How Do Search Engines Work?

It is the search engines that finally bring your website to the notice of the prospective customers. Hence it is better to know how these actually work and how they present information to the customer initiating a search.

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

‘Spiders’ are used to index websites. When you submit your website pages by completing their required submission page, the 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, reads the content on the actual site, the site's Meta tags and also follows 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 as well. 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 almost 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 may index up to a million pages a day.

Example: Excite, Lycos, Bing and Google.

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

One of the things that they algorithm scan for is the frequency and location of keywords on a web page, but it can also detect 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.

The fact is that most online businesses and even most webdesign companies do not know a great deal about search engine optimization, it tends to be a separate skill altogether. Unless you have a huge marketing budget and can afford to pay for a lot of advertising, it will help your business massively to understand how SEO works as even knowing the basics will give you an edge over your competitors.

Of course you can hire somebody to take care of the SEO for you, but it wouldn’t hurt to learn a little yourself. There are several steps that will greatly optimize your websites very quickly, but that would require a separate article altogether.
