Segmented Journeys

Lapsers, one-timers, and premium buyers? How to precisely segment Waitrose shopper journeys?

It’s easier than you might think. No manual segmentation is needed when you connect your first-party data with Deep Learning algorithms.

In real time, the bidding engine evaluates behavioral data and deploys sequential, personalised messaging for each group to prioritize future value.

We have proven this by working with other online grocery retailers in the U.K. Crucially, we protect your data. We only use it for the benefit of your campaigns.

Incremental Value

Some of our shoppers would have bought anyway.

How can we prove that our campaign budget is bringing incremental value?

It’s a natural question to ask. But different providers will give you different answers on how to measure uplift.

We’ve found that validating incremental value with fully independent tests using the Ghost Ads methodology

is the most transparent and robust way to determine real value.

See how it works.

Full-Funnel Performance

If the lower funnel captures demand that already exists, how can we accelerate growth in our pool of future customers?

The key is to replenish your pool with more new households by reaching shoppers before they actively enter the market.

This way, you expand the Waitrose user pool rather than recycling it.

It’s diversified, scalable reach powered by sequential storytelling and full-funnel display across premium publishers (like The Guardian).

You can identify in-market audiences with high intent in the middle funnel with Quality Traffic,

a solution that uses LLM-powered audiences and semantic signals to drive tag-validated visits rather than empty clicks.

The challenge.

The solution.

RTB House paired Streaming Video Ads with its Deep Learning and ContextAI, serving high-potential shoppers personalised video that showed fragrance and lingerie in an aspirational light and drew them back to the Debenhams store.
