Between Q4 2024 and Q2 2026, we analyzed 9.47 billion onsite sessions and 11.62 billion ad impressions across our enterprise customer base, to answer a sharper question than before: not just how much of your traffic and ad spend is real, but how fast that is changing.

Onsite invalid traffic more than doubled to 46.18%, invalid users became the majority, and a 264% rise in self-declared crawlers signals the arrival of AI agents. On the ad side, impression quality held persistent while bot delivery climbed. Inside, you'll find the full seven-quarter trend by channel, the in-ad measurement breakdown, and how fraud0 now helps advertisers recover wasted spend. Download the report to see where you stand.
