Bold, Italic, and Emphasis

When you've used up your quota of header tags on the page, don't stress out. There are still plenty of tools to target your keywords with. When mentioning your keywords throughout the page, it's helpful to put them into italics, bold, or emphasis (<em>) to make sure the search engines know that these words are important.
Often people use a lot of flash animations and CSS <span> tags to format text, but search engines don't have an easy way of determining either of these. Why make the search engines work harder than they need to? Use these basic HTML tags and help yourself (and the engines) out!
