asoz In my case, the combination of Ezoic and Adsense was greater than Adsense alone. Also, after a period of time, Adsense began paying more than it had prior to my joining Ezoic. More competition for the ad spots, I was told.
The only negative that I've come across is that since Adsense requires a minimum of $100 in revenue before they send payouts, while Ezoic will payout after $20 or so, there could be a wait for the income from Adsense. In the short term, because you might have to wait a month or two to see an Adsense payment (if your traffic is low), it can feel like the income has decreased when the reality is that it has increased over the long term. You just get paid monthly for part of it and however long it takes to meet $100 minimum for the Adsense portion.
Of course, if your Adsense income is already above $100/month, this is not an issue.
