It is generally believed that the closer the content is to the top of the page, the better it is for SEO. If that's incorrect, please let me know.
I have a 2 column site where the left menu is navigation and right side is content. Obviously, the left menu appears in the code before the content does, but I can flip them around via css float. If I do that, the content will appear on the left visually, even though in the code it still comes after the left side navigation.
Do either positions affect seo?
