ঢাকার ওয়েবসাইটের জন্য A/B টেস্টিং প্রোগ্রাম
A structured monthly A/B testing programme — ICE-scored hypotheses, statistically-significant tests via VWO or GrowthBook, and shipped winners on your highest-traffic pages every 30 days.
একটি structured মাসিক A/B টেস্টিং প্রোগ্রাম — ICE-scored হাইপোথিসিস, VWO বা GrowthBook-এ পরিসংখ্যানগতভাবে গুরুত্বপূর্ণ টেস্ট, প্রতি ৩০ দিনে shipped winners।
An A/B testing programme in Dhaka is a monthly cycle of ICE-scored hypotheses tested via VWO or GrowthBook on the client's highest-traffic pages. Digital Marketing Dhaka runs the whole loop — hypothesis backlog, test design, statistical significance monitoring, and shipping winners — with a target of 6–10 significant winners per quarter on landing, product and checkout pages.
ঢাকায় A/B টেস্টিং প্রোগ্রাম মানে — ICE-scored hypothesis-এর মাসিক cycle, highest-traffic পেজে VWO বা GrowthBook-এ টেস্ট। Digital Marketing Dhaka পুরো loop চালায় — hypothesis backlog, test design, significance monitoring, winner shipping — quarter-এ ৬-১০টি significant winner target।
Most Dhaka websites A/B test nothing, so redesigns are guesswork and CRO advice is 'best practice' opinions. Traffic is expensive: BDT 22–65 CPM on Meta, BDT 45–180 CPC on Google. Squeezing 10–20% more conversion out of the same traffic is cheaper than acquiring more traffic. A disciplined testing programme compounds — every winner is permanent, every loser is a documented reason to stop guessing.
ঢাকার বেশিরভাগ ওয়েবসাইট A/B test করে না — তাই redesign আন্দাজে হয়, CRO advice 'best practice' opinion। Traffic ব্যয়বহুল: Meta CPM BDT ২২-৬৫, Google CPC BDT ৪৫-১৮০। একই ট্রাফিকে ১০-২০% বেশি কনভার্সন — নতুন ট্রাফিক আনার চেয়ে সস্তা। শৃঙ্খলিত programme compound করে।
Ongoing backlog of 20–40 test ideas at any time, each scored on Impact / Confidence / Ease. Top 2–3 tests picked monthly from data + heatmaps + session replays.
Marketing-led tests via VWO (visual editor, fast setup). Engineering-led tests via GrowthBook (feature flags, dev-owned). We install + manage either.
Bayesian or frequentist analysis with 95%+ confidence targets. Tests run until statistically-called, not until 'looks like a winner'.
Every test scoped upfront: minimum detectable effect, expected runtime given traffic, guard rails. No wasted tests on underpowered pages.
Every variant tested on Chrome, Safari, mobile Chrome, small Android screens, and Bangla-content pages before traffic split. Bangla wraps differently — regularly breaks button widths.
Winner ships to production within 5 business days of test end. Loser gets a documented postmortem so the hypothesis doesn't come back next quarter.
Every test archived with hypothesis, variants, results, learning. Six months in, you have a documented playbook of what actually works on your audience.
60-min quarterly session — what did we learn, what patterns emerged, what should we test next quarter, what's the expected impact.
VWO or GrowthBook installed + verified. Analytics goals mapped. Baseline conversion rates measured.
90-min workshop building the initial backlog from heatmaps, session replays, GA4 funnels + team observations.
Highest-ICE test scoped, designed, QA'd, launched.
2–3 tests running concurrently on different pages, monthly review + roadmap update.
'Move the CTA above the fold', 'add urgency countdown', 'use red buttons'. Every one of those tests has both won and lost thousands of times across the industry. Best practices average out to zero net lift. The only advice that matters is: what wins on your specific audience, your specific product, your specific market. A/B tests give you that answer — nothing else does.
The single most common testing mistake in Dhaka is calling a test after 3 days because 'it looks like variant B is winning'. Without statistical significance, that 'win' is 60–70% likely to reverse in production. We enforce minimum sample sizes and 95% confidence — often 2–4 weeks per test — and we call losers as clearly as winners. Slower cadence, real wins.
A/B tests great for one-variable changes (headline, button copy, hero image). But when you're redesigning a whole checkout flow, you're changing 15 things at once — an A/B test tells you 'B is better' but not 'why'. For those, we run multivariate tests (via VWO) or ship a full redesign then A/B-test individual elements after. Choosing the right test type is 80% of getting real learnings.
One test rarely changes a business. Twenty documented tests over six months change how the whole marketing team thinks. When a new team member joins, they read the library and stop repeating the tests that lost. When a redesign is proposed, the library says 'we tested that in March, here's the data'. This institutional memory is the real ROI of a testing programme — not any single winner.

Q. How much traffic do you need to A/B test?
A. You need roughly ten thousand monthly page views on the tested page for reasonable test runtimes.
Q. VWO or GrowthBook — which is better?
A. VWO is best for marketing-led tests with a visual editor; GrowthBook is best for engineering-led tests using feature flags.
Q. How long should an A/B test run?
A. Most A/B tests should run two to four weeks to reach ninety-five percent statistical confidence, not just when a winner looks obvious.
A Uttara-based EdTech saw checkout conversion stuck at 3.4% for 8 months. In the first quarter of testing we ran 7 tests: 3 winners (mobile CTA colour + copy = +11%, trust badges near payment = +8%, remove secondary CTA in hero = +6%), 3 losers, 1 inconclusive. Compounded improvement: 3.4% → 4.2% checkout conversion — a 23.5% lift on the same traffic, worth ~BDT 3.8 lakh/month at their volume. Cost of the programme: BDT 45,000/month.
উত্তরার একটি EdTech-এর checkout conversion ৮ মাস ৩.৪%-এ আটকে ছিল। প্রথম quarter-এ ৭টি টেস্ট: ৩ winner (mobile CTA colour + copy = +১১%, trust badge = +৮%, secondary CTA বাদ = +৬%), ৩ loser, ১ inconclusive। Compounded: ৩.৪% → ৪.২% — একই ট্রাফিকে ২৩.৫% lift, মাসে BDT ৩.৮ লাখ। Programme cost: মাসে BDT ৪৫,০০০।
Minimum ~10,000 monthly page views on the tested page for reasonable test runtimes. Below that, we recommend qualitative research + shipping instead.
VWO if marketing owns the tests (visual editor, no dev). GrowthBook if engineering owns them (feature flags, code-based). Both are excellent.
2–3 concurrent tests on different pages is safe. More risks statistical interference.
Yes — VWO visual editor for simple tests, in-house design + dev for complex ones. Everything ships production-ready.
টেস্ট পেজে মাসে অন্তত ১০,০০০ page view। কম হলে qualitative research সুপারিশ।
মার্কেটিং টেস্ট চালালে VWO। ইঞ্জিনিয়ারিং চালালে GrowthBook।
২-৩টি concurrent test, ভিন্ন পেজে — বেশি হলে statistical interference।
হ্যাঁ — সরল টেস্টে VWO editor, জটিল টেস্টে in-house design + dev।
