How long does a typical A/B test need to run?
expand_more
It depends on traffic and conversion rate. We work out the sample size you need up front so the test can reach a reliable result. Most tests need at least a couple of weeks, and busy pages can finish sooner. We also avoid reading results during Ramadan, school holidays or the summer slowdown as if they were normal weeks. We never stop early just because one variant looks like it is winning.
What should we test first?
expand_more
We prioritise by potential impact (traffic, current conversion rate and likely lift) and by how easy the change is to build. Headlines, hero offers, form length, WhatsApp and call buttons, and trust signals on busy pages usually give the fastest and most reliable wins.
Do we need a dedicated testing tool?
expand_more
A tool helps with complex experiments and reliable statistics. We work with VWO, Optimizely, Convert and custom set-ups. For simpler tests we can sometimes use the testing features built into your ad platform or site builder, or a manual traffic split with careful analysis.
Can you test on pages with low traffic?
expand_more
Yes, but it takes longer to reach a reliable result. We often start on higher-traffic pages to learn quickly, then apply those lessons, with checks, to quieter pages. Where it makes sense, we can also use sequential tests or multi-armed bandit methods.
How do you avoid losing money while testing?
expand_more
We set clear success criteria and a stop-loss before launch. We watch for large negative effects and can roll back quickly. Most importantly, we test pages that already get meaningful traffic, so the cost of learning stays low compared with the upside. If you run Google Ads in AED, we keep ad spend steady during the test so results stay clean.
What is the difference between A/B and multivariate testing?
expand_more
A/B testing compares one element, or a small set of linked changes, against a control. Multivariate testing changes several elements at once to see how they interact. We usually begin with focused A/B tests for clearer, faster learning, and move to multivariate when we have a specific interaction to check.
Do you test on mobile and desktop separately?
expand_more
We analyse results by device and can run device-specific variants when behaviour differs a lot. In the UAE, most visitors arrive on a phone and many tap straight to WhatsApp or call, while office buyers in Business Bay or Downtown may browse on a desktop. Winners often differ between the two, so splitting by device matters.
How do you make sure results are statistically valid?
expand_more
We calculate the sample size before launch, set sensible confidence thresholds, account for peeking, and weigh practical significance alongside statistical significance. We write down the method so you can trust the outcome.
What if a test has no clear winner?
expand_more
That is still useful data. It shows the change was not big enough to matter, or that we need more traffic, or that the hypothesis was wrong. We record the result and move on to stronger ideas. Not every test produces a winner, and a good testing programme accepts that.
Can testing hurt user experience or brand?
expand_more
Badly designed tests can. We avoid tests that deliberately make the experience worse for half your visitors. We also keep your brand consistent, in English and Arabic, and only test variations that could live on the site long-term if they win.
How do you prioritise which pages to test?
expand_more
We weigh traffic, conversion potential and the effort to build. Busy pages with a lot of friction, such as enquiry forms, booking pages and key landing pages, usually rank first. We build a prioritised list of test ideas, with the likely value of each one explained.
Do you share raw data or just conclusions?
expand_more
We give you a clear summary with recommended actions, plus access to detailed results, dashboards and the method. You should be able to understand and challenge the findings.
How often should we be running tests?
expand_more
As often as we have good hypotheses and enough traffic to learn from. For many clients that means a few active tests each month once the programme is up and running. The aim is a steady run of proven improvements, not testing for the sake of it. Quieter months like the summer slowdown can be used to plan and build.
Can you help our team build an internal testing culture?
expand_more
Yes. We often train marketing and product teams in hypothesis writing, experiment design and reading results, so they can run their own tests over time. We can also stay involved as an ongoing partner or adviser.
