Freedom Happy New Year to you too! Thank you for your best wishes to us here at the Community team that's really kind of you.
Thank you for your questions, no problem we can help with this, please see the solutions below:
1- I do not have an AdSense account to connect to ezoic. a fix for them
When you have some time we would recommend creating an Adsense account and then linking it to Ezoic. By doing so you can set up mediation and this helps you to be reassured that you aren't leaving any revenue on the table. This support article from Google can help with this: https://support.google.com/adsense/answer/7402253?hl=en-GB
2- Pages without are higher on tablets and desktops, but I do not see how to fix that.
This will be partly down to the volume of traffic that you have and so by increasing traffic to your site overall these scores will level out. To find pages without revenue, follow the steps below:
Click on the ‘Analytics’ tab in your Ezoic account
Click on the ‘Content’ section, then ‘Pages Without Revenue’
Go through each page to ensure there are enough placeholders per page
3- The placeholder variety on tablets is 0; how do I fix that?
Please can you show me where you are seeing this and I'll take a look at this for you?
4- I do not see how to create responsive ads.
