Seven figures added. No extra ad spend.
After expanding their course catalogue without updating the site to match, HPA had hit the wall every scaling brand hits: more ad spend, same conversion rate, no compounding. Customer research found the actual motivation. Eighteen months of testing rolled it through every page. Seven figures added. Same ad spend.
The problem we walked into
HPA had built a strong business teaching tuning and engineering to the aftermarket automotive industry, with over 100,000 students across 175 countries already through the courses. The fundamentals were there.
But they’d expanded their course catalogue without evolving the website or the messaging to match. Previous testing efforts had, in their words, humbled them. They needed to move from random experimentation to a system that compounded.
The research that unlocked it
We spent four weeks on discovery, running on-site surveys, email surveys, analytics funnel analysis, heatmap review, session recordings, and user testing all at once. Six methods. One question: why do these buyers actually buy?
The insight that mattered: buyers weren’t motivated by features. They wanted to do the job the right way. Three purchase drivers came out of the research (self-improvement, specific project builds, career development), and the homepage spoke to none of them directly.
Test 1: Homepage hero rewrite
We reframed the hero around the core motivation we’d found in research. Variants like “Learn how to build cars the right way” and “Build your project car the right way” replaced the feature-led original.
The winning variation lifted purchases from new visitors by 69% and add-to-carts by 36%. From there the messaging rolled straight into paid ads and email, pulling the same insight through the whole funnel.
Test 2: Checkout friction removal
Customers had to sign up before they could buy. That friction was costing the team. We engineered a checkout that required only name and email at the start, keeping the login flow for returning customers.
The variation shipped at 99% confidence with an 8% lift across every checkout visitor, which on its own projected to over $300k a year.
The program that kept paying
We scaled the testing cadence from zero to between five and ten live tests a month. Research kept feeding new hypotheses into the ICE-L prioritisation queue. Wins stayed live. Losses got documented.
180 tests in 18 months, at a 35% win rate (roughly double the industry typical), with single wins bringing in six figures of additional revenue. None of it required an extra dollar of paid media.
What compounds harder than the numbers
The bigger shift is cultural. HPA’s marketing team doesn’t argue about ideas in meetings any more. They test them. Decisions that used to take weeks now take a sprint.
That’s the part we care about most. The tests pay for the program. The culture pays forever.
What actually moved
- Homepage messaging rewrite drove 69% more new-visitor purchases and 36% more add-to-carts.
- Checkout friction removal shipped at 99% confidence with an 8% lift, projected $300k+/year.
- Insight from research rolled into paid ads, email, and product page copy.
- Testing cadence scaled from zero to 5-10 live experiments a month.
- 35% win rate across 180 shipped experiments.
“Working with Impact Conversion has been epic. We’ve seen single wins that brought in six figures of additional revenue, which makes the ROI a no-brainer. Beyond the numbers, the testing process has instilled a culture of experimentation within our marketing team which has removed assumptions and helped us make better decisions.”
