An important part of any SEO plan, is social marketing. Google PageRank for your website comes through association with other websites that have high PageRank. Google determines PageRank by the number of people frequenting web properties. So basically, Google counts these visits, and the more visits you have, the higher your PageRank. Another way Google increases your site’s PageRank is by the number of links coming from sites such as Facebook Twitter and other popular sites. These links are known as ‘back-links” because they refer back to your site from very popular sites. Google sees these links as a sign of your relevance to people on the web. For Google, this relevance translates to popularity, which translates to better PageRank for your site. There are other benefits to social marketing but clearly improving organic search results is right at the top of the list.
