Instant Rank Checking
I’ve recently stumbled on this usefull Firefox addons, called SEOQuake. Which is very usefull when I want to check one page’s Google PageRank (and other statistical info).
Why do I need to do so?
Well, it’s a common thing that to gain the pagerank juice, one need to earn backlinks (or inbound links) from other page that has high Page Rank. I’m not telling that a visiting a blog then leaving your comment is merely a way to gain page rank juices, but when it comes to that.. well, this one addons will help.
Not only you will get the information when you open the page, even when you’re still on a Google Result Page, you will see the statistical information for each resulting links. So, happy hunting y’all.
