WorkingCompany's own claimVendor ↗

Problem

TUI France, a subsidiary of the TUI Group and a leading French tour operator, wanted to cut the cost of its ad spend in a competitive travel market. Its CRM data and its Google Marketing Platform data were stored separately and in different formats.

Approach

With the partner Artefact, TUI France joined both datasets in BigQuery using the CRMint tool. Data scientists built a machine learning model on AI Platform that separates website visitors who are browsing from those likely to buy, and retrained it every week. TUI France used the scores to prioritize bids and to build lookalike audiences for display campaigns.

Results

7.5 times lowercost per sale on the display channel compared with before, per the head of digital analyticsCompany's own claim[1]
29%reduction in the cost of bringing customers to the website, per the head of digital analyticsCompany's own claim[1]

Takeaway

The model was one part of a wider data platform, so the savings cannot be split between the scoring and the data consolidation. TUI France planned a recommendation engine as the next step.
