I think your conversion went up because users were able to easily see a demo of the product.<p>I personally think that the tour (of your homepage) does is not much useful otherwise - it just goes through all the elements one by one, the graphic design of the tours interferes with the design of the page, and the large amount of text in the tours makes it hard to understand whats different with the information in the tours.<p>I would love to see you try a couple of things and let us know how the conversion rate changed (it will also help us know the best practices when using your service):<p>- try the tours with a similar theme as the site (as is currently the case), but do more to separate them - perhaps by adding rounded corners, more shadows, or changing what are the main colors in the tour.<p>- try reducing the text in the tours.<p>- try putting in content in the tours that is different from the current site content - perhaps by grouping the features on the site and your tours introduce them as groups, or perhaps by focusing your tours on the benefits (as opposed to the features).
