Browse engine optimization involves coding web pages so they rank highly in search engines for targeted keywords. Most search engine optimizer's time should be spent targeting search engines that will provide the most traffic. It is best to consult a search engine optimization expert before building a website so they can advise on keywords and page design for optimal indexing. A quality search engine optimization expert will be able to get a site indexed well on Google, Inktomi, and Yahoo. If an existing site is not ranking well, an expert may recommend design changes to improve indexing, such as removing multiple frames. Search engine optimization helps potential customers find a website but is not a substitute for high quality content and design.
