On the internet there are billions of web pages and hundreds of millions of web surfers. Search engines link those who need information and web masters who want to attract visitors.
Users want to get some information and, taking it into account, take some action (to buy, to download, to comment on something, to register somewhere). Owners of web sites want to attract surfers, their money, attention, actions, opinions.
And these two flows (supply of information and demand for it) happen through the mediation of search engines. Search engines that are worth mentioning can be counted on the fingers of one hand. There may be some peculiarities in different countries, but in general we could name just one Google.
Any other search engine will be more or less similar to Google in its algorithms, approaches and ways of earning money.
Before the internet came into being, people’s decision based on:
- Their own experience.
- Books and other publications.
- TV and radio.
- Rumour mill.
But nowadays the internet is the main source of information. And Google dominates the search engine business all over the world.
So, in a particular country there are hundreds of millions of web surfers and only one search engine. The share of other search engines is usually neglectfully small.
In some countries there may be two prominent search engines. Like in Russia where Yandex has about the same share of search engine traffic ad Google. In China the situation is unique with their Baidu.
Anyway millions of web sites, hundreds of millions of surfers and one or two search engines to coordinate these flows. That is how important they are.
