Smartly.io and TUI Belgium ran an ad study to compare results from using the collection ad format compared to link ads which were had previously used in conversion campaigns.
Customizing the A/B Test With The Smartly.io Dynamic Image Templates
With Smartly.io's bespoke creative automation, each ad image was customized across the board with brand elements like the TUI logo and signature typography for hotel information.
Over a 10-day campaign in November 2017, TUI showed branded link ads and ads in the collection format to Custom Audiences created from TUI’s CRM (customer relationship management) data on past travel bookers and lookalike audiences based on recent bookers.
The 10-day campaign and ad study showed TUI Belgium a clear difference in results per ad type, with the collection ad format demonstrating higher engagement rates and at least half the booking cost of link ads. With this knowledge, TUI Belgium can now plan and create its direct response campaigns even more efficiently.
