Banner / Display ad networks: click fraud & invalid traffic
Detect bot traffic and check traffic quality across banner / display networks, with every visit judged Valid or Invalid per campaign and source.
Every banner / display network, judged.
Pick a network for its invalid-share breakdown, tracking tokens and the exact exclusion you can take.
Programmatic display reaches enormous breadth through layers of exchanges and resellers, and that depth is where invalid traffic hides. The format’s economics reward impression and click volume, which creates room for low-quality inventory — made-for-advertising sites, stacked or hidden placements — to absorb spend with little genuine attention behind it.
How fraud works on banner / display.
Where invalid traffic concentrates
Display invalid traffic clusters in a few recognisable structures:
- Made-for-advertising (MFA) sites — pages built primarily to carry ads, often fed by cheap acquired traffic, where the click context looks valid but the audience intent is absent.
- Ad stacking and hidden placements — multiple ads layered in one slot, or units rendered where no human could see them, generating clicks and impressions without genuine exposure.
- Datacenter-sourced click sweeps that hit specific domains or placements in bursts.
Across the programmatic chain the meaningful unit is the placement and the publishing domain, which the supply path can otherwise obscure.
What ValidVisit judges
Three tells dominate display sweeps: server-farm and automation origins, server-side bots that never genuinely load the page, and the traces automated browsers leave behind. ValidVisit captures the outbound domain and the network’s placement tokens on each visit, so the verdict is attributed to the exact domain and placement rather than to a campaign aggregate.
Pinpointing the sub-source
Because programmatic supply chains are deep, the most valuable output is a clean per-domain and per-placement breakdown. ValidVisit surfaces which publishing domains and placements carry concentrated invalid traffic, giving you the evidence to refine inclusion/exclusion lists inside your buying platform — a decision that stays yours to make.
Scoring works the same way on every banner / display network, and ValidVisit only reports: you make each exclusion in the network yourself. How the verdict works →

What is a made-for-advertising (MFA) site and why does it matter?
An MFA site is a page built mainly to host ads, usually fed by cheap acquired visitors. Clicks from it can look technically valid while the audience has no real intent, so it quietly absorbs display budget. ValidVisit judges the visits behind those clicks per domain so the pattern is visible and actionable.
Can ValidVisit see through the programmatic supply chain?
It judges the visit that actually lands on your page — capturing the outbound domain, placement tokens, and 100+ data points across network origin, device, and behaviour — and attributes the result to the specific domain and placement. That gives you ground-truth on which sub-sources are valid, independent of how the impression was bought.
