Basically the search engines read pages that have been submitted to it via a Search Engine Submission form. From there it reads the entire page, boils it down to essential keywords and adds all the links it finds to the search list. Then it takes the next page off the list and starts all over again. You can see that just one submission to a search engine can generate thousands of pages in its database. All pages on the Internet are subject to being scanned by a search engine. If you don’t want your pages to be scanned you have to take steps to prevent it. You can do this with Meta Tags or a small file named robot.txt located on your site.

The simple fact is that every search engine does things a little bit differently and the method for collecting, cataloging and rating the data that it does have changes probably on a daily base. Also the people who create these search engines would rather not tell us how it’s all done. If I told you how to get your site at the top of search engines would you? Most people would say yes. Be honest now, does your site belong at the top of the search engines? Is it the best site in your category? If not, you’d be cheating the system, and that’s what the creators of these search engines hope to prevent. Remember this is just software lurking around the Internet trying to determine which sites are the most relevant to any particular search query that they get at some future time. Basically what they hope to be able to come up with is a system that brings the most relevant and substantial site to the top of each query no matter what the category may be.

There are two types of search engines: Search Engine Directories and Search Engine Spiders. Each search engine (regardless of whether it is a search engine spider or a search engine directory) uses unique criteria for "ranking" websites.

1.

Search Engine Directories rely on humans to gauge web page relevancy and search engine placement. Human editors review each website and rank them according to a set of guidelines such as website content, website functionality, and website design professionalism. Yahoo! and the Open Directory Project, DMOZ are the most popular Directory Driven Search Engines.

2.

Spider driven search engines use "robots" to spider websites across the Internet. Robots "crawl" each website and "score" pages based on relevancy. Some engines score the index page while others score individual web pages. A website's score or placement within a spider driven search engine is derived from hundreds of variables such as, link popularity, click popularity, keyword density, website themes and more. Google.com is the most popular spider driven search engine.

Every Search Engine ranks Website Relevancy using a unique formula. Another term for a search engine's ranking formula is a search engine algorithms. The goal in search engine optimization is to build a website that meets each search engines "ranking criterion. The closer a website matches each search engine's "ranking criterion, the higher the website scores. Higher scores equal better placement in search engines. The best scores are rewarded with Top 10 search engine placement.
We make Sites compatible with the technologies, Search Engines adopt to index a particular site. Using technology we can see what the Spiders see on the pages thus giving us a better insight into what is needed for higher rankings. We know the variety and complexity of search engine's "ranking" algorithms and keep ourselves updated with all the modifications in Search Engines "Page Ranking Criterions".
We take care of the following things while making a Website Search Engine friendly.
