Overview

Maximizing return on advertising investment represents a major challenge for companies operating in the financial sector, where strict rules and product sophistication complicate the implementation of effective promotional tactics.

In fact, conventional advertising campaigns struggle to achieve their objectives, distinguished by exorbitant acquisition costs and limited ad personalization. However, the advent of dynamic ads powered by artificial intelligence opens up a tantalizing opportunity to improve the impact of marketing strategies 

The company and its initial challenges

A medium-sized online bank was facing major challenges, with a stagnant return on advertising investment (ROAS) of €2.5 earned for every euro spent, a click-through rate (CTR) below 0.8% for its display campaigns, and a high cost per acquisition (CPA) of €45 per new customer.  

 

Clearly, these boundaries reveal a lack of flexibility in the face of a rapidly changing digital marketplace.   

What strategy could be envisaged to optimally integrate dynamic advertising generated by artificial intelligence?

To meet these challenges, the bank has deployed a futuristic strategy based on artificial intelligence:

 

 

Case in point: the use of AI for targeting makes it possible to create campaigns tailored to regional preferences or seasonal events such as Christmas or Easter, Nespresso has thus increased its click-through rates by 25% thanks to personalization based on purchasing behaviors analyzed via its digital channels.

 

Tools used :

Advertising AI platform for predictive analysis (e.g. Google Vertex AI).

Customer data management system (CDP) enriched by machine learning.

2.Cross-team collaboration: Integration of commercial feedback into AI models.  

 

3.Adapted tools: Use of Google Cloud for predictive analysis and campaign management. 

 

4.Culture of experimentation: Monthly tests on 15% of the advertising budget to refine algorithms.  

 

Lessons learned and futurs prospects

Key lessons :

  • AI requires initial investment in training and infrastructure.
  • Algorithm transparency is crucial to maintaining customer confidence.

 

Future applications :

  • Generative chatbots for personalized financial advice (e.g. Bank of America's Erica).
  • Trend prediction via social network analysis (e.g. Safe Rate's “Beat this Rate” tool).
  • According to Jacobo Roa-Vicens (JP Morgan), “AI and blockchain will redefine customer interaction in finance.”

 

    Conclusion

    The integration of AI into dynamic advertising has enabled our bank to increase its ROAS tenfold, while reducing costs. For players in the financial sector, ignoring this revolution is tantamount to risking obsolescence.  

     

    As demonstrated by the success of Nubank (85 million customers), the future of financial marketing belongs to those who know how to combine technological innovation and customer empathy.  

     

    For companies wishing to follow this path, it's essential to start by assessing their data infrastructure and choosing AI tools tailored to their specific needs. Finally, by embracing a culture of continuous experimentation and investing in team training, companies can ensure they take full advantage of the benefits offered by AI.
