Subject of website to earn more trafic..

As with business you got to take one of two approaches... 1. Stick to what you know - this means you will know what to write about and will be able to update it with new information etc as you will know about the subject at hand. OR 2. Gap in the market - harder to get people to start with, but if the idea is unique and something people will want to read then it could get a cult following. Choosing football or cars could cause problems as big news agencies will always be able to beat you for speed, quality and lets be frank quantity of information available on their own websites.

u can make website of any topic.... but the thing is that you should do SEO...
