Malvertising & Ad Quality Index Q1 2021

(formerly known as Demand Quality Report)

Download full report

Confiant's Malvertising and Ad Quality (MAQ) Index (formerly known as our Demand Quality Report) is a quarterly look into the quality of demand in digital advertising.

Using a sample of over 180 billion impressions monitored in real time in Q1 2021, Confiant is able to answer fundamental questions about the state of ad quality in the industry at large.

Digital advertising delivers significant value to publishers but introduces myriad risks related to security, privacy, and user experience. Malicious, disruptive, and annoying ads degrade user experience and drive adoption of ad blockers.

In September 2018, Confiant released the industry's first benchmark report.
This report, the twelfth in the series, covers Q1 2021.

It’s also crucial to understand how long threats persist on an SSP once an attack is underway. We measure how long it takes from when a threat first appears on an SSP to when it’s last seen. On this measure, we see huge differences among the major SSPs.

In Q1, SSP-M’s average response time remained quite elevated at 84 days. Unlike last quarter, no SSP achieved average response times of 1 day or less, and many issues persisted for multiple weeks before being resolved.
