If you haven’t seen Quixapp from Yoast, it’s a really neat bookmarklet tool that makes it really quick to check all sorts of things about a site – from its speed, to whois. All it does is link quickly to various sites, directly using the URL you are on when appropriate.
Nothing complicated, but I’m amazed nobody has thought of it before.
Quixapp help shows a full list of all the quicklinks that he has already added, and a Majestic link has just been added. Simply put – if you use the free quixapp bookmarklet, then is you are on a website (say http://example.com) and type “maj” into the bookmarklet, it sends you straight to our website, with the URL “top level” data filled in.
