Case study · Portrait · Guyane Automobile
Eight brands, and every lead followed to the sale
One form per brand, used cars in catalogue ads, the CRM connected in real time and a dashboard the team opens every Monday. In twenty-one months, the cost of a lead fell almost threefold.
Renault, Dacia, Kia, BYD, Nissan, Mercedes-Benz, Mazda, Mitsubishi and used cars · GBH group · client since January 2025
The scene
A market where word travels fast
Eight brands under one roof, in a market where word travels fast. A lead nobody calls back never returns. And a budget nobody follows to the sale is spent blind.
At the start, each channel counted on its own: Meta its forms, Google its conversions, the CRM its opportunities. Nobody could say which campaign had sold a car.
How we took it on
One brand, one form, one campaign you can measure
The same €100 note, quarter after quarter: 8 leads in early 2025, 23 in summer 2026.
Kia, Renault, Nissan, Dacia, Mercedes-Benz: each brand has its own account, offers and form.
The stock becomes the ad: 1,624 leads at €1.3 each since January 2026.
Search and Performance Max: +70% test drive, quote and contact requests with 30% less budget, spring on spring.
Every form goes to the right team: new cars, used cars or business.
Since July 2026, every CRM lead and opportunity reaches our data within the minute.
Since February 2026, the brand and used car pages also work without budget.
All the way to the sale
798 website leads, 29 sales traced
Every night, we match CRM sales with the visit that came before them: the channel, the campaign, the keyword. The budget follows what sells.
What the team opens on Monday
An eight-page dashboard, one version of the truth
Advertising, brands, CRM leads, return on investment, sales staff: the Guyane Automobile team reads the same numbers as we do, and asks the assistant its questions.
Spend, leads and sales for the week.
Meta and Google, campaign by campaign.
Each brand, its leads and their cost.
What became of the leads.
Per brand, new and used.
Who called back, who sold.
« We used to count leads. Now we know which ones buy, and we put the budget where it sells. »
What you can take home
Three things that changed everything
A precise offer per brand, and the lead goes straight to the right team.
For used cars, catalogue ads bring the group's cheapest leads.
As long as you cannot see sales, you optimise clicks. Then you optimise cars sold.
