Search Engines Function – Web Crawlers

Did you ever wonder how You can Developing A Niche?

It is the search engines that ultimately fetch your website to the discovery of the potential customers. Therefore it is more favorable to recognize how these search engines really function and how they deliver information to the customer starting a search.

There are fundamentally two types of search engines. The first is by robots called spiders or crawlers.

Search Engines utilize spiders to index websites. When you submit your website pages to a search engine by filling out their required submission page, the search engine spider will index your entire site. A ‘spider’ is an automated program that is run by the search engine system. Spider visits a web site, read the content on the existent site, the site’s Meta tags and also adopt the links that the site connects. The spider then returns all that information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites too. Some spiders will only index a certain number of pages on your site, so don’t create a site with 500 pages!

The spider will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the moderators of the search engine.

A spider is virtually like a book where it contains the table of contents, the actual content and the links and references for all the websites it finds during its search, and it might index up to a million pages a day.

Example: Excite, Lycos, AltaVista and Google.

When you ask a search engine to locate information, it is actually searching through the index which it has created and not in reality searching the Web. Different search engines produce different rankings because not every search engine uses the same algorithm to search through the indices.

Among the things that a search engine algorithm scans for is the frequency and placement of keywords on a web page, but it can as well discover artificial keyword stuffing or spamdexing. Then the algorithms analyze the way that pages link to other pages in the Web. By checking how pages link to each other, an engine can both determine what a page is about, if the keywords of the linked pages are similar to the keywords on the original page.
