Sophisticated invalid traffic has outpaced the filters built to catch it. This report maps where detection actually stands and where the gap sits.
The detection gap
Network-side filtering is tuned to protect the network's own quality score, not your budget. It catches the crude and passes the sophisticated, and it never shows you the boundary between the two.
What is inside
- Detection method comparison — signature, heuristic, behavioral, and identity-graph approaches
- Where each method fails against agentic and proxy-laundered traffic
- Integrity metrics worth instrumenting on your side of the transaction
- What independent verification adds that platform filtering structurally cannot
Why independence matters
A party that sells the click cannot be the party that grades the click. Everything else in this report follows from that sentence.
Frequently asked questions
Why doesn't ad network filtering catch sophisticated invalid traffic?
It's tuned to protect the network's own quality score, not your budget. It catches the obvious cases and lets the sophisticated ones through.
Why does independent verification matter?
The party that sells the click can't be the party that grades it.
