When you create placeholders with Ezoic these are potential (temporary) ad locations. Ads won’t display in all these locations at once unless the system has gathered data from the user that demonstrates this is their individual preference. The beauty of the Ezoic system is that instead of picking a location that suits the majority, Ezoic can cater to both people who want an ad in that location and those who don’t by leaving the placeholder in place. Over time the system becomes wise to each user’s preferences from the data collected and adapts ad combinations accordingly.
So when you are are seeing lots of ads, this will not be the same for every user. The reason you as a web owner may be seeing ads in locations you don’t like is for example web owners often spend a long time on the site so the system may categorise you as having a high ad tolerance and show ads in locations you don’t like, because your behaviour on the site differs from how you’d browse as a user. https://www.ezoic.com/many-ads-many-ads-website/
Ezoic has improved ad locations, UX and revenue as a result for thousands of publishers in this way. The longer you give the system, the more data it gathers, and the better it optimises your site for each user. However, if you still have concerns, you can set a max number of ads by following these steps:
