How Do Search Engines Work – Welearnio

It is the search engines that finally bring your internet website to the notice of potential customers.

Hence it’s better to understand how these search engines actually work and the way they present information to the customer initiating a search. In this article, We will learn How do search engines work in detail.

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

Search Engines use crawlers or spiders to index websites. Once you submit your web pages to a search engine by completing their required submission page, the search engine crawler will index your entire website. A ‘spider’ is an automatic program that’s travel by the search engine system. Spider visits an internet site, read the content on the particular site, the website’s Meta tags, and also follow the links that the site connects.

The spider then returns all that information back to a central depository, where the information is indexed. It will visit each link you’ve got on your website and index those sites also. Some spiders will only index a particular number of pages on your site, so don’t create a site with 500 pages!

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

A spider is nearly sort of a book where it contains the table of contents, the particular content, and also the links and references for all the websites it finds during its search, and it’s going to index up to 1,000,000 pages each day.

When you ask a search engine to locate information, it’s actually looking through the index which it’s created and not actually searching online. Different search engines produce different rankings because not every search engine uses an equivalent algorithm to look through the indices.

One of the items that a search engine algorithm scans for is the placement and frequency of the keywords on a website page, but it also can detect artificial keyword stuffing or spamdexing. Then the algorithms analyze the way that pages link to other pages within the Web. By checking how pages link to every other, an engine can both determine what a page is about if the keywords of the linked pages are almost like the keywords on the original page.
