I did a review of Ezoic back in 2017 which, ultimately, made clear just how effective a form of advertising they are, in the sense they can, at the minimum, double earnings of, pretty much, any website out there. For my own website PoemAnalysis.com, earnings increased by 160% as compared to Adsense.
For those that are using Adsense, you are mad to not try Ezoic, seriously. If you still are not convinced, here are 3 reasons that every website that runs PPC adverts needs to start using Ezoic.
 

#1 Increased Earnings

Ezoic claims that the majority of websites that use Ezoic see an increase in their earnings from 100-300%. Therefore, why would you not want to try a program that has the potential to double the value of your website as easily as that?
 

#2 Greater Flexibility

An inherent problem with Google Adsense comes with the restrictions. There are many things you can do with the adverts, such as change locations, colours, sizes and more. However, there are probably even more things you are told by Google you cannot do with the adverts, otherwise you would put yourself in jeopardy of being banned.
Ezoic is a certified Adsense partner, which means they are in the Adsense ‘network’ whilst the restrictions to normal publishers do not necessarily apply to them. This means the limit of three adverts on a web page does not apply, having adverts stuck fixed to the sidebar does not apply and more. You can better match your adverts to the website you have for increased earnings.
 

#3 Improved Website Health

By far the biggest reason, in my opinion, to try Ezoic is the fact that I can prove it actually improves your website health too – it’s mad I know. However, I’ll explain everything below.
With PoemAnalysis.com, adverts from Ezoic stopped appearing due an error that occurred when the SSL certificate of the website was being renewed. It actually took me a few days to realize that earnings had dropped to zero (since no adverts were being displayed by Ezoic). However, after talking to the friendly support of Ezoic, we got everything back up and running to as it was beforehand.
The interesting point to this conversation is seeing, in Google Analytics, just how much having all of Ezoic’s adverts removed from my website affected the earnings of it. See the below images:

The pages/session fluctuated a lot more when Ezoic was disabled, where the average was less than when Ezoic was enabled. It is most clear with the bounce rate, where it would be around 25% when Ezoic was enabled as opposed to around 80% when it was not enabled.
This seems counter intuative that displaying adverts on a website can help make a website better, especially with the bounce rate. But, remember that Ezoic uses machine learning. For all we know, having adverts on a website might help to entice the web user into staying on the website? Either way, Ezoic guarantees results with the artificial intelligence machine learning it uses.
