Case Study: How an Ecommerce Brand Recovered 30% of Wasted Ad Spend and Boosted ROAS

Learn how a high-volume DTC brand used AdPurity to identify a massive click-farm attack and redirected $45,000 in monthly waste back into high-performing human audiences.

For most ecommerce brands scaling in 2026, the primary focus is on "creative testing" and "offer optimization." But what happens when the audience seeing those creatives isn't even human?

In this case study, we look at LuxeWear, a mid-market DTC apparel brand spending $150,000 per month across Meta, Google, and TikTok. Despite having a strong product-market fit, their blended ROAS had been steadily declining for three quarters. Their agency blamed "creative fatigue," but the data in the backend told a different story: high traffic, low engagement, and a surge in abandoned carts from suspicious domains.

By implementing AdPurity, LuxeWear was able to pull back the curtain on a sophisticated fraud operation that was siphoning off nearly a third of their marketing budget.

The Challenge: High Traffic, Zero Intent

LuxeWear was seeing record-breaking "Click-Through Rates" (CTR) on their TikTok Spark Ads and Google Search campaigns. On paper, the campaigns were "winning." However, their Shopify dashboard showed a massive disconnect.

The Red Flags

  • The "Abandoned Cart" Spike: Hundreds of carts were being created daily by users who never entered a shipping address or payment method.
  • Mismatched Geographics: Traffic was spiking during the early morning hours (2 AM to 5 AM) in their target markets.
  • Zero-Second Sessions: Over 40% of the mobile traffic from specific TikTok ad sets was bouncing in under one second.

LuxeWear realized they weren't just experiencing a "bad creative" month. They were being targeted by a Click-to-Earn (CTE) network—a system where real people in low-cost regions are paid to click on ads to help bots bypass basic filters.


The Solution: Real-Time Verification and Pixel Protection

LuxeWear deployed AdPurity across their entire digital ecosystem. The goal was twofold: stop paying for the fake clicks and stop the bots from "training" their ad pixels.

Phase 1: Identifying the Source

Within the first 72 hours, AdPurity’s audit tools identified that 28% of their Google Search traffic was originating from Residential Proxies. These were bots pretending to be users in the United States while actually operating out of offshore server farms.

Phase 2: Automating the Defense

LuxeWear enabled the AdPurity Auto-Blocker. This automatically pushed the malicious IP addresses and device fingerprints to their Google and Meta exclusion lists. More importantly, they integrated the Meta Conversions API (CAPI) through AdPurity. This meant that when a bot triggered an "Add to Cart" event, AdPurity blocked the signal from reaching Meta, preventing the algorithm from optimizing for fake users.

Phase 3: Budget Reallocation

With the automated IP exclusions in place, the "junk" traffic disappeared. This didn't just save money; it freed up $45,000 of their monthly budget that Meta and Google were forced to spend on real human audiences instead.

The Results: A 3.2x Increase in Blended ROAS

The impact of removing the "fraud tax" was felt across the entire funnel within 60 days.

1. Improved Lead and Traffic Quality

The "Zero-Second Sessions" dropped by 92%. The visitors remaining on the site were humans who actually scrolled, viewed product details, and engaged with the brand.

2. Lower Cost Per Customer (CAC)

While the "Cost Per Click" (CPC) rose slightly because they were no longer buying cheap bot clicks, their Customer Acquisition Cost dropped by 30%. They were finally paying for results, not just numbers.

3. Cleaner Retention Data

Because their "Lookalike" audiences were now based on real buyers rather than bots, their retargeting campaigns became significantly more effective. Their email sign-up quality improved, leading to a 15% increase in their email marketing revenue.

Key Takeaways for Ecommerce Growth Leads

LuxeWear’s success offers a clear roadmap for other DTC and Ecommerce brands:

  • Don't Trust Dashboard CTR: A high CTR can often be a sign of a bot attack. If your conversion rate isn't following your click growth, you need an audit.
  • Protect Your Pixel: Your ad platform’s AI is only as good as the data you give it. If you feed it bots, it will find you more bots. Clean your pixel data to see real growth.
  • Focus on Incremental Revenue: The goal of fraud prevention isn't just "blocking." It is the reallocation of that budget into human segments that actually drive LTV.
