In a simple language, SEO means making your website ranking on search engines. For example, there are thousands of websites related to cooking. Some are genuine and some are a fraud. How does a search engine like google know which website is available and most relevant? In this case, SEO comes. SEO tells search engines that this is a cooking website and it is a genuine site. And based on popularity and content, google rank that website on top of his search result. Google is a fully automated search engine that uses software known as “web crawlers” that explore the web on a regular basis to find sites to add to their index.
