Conversion rate optimisation for UK small businesses (2026)
A 2026 conversion rate optimisation guide for UK small businesses — what to test, when you have enough data, and the changes that consistently lift conversion.

CRO at small business scale isn't about A/B testing button colours — most sites don't have the traffic for statistical significance. It's about removing friction the data already proves.
Diagnose before you optimise
Use Hotjar session recordings, scroll maps and exit surveys. Most conversion problems are obvious within 30 recordings.
Fixes that lift almost every site
Faster page load, mobile-first form simplification (4 fields max), visible trust signals above the fold, and a sticky CTA on long pages. These compound across every traffic source.
When to A/B test
Wait until you have at least 1,000 conversions/month on the page you're testing. Below that, qualitative research beats quant testing. Use A/B test calculators to confirm sample size before celebrating.
Brand vs CRO trade-off
Aggressive CRO often weakens brand. The best small business sites optimise for one or the other per page — sales pages convert hard, brand pages tell a story.
