Online Marketing

A search engine, such as Google and Yahoo, are tools that allow users to find information on the World Wide Web by searching with a specially designed tool. The results of a search are organized into a list which includes web pages, information about them and links to them. In some cases, it includes images. Search engines are operated algorithmically in conjunction with human editing.

Web crawling, indexing and searching combine in that order to obtain the most accurate results. Mass amounts of information on millions of web sites are stored and then retrieved relevant to the user’s request. A web crawler is also known as a spider, it analyzes every link and indexes all information for faster retrieval.

Mata tags and even words from the webpage are studied to classify the webpage and its content. All these data are stored for future usage.

All the search engines work on more or less the same principle. Google stores the source pages, also called cache, of all the web pages along with information available on the webpage itself. AltaVista differs slightly in operation as it stores everything that a web page has on offer.

Search engine users normally input a keyword or key phrase into the search field. The engine will search for their particular keyword and key phrase on the World Wide Web. The search engine index will provide an organized list of results with the best matched web pages. A short summary of each webpage describing the contents is provided along with the list.

The goal of major search engines is to supply the most relevant results. Not all sites with the requested keywords are relevant to the search. The search engines have used their spiders and indexing to filter out useless information. They generate their own system for analyzing a website for content.

Page rank is latest addition in the techniques used by search engines to sort out various web pages and their contents. Page rank decides the relevance of a particular page by studying the correlation between its meta tags, descriptions, keywords used and the content of that webpage. The search engines rank those sites high that have association with high ranked web pages. The page rank is essential for any web page or site as it determines its probability of featuring at the top of any particular search.
