Search engine optimization is the process of maximizing the number of visitors to a particular website by ensuring that the site appears high on the list of results returned by a search engine. Search engine optimization is also referred to as SEO. For instance, some examples of SEO best practices are:
content with keyword phrases
Internal page linking
A good SEO strategy means organizing your website’s content by topic. This helps search engines like Google understand user intent.
SEO and SEM are not the same. You cannot use these acronyms interchangeably. While both processes increase website visibility, Search Engine Optimization is a long term play.
