How to monetize content without degrading the user experience?

So i am working on a few content-sites like reviews of products etc.

I want to have a pleasant user experience and therefore i am creating mostly static content with nextjs, lazy loading etc.

What i hate most are pages that erratically jump around after loading. Ads tend to do that and i do not want to expose my audience to this.

Is there some UX friendly provider to monetize content-pages?
