Ad-driven CLS

The challenge

A high-traffic content network ran static floors set two years earlier and a bloated 14-bidder client-side wrapper. CPMs had eroded under first-price bid shading, pages were slow, and the team had no holdout measurement to know what was actually working.

What we did

Connected both GAM networks to the PubMonetX console and ingested 30 days of auction logs to build a bid-landscape baseline.
Activated AI floors in shadow mode across geo × device × ad unit segments, then promoted rules that beat the 5% holdout for 14 consecutive days.
Pruned the wrapper from 14 to 8 client-side bidders, moved the long tail to Prebid Server, and tuned timeouts per geo.
Rebuilt the article template's slot reservation CSS, eliminating ad-driven CLS entirely.

“The holdout reporting was the difference. For the first time we could see exactly what the floors were earning us — not a vendor's slide, our own control group.”
