs, especially in imported content. Not to mention the benefit of no longer frustrating readers with broken links.
Additionally, if Link Checker thinks there is any possibility your link might not be valid, it will flag the link for you so that you can make an informed decision. Removing the flag is easily done by selecting “Ignore” from the new contextual menu we’ve introduced as part of this service.
