What is a CRO consultant?
A CRO consultant is a conversion rate optimization specialist who works out why a website's visitors are not buying, signing up or getting in touch, and directs the changes and tests that fix it. Unlike a CRO agency, a CRO consultant usually does not design or code the changes. They decide what should change and why, and your team builds it.
You will see the same role called a conversion rate optimization consultant, a conversion optimization consultant or, in British spelling, a conversion rate optimisation consultant. Firms that sell the work call it CRO consulting services or a CRO consultancy.

Which CRO is this?
CRO also stands for contract research organization in medicine, and for Chief Revenue Officer in sales, which is why some results for "CRO consultant" are about clinical trials. This page is about conversion rate optimization.
CRO consultant, CRO expert or CRO specialist?
A CRO consultant, a CRO expert and a CRO specialist do the same work: finding why visitors do not convert and fixing it. "Consultant" usually means someone who advises several companies from outside, "specialist" is the usual job title for an employee or a freelancer, and "expert" is how either one describes themselves.
So when you search for conversion rate optimization experts, judge the person by their process and their evidence, not by the title. If you are hiring someone onto your team, the CRO specialist guide covers the day-to-day role, the skills to look for and how an in-house hire, a freelancer and a consultant compare.
What does a CRO consultant do?
A CRO consultant turns your analytics and your visitors' behavior into a short, ranked list of changes, then makes sure each change is tested or shipped properly.
Audits the site and the data. Checks that tracking is accurate, then finds the pages and steps that lose the most visitors.
Works out why. Uses analytics, heatmaps, session recordings, surveys and a hands-on review to explain the drop-off.
Builds a test roadmap. Turns each finding into a hypothesis and ranks them by traffic, likely impact and effort.
Directs the work. Briefs your designer or developer on exactly what to change.
Sets up tests properly. Decides sample size and duration before a test starts, so results can be trusted.
Reads the results. Explains what a test showed, what it did not show, and what to do next.
What a CRO consultant usually does not do: design and code your pages (that is agency work, priced that way), run your ads, SEO or email, or guarantee a lift. Anyone who promises a fixed percentage before seeing your data is guessing.
What CRO consulting services usually include
CRO consulting services usually produce six things: a tracking check, an audit of findings, a ranked backlog, briefs for each change, a review of every test before launch, and a written read of each result. Scope varies by consultant, so ask to see an example of each before you sign.
Typical CRO consulting deliverables, and what good looks like
Deliverable
What it is
What good looks like
Tracking check
Confirms that conversions in analytics match real orders, sign-ups or leads
Every gap is named, with how much it distorts the numbers
Audit findings
Where visitors drop off and why
Each finding cites its evidence: a report, a recording, a survey answer
Ranked backlog
Every fix and test idea in one ordered list
The ranking method is written down, so you can argue with it
Change and test briefs
What to build, for which pages, and why
A developer can build from it without a meeting
Test setup review
A check of each test before it goes live
Hypothesis, primary metric, sample size and stop date agreed in advance
Results read
What each test showed and what happens next
Losses and inconclusive tests are reported as plainly as wins
A free CRO audit covers the first two rows. Ongoing consulting covers the rest, because test review and reading results only happen once tests are running.

Hire a CRO consultant when you have steady traffic, someone who can build changes, and no clear answer to why more visitors do not convert. You probably need one if several of these are true.
Traffic is growing and revenue is not keeping up.
You are paying more for each visitor than you were a year ago.
You have changed the site several times and cannot say which changes helped.
Your team runs tests, and most end without a clear result.
Mobile brings most of your visitors and a small share of your sales.
People start your checkout or form and do not finish, and nobody knows why.
You are about to redesign the site and want evidence to guide it, not only the principles of conversion design.
If the last one is you, start with an audit before the redesign, not after. Convertica's website redesign services work in that order: every page is audited first, then Convertica's team builds the fixes.
When to hold off
Nobody can build the changes. Advice that sits in a document changes nothing. Line up developer time first, or choose a provider that builds, such as Convertica's one page rebuild, where Convertica's team builds every fix the audit found on the page.
The offer itself is unproven. If almost nobody buys at any price, the problem is the product or the market, and a better page will not fix it.
You are replatforming soon. Testing on a site that is about to be replaced wastes traffic. Bring the consultant into the rebuild instead.
Traffic is very low. You can still fix clear problems, but formal A/B testing may not be possible. The A/B test sample size calculator shows what your traffic allows.
CRO consultant, agency, in-house or fractional CRO?
A CRO consultant gives you direction, an agency gives you direction and a team that builds, an in-house specialist gives you one full-time person, and a fractional CRO consultant gives you senior direction part-time on an ongoing basis. Be honest about which one you are missing: direction, people, or both.

