The Obstacles
The agency was managing a Specialized Household Bio-Enzymatic Cleaning Business that had a great product but a "leaky" online store. While the brand had successfully validated its market, the agency was struggling to scale their ad spend because the low average order value (AOV) and poor website conversion rate made customer acquisition too expensive.
The agency team didn't have the internal specialized bandwidth to perform a technical deep-dive into the user experience or build out a complex backend retention system. They needed an invisible partner to step in, identify exactly where the revenue was being lost, and install the growth foundations required to turn the account into a high-scale winner.
The Strategy
I plugged into the agency as their "stealth" optimization specialist to execute a comprehensive conversion overhaul. I focused on the three primary pillars of e-commerce growth—Conversion Rate, AOV, and Lifetime Value—without requiring any management from the agency’s internal team:
The Leak Detection Audit: I conducted a full-site audit to find "revenue leaks." I identified critical friction points in the mobile UX and the checkout flow that were causing potential customers to drop off at the last second.
Persuasive Messaging Overhaul: I rewrote the core product descriptions and landing page copy to focus on high-persuasion triggers, moving the brand away from "commodity" language to "must-have" solution language.
AOV Engineering: I designed and implemented a new bundling and "upsell" strategy. By strategically grouping products, we encouraged customers to buy more per transaction, which immediately made the agency’s paid traffic more profitable.
Backend Retention Automation: I built an automated email sequence to handle the "heavy lifting" of repeat purchases. This ensured that once a customer was acquired, they were put into a system designed to increase their lifetime value on autopilot.
The Results
By handling the technical diagnostics and strategy as a silent partner, I delivered a massive performance lift that allowed the agency to scale the client's budget aggressively:
215% Increase in Conversion Rate: The site began converting traffic at more than double the previous rate almost immediately after the mobile and cart fixes were deployed.
115% Lift in Average Order Value: By implementing the new bundling strategy, the revenue earned from every single customer more than doubled.
$125k Monthly Revenue Growth: I helped the agency grow the account from $30k per month to over $155k in monthly revenue.
Plug-and-Play Partnership: The agency took full credit for the growth foundations, transforming a "stagnant" account into a flagship case study while I managed the entire optimization process behind the scenes.
