Zouu !! C'est l'aventure.

The higher up content is in your page code, the more important it is considered by search engine algorithms (see my article on link source ordering for more details on how this affects links). To make your website as optimised as possible your main page content must come before the side columns. This layout does exactly that: The the right-hand main page comes first, then the left column (see the nested div structure diagram for more info). The columns can also be configured in the opposite order if required.
