Business take

The case for ML-driven personalisation

Traditional search is no longer enough for your customers. Overwhelmed by hundreds of results to sift through, users struggle with decision fatigue, causing them to abandon their search and costing you conversions even when you have exactly what users are looking for.

Meanwhile, brands that leverage proprietary data for personalisation increase revenue by up to 10% two to three times faster than those that do not (Boston Consulting Group) and improve conversion rates by up to 50% (WiserNotify).

To turn the tide, you need to transform the raw behavioural data you already have into a ranking system that automatically surfaces the most relevant results for each individual user.

Serving your users exactly what they want in seconds boosts engagement, dramatically increasing conversions, and driving millions in incremental revenue.

The numbers are clear: our client, a global travel leader, achieved £2M in additional profit by implementing search personalisation on their website.
