"The best way to begin an optimization project is to make sure that all your code is readable. Search engine spiders work much the same way that the human eye does, and if there’s too much “junk text” in your HTML, it’s going to be hard for spiders to know what is what and to be able to decide that a page is relevant to a particular category. Improving your structural organization will not only make it easier to read for you, but ensure that search engine spiders know what you’re trying to show them."
