Click stuffing on open exchange programmatic campaigns
Invalid open exchange publishers inject hidden click interactions into your display placements, inflating CTR metrics and stealing attribution credit from channels that genuinely drove your conversions.

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 invalid 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 invalid open exchange publisher receives credit for a conversion driven by your search campaign, email program, or organic content. Your open exchange channel appears to over-deliver on engagement and attribution while genuinely performing channels are systematically under-credited. Tapper analyzes click signals at the interaction level across your open exchange buy, distinguishing genuine user-initiated clicks from injected or automated events.

Frequently asked questions
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 invalid 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 authorized to sell a publisher's inventory in the open exchange. It does not analyze 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.
