Search Engine

Spread the love

web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are aintained only by human editors, search engines also maintain real-timeinformation by running an algorithm on a web crawler.

LIMITATIONS OF SEARCH ENGINE

Search engines are far from perfect:

  • They rank websites in part according to concepts such as intrinsic authority, which in many cases are flawed, and which allow rankings to be manipulated.
  • They filter results according to the information that a particular user has given them, which rarely provides an accurate reflection of a user’s real interests.
  • Although it is less of a problem than it used to be, search engine rankings have always been manipulated by keyword–stuffing: the inclusion of unnaturally large numbers of search terms into web pages.
  • Rankings are almost certainly affected in some way by the search engine companies’ commercial interests: their dependance on paid advertising, and their promotion of their own products.

Part of the blame falls on the search engines’ users:

  • People who use search engines, and people who own websites, underestimate the vast numbers of individual web pages that often touch on a particular topic.
  • Search engine rankings depend fundamentally upon the search terms that are used. Most users of search engines do not know how to create the most appropriate search terms.Image result for Limitations of Search Engines

Inaccurate Search Engine Rankings

Search engine rankings are frequently inaccurate. In order to understand why they are less than perfect, it is necessary to understand how the rankings are calculated. Search engines attempt to rank websites mainly according to two factors:

  • significance, which can be increased by skilled search engine optimisation,
  • and popularity, which is largely out of the hands of the website’s owner and its designer.

Significant Links to Your Website

Most search engines place great emphasis on the number of significant links to websites, and are able to detect the approximate number and quality of these links. The greater the number of significant links, the more reputable the website will appear to be.

The important criterion is quality, not quantity. Your website’s rankings will gain little or no benefit by attracting links from websites that are unrelated to the material on your own website.

Significance is defined in two ways:

  • Relevance to the topic under discussion;
  • The authority or importance of the website that provides the link.

Relevant Links

Relevance is usually easy to identify, and can often be reduced to the specificity of the words that are used on a particular web page. So, for example, a website for a shop in Crawley, Sussex, will normally gain more benefit by acquiring a link from a website that deals only with the town of Crawley rather than one that deals with the entire county of Sussex.

Authoritative Links

Measuring the authority of a website is much more difficult. Certain websites, such as those of the BBC and the New York Times, are considered by most search engine companies to be authoritative for a large number of topics. A link from one of these websites is both valuable and difficult to acquire.

Many instances of irrelevant search results are due to the imperfect application of the concept of authority. A common complaint is that searches for information about commercial products are rendered useless because of the number of worthless comparison websites that often occupy the first few pages of search results. Although keyword–stuffing is frequently a factor, product comparison websites also seem to be ranked highly because they are considered authoritative.

At the time of writing, Google considers Wikipedia to be authoritative, which is why it often appears at the top of search rankings, even when the Wikipedia page in question is not particularly relevant to the search query. Wikipedia’s bizarre bureaucratic system allows the editing of individual pages to be controlled by cliques or interested parties. Consequently, search results can be deliberately manipulated.

Filter Bubbles: Personalised Search Results

Most web users make little effort to secure their privacy online. Search engines take advantage of this laxity to assemble profiles of each user’s interests. These profiles influence the search results that are displayed to the users.

If you neglect basic online privacy precautions, you are likely to receive search results that match the search engine company’s view of your preferences and interests. Two web users of the same age, in the same city, with the same circle of friends, typing the same search terms at the same time into the same search engine, may well receive two substantially different sets of search results. The difference will be due to the information that the users have given to the search engine company through their past online behavior.
