Execution: Created 12 campaign structures with dayparting for peak shopping hours, negative keyword mining across 800+ terms, and bid adjustments based on placement performance (top of search +150%, product pages +75%).

Cross-Platform Case Study #2
TikTok-to-Amazon Funnel Drives $890K in Attributed Sales
Challenge: A beauty brand was spending heavily on TikTok ads but struggled with TikTok Shop's fulfillment limitations and customer concerns about unknown marketplace. Many customers discovered products on TikTok but purchased elsewhere.
01
Awareness on TikTok
Ran aggressive TikTok ad campaigns and creator partnerships driving product awareness and education. Content focused on product benefits, not hard selling to specific marketplace.
02
Consideration Bridge
Added subtle CTA in videos: "Find us on Amazon for Prime shipping" and "Available at Walmart.com." Optimized TikTok Shop listings but removed friction by offering alternatives.
03
Cross-Platform Attribution
Implemented unique discount codes per platform to track customer journey. Used UTM parameters and brand lift studies measuring search term increases on Amazon/Walmart.
04
Conversion Optimization
Ensured Amazon/Walmart listings were perfectly optimized to convert TikTok-sourced traffic. Matching images, benefit messaging, and social proof from TikTok content.

Cross-Platform Case Study #3
Coordinated Product Launch Achieves $1.2M First-Month Sales
Challenge: A home fitness brand was launching their most important product to date—a $299 premium item requiring significant customer education. Single-platform launch risked limiting reach and momentum.
Strategy: Orchestrated simultaneous launch across all three platforms with platform-specific tactics leveraging each marketplace's strengths.
Amazon Strategy
Vine program for 200 early reviews, Lightning Deal at launch, $65K ad spend targeting fitness enthusiasts and competitor ASINs
Walmart Approach
Early access for Pro Seller customers, Walmart Connect awareness campaigns, WFS for fast shipping trust signals

Walmart featured product in curated "New & Notable" collection. TikTok videos garnered 8.2M combined views. Sustained momentum with $520K average monthly sales (months 2-6) across platforms as launch velocity improved organic ranking everywhere.
Cross-Platform Case Study #4
Inventory Optimization Across Platforms Reduces Stockouts 78%
Challenge: A kitchenware brand struggled with inventory allocation across three marketplaces. Frequent stockouts on Amazon while excess inventory sat at Walmart. No unified forecasting system led to $340K in lost sales annually due to availability issues.
1
Unified Forecasting
Implemented inventory management system integrating sales velocity, seasonality, and advertising spend across all platforms to predict demand
2
Dynamic Allocation
Created rules-based allocation: Amazon 50%, Walmart 30%, TikTok 20% as baseline, adjusting based on 30-day velocity trends
3
Cross-Platform Rebalancing
Established process to redirect inventory when one platform exceeded forecasts—transferred 340 units from Walmart to Amazon during Q4 surge
4
Advertising Coordination
Paused advertising on platforms approaching stockout, redirecting budget to platforms with healthy inventory levels
Results: Stockout rate decreased from 23% to 5% across all platforms. Amazon stockout days reduced from 47 to 8 annually. Walmart excess inventory decreased 67%, improving cash flow. Recovered $265K in previously lost sales due to availability improvements. Advertising efficiency improved with coordinated spend—no wasted ad dollars driving traffic to out-of-stock listings. Overall marketplace revenue increased 34% with same inventory investment through optimal allocation.
Cross-Platform Case Study #5
Platform-Specific Pricing Strategy Increases Profit Margin 12%
Challenge: A consumer electronics brand used identical pricing across all marketplaces, failing to account for different fee structures, customer expectations, and competitive dynamics on each platform. This one-size-fits-all approach left money on the table.
Strategy: Developed differentiated pricing strategy recognizing each platform's unique characteristics. Amazon positioned as premium/convenience option. Walmart emphasized value positioning. TikTok leveraged impulse-buy psychology with bundle deals.
Implementation: Amazon: Base price + $3-7 premium justified by Prime shipping and robust reviews. Walmart: Competitive price matching established Walmart.com sellers. TikTok: Psychological pricing ($29.99 vs $30) with exclusive bundle offers creating perceived value.
Results: Overall profit margin increased from 19% to 31% (+12 percentage points) while maintaining competitive positioning on each platform. Amazon pricing premium accepted by 89% of customers due to Prime value proposition. Walmart competitive pricing maintained Buy Box win rate above 90%. TikTok bundle strategy increased average order value by $18. Cross-platform cannibalization minimal—customers self-selected based on shopping preferences (convenience vs. value vs. discovery). Total revenue impact: additional $280K annual profit on $2.1M revenue with no volume loss.
Key Insights
What We Learned Across 25 Case Studies
Advertising ROI Compounds with SEO
Brands that coordinated paid advertising with SEO optimization saw 2.3x better long-term results than ad-only approaches. Initial ad spend improved organic ranking, which reduced future ad dependency—creating a virtuous cycle.
Platform-Specific Strategies Essential

Brands that implemented rigorous A/B testing of images, copy, pricing, and ad creative achieved 67% better performance than those relying on best practices alone. Market dynamics change constantly—continuous testing is non-negotiable.
Cross-Platform Integration Multiplies Results
Unified strategies across marketplaces generated 2.1x revenue compared to siloed approaches. Customers interact with brands across multiple touchpoints—coordinated presence captures more of the customer journey.
