is search engines that finally bring to the side of potential customers. Therefore, it is better to know how these search engines actually work and how to present information for client to initiate a search.
There are two types of search engines. The first is called robots or spiders robots.
Search Engines use spiders to index. After you submit the site to search engines by filling out the required page opinion, the search engine spiders will crawl the entire site. spider "is an automated program that is run by the search system. Spider's Web site, you read the actual location, site meta tags and also follow the links that a page of links. Spider then returns all that information back to the central deposit, in which the data are indexed. Will take place in each and every link you have on your website and index those sites as well. Some spiders only index a certain number of pages in your site, so do not create a site with 500 pages!
spider will periodically return to the places to check any information that has not changed. The frequency with which this happens is determined by the moderators of the search engine.
spider is almost like a book where the list of contents, actual content and links and references for all parties finds during the search, and can index up to a million pages a day.
Example: Excite, Lycos, AltaVista and Google.
When you ask a search engine to find information, it is actually searching the index, which has created and not actually searching the Web. Different search engines produce different rankings because not every search engine uses the same algorithm to search using indexes.
One of the things that the search algorithm looks for is the frequency and location of keywords on a web page, but it can also detect stuffing words key or artificial spamdexing. Then the algorithms analyze the way in which pages link to other sites on the web. By checking how pages link to each other, the engine can also determine what is a website where the keywords these pages are similar to keywords on the original page.
