"Search engines love content." We have made that comment over and over throughout the years. Search engines like Google, Yahoo and Bing use your content to connect it to people who are searching for you or your service. The more quality content you have on your website, the greater the chance your site will be indexed by the three major search engines.
Having quality content on your site is only the first step. Your content must always be evolving.
People evolve. Their habits evolve. Their needs evolve.
