 What is Search Engine Optimization (SEO)

Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engine. SEO targets unpaid traffic (known as "natural" or "organic" results) rather than direct traffic or paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academy search  , news search, and industry-specific vertical search engines.

How does SEO works

Search engines optimization (SEO) are used by people when they have a query and are searching on the internet for the answer. Search engine algorithms are computer programme that look for clues to give searchers the exact results they are looking for. Search engines rely on algorithms to find web pages and decide which ones to rank for any given keyword. There are three steps to how search engines work: crawling, which is the discovery stage; indexing, which is the filing stage; and ranking, which is the retrieval stage.
