In this case study Bas van de Haterd tells you about an old award winning case from the Airport of Schiphol. It's about a recruitment marketing campaign actually from some years ago, but that still holds it's place.
The excellence of this campaign was that is started with persona's, and really did what you are supposed to do with persona's, personalise the campaign based on them. So different ads, with different photo's, different motivators to want the job and different landing pages that corresponded with the ads.
