CRO services for e-commerce are specialist agencies, consultancies, and platforms that identify where your store is losing revenue and implement the changes to recover it. If you want a working definition of what CRO actually involves before reading this list, our guide to what conversion rate optimisation is covers the fundamentals.
Here is a pattern I see constantly when a founder asks me to recommend a CRO service. The first question is always: who is the best? The better question is: best for what? A premium research-led agency charging £15,000 a month is the wrong fit for a business with 30,000 monthly visitors. A Shopify-specialist agency is the wrong fit for a B2B SaaS sign-up funnel. The wrong fit is expensive regardless of the service's quality.
Most of the noise in this category comes from agencies that describe their process better than they execute it. The ones worth hiring have a research phase before they touch a test, are accountable to revenue outcomes rather than test volume, and have senior people doing the actual work.
This list covers nine services worth knowing in 2026, across e-commerce, SaaS, DTC, B2B, and lead generation. Where a service is genuinely strong in one model and less so in another, I say so. Use it as a shortlist, not a ranking.
Comparison of 9 CRO services for online businesses in 2026, mapped by business model fit, budget range, and research depth.
1. Precision Consulting
This is my consultancy, so I will describe it the way I would to a founder asking me directly rather than the way a website does it. Most CRO engagements start with a list of things to test. Precision engagements start with a diagnosis: figuring out what is actually causing the conversion problem before anything is changed or designed. That sequence matters because most businesses are not losing revenue for the reason the founder thinks they are. I lead the work throughout. No handoff after the onboarding call, no project manager in between. You can see the full scope on the services page.
The background is over a decade of running growth and product functions across major tech platforms in MENA and APAC, across 15 or more markets. On GrowthMentor, the rating is 4.9 out of 5 across over 90 sessions with founders across e-commerce, SaaS, and DTC.
The ethical position is explicit because I think it matters: no dark patterns, no manufactured urgency, no deceptive design. Businesses earn more by building better experiences than by manipulating users into converting. That is not a marketing line. It is how the work is actually done.
Best suited for
Founders at the growth stage who have tried generic CRO advice and found it does not translate to their specific funnel. Particularly relevant when the conversion problem is in the UX and experience layer, not just the copy or the ads.
Not the right fit if
You need a large team running parallel experiments across dozens of pages simultaneously. This is a boutique practice. The value is depth and specificity. If volume is the primary requirement, one of the larger agencies on this list is a better match.
Pricing
Services start from the mid three figures. Engagements are scoped to the business.
2. Conversion Rate Experts
Conversion Rate Experts has been in this industry longer than most, and their methodology is genuinely rigorous. Not rigorous in the way every agency claims. Rigorous in the sense that they run extensive user interviews, produce detailed findings reports, and document their reasoning at every stage. Their case studies are public and specific. That is unusual.
The tradeoff is time and cost. Before a single test ships, there is a research phase that most businesses find takes longer than they expected. If you are a growth-stage business that needs a quick win on the checkout or product page, this is the wrong service. If you are a mature brand with meaningful revenue and you want a definitive answer about what is actually wrong with your funnel, it is the right one.
Best suited for
Established businesses with significant revenue that have already done the basic CRO work and need a research-led programme at a level of rigour that most agencies do not operate at.
Not the right fit if
You need to move fast or have a limited budget. The minimum engagement cost is typically £10,000 or more per month. The research phase before the first results is measured in weeks, not days. Worth it for the right business. Not worth it if you need a result before the quarter ends.
Pricing
Enterprise pricing. Typically starting at £10,000 to £15,000 per month with minimum engagement periods.
3. SplitBase
SplitBase is Shopify and Shopify Plus. If your business runs on a different platform, they are not the right fit. If it does run on Shopify, the platform-specific depth matters more than most founders realise. Generalist CRO agencies often work around Shopify's constraints rather than inside them. SplitBase builds inside them.
The focus is on landing pages and product pages, with a mobile-first approach. The work is design-led: hierarchy, CTA clarity, and how the offer reads on a phone screen. This is appropriate when the conversion problem is in the page experience. It is less the right choice when the friction is deeper in the funnel, the checkout flow, or the post-purchase sequence.
Best suited for
DTC brands on Shopify or Shopify Plus with paid social traffic and a landing page or product page conversion problem. Particularly strong for businesses where the ad is working but the page is not converting the traffic it sends.
Not the right fit if
Your conversion problem is in the checkout, the cart, or deeper in the funnel. The landing page specialisation is a strength in the right context. In the wrong one, you are paying for expertise that does not map to where your revenue is leaking.
Pricing
Retainers typically range from $5,000 to $15,000 per month based on published market data, depending on scope and brand size. SplitBase typically works with established DTC brands rather than early-stage stores.
4. Speero by CXL
Speero is the agency arm of CXL, one of the most respected training and research organisations in the CRO industry. The approach is rigorous and data-heavy: structured research frameworks, prioritised test roadmaps, and documented learning cycles. If the CXL blog is familiar to you, Speero operates with the same intellectual rigour in practice.
