well because it involves affiliate marketing so better make sure you content is reliable with what you selling to all those audience out there.The Commission Junction model refines this idea such that it is only when an advert results in a deal, not just a click through, that advertisers pay.
No longer is it about numbers of clicks, but conversion which makes into a buy
The platform also allows publishers to choose which adverts to show, assessing the most lucrative advertisers by an "earnings per click" rating.

Publishers like you and me can see which adverts are likely to give the best returns, and judge which ones to take on that basis.so choosing adverts is most important.
i rather compare the CJ programme to a video game.practice only can lead to perfection.
