<b>Ad density: tuning words-per-ad</b>

<b>Ad density: tuning words-per-ad</b>

What it does: sets how much content sits between in-content ad slots. Too dense = policy risk + UX rot; too sparse = left money on the table.

Setup effort: 2/5 — most in-content injectors take a 'min words between ads' param.

RPM lift seen: the sweet spot is usually 1 ad per 250-400 words. Tightening from 600 to 350 words/ad often adds +12 to +20% page RPM before diminishing returns hit.

Pros
— Direct, predictable revenue lever
— Easy to A/B by section

Cons
— Past ~1 ad/200 words you trigger Google's 'more ads than content' policy risk
— Hurts dwell and return visits if it feels like a slideshow

Verdict: target 300 words/ad, never go below 200, and exempt the intro. Lift: ★★★★☆ — Risk: ★★★☆☆
Best for: long editorial. Skip aggressive density on thin or affiliate-review pages where trust = conversions.
