I myself use Adsense in sticky sidebar for years and didn’t get a single issue. Sticky sidebar is just a sidebar moves along content. there is no violation in that
@Duggu What you say?
There are thousands of the website - which are doing the same but their own risks
no one should do this its against the Google policy as all are know that.
They are using Google ads manager to serve AdSense ads. You can also use it to create sticky ads.
Adsense does not allow sticky ads, but you can use ad manager to do it.
