Brands didn't want traffic. They wanted customers.

How Carmate went from a new-car catalogue to a lead-generation business, and the decisions along the way.

01  Context

The market turned to new cars

In 2024 it became clear that Cambodia's car market was moving from used cars to new ones. Carmate had been built for used cars: a simple listing, posted and browsed. New cars needed something else entirely: a catalogue of every official brand, model, year and trim, with prices people could trust.

I designed that catalogue from the data structure up. It's a story of its own.

02  Version one

Complete, but just a catalogue

Local staff filled in the catalogue while I built the website around it. When it went live, two things were wrong:

aThe only thing a buyer could do was call the brand.
bNothing measured what we sent brands, so we had no way to show our value.
03  Seller Central MVP

Give each side what it needs

Buyers in Cambodia want to see real cars in stock and the current promotions. Brands need proof that people are coming. So I designed Seller Central as an MVP: brands post in-stock cars and promotions, and see daily visitors, impressions, views and clicks on every button across their models, listings and promotions.

04  What brands said

A great response, and the wrong question

From mid-March 2026 I took a presentation to several official brands. The response was better than I expected:

+The first tool that showed their performance beyond paid Facebook posts.
+Promotions stay visible for the whole promotion period instead of vanishing in a feed.
+Nowhere else in Cambodia has reliable, current prices.
+A buyer who searched and compared prices is a different customer from someone who clicked a Facebook ad.

Then two problems. They measured our traffic against the couple of hundred thousand people their Facebook ads reach. And every meeting came back to one question: “So how many customers can you bring us?”

05  The insight

“Brands don't buy traffic. They buy customers.”

I had seen this before. Used-car dealers who ignored our calls became very responsive the moment we brought a buyer to their shop. Official brands were no different.

06  The decision

Turn the catalogue into a lead engine

Push for more trafficFor: It's what brands already understandAgainst: We would lose to Facebook's reach every timeRejected
Capture buyer enquiriesFor: Answers “how many customers?” directlyAgainst: We have to earn real demand, not just visitsChosen

In April 2026 I started the redesign. Check Offers and test-drive forms went onto every model, listing and promotion. Seller Central was rebuilt around leads. Traffic charts moved to the back, and the monthly brand report now shows leads and which parts of the site brought them in.

Getting that redesign launched is case study 02.

07  Honest numbers

A smaller number I could stand behind

To show which part of the site triggered each enquiry, I started tracking every element. That exposed scrapers: automated visits inflating our numbers. I took them out of every report, even though our figures got smaller.

~11,600Automated sessions removed
32,831 → 21,360Brand-page visits, before and after

A report that holds up when a brand checks it is worth more than a bigger one that doesn't.

08  Where it stands

Real demand, and the next problem

~1.5 / dayOrganic buyer leads
$0Paid marketing spend
138Leads in 90 days
41 of 1,049Check Offers presses that became a lead

No brand has signed yet. The lead data is what I'm taking back to them, as a month-by-month story of what Carmate sends each brand.

The next problem is already clear: 1,049 people pressed Check Offers and 41 finished the form. I've added tracking to find where the rest drop off.

09  In hindsight

What I'd do differently

I'd put a lead form in front of brands before building traffic dashboards. “How many customers can you bring?” was the real question all along. Asking it in the first meeting would have saved a round of building.

Next — Case study 02The launch date was fixed. Half the platform wasn't connected.
