What is SEO and how it works?

SEO is an acronym that stands for search engine optimization, which is the process of optimizing your website to get organic, or un-paid, traffic from the search engine results page. It involves making certain changes to your website design and content that make your site more attractive to a search engine.
In order to do this, search engines will scan, or crawl, different websites to better understand what the site is about. This helps them deliver more relevant results to those who are searching for certain topics or keywords. SEO is the process that organizations go through to help make sure that their site ranks high in the search engines for relevant keywords and phrases. By improving your SEO, you can expand your visibility on the search engines.
