what is seo ?
Search engine optimization is a methodology of strategies, techniques and tactics used to increase the amount of visitors to a website by obtaining a high-ranking placement in the search results page of a search engine (SERP) — including Google, Bing, Yahoo and other searchengines.

How SEO Works?
SEO is short for Search Engine Optimization, and there is nothing really mystical about it. You might have heard a lot about SEO and how itworks, but basically what it is is a measurable, repeatable process that is used to send signals to search engines that your pages are worth showing in Google’s index.
