SEO is the process of making changes to your website design and content in order to help it appear in the search engines. By optimizing your website for the search engines, you can increase your visibility in the organic, or un-paid, search engine results.
Search engines like Google, scan your site, looking at design and content elements to help them determine what type of topics your website discusses and how user-friendly the site is. It helps the search engine deliver more relevant and useful search results to its users.
By improving SEO, your business is working to make it easier for search engines to understand and index your content. The better your website looks to the search engines, the more likely they will be to recommend your website or post to relevant search engine users when they look for keywords that are relevant to your product or service offering.