Advice that nobody implements
Paying for capacity you do not use
One person with no senior peer to check their thinking
Too few hours if your team needs daily help
The most common mistake is hiring an agency when the real gap is direction, or hiring a consultant when nobody is available to build what they recommend. Convertica's CRO services page sets out what Convertica sells, including the rebuilds for teams with nobody to build. If you run an agency and want to offer CRO to your own clients, see white label CRO.
What is a fractional CRO consultant?
A fractional CRO consultant is a senior conversion specialist who works with your team part-time on an ongoing basis, instead of as a full-time hire. In practice, fractional CRO in this sense is the same thing as a CRO consulting retainer.
Most searches for "fractional CRO" are about something else: a part-time Chief Revenue Officer, who runs sales and revenue strategy. That is a sales leadership hire. If a provider offers "fractional CRO", check which one they mean before you book a call.

How to choose a CRO consultant: eight questions to ask
To choose a CRO consultant, look at real work, ask how they handle tracking, testing and losing tests, and confirm who will do the work. Ask these eight questions on the first call; the answers sort the good from the rest.
Can I see real work? A sample audit or test plan tells you more than a sales call. Look for the evidence behind each recommendation.
Tell me about tests that lost. Every experienced consultant has plenty. Someone who only talks about wins is either new or selective.
How would you check my tracking? If the answer is vague, their findings will rest on numbers nobody has verified.
What do you measure a win by? It should be revenue, orders or qualified leads. A lift in clicks on a button is not a result by itself.
How do you decide when a test is done? They should mention sample size and significance, decided before the test starts. The statistical significance calculator shows the arithmetic.
Who will I actually work with? With a solo consultant it is them. With a consultancy, check that the senior person on the sales call is the one doing the work.
What do you need from me? A good consultant is clear about access, developer time and how fast changes need to ship. If they need nothing from you, nothing will change.
Have you worked on a site like mine? A store, a lead generation site and a SaaS product lose visitors in different places. Ask for a case study close to your situation.
Red flags when hiring a CRO consultant
A promised lift before they have seen your data. Nobody can know it in advance.
A redesign as the first recommendation. A full redesign changes everything at once, so nobody learns which change mattered.
"Best practices" with no evidence from your site. What worked elsewhere is a hypothesis for you, not a fix.
Tests called after a few days because the graph looks good. Early leads often fade. A test ends when it reaches the sample size set at the start.
Reports that show only conversion rate. A higher conversion rate with smaller orders can mean less revenue.
A black box. If you cannot see the test setup, the raw numbers and the reasoning, you cannot check the result.
A senior seller and a junior doer. Fine if you know about it, a problem if you find out later.
What does good CRO consulting look like?
Good CRO consulting keeps one ranked list of what to work on, checks every test before launch, and reads results honestly, including the losses. Most wasted CRO budgets fail at one of these three, not for want of ideas.
How an engagement usually runs
Tracking check and audit. You come out with a prioritized list of problems, and know which are clear fixes and which need testing.
Clear fixes go live. Broken steps and obvious friction get fixed without waiting for a test.
The first tests launch, each with its sample size and duration set in advance.
Results come in and the list is re-ranked. What a test teaches shapes the next one.
Most failed tests were decided before launch. A good consultant checks every line of this list.
The hypothesis names the problem, the change and the evidence behind it.
One primary metric is chosen in advance, tied to revenue, orders or qualified leads.
Guardrail metrics are named, such as average order value or refund requests, so a "win" that hurts the business is caught.
The sample size and the stop date are set before launch and cover full weeks.
The variation has been checked on real phones and browsers, with tracking firing on both versions.
Reading results honestly
An inconclusive test is a result: the change did not matter much, which frees the team to try something bigger. Good consulting also reports more than one number. In Convertica's dScryb case study, paid membership sign-ups rose 49.4% and revenue per visitor rose 23.8% in the same 17-day test. Both are true, and the decision depends on which one the business needs. Over a few months, your team should get better at spotting a weak test on its own.
How much does a CRO consultant cost?
A CRO consultant's cost depends on how they charge, how experienced they are and how much of the work they cover. They charge in one of three ways.
How CRO consultants charge
Model
How it works
Suits
Hourly
You pay for time used
Short questions and second opinions
Per project
A fixed fee for a defined piece of work, such as an audit
Getting a clear answer to "what should we fix"
Retainer
A fixed fee for ongoing direction
Teams running tests continuously
Many consultants do not publish their rates, so compare what each quote includes: whether test setup review and results analysis are part of it, who does the work, and how often you can reach them. A badly set up test wastes weeks of traffic whatever the fee. Convertica's standard prices are public: the CRO audit is free, a one page rebuild costs $497 and a full site rebuild $1,997. A retainer on a bespoke campaign is quoted one by one.

