Conversion Rate Optimization Services
Most CRO pitches skip the uncomfortable part: whether your traffic is high enough to prove anything at all. We start there. If you can run valid tests, we build the programme. If you can't yet, we say so and fix conversion the other way — with research, not statistics you don't have.
What this page covers, and what it doesn't
We run four adjacent services and they genuinely differ. Pick the one that matches your problem rather than reading all four.
Measurement setup, conversion research, hypothesis design and structured testing across any business model — lead generation, B2B, SaaS, service enquiries. Site-wide, not page-specific.
Store-specific work: checkout friction, product page structure, search and filters, mobile purchase flow. If your conversion problem is a cart, start there instead of here.
A specific page behind an ad campaign that isn't converting. Faster and narrower than a full CRO programme, and usually the right first move for paid traffic.
In-product journeys rather than marketing pages — signup, onboarding, feature adoption. Different research methods, different success metrics.
CRO improves the traffic you already have. If the constraint is that too few people arrive in the first place, that's SEO, paid advertising or lead magnets — and we'd rather tell you that than sell a testing programme your traffic can't support. Copy and offer changes often come out of this work too, which is where copywriting joins in.
Where conversion programmes actually go wrong
Sourced from Google's own product and Search documentation, Zoho's published pricing, and the standard public sample-size calculator — all linked below and verified 2 August 2026. Not from our sales deck.
The arithmetic that decides whether you can test at all
A/B testing needs volume, and the amount is larger than most people expect. Run the standard public sample-size calculator at its default settings for a site converting at 10.2% that wants to detect an improvement to 13.2%, and it returns 2,545 visitors per variation. That's roughly 5,100 visitors through the tested page for one two-way test, to detect a three-percentage-point swing.
The trap: real improvements are usually smaller than three points. Halve the effect you're hunting and the sample requirement roughly quadruples. A business sending 800 visitors a month to its enquiry page is not weeks away from a valid test — it is, on this arithmetic, years away, and no tool changes that.
This is the first thing we calculate, before quoting anything. It decides whether you get an experimentation programme or the low-traffic approach further down this page — and it's the reason we publish the number rather than discovering it three months into a retainer.
The free testing tool disappeared in 2023, and plenty of stacks never replaced it
Google Optimize and Optimize 360 were shut down on 30 September 2023, and Google's own notice states that any experiments still running on that date simply ended. Its explanation was blunt: Optimize "did not have many of the features and services that our customers request and need for experimentation testing." Google now points users to third-party integrations, naming AB Tasty, Optimizely and VWO as the partners it is collaborating with for Google Analytics.
The practical consequence for smaller businesses is that the free, default, good-enough option went away and was replaced by paid tools. Some sites still carry the dead Optimize snippet in their header years later. Others quietly stopped testing altogether and never revisited it. Part of any engagement here is deciding what the testing layer should be now — and that decision belongs with the budget, not with whatever was installed in 2021.
Most reported "wins" are noise that got stopped at a flattering moment
The most common failure in CRO is not a bad hypothesis. It's calling a test early. A result checked daily will, sooner or later, cross a significance threshold by chance — and if you stop the moment it does, you have recorded a coin flip as a discovery. Sample size has to be fixed before the test starts, and the test has to run to it regardless of how the chart looks on day three.
Two related habits matter as much. Tests need to run in whole weeks, because Tuesday traffic and Sunday traffic behave differently and a part-week skews the mix. And a "win" that isn't visible in revenue or qualified leads usually wasn't one — a lift in button clicks that produces no additional enquiries has moved a metric, not the business.
Testing tools measure what happened, not why — and only one of those generates hypotheses
An analytics platform tells you that 68% of people abandon a form. It cannot tell you they abandoned because the phone field rejected a valid number, or because the page asked for a GST number before explaining the price. That comes from session recordings, form-field analytics, on-site polls and actually talking to people who didn't convert.
This is where tooling choice matters more than it appears. Zoho PageSense bundles heatmaps, session recording, funnel analysis and form analytics into a free tier covering 5,000 monthly tracked users, which is enough for the research half of the work on a small site — but its own pricing page places A/B testing, split-URL testing and personalisation on the top Enterprise tier, so the free plan will not run your experiments. Knowing which capability sits behind which paywall prevents a common and expensive surprise three weeks into a project.

Conversion Research & Measurement
Find out what's actually broken, whether your tracking can even see it, and whether your traffic supports testing.
Before anything is tested or changed, we check that conversions are being recorded correctly, run the sample-size arithmetic on your real traffic, and gather the qualitative evidence that turns guesses into hypotheses. A surprising share of engagements end here with "your tracking was wrong, your actual conversion rate is fine" — which is a cheap and genuinely good outcome.
