The Science of SEO
Like a science, specific, known design techniques can be used (or not) by Web designers to improve a search engine’s ability to “read” the content of a Web site and its pages. Wonderful and complex Web sites can easily be created without using any SEO techniques, or by using techniques that directly interfere with a search engine’s ability to “read” the content of a site. If you want to determine whether your Web site has a fighting chance of being highly listed by a search engine, you need to be aware of these known and non-mysterious techniques.

The Art of SEO
Like an art, scientific techniques have to be employed in reference to a Web site’s purpose, audience, message, aesthetics, and contents. The “look and feel” of a Web site can be critical, and a balance must sometimes be struck between the artistic qualities of the Web site and its adherence to search engine requirements. Many “artistic” design elements actually interfere with or prohibit a search engine from reading a site.