Most rebuilds take a couple of days, 7 days at most from the day we have access to your site.
A newer question for any CRO consultant: AI agents
More product research now starts in an AI assistant, and some assistants browse and act for a person. Ask a conversion optimization consultant whether they check that those agents can read your prices, stock and policies without running scripts, and that your robots rules do not block the AI crawlers you want. Agent readiness is one of the eight checks in Convertica's free CRO audit, and the agent readiness checklist lists what to look at. This is a young field with little long-term data, and we say so.

Rated 5 out of 5
Perhaps the best CRO company in the biz.
Scientific approach, testing is methodical, and changes are pragmatically made, based on reliable data.
Process is also very quick, only takes a few months in order to ramp up conversion rates and make better use out of existing traffic.
Kurt made it easy to understand what I was getting involved in, and Ayumi was very professional in handling the campaign thereafter.
A CRO consultant is a conversion rate optimization specialist who finds out why a website's visitors do not buy, sign up or get in touch, and directs the fixes and tests that address it. Hire one when you have steady traffic and someone to build changes, and judge them by real work and how they handle losing tests.
Key takeaways
Hire one when you have steady traffic, someone who can build changes and no clear answer to why visitors do not convert.
Consultant, expert and specialist describe the same work; judge the person by real work and how they handle tracking, testing and losing tests.
Be wary of anyone who promises a lift before they have seen your data.
Good consulting keeps one ranked list, checks every test before launch and reads results honestly, including the losses.
Convertica's standard offers are a free audit and fixed-price rebuilds of one page or a whole site; ongoing consulting is available on some bespoke campaigns.
CRO consultant FAQ
What does a CRO consultant do?
A CRO consultant finds why website visitors are not converting and directs the fixes and tests that address it. They check the tracking, audit the site, rank what to change, review each test before launch and read the results. They usually advise and plan, and your team builds the changes.
What does CRO stand for?
In marketing, CRO stands for conversion rate optimization: improving the share of visitors who buy, sign up or get in touch. The same letters also mean contract research organization in medicine and Chief Revenue Officer in sales, which is why some search results for CRO consultant are about clinical trials.
What is the difference between CRO and CRM?
A CRO consultant works on conversion rate optimization: getting more of a website's visitors to buy, sign up or get in touch. CRM, customer relationship management, is the practice and software for managing leads and customers after they convert, such as contact records and sales pipelines. A CRO consultant improves the site; a CRM consultant sets up the system behind it.
How much does a CRO consultant cost?
It depends on the model: hourly, per project or an ongoing retainer, and rates vary with experience and scope. Many consultants do not publish their rates, so compare what each quote includes. Convertica's standard offers have fixed prices, listed on the pricing page; a retainer on a bespoke campaign is quoted one by one.
Should I hire a CRO consultant or a CRO agency?
Hire a consultant if you have people who can build changes and you need direction. Hire an agency if you need the whole team supplied. If you need to know what to fix on a page and want it built for a fixed price, Convertica's free CRO audit and its rebuilds are a third route.
Does Convertica offer CRO consulting?
On some bespoke campaigns, quoted one by one as a bespoke proposal. Its standard offers are a free CRO audit, a one page rebuild and a full site rebuild of the whole site. In a rebuild, Convertica's team builds every fix the audit found.
How long does it take to see results?
It depends on traffic. Clear fixes can show up quickly. A/B test results take longer, because each test has to reach the sample size set before it started, and lower-traffic sites need longer per test.
What tools does a CRO consultant use?
Usually an analytics tool such as Google Analytics 4, a heatmap and session recording tool, an A/B testing tool, a form analytics tool and a survey tool. Past Convertica case studies used VWO for testing and Formisimo for form analytics.
What is a CRO expert?
A CRO expert is someone who improves the share of a website's visitors who buy, sign up or get in touch. It is the same work as a CRO consultant or a CRO specialist: consultant usually means someone advising several companies, specialist is the common job title, and expert is how either describes themselves.
What is fractional CRO?
Fractional CRO usually means a part-time Chief Revenue Officer, a sales leadership role. In conversion work, a fractional CRO consultant is a senior conversion specialist who works with you part-time on an ongoing basis, which is the same as a CRO consulting retainer.
