Google unleashed another web tracking service today, with an interesting twist. It allows you to create multiple versions of your landing page (and others?), then compares the stats allowing you to adapt thus, hopefully improving your site. As is the norm it has entered the long google beta, and while its too early perhaps to ask for people's opinion lol, I do have a couple questions.

Will this tool show you anything you can't already see by using Google Analytics and various other tools? Who has time to setup a half dozen (the reports screen shot showed 22 I believe) different variations of a landing page? Is this the next gen the community needs? I look at stats, and react accordingly, if everyone is missing an important link or dropping off at stage 3 of 5 before a conversion can be made, I try something new. From what I can see you'll now be able to try multiple strategies together, but could this not also hurt your site? A landing page is very important, so you try 5 varietys and lose 200 visitors to a bad one, quickly swap it out but not before the loss. I am curious as to what others feel or predict the usefullness of such a tool can and will be. btw sorry if my post is too long or asks to much, tis my first Webmaster World Post :)
