Basic concept about seo

In simple way we can define Seo as 

Search Engine Optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results for targeted keywords. Usually, the earlier a site is presented in the search results, or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines.

The Three Main Components of SEO Are

1. Site Content

2. Meta Data

3. Inbound Links
