Fake install fraud and Google Shopping campaigns
Fake install fraud is primarily a mobile app problem, but it intersects with Shopping campaigns when retailers use app deep links in their product listings or run cross-channel attribution that ties Shopping clicks to app install events. Tapper validates app attribution signals tied to Shopping traffic, ensuring your install data reflects real users who discovered your product through genuine Shopping interactions.

Shopping-to-app attribution fraud corrupts cross-channel performance data
Retailers with native apps increasingly use Google Shopping to drive traffic that converts both on mobile web and through app deep links. When a Shopping ad click results in an app install and subsequent in-app purchase, that conversion is attributed across both Shopping and app channels. Fraudsters exploit this cross-channel attribution by injecting fake install signals that claim Shopping traffic credit, inflating the apparent conversion value of Shopping campaigns while delivering no real purchasing users. The result is that Shopping ROAS figures include phantom app conversions, making campaigns appear more efficient than they actually are.
The intersection of Shopping traffic and app attribution also creates an opportunity for click injection fraud, where a fraudulent actor fires a fake click attribution in the moments before a genuine organic app install, stealing cross-channel credit from both the Shopping campaign and the user's real discovery path. For retailers who rely on Shopping as a top-of-funnel channel feeding app downloads, this fraud pattern can completely invalidate the channel attribution data they use to make budget decisions.
How Tapper stops fake installs on Google shopping campaigns
Three steps from connection to clean campaign data, no engineering required.
01
Validate Shopping click-to-install attribution chains
Tapper cross-references Shopping ad click data against app install attribution signals from your MMP. Installs that cannot be matched to a verified real-device ad interaction from your Shopping campaigns are flagged as potentially fraudulent and separated from your genuine cross-channel conversion data.
02
Detect click injection targeting Shopping traffic
Tapper monitors the timing relationship between Shopping ad clicks and subsequent install attributions. Click injection attacks produce statistically impossible click-to-install windows that Tapper identifies automatically, preventing fraudulent actors from claiming Shopping attribution credit for organic installs.
03
Protect cross-channel ROAS reporting
With fake install signals removed from your cross-channel data, your Shopping campaign ROAS reflects only genuine revenue, whether from web conversions or verified app purchases. This gives you accurate data for budget allocation decisions across web and app inventory.

“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimises against cleaner signals and the efficiency comes through quickly. For AMA Nissan, that was a 40% lift in conversion rate and a lower CPA on Google, with nothing else in the setup changing. That is the kind of result we want to offer clients as a matter of course.”

“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 fake installs on Google Ads shopping campaigns.
If your Shopping campaigns are attributed with app install conversions through deep links or cross-channel measurement, fake installs inflate your apparent conversion value. Your Shopping ROAS looks better than it really is, which can cause you to over-invest in Shopping relative to other channels. When the fraud is eventually detected or the inflated metrics normalise, the apparent performance drop can be severe. Tapper prevents this by validating install attribution at the source.
Yes. Tapper integrates directly with major MMPs including AppsFlyer, Adjust, Kochava, Singular, and Branch. When Shopping traffic is part of your cross-channel attribution model, Tapper cross-references the Shopping click data it captures against the install events your MMP records, flagging any attribution claims that cannot be matched to a verified real-device Shopping interaction.
Fake install fraud is most prevalent in pure app install campaigns, but it does affect cross-channel attribution models when Shopping traffic contributes to app download funnels. Retailers with high-volume Shopping campaigns and active app install goals are the most exposed. Tapper provides protection across both the Shopping click layer and the app attribution layer, covering the full conversion path.
