Just Kampers

Parts. Passion. Performance.
Just Kampers are a household name in the VW community, supplying parts and accessories for both classic and modern Volkswagens. But even the best brands can hit a wall.

Traffic was tanking. Their Cost Per Acquisition (CPA) was climbing fast. Google was ignoring hundreds of subcategory pages. And they weren’t willing to throw more ad spend at a leaky funnel. They needed a fix that didn’t just look good on a report, it had to shift the numbers that mattered.

Just Kampers had two big challenges:

Crippling SEO Issues

Hundreds of category pages were too similar, so Google wouldn’t index them. Traffic nose-dived.

Escalating Paid Search Costs

They wanted to cut Cost Per Acquisition (CPA) without losing conversions.

Our approach

Most of their subcategory pages were just too similar. Google had stopped indexing them, and organic traffic had nose-dived.

 

So we got to work. Using our in-house LLM (Large Language Model), we generated unique, semantically rich content for over 600 subcategories. Then the Just Kampers team layered on their brand knowledge, the human touch that makes the difference.

 

Result? Google started indexing again. Traffic bounced back. And they owned their long-tail keywords.

AI-Powered Content That Google Couldn’t Ignore

A Conversion Process Built for Growth

We didn’t just patch things, we rebuilt the journey.

From product pages to checkout, we stripped out friction, confusion, and dead-ends. Every change was tested. Nothing rolled out unless it improved performance.

 

The payoff?
A clean, fast, conversion machine, delivering a 22x return on our CRO work.

Paid Search: Smarter, Leaner, Stronger

Their ad account was bloated with underperforming keywords. We sliced through the fat.

  • Cut spend on clicks that never converted

  • Doubled down on high-performing terms

  • Refined targeting and landing pages for every stage of the funnel

 

Outcome:
CPA dropped by 52%. Conversions climbed by 25%. More bang. Less buck.

The Impact

We didn’t just improve a few metrics. We turned things around:

+25% monthly organic clicks

£250k annual revenue recovered

52% lower CPA

212% total revenue bump

22x ROI on CRO
