Ad-citing times for 'retargeter' Criteo

YUKO Saito is in the business of following you across the Internet, long after you've abandoned a shopping cart filled with jeans, books or a trip to Bali.

If you'd stopped just short of buying, say, a pair of cute hot pants on a retailer's site, ads for that retailer will pop up later on different sites or mobile apps, filled with items that are geared towards getting you to go back to the online store and buy something.

This practice of subtly tracking the consumer across the great virtual abyss is called "retargeting", and for firms like Nasdaq-listed Criteo, it is their bread and butter.
