Search engine optimization is a method of getting your website to rank higher in search engines—such as Google, Yahoo or Bing. A search engine optimization campaign pairs on-site optimization with off-site tactics, which means you make changes to your site itself while building a portfolio of natural looking back links to increase your organic rankings. When Internet users search for your products or services, your website needs to be the first one they find. SEO helps the search engines recognize your relevance to specific keywords that people search for online. The search engine optimization process includes researching keywords, creating content, building links and making sure your website is visible in the search engines.
