Did you find any improvement in site speed and user interface using ezoic ?
Site speed is a tough one to answer.
Generally speaking, pageloads have been faster. Even on pages where I explicitly don't allow caching! So that's good.
BUT! If I leave my site open in an unused tab for awhile (eg, I open another tab and leave it in the background for a few hours, or if I go to bed and leave it in the main tab), when I come back the tab is unresponsive. I can refresh the page, wait a minute for the browser to give me the option to Exit, then refresh the page and it's fine. Or, I can close the tab and start over in a new tab and it's fine. This has happened with both Chrome and Firefox. No one has complained about that, though, so it might just be me that leaves it open like that.
Income increased by 20-25% but site was combarded by ads. Each page had 6-7 ads which sometimes overlapped content and made it look like a xxx site.
When I let their system automatically do whatever, I had a similar experience but with 15-16 ads! The site was literally unusable, it was just pure trash.
But they have a better option where you can turn all of that nonsense off, create ad units the way you want them, and then manually plug in placeholders where you want ads to show. Those placeholders look like:
<div id="ezoic-pub-ad-placeholder-109"></div>
Once I did that, everything was exactly the way I wanted it. My rep hounds me to plug in more placeholders, etc, but... nah.
I haven't been using them long enough to give a fair review, I figured that I would update in a few months in a new thread. But yesterday my income was up about 50% more than my best day with Ad.plus! If that keeps up, then... yay! :-D
I've definitely confirmed, though, that I make more from Infolinks anchor ad than with Ezoic's or Ad.plus's anchor ad. I had to work with my Ezoic rep to allow the Infolinks tag since they didn't allow it by default.
Also was not comfortable with ezoic taking control over DNS.
Yeah, I definitely didn't like that, either! But what really happens is that, when you create the account, they copy your server's DNS settings to their end and you can still modify whatever you want. And, of course, you can always change your domain's nameserver anytime you want, they don't have control over that.
I understand that their AI system would need access to the page pre-load in order to plug in whatever they wanted. I'm not using that, though, so I don't REALLY see why it's necessary. But I did it and all seems OK, so I'm not losing any more sleep over it.