What you get
Analytics and goal-tracking audit, funnel drop-off analysis, session recordings and heatmaps on key pages, form-field analytics, an on-site poll or exit survey where useful, a sample-size feasibility calculation per key page, and a prioritised hypothesis backlog scored by expected impact against effort.
What it's not
Not implementation. You get findings and a ranked backlog, not shipped changes. It's also not a technical performance audit — crawl, indexing and Core Web Vitals sit with SEO services, though we'll flag speed problems severe enough to be a conversion issue in themselves.
Best for: every engagement, honestly. Also the right standalone purchase if you suspect your conversion numbers are wrong, or you want a second opinion before committing to a retainer with anyone.
Experimentation Programme
A continuous cycle of hypotheses, properly-powered A/B tests, and shipped winners — with the losers documented too.
Each test gets a written hypothesis, a fixed sample size calculated before launch, a full-week run schedule, and a decision recorded at the end whether it won, lost or was inconclusive. The six-month minimum isn't a sales device — at realistic traffic levels a single properly-powered test can take three to six weeks, so a shorter commitment produces two tests and no compounding.
What you get
A standing hypothesis backlog, tests designed and built on your chosen platform, fixed sample sizes agreed before launch, monthly win/loss reporting with revenue or lead attribution, and an archive of what didn't work so it isn't retried in eighteen months.
What it's not
Not a guarantee of a specific lift. Also not for you if your traffic can't reach significance — we'd be charging a retainer to generate noise, and we'll point you at the low-traffic tier instead. And not a redesign: if research shows the site itself is the constraint, that's website redesign or UI/UX design.
Best for: businesses with meaningful, steady traffic where a fraction of a percentage point is real money, and teams that want a documented testing history rather than a series of opinions.
Low-Traffic Conversion Programme
Improving conversion without pretending you can A/B test — research-led changes, shipped sequentially and measured honestly.
Most Indian SMB websites fall here, and almost nobody sells to them honestly. Below the sample-size threshold, A/B testing produces noise — but conversion still improves through evidence that doesn't need statistical power: session recordings, form analytics, customer interviews, and fixing friction that is obviously friction. Changes ship one at a time with before/after windows long enough to mean something, and we say plainly when a movement can't be attributed.
What you get
Ongoing qualitative research, one substantive change shipped at a time with a defined measurement window, form and funnel instrumentation, quarterly reassessment of whether traffic has grown enough to start testing properly, and reporting that separates "we improved this" from "this month was busier."
What it's not
Not statistically validated — and we won't dress it up as if it were. Sequential before/after comparison is weaker evidence than a controlled test, seasonality and campaign changes can confound it, and any agency claiming certainty at this traffic level is overselling. It's the honest best available method, not the ideal one.
How an engagement runs
The feasibility calculation happens before the proposal, not after the contract.
- Scoping call (free). We look at your traffic, conversion volume and goals, and tell you which tier the arithmetic supports — including when the answer is "not testing, not yet."
- Measurement check. Confirm conversions are tracked correctly before trusting any number. Broken or double-counted goals invalidate everything downstream, and they are common.
- Baseline and feasibility. Record current conversion rate and traffic per key page, then calculate the detectable effect at that volume. This determines what we can honestly promise.
- Research. Recordings, heatmaps, form analytics, polls and interviews — the evidence that produces hypotheses worth testing rather than opinions worth arguing about.
- Prioritise. Every hypothesis scored on expected impact against implementation effort, so quick wins ship before long builds.
- Test or ship. Properly-powered tests where volume allows; sequential changes with defined measurement windows where it doesn't. Either way the method is stated upfront.
- Report against baseline. Wins, losses and inconclusives, all recorded. The losses are the part that stops the same idea being retried next year.
How we measure — and what we won't claim
CRO attracts more inflated promises than almost any other service. Here's where we stand.
- Every number on this page traces to a public source. The 2,545-per-variation figure is what the standard public sample-size calculator returns at its default settings for a 10.2% baseline and a 13.2% target, reproducible from the link below; the Optimize shutdown date, Google's reasoning and its three named integration partners come from Google's own support documentation; the Zoho PageSense tier detail comes from Zoho's own pricing page. All linked below, verified 2 August 2026.
- We don't promise a specific conversion lift. Anyone quoting "2x your conversions" before seeing your analytics is guessing. Your baseline, traffic mix and how much has already been optimised determine the available headroom, and a well-run site has less of it than a neglected one.
- We won't sell a testing retainer to a site that can't test. This is the commonest quiet dishonesty in CRO. If the sample-size arithmetic says your traffic can't reach significance, we'll show you the calculation and recommend the low-traffic programme, which costs less.
- We report losses and inconclusive tests. A programme that reports only wins is either extraordinarily lucky or not reporting everything. Most well-run testing programmes have far more non-winners than winners, and that's normal rather than a failure.
