i'm promoting some offers usually email submits but i can't get any profit from it . my last offer has a payout 9$ for DOI . i spent 7$ and get only 15 likes and no clicks . cpc was .50$ ! and from my experience all premium countries have cpc +.50$ ,so how people can make profit with this ? (maybe this type of offers doesn't work for fb ads ?) or should i go with other traffic sources ?
