Webmaster2 is a simple but pretty effective Webmaster Extension for FireFox. If you are a webmaster or web guru, then taking a look at this extension for your browser is probably worth a couple minutes. Webmaster2 allows you to see the popularity of links on pretty much any website you look at. Icons are displayed before the links that shows the page rank of the page, the quality of the domain, and projected traffic for the domain.
Now if you think about the number of links that some pages have on them, especially within just one post or article, you would think that having these little icons next to each one would be pretty annoying. Luckily the developers of Webmaster2 thought about that as well. Therefore, the addon does not display information for local links, links missing “http://”, links to Google and Yahoo, and any links to an IP address.
Now that will cut down on some of the mess on the page, but it is still a good thing that this can easily be switched on and off. I think if you are serious about your research, then this tool can be helpful to determine what could be a good link as opposed to another and possibly save you some time. It is also good for competition research.
