Carglass®, Semetis, and AdSomeNoise set a goal of increasing the conversion rate by using smart remarketing and media tactics. The team wanted to improve ad relevance and be able to deliver marketing messaging that – both creatively and technically – was as powerful as possible.

In order to provide personalised and relevant experiences to a large audience of users, each with their own individual needs, the team utilised the Google Marketing Platform stack – including Campaign Manager, Display and Video 360, and Studio – and launched a campaign using dynamic creative optimisation.

Carglass® also used Google Analytics 360 in order to gain insights about what information was most relevant to the customer and to get a deeper understanding of website behaviour. Google Tag Manager was important to the project too, ensuring correct tagging and robust data pipelines.

The setup allowed them to run custom experiences at scale in an automated way while keeping control over the quality of the asset.

As a first step, they analysed which parameters were personal to users’ situations and how many users could be mapped to each variable. Damage type and car brand turned out to be the leading parameters.

To remarket to customers who entered the funnel but did not finish, the team served custom banners that included copy relevant to the user’s damage type and car brand. Even the animations were tailored to the user’s specific situation.

The results exceeded all expectations. Compared to previous non-personalised remarketing efforts, the campaign was four times more profitable. For every euro invested, Carglass® received €290 in return.

“Remarketing, especially dynamic creative optimisation, is now a fixed item in our marketing strategy. We took a bold step forward and we were rewarded for our innovative mindset. Our focus now is more on creating the right message for each individual customer instead of getting one generic message across to everyone.”

– Nathan Willekens, Digital Marketer, Carglass® Belgium

Since the success of the campaign, Carglass® been looking for new ways to innovate in their digital marketing. The outstanding metrics have sparked a quest to find better, more relevant and disruptive advertising ideas.

The results have provided serious motivation to the Semetis and AdSomeNoise teams as well. Looking ahead, both are advocating that clients take a personalised approach as the standard, not the exception, and are embedding a dynamic creative optimisation track in the roadmap of all clients going forward.

“We want to push boundaries and use this case as a framework to open this up to more than only remarketing. The use of data within creatives should be a given in any moment of contact, whether the objective is awareness, conversion, or any campaign objective in between.”
