Click stuffing on open exchange corrupts your attribution model and inflates engagement metrics across the RTB stack
Click stuffing on the open exchange occurs when fraudulent publishers inject hidden click interactions into the display ad placements their inventory serves, registering clicks on your ads without any real user action. The techniques are diverse: hidden iframes that load your tracking URL and fire a click event programmatically, JavaScript click injection triggered at page load or on any page interaction, and stacked ad placements where the visible ad sits on top of your creative. Every one of these injected clicks passes through your standard programmatic tracking chain and appears in your DSP reporting as a genuine user engagement.
For multi-channel advertisers, the attribution damage is particularly severe. An injected click on an open exchange placement can appear as the last touch in a user session before they convert through an entirely different channel. Under last-click attribution, the fraudulent open exchange publisher receives credit for a conversion driven by your search campaign, email programme, or organic content. Your open exchange channel appears to over-deliver on engagement and attribution while genuinely performing channels are systematically under-credited. Tapper analyses click signals at the interaction level across your open exchange buy, distinguishing genuine user-initiated clicks from injected or automated events.

“Tapper's blocking technology purifies our paid media traffic which roughly equates to a 36x return against its subscription costs. It's certainly one of the easiest-to-implement tools in our entire marketing stack.”
Reno Mindemann
Head of Growth, Kama Capital
“We've been using Tapper for over a year now, and it has become a core part of how we run paid media. Invalid traffic was always something we knew existed but couldn't really act on. Tapper changed that. We're now saving up to $50K per year, and on PureSquare specifically, we saw around a 20% decrease in CPA. Based on these results, we decided to roll it out across other ventures under Disrupt as well.”

Frequently asked questions
Everything about click stuffing on Display & Programmatic open exchange.
Open exchange publishers earn revenue per click on ads served through their inventory. Click stuffing lets them inflate their click counts by injecting hidden click events without real user action, extracting additional CPC or CPA revenue while appearing to deliver engagement. Because the clicks pass through standard programmatic tracking, they are indistinguishable from genuine interactions in your DSP reporting without interaction-level analysis.
A stuffed click on an open exchange placement can appear as the last touch in a user session before they convert through organic search, email, or direct navigation. Under last-click attribution, the fraudulent open exchange publisher claims the conversion. Under multi-touch models, the injected click pollutes the attribution path and inflates the apparent contribution of your open exchange channel at the expense of channels that genuinely drove intent.
No. Ads.txt addresses supply chain transparency, confirming which sellers are authorised to sell a publisher's inventory in the open exchange. It does not analyse the quality of click interactions at the event level. A publisher correctly listed in ads.txt can still engage in click stuffing on the inventory they legitimately sell through the exchange.
