Ouestfrance-auto.com and ZoomCar used iovox dedicated numbers to create a transparent, data-driven pay-per-lead model that made their platform's value undeniable to automotive advertisers.

As part of the Additi Media group, Ouestfrance-auto.com and ZoomCar are French automotive industry leaders facilitating vehicle sales from professional clients to online shoppers. Demonstrating platform value to advertisers regularly is critical, particularly since car buyers often phone before purchasing and advertisers pay per valid call.
The company needed to clearly demonstrate their platform's value to clients through transparent, timely, and accurate data regarding phone calls from potential car buyers. Without this, billing was difficult to validate and the commercial case for continued advertiser investment was harder to make.
Ouest-France implemented iovox Dedicated Numbers paired with analytics tools to create a pay-per-lead model with full attribution. Each number was tied to a specific vehicle listing or advertiser, so every call could be tracked back to the exact ad that generated it.
They also began piloting WebConnect, which strategically places call buttons across their websites to gather more comprehensive call data, including which vehicles visitors were viewing when they decided to call.
"The transparency and objectivity of the call data made it perfectly clear for our customers to understand the value we bring them."
Dedicated call tracking provided complete attribution, enabling Ouest-France and ZoomCar to validate billing and demonstrate traffic volume to advertisers. The data revealed purchasing patterns including average prices, sought-after brands and popular vehicle years, giving both the commercial team and their advertiser clients genuinely useful market intelligence.
For advertisers, the transparency of call data made it straightforward to understand the return on their platform investment.
