<b>The unwritten ad-density line nobody tells you</b>
There's no hard 'max ads per page' anymore — but there IS a 'content must exceed ads' rule. Short pages with 4 units = trouble.
My rule of thumb: at least 250 words of real content between any two in-content units, and ads never more than ~30% of vertical screen space on mobile.
— stopped getting 'better ads standards' warnings
— RPM untouched
It's about ratio, not count. Test it on one page first.
