I redesigned a union web site a few months ago using only CSS to manage the layout and all the positionning. It is now powered by a CMS (spip).
While I was at it, I modified the html page to put the main div (the middle column) at the top of the html page and all the "decorative" elements (the logo, top banner and top menu) at the bottom of the html. This web site had a Pagerank 4 and now it's at 5 (according to googlebar), althought I strongly suspect other elements (more incoming links) as being the main reason for this increase.
However, google has dropped some pages, like the home page or just kept the URL for some others. In fact, most of the pages it has kept on its index are old pages or documents from the previous web site.
I've read threads on this forums about other sites having the same problem and I don't think it's because the web site contains duplicated content from other web sites nor that it has been down.
In fact, the only reason I could see mentionned is that I'd tried to trick google and I've been caught.
Would it be possible that google think the CSS optimisations I've used are spam ?
Any suggestion welcome.
