Hi. I wish you good luck and quick start First of all you have to decide which products would be appropriate to promote with attention to your website users profile; then you can contact several networks to get the highest payment for the products of interest. I am registered in several networks, but, honestly, i am earning the most with Lidango. i recommend to contact them and check their current offers, as they have double commissions for some products.
I would like to suggest you to find you your niche first, then find the best merchant and their support as well as payout history. All the best!!!
I would suggest going to offervault.com, you can see a lot of the networks, their offers and what they pay. A big timesaver and it's free.
try cpalead. you can strat without even having websites. and if you success in a certain niche then you can build a website arround it.
