How it decides

IAS uses its Threat Lab and associated research efforts to identify ad fraud instances and trends at large to inform its fraud definitions and blocking practices.

DoubleVerify uses an MRC accredited metric called an “Authentic Impressions” as the core of its reports, and its blocking and targeting efforts center on maximizing this metric.

Daypart utilizes only client performance information to optimize its blocking systems and does not rely on any external accrediting bodies.

What it covers

IAS and DoubleVerify cover a vast amount of different platforms and many DSPs, being built in the era of programmatic platform and ad network proliferation.

Daypart is focused on a smaller number of channels, notably Meta Ads and Google Ads, that have become dominant in recent years.
