I have a great idea of impressive seo and link exchange on the footer, whitch i think would be very nice to rank different pages, but i have no idea of how to make this so here is mod request if anybody knows how to make this:

The footer is included and its crossover, my mod request is that a page can have multiple footers, for different pages like

page=nokia.php <-footer whit nokia links
page=ericsson.php <-footer whit ericsson links
page=motorola.php <-footer whit motorola links

Great idea? I think this would be a perfect way to change links whit others and have the links related whit the containt = high seo?
