How your site is organized, designed, and built will affect its search-engine ranking, according to Andy Robson, managing director of the website marketing firm dzine it. Organize content into themed categories, what Clay calls silos. "By lining up your content by the way people search, you define to the search engine what you're about," Clay says. You can either group similar pages together into separate directories of folders and subfolders, or you can create "virtual silos" by using links that guide a user from one page to the next.

Other strategies are more technical, so you may need to rely on a Web developer for assistance. The site must be hosted on a fast server. The page code should be free of bugs and fully comply with the standards for website structure set by the World Wide Web Consortium. (You can test this at validator.w3.org.) Include in the site's code a special protocol known as Sitemap, which makes it easier for visiting search engines to scan the site. Sitemaps can be submitted directly to the search engines.
