Stop invalid traffic on open exchange programmatic

The open exchange RTB auction model processes bids at millisecond speed using self-declared publisher information. There is no real-time independent verification of the declared domain, traffic source, or audience quality at auction time. Any buyer with DSP access can bid on open exchange inventory, and any seller with SSP access can list inventory, creating a very low barrier to entry for bad actors. The combination of speed, scale, and minimal gatekeeping makes open exchange the primary target for invalid traffic operations.

The most prevalent invalid traffic types on the open exchange are domain spoofing, bot traffic (both GIVT and SIVT), click farms, and click stuffing. Domain spoofing misrepresents which publisher's inventory is being sold. Bot traffic inflates impression counts with non-human traffic. Click farms use real devices to generate invalid engagement. Click stuffing injects hidden interactions to steal attribution credit. These invalid traffic types often operate together through the same invalid publishers.

DSPs apply basic invalid traffic filters, including known bot lists and some domain verification, but these are general measures that catch straightforward invalid traffic. They are not designed to detect sophisticated invalid traffic types such as residential proxy networks, real-device click farms, or click stuffing. DSPs also have a commercial interest in delivering impressions, which creates a structural tension with aggressive traffic filtering. Dedicated protection like Tapper operates independently of that commercial dynamic.

Tapper integrates with the major demand-side platforms, including DV360, The Trade Desk, Xandr, and custom ad server setups. Our team can advise on the best integration path for your specific programmatic stack and inventory mix.

Most advertisers see measurable reduction in invalid traffic rates within the first campaign cycle after deployment. As suppression lists are built from your specific buying patterns, invalid traffic exposure typically declines further over subsequent campaigns. Tapper provides ongoing reporting so you can track invalid traffic rates and clean traffic delivery across your open exchange inventory.

Open exchange inventory can deliver real scale and cost efficiency for brand awareness and prospecting campaigns when invalid traffic is actively filtered. The problem is not the open exchange itself but the absence of independent traffic-quality monitoring that most advertisers currently operate without. With Tapper in place, open exchange buying delivers the reach you are paying for rather than the reach your DSP reports.