- We separate correlation from causation. A festival sale, a new ad campaign or a seasonal swing can move conversion more than anything we changed. Where we can't attribute a movement confidently, we say so rather than claim it.
- We'll tell you when conversion isn't the constraint. If the funnel is sound and the traffic is simply too small or too poorly matched, that's a SEO, PPC or targeting problem, and we'd rather route you there than bill for optimising something that already works.
Frequently asked questions
How much traffic do I need before A/B testing is worth it?
More than most people assume. At the default settings of the standard public sample-size calculator, a page converting at 10.2% needs roughly 2,545 visitors per variation to reliably detect an improvement to 13.2%. That's about 5,100 visitors through that page for a single two-way test. Smaller improvements, which are the realistic ones, need substantially more. We run this calculation on your actual numbers during the scoping call, and if it says testing isn't viable we'll tell you rather than sell you a programme around it.
What replaced Google Optimize?
Nothing free and first-party, for websites. Google shut down Optimize and Optimize 360 on 30 September 2023, ending any experiments still running that day, and stated that Optimize lacked features its customers needed. Google now points to third-party integrations with Google Analytics and names AB Tasty, Optimizely and VWO as the partners it is collaborating with, having also opened its APIs so other tools can integrate. Practically, testing became a paid line item for most businesses — which is exactly why the feasibility calculation matters before you commit to a tool.
Can you improve conversions if we can't run A/B tests?
Yes, and that's a real service rather than a consolation prize. Below the sample-size threshold we rely on evidence that doesn't require statistical power: session recordings showing where people hesitate, form-field analytics showing which input causes abandonment, exit polls, and interviews with people who didn't buy. Changes ship one at a time with defined measurement windows. What we won't do is present that as statistically validated — sequential before/after comparison is genuinely weaker evidence, and pretending otherwise is how clients end up with confident reports and flat revenue.
How long does a single A/B test take?
As long as it takes to reach the sample size calculated before launch, rounded up to whole weeks. At realistic traffic levels that's commonly three to six weeks per test. Tests run in whole weeks because weekday and weekend visitors behave differently and a part-week distorts the mix. The one thing we won't do is stop early because the chart looks good — a result checked daily will eventually cross a significance line by chance, and stopping at that moment records a coin flip as a discovery.
What tools do you use?
It depends on budget and what already exists in your stack. For research, Zoho PageSense covers heatmaps, session recording, funnel and form analytics on a free tier of 5,000 monthly tracked users, which suits smaller sites — but note from Zoho's own pricing page that A/B testing, split-URL testing and personalisation sit on its top Enterprise tier, so the free plan won't run experiments. For testing specifically, Google names AB Tasty, Optimizely and VWO as its Analytics integration partners. We'll recommend based on your traffic and budget rather than a default, and we're happy working inside a tool you already pay for.
What does CRO cost?
We quote after the free scoping call, because traffic volume changes which engagement is honest to sell. Conversion Research & Measurement is the smallest fixed-scope piece and the usual entry point. The Experimentation Programme is a monthly retainer with a six-month minimum, because at realistic test durations a shorter term produces two tests and no compounding. The Low-Traffic Conversion Programme is a smaller monthly retainer with a three-month minimum. Testing tool licences are separate and billed to you directly rather than marked up.
Do you guarantee a conversion increase?
No, and we'd treat that guarantee as a warning sign from any agency. What we commit to is a correct measurement baseline, hypotheses grounded in your own user research, tests run to a sample size fixed before launch, and honest reporting that includes the tests that lost. A well-run programme produces more non-winners than winners — that's the normal shape of experimentation, and any report showing an unbroken run of wins is either very lucky or incomplete.
Will A/B testing hurt our SEO?
Not if it's built correctly, and Google publishes exactly how. Its testing guidance sets four rules: don't cloak (never show Googlebot a different version than humans — that's a spam policy violation regardless of testing, and note Googlebot generally doesn't support cookies); use rel="canonical" on variation URLs rather than noindex, which Google warns "can sometimes have unexpected bad effects"; use 302 temporary redirects rather than 301 permanent ones so the original URL stays indexed; and run the experiment only as long as necessary. That last rule has teeth — Google states that if it finds a site running an experiment for an unnecessarily long time it may interpret this as an attempt to deceive search engines and act accordingly. Removing test scripts and alternate URLs promptly after a test concludes is part of our process for this reason.
Is this the same as your e-commerce UX service?
No, and it's worth choosing deliberately. This page is the experimentation discipline applied across any business model — measurement, research, hypothesis design and testing for lead generation, B2B, SaaS and service businesses. E-commerce UX optimization is store-specific work on carts, checkouts, product pages and mobile purchase flows. If your conversion problem is an abandoned cart, that page is the better fit; if it's an enquiry form, a demo request or a signup, you're in the right place.
