Mcneri: SEOBook

#1: SEO for Firefox add-on
This is the number one Firefox add-on for bloggers. It is much the same idea as other Firefox browser add-ons, but it makes a huge difference when it comes to assessing web pages.
There are several aspects that I will touch on however this post can not be exhaustive, as there are many other aspects beyond the scope of the write-up.

It makes in-depth searching a breeze. This add-on is very nifty and easy to use. The writers advice that it is toggled off and on, based on need. After installation, the button sits at the bottom of your browser screen. When you want to search for the ranking of a web page like SEOBook, all
you have to do is go to the page, then turn the toolbar on (by clicking on it in the lower part of your browser) and then right-clicking anywhere in the homepage which you have opened.
Then select SEOforfirefox>Look up this page. The result is an array of values including Google Pagerank, the Google Cache date, date page was written,Yahoo links, Alexa Rank, DMOZ rank and other parameters.

This tool makes it possible for a blogger to be able to quickly assess the authority of any web page and to know whether to link to it or not.

Another capability of this add-on is in the area of regular Google and yahoo searches. Ordinarily, these major search engines do not give you details of things like Keyword research, Traffic estimator for that keyword, trends for that keyword and a host of other things. It also gives you the SEO details of each of the pages in the search results.
