Before explaining about SEO I want to tell how search engines are working

SEARCH ENGINES BACK END WORKS

The search engines perform much operation to deliver search results while end users entering specific search keywords.

Crawling / spidering

The first thing after a webpage uploaded in the web server is search machine crawling  the website. The word crawl otherwise called as spidering in SEO. The task crawling done by the software crawler.  Spiders follow links from one page to another and index everything they find on their way.

crawlers do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site, you'd better run the Spider Simulator below to see if these goodies are viewable by the spider. If they are not viewable, they will not be spidered, not indexed, not processed, etc

Indexing

After a page is crawled, the next step is to index its content. The indexed page is stored in a huge database, the database can be queried later. Essentially, the process of indexing is identifying the words and expressions that best describe the page and assigning the page to particular keywords. For a human it will not be possible to process such amounts of information but generally search engines deal just fine with this task. Sometimes they might not get the meaning of a page right but if you help them by optimizing it, it will be easier for them to classify your pages correctly and for you – to get higher rankings.

Processes

When a search request comes, the search engine processes it – i.e. it compares the search string in the search request with the indexed pages in the database. Since it is likely that more than one pages (practically it is millions of pages) contains the search string, the search engine starts calculating the relevancy of each of the pages in its index to the search string

calculating the relevancy

There are various algorithms to calculate relevancy. Each of these algorithms has different relative weights for common factors like keyword density, links, or metatags. That is why different search engines give different search results pages for the same search string. What is more, it is a known fact that all major search engines, like Yahoo!, Google, MSN, etc. periodically change their algorithms and if you want to keep at the top, you also need to adapt your pages to the latest changes. This is one reason (the other is your competitors) to devote permanent efforts to SEO, if you'd like to be at the top

Retrieving

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.
