lets talk more about this
affiliate offers are where you can earn a commission for selling someone else's product.
not all offers are equal and people have their own preferences for things they want to sell.
once a niche is chosen then it comes to what brand/s to promote and which ones will work. this is a difficult job and one has to bite the bait to find out more. its ok you might lose on the campaign but i will try to get you the maximum value [not the commissions i am sorry about this] that is possible.
my view to approach affiliate offers is to choose a niche test out a product by promoting it
there is more than one way to promote a product. the internet is full of possibilities. if you are successful then of course you have hit the mark. if not successful then this means that you have more work to do. but its not the end of the story if you fail. there a number of other things you can try. keep exploring !
