Google Toolbar
If you have a browser then you must install Google Toolbar. Google Toolbar will be very helpful to find a lot of information about your websites. I had got IE7 and installed the Google Toolbar for it. I even installed it for Mozilla Firefox. You can improve your web browsing experience with Google Toolbar. The good thing is that it is a free software. The software comes with a built-in Pop-up Blocker and Search Site features. You can also see the PageRank of all the sites. This Google Toolbar will be very helpful for all webmasters.
