hi there
have you validated the coding through w3c, for the css and the xhtml, as i am led to believe that the googlebot, reads it all, and is looking for the easiest read, with regards to rankings, etc
the reason why i ask, as i have spent the past day and a half with web and email designers, to have a new website built, and email marketing sysyem as well.
i personally think it al depends what you are actually looking to achieve with your website, whehter you are looking to provide information for a potential client, as an online brochure, so that they then call you for mor info and a quote, or whehter you are using it as a hard sell shop window.
so good luck keep going
regards
martin
