They are important ‘creatures’ in the virtual world, the web spiders; more so in the search engine optimization and search engine marketing industry. What these crawlers do is recognize web pages existing in their database using a particular system, and include them in a web search.

Obtaining new pages, updating existing ones, and deleting obsolete pages are some of the functions they perform. If there has been no linking to the page, then another way to bring a web page to the notice of the crawlers is by sending the site URL to search engine companies and requesting them to include the new page into their search.

The next step is indexing, where the pages are sent to another computer program, where links, keywords, etc. play a major role in identifying the relevancy and the relation of a web page to the search. These are then featured in SERPs.

Some pages, however, do not come up in search engine result pages. They form that part of the web known as the ‘Invisible Web’ or ‘Deep Web’. In a study, the University of California, Berkeley, estimated that the ‘Deep Web’ contained approximately 91,000 terabytes of data and 550 billion individual documents.

One reason this happens is due to pages having random content or it could be irrelevant and badly conceptualized. Another reason is the presence of technical barriers where spiders cannot perform by themselves. For instance, pages where access is granted only by typing manually, member’s only sites, etc.
