Search Engine Optimization (SEO):
Search engine optimization (SEO) refers to methods used to increase traffic to a website by increasing its search engine page rank.
SEO often involves improving the quality of the content, ensuring that it is rich in relevant keywords and organizing it by using subheads, bullet points, and bold and italic characters. SEO also ensures that the site’s HTML is optimized such that a search engine can determine what is on the page and display it as a search result in relevant searches. These standards involve the use of metadata, including the title tag and meta description. Cross linking within the website is also important.
