Does it make sense to alternate advertising platforms?

Question

Monetization

The site is connected to YAN and AdSense. About a week ago, I switched everything to AdSense, the income increased significantly for three days, and then fell back to normal values.
Since 90% of the audience is permanent, there is a suspicion that in three days they saw all the advertising that was interesting to them and stopped clicking on it.
Now I'm thinking about automatically switching ads between YAN and AdSense every two days so that they always have new ads that they haven't seen yet.
Is there any reason?

Answer 1

Test to see if it makes sense for your audience or not. Naturally analyze the results by month. Perhaps one site will fall out according to the results of statistics.

Answer 2

I think it makes sense, I don’t know exactly how Google, Yandex has a curved algorithm for rotating ads, YAN will bother you with the same ads even if you clicked on them 10 times, it’s not clear why Yandex won’t add the function to disable ads after N impressions to one user or after N clicks. And so, as a derectologist will say, you launch YAN after 2-3 days, the CTR drops sharply.

Answer 3

Outcome:
In my case, most likely, it makes no sense. The first 6 days the results were good (growth by 20-25%), then decline below the old results.
So far, I leave only YAN.
