Let’s breathe life into great tech ideas! With more than 3 000 people globally, Intellias is a company where benchmark technological solutions are born. Join in and take your part in digitalizing the world.

What project we have for you

Our customer is one of the world’s leading pay-per-click (PPC) performance display advertising companies and a trusted partner of more than 3,000 e-commerce brands. The company operates commercially in 40 countries and is headquartered in France.

The product enables e-commerce businesses to extend their search marketing campaigns and re-engage visitors who have left their websites.

It helps improve online shopping by bringing the performance and precision of search advertising to display advertising. The solution delivers search-like performance: it is measurable, scalable, priced on a CPC basis, and driven by user intent. It enables advertisers to reach more potential customers, increase online sales, and achieve conversion rates and return on ad spend comparable to those of search campaigns.

Personalized banners significantly outperform standard display advertising and other retargeting formats, delivering higher click-through rates, increased on-site conversions, and higher average order values.
