There are some sites that have a revenue-sharing model with the writers or content providers through clicks on the advertisement managed by them on various internet sites but Google Adsense is the biggest among them in regards to the number of members as well as the number of sites where it operates. It is highly reputed and has an excellent history of providing shared advertising revenue to its members. It is of course sad to note that the amount of revenue that used to be there earlier is dwindling with time and only when views are in good numbers one can expect a payout from Adsense.
There are many other such sites as - Media, PropellerAds, Monumetric, Revcontent, Adversal, Mediavine, Bidvertiser, SHE Media, Taboola, ylliX, RevenueHits, Adcash, BuySellAds, Skimlinks, Amazon Native Shopping Ads, Sovrn //Commerce, PopCash, Setupad, AdRecover, PopAds etc.
One can go to these sites and find out their salient features. Some sites are more useful for a particular type of advertising campaign while some are good for blogs. At the same time, some are more inclined to affiliate marketing while others are good for new publishers. So, one can find the details about them and choose one as per one's need and liking.
Knowledge is power.
