how search engines work


Search engines are the vehicle that drive your website to the attention of your prospective customers. Therefore, it’s critical to understand how search engines work, and how they determine which results the customer initiating a search will see. 


Let’s take a look at how a search engine uses crawlers (spiders). 


Search Engines use spiders to index websites. When you submit your website pages to a search engine by completing 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 operating system. Spiders visit a web site, read the content on the actual site as well as the site’s Meta tags, and visits the links that the site contains. The spider then returns all that information back to a central database where it is stored or 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 try not to create a site with an excessive amount of pages!


Spiders periodically return to previously indexed sites to check for any information that may have changed. The frequency with which this happens is determined by the moderators of each search engine.


A spider is essentially writing a table of contents for the actual content, links, and references it finds during its search. Spiders are capable of indexing up to one million pages per day.


Example:  Yahoo, DuckDuckGo, Bing and Google.


When you ask a search engine to locate information, it is actually searching through the index – not the Web itself. Different search engines produce different rankings because each search engine uses a different algorithm to search through the indices. 


One of the key elements that a search engine algorithm scans for is the frequency and location of keywords on a web page. These algorithms can also detect artificial keyword stuffing or spamdexing. Then the algorithms will analyze how that page links to other pages in the Web. By checking how pages link to each other, an engine can both determine what a page is about, and whether or not it is a valid search result.


Optimizing your website to please these algorithms is a technique known as SEO. Search engine optimization is the practice of strategically using keywords and quality content to tell the search engines that your website is both credible and relevant.
