Pulling up an Internet search might be second nature to you by now. But a little forethought into where you begin your hunt can make your life much easier. Eventually, though, over the course of the decade of the s, Google rose to prominence as the undisputed premier search engine on the Internet.

To a large extent, this was due to the level of integration that Google was able to achieve in its operations: Google provided not only a search service but also, over time, an advertising service, an e-mail service, a video service, a scholarly database, and a virtual library. Google also offered the option of stratifying searches according to genre e. By now in the year , the suggestion can surely be made that although other search engines most notably Yahoo still continue to exist, it is safe to conclude that in the minds of most people, the technology of the search engine itself has become indissociably connected with Google.

Indeed, this is reflected in the fact that "Google" itself has by now become an English verb i. In order to access any requested information from the Internet and provide it to the user in a matter of a fraction of a second, the search engine must, first of all, develop a comprehensive index of all the material available on the Internet.

As Moz has written:. Each stop is a unique document. The search engines need a way to 'crawl' the entire city and find all stops on the way, so they use the best path available—links" 2. The robots used by the search engine, often called crawlers or spiders, serve the purpose of mapping out all of the relevant interactions of the Internet through the link structure. It is this structure that is utilized when a given Internet user posts a search query to the search engine.

The main key for navigating the link structure is the algorithm. As Google itself has indicated:. The more sophisticated the algorithms involved, the more likely it is that the results provided for a given search query will be salient and meaningfully address the needs of the Internet user Mostafa. By these times, most people perhaps almost take for granted as a fact that Google will almost always provide one with the actual information that one is looking for.

This was not, however, always the case: One of the primary metrics used by a modern search engine such as Google when retrieving and sorting information is relevance. This would seem to be straightforward enough. As Moz has pointed out, though:. Today, hundreds of factors influence relevance" 3. In general, relevance for search engines has come to mean a broad metric pertaining to the quality of the web pages retrieved; and this is for the simple reason that if a web page is of low quality, then the information it contains likely will not be relevant for the Internet user, even in the event that the words on the web page technically match up with the words of the search query.

Therefore, one of the key purposes of the algorithms utilized by a modern search engine is to evaluate the quality of a retrieved webpage. This is often done by considering the extent to which a given webpage is formatted accord to generally accepted quality standards, the extent to which it is linked to other webpages on the Internet, and so on Enge. Now, in order to further understand how a search engine such as Google operates, it is necessary to consider a question that seems obvious but very profound at the some time: People generally experience the Internet as a virtual cloud that is everywhere and nowhere at the same time.

And yet, the Internet must have some material basis in the physical world. This is part of why and how, for example, it is even possible for individual nations to attempt to censor the Internet.

The fact of the matter is that the Internet is "stored" in immense data computers around the world. When an individual Internet user types a search query into Google, he is essentially linking up his own computer with these data computers: This material basis of the Internet is in fact quite immense, consisting as it does of enormous computers that lack screens but have additional processors in order to fulfill their specified tasks. As Glanz has written:.

Online companies typically run their facilities at maximum capacity around the clock, whatever the demand" paragraph 7. In any event, the main point for present purposes is that a company such as Google has its own vast stores of these data computers. The indexed Internet is contained within these computers, and the specific links accessed by a given Internet user are in fact stored in the form of data within these computers, whether owned by Google or some other stakeholder who produces content for the Internet.

The emergence of the Internet in general and search engines in particular has had a very important implication for businesses around the world.

This implication can be summarized with the term of search engine optimization.
