SEO is a technique which helps search engines find and rank your site higher than the millions of other sites in response to a search query. SEO thus helps you get traffic from search engines. In other words we can say that it is the process of improving the visibility or appearance of website, web pages in the unpaid search result.

Whenever you enter any query and press enter you will get websites or web pages that include that query. Normally a user visits those websites which appear on the top of the search. This is because of the power full marketing technique called SEO.

SEO Company perform several activities to provide search results. These activities include crawling, indexing, processing, calculating relevancy & retrieving. The leading search engines use crawlers or spiders to find search results. Spiders follow links from one page to another and index everything they find on their way. To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots.

After crawling a page, the next step is to index its content. The indexed page is stored in a giant database, from where it can later be retrieved. Essentially, the process of indexing is identifying the words and expressions that best describe the page and assigning the page to particular keywords.

When any search request is made than search engine process it by comparing the search string by index pages. There are various algorithms to calculate relevancy. Each of these algorithms has different relative weights for common factors like keyword density, links, or meta tags. That is why different search engines give different search results pages for the same search string.

The last step in search engines' activity is retrieving the results. Basically, it is nothing more than simply displaying them in the browser – i.e. the endless pages of search results that are sorted from the most relevant to the least relevant sites.
