E-commerce Advertising Case Studies

At 82 Marketing, we don’t hide behind vague promises or vanity metrics. We measure our success strictly by the commercial growth and net profit generated for the online stores we partner with.

Below are three real-world case studies demonstrating our strategies in action across Google Ads, Meta Ads, and Performance Max campaigns, highlighting the exact challenges, our strategic approach, and verified performance numbers.

Case Study 1: Dominating the Auto Wheels Market (High-Ticket) in the USA

Industry: Car Wheels & Automotive Accessories (USA) | Primary Channel: Google Ads & Google Shopping

The Challenge: The online automotive wheels market in the United States is fiercely competitive, characterized by high product price points (average order values exceeding $1,200), complex fitment specifications, and intense bidding competition from national retailers. The client needed to achieve rapid sales scale without sacrificing return on ad spend.

Our Approach: We deployed an aggressive Google Ads structure combining brand protection with segmented Performance Max and Standard Shopping campaigns. Through granular product feed optimization, we enriched product titles with vehicle make, model, diameter, and offset specifications. We grouped inventory into margin-based tiers and applied value-based tROAS bidding once conversion volume matured.

The Results: Over a 12-month period, the account achieved remarkable scaling, generating $4.91M in total sales value across 2,940 conversions, while maintaining an extraordinary 1,233% ROAS.

  • Sales Value: $4.91M
  • Conversions: 2.94K
  • ROAS: 1,233%
  • Key Lever: Granular product feed optimization and margin-tiered bidding

Case Study 2: Sustainable Scaling for Men’s Fashion Brand

Industry: Men's Fashion & Apparel (USA) | Primary Channel: Meta Ads (Facebook & Instagram)

The Challenge: A direct-to-consumer men’s apparel store was struggling with rising customer acquisition costs (CPA) and ad fatigue. Previous campaigns relied on broad, unsegmented audiences and static product photos that failed to convey fabric quality and fit.

Our Approach: We completely restructured the Meta account into a disciplined full-funnel system. We introduced Advantage+ Shopping Campaigns for scaling alongside dedicated manual ad sets for lookalike and interest testing. We utilized 82 Marketing Studio to generate dynamic, high-converting video and image assets, testing multiple hooks and consumer pain points. Simultaneously, we implemented server-side Conversions API (CAPI) to ensure complete attribution.

The Results: By eliminating wasted spend on underperforming creatives and optimizing for bottom-line profit, the brand achieved $79.5K in sales value from $22.9K in advertising cost—delivering a healthy 348% ROAS with strong net profitability.

  • Advertising Cost: $22.9K
  • Sales Value: $79.5K
  • ROAS: 348%
  • Key Lever: Full-funnel Advantage+ architecture, CAPI tracking, and rapid creative testing

Case Study 3: Maximum Efficiency in Home & Deco on the Romanian Market

Industry: Home & Deco / Furniture (RO) | Primary Channel: Google Performance Max

The Challenge: An established home decor merchant in Romania sought immediate revenue acceleration heading into a peak promotional window. The objective was to test market demand rapidly and generate fast, profitable sales without weeks of prolonged experimentation.

Our Approach: We executed a rapid two-week sprint focused on Google Performance Max campaigns. We audited historical search queries, eliminated low-converting product listings, and reorganized asset groups around the brand's highest-margin furniture items. We paired high-intent audience signals with localized promotional copy.

The Results: The campaign delivered a phenomenal short-term show of force. In just two weeks, an ad investment of 1.97K RON generated 18.8K RON in sales value—achieving a 955% ROAS (nearly 10x return) and converting cold search traffic into immediate paying customers.

  • Ad Cost: 1.97K RON
  • Sales Value: 18.8K RON
  • ROAS: 955%
  • Timeline: Achieved within two weeks of launch

Our Proven 4-Step Process for Replicating Success

These results are not random flukes; they are the direct product of our repeatable 4-step framework:

1. Audit & Analysis: We analyze historical account data, eliminate budget leaks, and uncover untapped product opportunities.

2. Strategy & Setup: We architect tailored campaigns and implement server-side tracking (GTM, CAPI) for bulletproof measurement.

3. Launch & Optimization: We launch campaigns and monitor performance daily, fine-tuning bids, feeds, and creatives to maximize ROAS.

4. Reporting & Scaling: We review net profit monthly via dedicated dashboards and video calls, systematically scaling winning products.

We operate on flexible monthly contracts with 30 days notice and recommend an initial media budget of at least $1,000 to $1,500/month.

  • Step 1: Audit & Analysis (identifying wasted spend and scaling angles)
  • Step 2: Strategy & Setup (custom campaign build and server-side tracking)
  • Step 3: Launch & Optimization (daily bid and creative adjustments)

Frequently Asked Questions

Can these ROAS figures be guaranteed for my online store?

No ethical marketing agency can guarantee specific ROAS figures, as performance depends on product-market fit, pricing, website conversion rate, and inventory availability. However, our structured process and track record of +50 happy clients and $12M+ generated demonstrate our ability to maximize profitability in diverse niches.

How long does it take to achieve results like these?

Initial traction and performance improvements typically appear within the first 30 days. Full campaign maturity, algorithmic stability, and scalable profit typically develop over months 2 and 3.

What minimum budget is required to work with 82 Marketing?

We recommend an advertising media budget of at least $1,000 to $1,500 per month paid directly to ad platforms. This ensures campaigns generate enough conversion volume for machine learning optimization.
