Case: deferring the consent/CMP + analytics to unblock ad load

Case: deferring the consent/CMP + analytics to unblock ad load

What it did: the CMP and three analytics tags were render-blocking and delaying the first ad request by ~700ms. We async-loaded them and fired ad requests right after consent resolved.

— Setup effort: 3/5 (script ordering + consent-ready hook)
— Outcome: first ad request fired 700ms sooner, above-fold viewability 60% → 73%, page RPM $11.50 → $12.70 (+10.4%)
— Faster ad load = ads rendered before users scrolled past

Pros: the RPM lift came from speed, not new units — pure efficiency.
Cons: must keep consent gating intact; firing ads before consent is a compliance landmine. Order matters.

Lift: ★★★★☆ — Risk: ★★☆☆☆
Verdict: audit what blocks your first ad call — it's often a tag, not the ad. Best for: script-heavy sites. Skip if your TTFB-to-first-ad is already under 1s.
