Search engine optimization (SEO) is the process of improving the quality and quantity of traffic to a website from search engines. SEO responds to organic (natural) results. A website that ranks higher on search engines will have better visibility, which increases the chances of converting visitors into customers. The leading search engines, such as Google and Bing, use automated “crawlers” to find pages for their algorithmic search results. Search engines also index websites, meaning they store and organize available content to be displayed in search results. Sites are then ranked and displayed in order from least to most relevant based on the searcher’s given query.
