Eurostar’s business challenge is a universal constant: how does it compete with travel operators to appear at the top of the results when people search by destination?

With this constant business challenge iProspect had to devise a strategy to solve it in a smarter way and return better results. 


iProspect saw an opportunity to build a system that could automate the media buying process for digital performance media. iProspect CORE is a machine learning-powered optimisation engine that automatically analyses, activates, and optimises media based on bespoke algorithms.

iProspect used CORE to automate the media-buying process for Eurostar, optimising both performance and efficiencies. 

Essentially, iProspect put paid search optimisation for Eurostar into the hands of their AI-based technology, leveraging the technology to make smarter portfolio buying decisions at a keyword level, improve and optimise search account structures and automate search query report processing.
