The three main ones include MSN, Yahoo and Google. Of which Google is the most common, as the strategies applied by Google are just duplicated by MSN and Yahoo. The understanding about the working of search engines was taken to a next level and made highly popular by Google with its reengineered search algorithm.
SEO stands for Search Engine Optimization, which is the unpaid way of increasing rank of a website. An effective SEO plays a vital role in indexing a website on main searches.
The first of the two basic types of search engines is called robots, known as crawlers or spiders. It is the crawlers or the spiders which are used by the search engines to index websites. It is through an incoming link or a words submission to put the website forward to a search engine, which further sends the crawler to visit the website. Where it reads the contents and titles of the actual site, the Meta tags and also follows the connecting sites. The information gathered by the spider is then stored in a central reservoir where it is indexed. The various links mentioned on the website are also visited by the crawler and indexed appropriately. Some spiders only index a limited number of pages on the website therefore; it is advisable to create a website with a maximum of 500 pages only.
A periodic and timely revisit of the Web Crawler to the site is dictated by the moderator of the search engines. This is done in order to identify any change in the information.
A spider has the capacity to index million pages per day as it is similar to a book which is inclusive of table of contents, the actual content and all the references and links found by it during the searches. When the request to locate information it searches through the index in contrast to the web. A variety of search results are provided by the search engines due to use of different algorithms.
