So if you have an addon like I'm going to tell ya right now... then forget about all that hassle, whenever you go to a web site this firefox addon will (free btw came a bit late oh did you close already :( ) display live Google page rank of that URL. Wait not only that it will also gives you information such as Alexa and mozranks, cache date, robot txt, keyword density and highlighting, Archive.org files (wayback machine), etc. It is called search status.
So these are just a few to name guys and if you're serious about blogging and making some cache out of it then I urge you to take advantage of this page rank (live) addon for firefox. Thanks. ... Oh almost forgot look below for the downloading link.
