Google Launches Website Optimizer
Google has created a really easy way for web developers to optimize conversion rates on their web site.
Its currently being beta tested, but the Google Website Optimizer looks like it is going to be a really useful tool for micoISVs, or anyone for that matter, who want to test and improve conversion rates on their web site.
Web site developers place a code snippet on their web site, just like with Google Analytics. Then you can create modified versions of your landing page with different headlines, images or content. Google will then randomly display one of the modified pages to web site visitors. You will then be able to track which page provides the best conversion rates.
