i will open a blog.. i want to traffic so what is the correct NICHE for that blog? health, politic, General or whatelse what should it be about? Thanks for your help!
you pick a niche that you are familiar with and have interest in. unless you are familiar with the niche and enjoy writing about it, you will not be able to maintain the blog for long and will lose interest quick. so focus on finding what interests you most and go from there. regarding traffic, any niche can bring you the traffic if the right keywords are chosen and the blog is promoted properly
There is no correct niche to choose. As sultanofseo said pick a niche you have an interest in. That way you can provide quality content, some of your knowledge on the subject, your own opinions etc on the niche. The traffic will, if you do your SEO right, start to flow.
I suggest you choose the niche in which you have some experience. Niche, about which you know lot of things and for which, you can write lot of good content. Any Niche about which you are capable of writing content is ok to choose.
You have to choose the niche. The easiest way to drive traffic to your niche site is to buy traffic. If you have the software to mass harvest/email then do that firstly, before adding all of the other ways to drive traffic. I just outsource my traffic to cover all of these methods. getafreelancer.com is a good place to find cheap services.
The only thing I want to add is, the following - is this for profit as a business or for fun? It's an important question because if it is for profit you have to consider the niche you are choosing as well. You may want to factor in how competitive the niche you are targeting is and set some realistic goals for yourself. Also do keyword research and figure out what your potential traffic and income may be. Don't pick a niche that you cannot make money off of. Also I agree with the consensus you have to pick a topic that you know something about and an area that you feel you can contribute interesting content.
