Link Important for SEO

Text Links are very important to search engines, since anchor text often succinctly labels the content of a linkĄ¯s target page. In fact, many search engine optimizers consider anchor text to be the single most important factor in modern search algorithms. If a website uses an image map rather than a text-based menu as the primary navigational method, a redundant text-only menu elsewhere on the page will give search engines additional information about the content of each target page.

In Using XHTML/CSS for an Effective SEO Campaign, Brandon Olejniczak explains that many web design best practices overlap with those of white-hat SEO. The reason is simple: such practices as separating style from content, minimizing obtrusive JavaScript, and streamlining code allow search engines to more easily spider, index, and rank web pages.
