A/B Testing & Experimentation
Guesswork has no place in improvement. We build structured test plans, run variations simultaneously, and only implement changes that prove themselves with statistically significant data.

Durham businesses deserve websites that perform. We use behavioural analytics, structured A/B testing, and landing page refinement to turn your existing traffic into measurable commercial results.
No fluff. No jargon. Just proper work that moves your business forward.
Guesswork has no place in improvement. We build structured test plans, run variations simultaneously, and only implement changes that prove themselves with statistically significant data.
Your visitors tell you exactly where your site fails them — through their behaviour. We decode that data, eliminate friction, and create a clearer path from interest to action.
A well-improved landing page turns paid clicks into genuine enquiries. We rework messaging, visual hierarchy, and form placement to maximise the return on every pound you spend driving traffic.
We ground every recommendation in evidence. Heatmaps show where attention gathers, session replays reveal confusion, and analytics highlight the pages that leak the most value.
Durham’s professional services, education, and heritage sectors all depend on digital to attract clients. CRO ensures the marketing budget you’ve already committed delivers a stronger return — more enquiries, more bookings, more revenue from the same volume of visitors.
We’re a short drive from Durham and already work with businesses across the county. Our approach is methodical: gather data, form hypotheses, test rigorously, and implement what works.
From professional services firms to visitor attractions, we work with Durham organisations to improve their websites and funnels — turning passive browsers into active customers.

Everything you need to know about our CRO Durham service.
CRO — Conversion Rate Improvement — is the practice of improving your website so a greater proportion of visitors take the action you want, whether that’s an enquiry, a booking, or a purchase. At Capture Expense, our CRO work delivered a +285% conversion rate improvement.
We rely on hard data rather than opinions. Heatmaps, session recordings, and analytics reveal where visitors hesitate or abandon. For Gentoo Homes, this evidence-based method drove +58.61% more views per user and +85.07% longer engagement times.
A/B tests generally need 2–4 weeks to produce statistically reliable results. You’ll see early improvements within the first cycle, and those gains compound as we run successive rounds of testing and refinement.
Significantly. When your landing pages convert better, your cost per acquisition drops across every paid channel. At Capture Expense, combining CRO with PPC restructuring created a dramatic uplift in overall conversion performance.

Had a website made from scratch was done within 4 days and turn around was great.
