A/B & Multivariate Testing
Stop Guessing. Start Knowing.for the UK
Built for UK owner-led businesses competing in British search. We run planned tests on your pages, showing two versions to different visitors to see which brings in more leads. The results, not opinions in a meeting, decide what stays.

Why Most Testing Programs Fail
Common Testing Mistakes
- Changing too many things at once, so you learn nothing in the UK
- Stopping tests too early or running them too long in the UK
- Ignoring differences between visitor types, such as phone versus desktop in the UK
- No way to rank ideas, so random ones get tested
- Results never used to guide the rest of your marketing in the UK
Our Philosophy
Good testing is a steady process, not a string of random experiments. Each test starts with a clear guess about why visitors behave as they do. We run it long enough to trust the result, and we start with the pages that matter most. Every win builds on the last in the UK.
How We Run High-Impact Experiments
Prioritization & Hypotheses
- Opportunity Scoring: We rank pages and page elements by how many visitors they get, how much they could improve, and how easy the change is in the UK.
- Clear Hypotheses: Every test starts with a specific guess that the test can prove wrong, based on how visitors behave or what the data shows in the UK.
- Segment Awareness: We split results by where visitors came from, their device, and their audience, so we know who the win is for in the UK.
Execution & Analysis
- Proper Statistical Rigor: We use enough visitors and a high bar for confidence, and we do not stop a test early just because one version looks ahead in the UK.
- Full Instrumentation: Click tracking, recordings of visits, and heatmaps (maps of where visitors click and scroll), so we learn not just what won, but why in the UK.
- Actionable Reporting: Clear winners, losers, and what to test next, with the likely effect on your business in the UK.
Our A/B & Multivariate Testing Process
01
Audit & Prioritization
Identify highest-impact pages and elements using data and opportunity scoring in the UK.
02
Hypothesis Development
Form specific, testable hypotheses based on user behaviour, qualitative research, and analytics in the UK.
03
Test Design & Setup
Design variants, set up tracking, and configure the experiment with proper segmentation and goals in the UK.
04
Run & Monitor
We work out up front how many visitors the test needs, then check it is running properly without peeking at early results in the UK.
05
Analysis & Learning
We check that the result is reliable, work out why the winner won, and write down what we learned in the UK.
06
Implement & Iterate
Roll out winners, apply learnings to other pages, and plan the next round of high-value tests in the UK.
FAQ
Common questions
Answers for businesses in the UK.
How long does a typical A/B test need to run?
It depends on traffic volume and conversion rate. We calculate required sample size upfront so the test reaches statistical significance. Most tests need at least 1-2 weeks; high-traffic pages can conclude faster. We never stop early just because one variant is "winning." in the UK
What should we test first?
We prioritise by potential impact (traffic × current conversion rate × estimated lift) and ease of implementation. Headlines, hero offers, form length, and trust signals on high-traffic pages usually deliver the fastest, most reliable wins in the UK.
Do we need a dedicated testing tool?
A testing tool helps for complex experiments and gives more reliable results. We work with tools such as VWO, Optimisely, and Convert, or build a custom setup. Google Optimise was shut down in 2023. For simpler tests we can sometimes use the testing tools built into your website platform, or split traffic by hand and analyse it carefully in the UK.
Can you test on pages with low traffic?
Yes, but it takes longer to reach significance. We often start with higher-traffic pages to generate learnings quickly, then apply those insights (with validation) to lower-traffic pages. We can also use methods that shift traffic toward the better version as a test runs, when that suits in the UK.
How do you avoid "losing" money while testing?
We set clear success rules before each test, plus a limit on how much a weaker version can cost you. We watch for large drops and can switch back quickly. Most importantly, we focus tests on pages that already have meaningful traffic so the cost of learning is low relative to the upside in the UK.
What's the difference between A/B and multivariate testing?
A/B tests one element (or a small set of coordinated changes) against a control. Multivariate tests multiple elements simultaneously to understand interactions. We usually start with focused A/B tests for clearer, faster learnings and move to multivariate when we have specific interaction hypotheses in the UK.
Do you test on mobile and desktop separately?
We analyse results by device and can run device-specific variants when behaviour differs significantly. Many tests show different winners on mobile vs desktop, so segmentation is important in the UK.
How do you make sure results are statistically valid?
Before launch we work out how many visitors we need, and we set a high bar for confidence (typically 95% or more). We do not stop early on a lucky streak, and we check that a win is big enough to matter for your business. We write down our method so you can trust the outcomes in the UK.
What if a test has no clear winner?
That's still valuable data. It tells us the change wasn't material, or that we need more traffic, or that the hypothesis was wrong. We document the null result and move on to higher-impact ideas. Not every test produces a winner, and good testing programmes accept that in the UK.
Can testing hurt user experience or brand?
Poorly designed tests can. We avoid tests that deliberately degrade experience for half your visitors. We also consider brand consistency and only test variations that could plausibly live on the site long-term if they win in the UK.
How do you prioritize which pages to test?
We rank pages by how many visitors they get, how much they could improve, and how hard the change is. High-traffic, high-friction pages (checkout, lead forms, key landing pages) usually rank highest. We build a prioritised backlog with estimated ROI for each test idea in the UK.
Do you share raw data or just conclusions?
We provide clear executive summaries with recommended actions plus access to detailed results, dashboards, and methodology. You should be able to understand and challenge the findings in the UK.
How often should we be running tests?
As often as we have good hypotheses and enough traffic to learn. For many clients that means 2-6 active tests per month once the program is mature. The goal is a steady cadence of validated improvements, not testing for the sake of testing in the UK.
Can you help us build an internal testing culture?
Yes. We often train marketing and product teams on hypothesis development, experiment design, and reading results so they can run their own tests over time. We can also stay involved as ongoing partners or advisors in the UK.
How do we get started with better testing?
Book a free CRO audit. We'll review your current pages, data, and testing history (if any), identify the highest-ROI opportunities, and deliver a prioritised testing roadmap with expected impact in the UK.
