What conversion rate optimization actually is
Increasing the share of your existing visitors who buy, register, enquire or deposit, using research and controlled tests rather than opinion. The traffic does not change. What it does on arrival does.
The loop repeats: measure, find the drop-out, write a hypothesis, test on live traffic, ship or revert. That is the process set out in Semrush's guide to CRO. The step agencies skip is the first.
Not SEO
SEO changes how many arrive. CRO changes what share act. A ranking gain is worth more once the page converts, which is why we run both.
Not a redesign
A redesign changes the look, all at once, on taste. It is also the most common way a working conversion rate gets destroyed.
What it cannot fix
Wrong audience, weak offer, rejected pricing, no demand. When the problem sits upstream, the audit names it instead of selling a test programme.
Who this is for, and when it is too early
CRO earns its keep when you already pay for traffic and the rate has flattened: a small lift applies to volume you already bought. If traffic itself is the problem, that is a paid search question, and we say so rather than take the retainer.
The constraint is conversions, not visitors. A modest site with a high-value action can often test. A busy site whose conversion is rare cannot. And if everything you buy lands on one standalone page, the job is landing page optimization rather than a site-wide programme.
A good fit
Meaningful monthly conversions, an action worth real money, a plateaued rate, and someone who can approve a change without a committee.
Too early
Low conversion counts, a page that changes weekly, an offer still being decided, a replatform in flight. Results there look confident and do not hold.
What we do instead
Audit-led fixes, shipped in order of expected impact, with the confounders written down. Detail in when not to test.
How we find out why people leave
Analytics tells you where visitors drop out. It never tells you why, and why is the part a test needs. So the first weeks are research, from six sources.
Analytics and funnel
Drop-off by step, split by device, source and returning versus new. One broken mobile step hides easily inside a healthy average.
Session replay
We watch the sessions that failed, not the ones that converted. Rage clicks, dead clicks, the scroll that stops just above the answer.
Form and field analytics
Which field is abandoned, which throws an error, which takes longest. Lead-generation loss is usually one field, rarely the suspected one.
On-site questions
One question at the point of hesitation, one after the action completes. Switched off once answered, and often the fastest route to a hypothesis.
People who talk to customers
Sales calls, support tickets, refund reasons, the objection your team answers ten times a week. The cheapest research in the building.
Heuristic walkthrough
A senior completes the task on a phone, as a first-time visitor who has never heard your internal vocabulary.
Findings enter the backlog as hypotheses, not observations, in one shape: because we observed X, we expect changing Y to Z will improve A, measured by B. Anything that cannot be written that way is a preference, and preferences are not tested. Each is scored on impact, confidence and ease, and you reorder before anything is built.
You cannot optimise numbers you have not checked
CRO is arithmetic performed on your analytics. If it runs on a conversion event that fires twice, a thank-you page reachable by refresh, or a payment gateway that drops the session, every decision downstream inherits the error and looks confident doing it.
So every engagement opens with a tracking audit, before research and long before a test. We reconcile what analytics reports against what your back office recorded, and tell you the gap. A small gap is normal. A gap nobody can explain is the first finding.
Where the foundation needs rebuilding rather than patching, that is GA4 implementation work, quoted separately, with Google Tag Manager on the event layer and tracking and reporting for dashboards.
What the tracking audit checks
What a test costs, and how we decide something actually worked
The standard is set before the first test and does not move because a result disappointed.
A test is priced in conversions, not visitors, and four inputs set the bill: your current rate, the smallest change you would act on, the confidence you want before acting, and how often you are willing to miss a real effect. We fix the last two at the conventional 95% and 80%. The first is whatever your site does today. That leaves the second, and it is where testing plans quietly fail, because halving the effect you want to detect multiplies the traffic needed roughly fourfold.
So the question is never whether you have enough traffic. It is how small a change this page could prove in a sensible window, and whether a change that size is plausible here. If only a transformation would register, the test is theatre, and we say so before you pay for it.
The calendar costs too. While a test runs the surface is frozen: no campaign restructure pointing at it, no price change, no second test stacked on top. And half your visitors spend the period on a version that may be reverted.
Our testing standard
"No agency can guarantee a specific lift. Anyone quoting a number before seeing your data is guessing, and you pay for the guess."
The Web Push testing standardWhen not to test, and what we do instead
Many sites that ask for CRO cannot run a valid A/B test on the page they care about. That is arithmetic, not a failing, and pretending otherwise is how agencies end up quoting uplift figures they cannot support.
Four situations where a test is the wrong instrument. The change is a defect fix, such as a validation message that never appears on mobile, so nothing is gained by leaving half your visitors on the broken version. The change is required by law, licence or consent rules, so it ships regardless. The site is moving underneath the test, mid replatform or mid campaign restructure. Or the result would not change the decision, because you will ship it either way.
Fix, then measure the fix
Defects ship immediately, dated, one at a time, read against the same window last period with every confounder named next to the number.
Evidence that needs no volume
Recordings, field drop-off, support tickets and on-site questions need no sample size. They cannot prove a lift, but they answer why.
Measure higher up the funnel
Form starts and step completions outnumber purchases, so they read faster. We treat them as leading indicators and confirm revenue over a longer window.
None of it substitutes for a controlled test and we will not present it as one. A before-and-after reading cannot separate your change from the season or the campaign. What it can do is stop a site shipping nothing for a year while it waits for volume it may never reach.
