Search Engine Optimization (SEO) is a strategy to understand and leverage how search engines like Google and Yahoo! rank results. The goal is for your website to be listed at the top of relevant search results so prospects investigate your offerings before those of your competitors. There are two types of search engine optimization strategies: organic and paid. Organic SEO involves building your website in such a way that search engine spiders find key words and links so that your site comes up at the top of search requests. Paid SEO involves placing pay-per-click (PPC) ads on Google AdWords, Yahoo Overture, or other search engines. PPC advertising is a fast and effective way to generate leads and boost website traffic. Unlike organic SEO, which may take weeks to generate results, you can have a PPC ad up and running within a matter of minutes. Together, organic and PPC advertising can result in immediate leads and a significant return on marketing investment.
