The 2 CRO agencies in Northern Ireland
What each offers, one proof point, and who it suits.
1. Eyekiller: Full Digital Team
Eyekiller has worked from Bangor for over 23 years, building websites and running SEO, ads and CRO. Its CRO service uses A/B testing and design changes to improve user journeys.
Proof point: Echlinville Distillery says it has worked with Eyekiller for more than five years.
Good fit: CRO alongside a rebuild or campaign. Not a fit: a testing-only programme.
2. Propel Belfast: Dedicated CRO
Propel Belfast runs CRO in three phases: behaviour tracking, split and multivariate tests, then a post-test report.
Before you hire: its site shows no dated work from 2025 or 2026, so ask for a recent test.
Good fit: a one-off CRO project. Not a fit: buyers who need recent proof.
