A/B Testing in St Albans
Running experiments on St Albans websites so decisions rest on evidence. The failures are rarely in the tooling and almost always in validity — traffic split unevenly, two experiments overlapping on the same page, or a result that reflects the novelty of a change rather than anything durable.
Why this comes up
The problem
Tests get run, winners get declared, and rolled-out changes never produce the improvement the test predicted.
What you get
What we deliver
- Randomisation verified, since uneven splits invalidate a test silently
- One change tested at a time, or a design that can separate the effects
- Duration set in advance and honoured, covering whole weeks of trading
- Overlapping experiments prevented, as they contaminate each other's results
- Results judged on practical difference, not only on statistical significance
- Outcomes recorded, including the losses, which most teams quietly discard

A/B Testing in St Albans — common questions
- Why do winning tests fail after rollout?
- Several reasons compound. Tests stopped early on a favourable result capture noise; novelty makes regular visitors react to change itself; and running many tests guarantees some appear to win by chance. Validated results survive rollout, and a great many reported wins are not validated.
- What is a sample ratio mismatch?
- When the traffic split does not match what you configured — sixty-forty on a fifty-fifty test, say. It indicates something is wrong with assignment or measurement, and any result from that test is untrustworthy regardless of how significant it looks. It is worth checking every time.
- Can we run several tests at once?
- On separate pages and separate journeys, yes. On the same page they interfere, and attributing an effect to either becomes guesswork. Organisations with high traffic can design for this properly; most should run one experiment at a time on any given flow.
- Should losses be recorded?
- Yes, and they are the more useful half. A tested idea that failed prevents it being proposed again next year, and patterns in what does not work teach more about your customers than a list of small wins. Most teams keep only the successes.
- Do you work with businesses across Hertfordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including St Albans and the surrounding Hertfordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Albans businesses do you usually work with?
- Professional services and consultancy systems for small firms serving London clients from a Hertfordshire base. Beyond that we work across Professional Services, Financial Services, Media, Retail and Construction.
- Do you cover the areas around St Albans?
- Yes — we work throughout East of England, including London, Milton Keynes, Cambridge. St Albans is an urban area of roughly 150,000+, and we take on work across the wider Hertfordshire region rather than the city boundary alone.
