How PIQ scores inventory quality.

Inventory quality measures whether an ad placement is likely to drive performance. PIQ reads 100+ signals on every placement, then values each impression sell-side in the bid stream to optimise towards your desired objective.

Explore PIQ's signals

Quality isn't binary. It's a spectrum.

Every domain gets a PIQ Score from 0 to 100. Quality is a spectrum, not pass or fail, but most of the open web clusters low: we exclude anything under 30 as ad waste by default, then optimise spend up the scale depending on your campaign objective.
