Internet is a huge collection of the various sources of information. The job of the search engines is to give the users the most relevant results when a search term is entered into the search box. The technique used to make a site the most relevant so that it displays in the first few pages of SERP is called search engines optimisation. 


A big point to note here is the world is very large and comprises of different countries speaking different languages and following different culture. This makes it important to have more than one search engine which can be specific to each country and give the most relevant results.

Just imagine a situation where Chinese receive information in Hindi. Of course it will be of no use to them and so search engines make no sense to them. One more usefulness of country specific search engines is the results are not only relevant but also language specific. Hence it is important to rank in country specific search engines.

The irony of SEO is it is never certain what efforts can get you to the first page. Often it might happen you have all the things needed for a good ranking in place but still your site ranking is not improved. One reason for this can be your site hosting. It is quite possible that you wish to rank for a particular country while your site would be hosted on some other country.

Search engines can determine the nationality of a website based on the IP address as well as the domain extensions like .co.uk or .com.au. For example if you have a site with .co.uk and wish to rank good in Google in USA then this might not be quite possible. However if you shift your host from UK to USA your chances to rank become brighter.  Different tools can be used to know the nationality of a site and do the optimisation accordingly.
