When implementing new content on your website, you should not only ensure the copy is current and conducive to the needs and desires of your website visitors, it is critical that you ensure it is also search engine friendly. Pay attention to the length of the copy, the number of keyword phrases you are targeting, the density and proximity of keywords, and the number and format of links within the text. Your website’s content is one of the most crucial areas to focus on when implementing a search engine marketing strategy as the copy on your website serves as “food” to search engine spiders. As such, proper content enhancement can improve your website's ranking performance in search engines. Furthermore, if a website is complex or large, with hundreds or thousands of pages, it is critical that content be categorized and in some cases, separated into sub-domains. This allows spiders to easily locate pages and may help to achieve additional directory listings on individual sections of your website.
