Travel CRO: Conversion Rate up 14.45% on Lower Paid Media Spend

An ongoing CRO programme inside a booking flow — A/B testing plus a cart that lets hotels be added to a flight in one session.

The problem

At a major travel platform we led an ongoing CRO initiative to increase the efficiency of marketing spend by improving user conversion rates and bookings while reducing paid media spend, identifying and implementing high-impact conversion opportunities within the booking flow.

  • Needed to increase bookings and conversion rates while simultaneously reducing paid media spend
  • Required identifying high-impact conversion opportunities within a complex booking flow
  • Drop-off at the customer details page was a critical conversion blocker

What we did

A/B testing programme

  • Conducted A/B testing to identify conversion opportunities in the booking flow
  • Implemented quick experiments and rapidly deployed successful changes

Cart system innovation

  • Introduced a cart system allowing users to add hotels to flight bookings in the same session
  • Mimicked e-commerce UX patterns to reduce friction
