As every market, the web market is ruled by supply and demand. The major product in demand & supply, is information.

A huge number of web sites compete in attracting the web user’s attention, by offering information or service content of high interest. In the book ‘Economics of Attention’, by Lanham the following is mentioned: the most successful artists and companies are the ones that grab attention and shape it, in other words, that exercise influence. With so much information, simply paying attention is the equivalent of consuming a meal’.

It is like a continuous voting process in which millions of Internet Users vote on the sites which host the most valuable content according to their individual interests. The results appear on the most visited web sites. Moreover web sites ‘vote’ each other by referencing and linking their content to the content of another site. This voting process is very much influencing the search & ranking process of content, by major search portals. A content that is ‘voted’ by other sites of high quality, is considered of high quality (also called high link popularity). Some sites have tried to develop artificially high link popularity, in order to receive high search engine rankings. This is part of what is called web spam, a problem of increasing severity to the search engines.

The higher the demand for this content, the more visitors are attracted. The more visitors & clicks, the more attractive the site becomes for those interested to advertise relevant to the content products & services. Because advertisement revenue becomes an increasing part of the revenue structure of many portals.

This rivalry becomes more and more intense, as information floods the Internet (infoglut). The identification of valuable information to the user and the ‘relevance ranking’ is almost impossible to be done manually, even if the user spends a lot of time reviewing material. This is why the role of the Big 3 search engines has become so central on the Internet. The ability of a site to appear in the top 10 list of a search, very much affects its chance of being visited by a user looking for a specific information. A page’s Google Pagerank is like a maturity and acceptance ranking, which affects substantially its ability to appear ahead of other pages in search results.

As soon as a portal manages to attract a User, the aim is to keep him on the site as long as possible in order to maximize the user exposure to the material advertised. Therefore info is frequently presented in small chunks and cannot be downloaded in one piece.

The more specialized the content they present, the more specific the target group they aim at. The ability to tackle a specialized subject (e.g. food recipes) can attract advertisement from market players on this area (food & beverage providers).

New market makers appear (offering search engine optimization services, automated software for domain submission to numerous search engines, search marketers, web affiliate programs promoters, mail marketing etc), which offer to increase the revenue potential of a web site. Sometimes the extreme use of such services may lead to the opposite result. There is no substitute for quality content.
