UPDATE on April 3, 2011 – More the a year has passed since I have first published this article. I have since discovered a much better plugin that can help you optimize your WordPress website for the search engines. The plugin is called WordPress SEO.
One of the most important plugins for WordPress websites is “All in one SEO pack”
SEO, search engine optimization, is a term used to describe the action taken to improve the ranking of your website in the search results of the different search engines such as Google, Bing and others.
This plugin makes it easy to setup basic parameters of your website. Although most of these parameters no longer impact your actual ranking they do reflect at the quality of your site.
Description: Description is used by many search engines as the summary description for your page when your page is listed in the search results. When displayed in the search engine results, the description helps the searcher decide whether or not your page is relevant to their search. It’s what compels a real person to click your link.
