Finding the best product your audience would love to buy has been the greatest headache of internet marketers today. 

because the interest of people divers. so what you think will be good for one maybe a "NO" to another. 

Thats the main reason so many internet marketers are not finding their way out all they think is that the product they are trying to market is not good enough.

 This is a big thorn in the flesh when you cant figure out the best product to market and when you dont find this product you can not make sales and when you dont make sales you dont make profit.