How the work runs: research, hypothesis, test, ship
You deal with the senior doing the work. Building and running each test in your tool is standard; where a licence or policy rules that out, your developer receives annotated specifications and acceptance criteria.
Instrument
Tracking audit, reconciliation against your own order or CRM data, and the fixes that make later numbers trustworthy.
Research
Funnel analysis, session replay, form analytics, heuristic walkthrough, customer input. Output: where visitors leave, and why.
Prioritise
Each hypothesis gets a score, a target metric and a calculated sample size. You reorder the backlog before anything is built.
Test, ship or revert
One test per surface against a control, run to the agreed sample size. Winners ship, losers revert, flat is written up as flat.
In every engagement
How results reach you, and how you check them
Every test closes with a written record, whatever it did: hypothesis, what changed, both variants side by side, the metric agreed at the start, the numbers per variant, and the decision. A flat result gets the same write-up as a win.
A result you cannot reproduce is not a result. Our figures come out of your analytics property and your testing tool, which you own and can open without asking us. If a number in the report does not match your own account, that is a tracking defect and we treat it as one.
Monthly you get the roll-up: what ran, what shipped, what was reverted, what is queued. Not a slide claiming an uplift with no denominator and no mention of the tests that went nowhere.
In every test write-up
Three ways in, so pick the right one
The method above is the same everywhere. Where the money leaks is not. This page is the hub: research, statistical standard, reporting. The two below go deep on one funnel each.
You run an online store
Loss spreads across collection, product, cart and checkout, the metric has to be revenue per visitor, and your platform decides what is testable.
Ecommerce CRO agency →You buy clicks to one page
Paid traffic on a standalone page is a different job: message match against the ad, offer clarity, form friction, and the page build itself.
Landing page optimization →Casino and iGaming
Registration and deposit flows, tested inside licence terms, geo rules and responsible-gambling limits. We optimise within your compliance rules; we do not write them.
Our casino and iGaming work →What conversion rate optimization services cost
Two shapes, and we tell you which your site needs rather than selling the larger one. A scoped project is fixed work with an end: tracking audit, research, ranked backlog, a defined round of fixes or tests. A monthly programme keeps the loop running.
Three things move a quote: site complexity, surfaces in scope, and whether we implement or specify. Analytics rebuilds and heavy development are quoted separately, because bundling them hides what you are paying for. No retainer to begin, no long-term contract, no notice period, and your number arrives with the free audit.
How we charge
Find out whether your site can be tested
Volume shops solve capacity by hiring in bulk. We solved it by taking fewer clients, so every hour is worked by a senior and you message that person directly. No 24/7 desk, no enterprise programme, no account manager. More on how the agency is run.
Send the URL, the action that matters, and roughly how many of them you get in a month. Within 24 hours: where the funnel leaks, what is worth the first round, whether your volume supports a valid test, and an exact quote. If it does not, the audit says so and lists what to ship without one. Rather email? Talk to us.
Fair questions, straight answers
What is conversion rate optimization?
Increasing the share of existing visitors who complete a desired action, such as a purchase, signup or enquiry, through research and controlled testing. The output is tested changes with measured results, not a redesign shipped on taste.
How much traffic do I need for CRO to be worth it?
Monthly conversions matter, not visitors. The threshold depends on your current rate and the smallest change you would act on, because a smaller effect needs far more traffic to prove. The free audit runs that calculation on your figures.
Can you guarantee a conversion rate increase?
No, and neither can anyone else. Tests come back flat, and a provider quoting an uplift figure before seeing your account is guessing. What is fixed is the method, written out row by row under our testing standard above, and we hold to it whether the result flatters us or not.
What if my site cannot support A/B testing?
Then the audit says so and we do not sell you a testing programme. We fix defects that need no control group, decide on evidence that needs no volume, and measure higher up the funnel where counts are larger, with the confounders written next to the number.
How much do conversion rate optimization services cost?
A scoped project with a defined end, or a monthly programme that keeps the loop running. Complexity, surfaces in scope and whether we implement or specify move the number. No retainer, no long contract, and an exact quote with the free audit.
How long does it take before CRO shows results?
Tracking fixes and low-risk wins land in the first weeks. A tested result takes as long as your volume dictates: enough conversions to reach the agreed sample size, across full weekly cycles. You get the projected run time before the test starts.
Which testing and analytics tools do you use?
Whatever you already pay for: GA4, one client-side testing tool, one session-replay tool, kept to a single lightweight snippet rather than a stack. If you have no tooling we recommend one setup, and you hold the licences.
Do you implement the changes, and what access do you need?
Building and running the tests ourselves is standard and faster; otherwise your developer receives annotated specifications, copy and acceptance criteria. Either way we need read access to analytics and the ad accounts, permission to install a testing script, and implementation access or a developer contact. Not admin rights on hosting, payments or customer data.
What is a good conversion rate?
There is no universal number and we will not quote one. It moves with industry, traffic source, price point, device and the action. Split your own twelve months by channel and device, then compare each segment against its own history.
What is the difference between CRO and SEO?
SEO increases how many people arrive; CRO increases what share of them act. They compound, because a ranking gain is worth more on a site that converts better. We run both, so the recommendation is not biased toward whichever we happen to sell.
