Content Stacking - CSS positioning

[imageworks-261290]

I was curious to know what everyone thinks about CSS positioning so that the spiders will read a optimal bulk of content first - before it reads the others. Say I have some Tab's set up for navigational purposes, where the content in the last tab is actually what I want the bots to see first. What would be the best practices for accomplishing something like this?

I really see no problem with this within reason. Your best bet is to start by separating layout code into external CSS and Javascript files, so the majority of the code on your page is just simple HTML elements and text. This is 90% of the battle. Reorganizing the content so that your unique, valuable textual content occurs towards the top of the code is the remaining 10%. However, there haven't been any formal studies to prove that this matters much at all. My guess is that unless this is a change you are making on hundreds if not thousands of pages, you will probably see almost no improvement.
