I do not think there is a general best type of business. i think you should search after the ones which want to develop online marketing for their products, first the ones which are also searched in your geographical area, then the ones which are searched abroad. Also, maybe you should pay attention primarily to the health sector and to the food and ambiental ones. But this is not a rule...What should one do with a cup of coffee if he/she needs an e-book about cars ?
