This is one of those little free tools that can make your life much easier.

It`s a plugin for firefox that let`s you see all sorts of valuable data in your google search.

So instead of simply getting the results of your search, you also get all sorts of extra data on your search. Things like: Alexa page rank, number of backlinks, search ranking on various other engines (MSN, Yahoo, etc...)

It`s free, it`s good, I use it and if you want to have more insight into how competitive your keywords are, and how to beat the people above you in the search rankings ... then I suggest you give it a try.

This video outlines some of the features nicely.
