Search engine optimization, also known as SEM, is an internet marketing strategy used to increase the number of visitors and potential customers to a site or a specific web page. SEM aims to increase the volume and quality of site traffic by optimizing the search results that appear on the internet. SEO targets free traffic rather than paid traffic or direct traffic.
There are a number of elements of search engine optimization, including meta tags, keywords, headers, page titles and content. All these play an important role in search query optimization. A good example of a keyword is “my car.” This keyword will show up in both the meta tag and in the webpage title, thus helping search engines understand what the page targets.