The model is built around the ResearchXL framework, which covers analytics, user testing, qualitative research, and heuristic evaluation before a test is designed. This produces well-founded hypotheses and reduces the probability of running tests that are theatrically correct but strategically irrelevant. The tradeoff is that the programme takes time to build properly and requires a business with enough traffic to run experiments at statistical validity.
Best suited for
Businesses with meaningful traffic volumes and the patience for a research-led programme. Works well for e-commerce businesses that want to build an internal experimentation capability alongside the agency work.
Watch out for
Programme depth requires traffic volume to be meaningful. Below roughly 100,000 monthly sessions, some of the experimentation rigour becomes impractical. The model is also more oriented toward tech and SaaS than pure e-commerce, so confirm the team's e-commerce depth before engaging.
Pricing
Project and retainer-based. Pricing varies by programme scope. Custom quotes available on their website.
5. Invesp
Invesp sits in the middle of the market: more accessible than enterprise agencies, more structured than freelance CRO work. The process covers heuristic evaluation, analytics analysis, and A/B test execution across the full funnel. The 15-year track record across e-commerce, SaaS, and lead generation means the methodology is tested across a wide range of business types and funnel structures.
The breadth is also the thing to pressure-test. Fifteen years across many industries means broad coverage. It does not automatically mean deep expertise in your specific category. Ask for case studies in your business model before engaging, not just their headline results.
Best suited for
Mid-market online businesses past the startup stage that want a structured full-funnel CRO programme without enterprise pricing.
Not the right fit if
You need senior-level involvement throughout the engagement. Confirm who will be on your account week to week before signing. At mid-market price points, account management quality varies. Ask directly.
Pricing
Retainers typically run $7,000 to $15,000+ per month based on published data. Clutch reviewers report total engagement investments in the $30,000 to $60,000 range for multi-month programmes.

6. Hotjar
Hotjar is a behaviour analytics platform, not an agency. It gives your team visibility into how real users interact with your site: heatmaps showing where attention lands and where it does not, session recordings of actual user journeys across e-commerce, SaaS, and lead generation funnels, and survey tools for collecting qualitative feedback at specific funnel points. The data it surfaces is often the starting point for any serious CRO programme.
The free tier covers the basics for smaller sites. Paid plans start at around $32 per month and unlock higher session recording volumes and more detailed heatmaps. If you are running a CRO programme without behaviour analytics, you are designing tests based on assumptions rather than evidence. That is not a harsh standard. It is the practical minimum.
Best suited for
Any online business that wants to understand how real users are behaving before engaging an agency or designing tests. Useful as a starting point for founders who want to diagnose their own funnel before deciding what kind of specialist they need.
One thing to be clear about
Hotjar tells you what is happening. It does not tell you why, and it does not run tests. Session recordings require someone who can translate what they are seeing into a hypothesis. Without that interpretation layer, the data sits in a dashboard and nothing changes.
Pricing
Free tier available. Paid plans range from approximately $32 per month. Business plans from $80 per month for higher volume and advanced features.
7. VWO (Visual Website Optimizer)
VWO is an A/B testing and conversion optimisation platform that gives in-house teams the infrastructure to design, run, and analyse experiments without heavy technical resources. It covers split testing, multivariate testing, personalisation, and session recordings in a single platform. If you are building an internal experimentation function, our article on A/B testing for e-commerce founders covers how to structure the programme before you invest in the tooling.
The platform is more enterprise-oriented than some alternatives, which is reflected in the pricing and the feature depth. For businesses running a high volume of tests across multiple pages and audiences, the sophistication is appropriate. For smaller stores running occasional tests, the cost-to-benefit ratio may not justify the investment over simpler alternatives.
Best suited for
Mid-market to enterprise e-commerce businesses with in-house CRO or product teams that need robust testing infrastructure. Businesses that are running more than a handful of tests per quarter need proper statistical controls and reporting.
Watch out for
Platform access does not substitute for test design expertise. Running the wrong tests with excellent tooling produces confident but wrong conclusions. Pair VWO with a structured testing methodology, not just an instinct about what to change.
Pricing
Plans range from approximately $300 per month for small businesses. Enterprise pricing for high-traffic stores. Free trial available.
8. Klientboost
Klientboost is a performance marketing agency with a strong CRO component focused on landing page optimisation in the context of paid traffic. They work across e-commerce, SaaS, and lead generation, with particular strength in the ad-to-landing-page conversion step. If you are spending meaningfully on Google Ads or Meta and your pages are not converting at a rate that justifies the spend, the integrated approach is relevant.
The agency is known for speed and volume of testing rather than deep research. They move quickly, ship iterations fast, and measure results against ad performance metrics. This is appropriate for businesses where the primary problem is ad-to-page conversion. It is less suited to businesses where the conversion problem is deeper in the funnel or requires the kind of UX and behavioural analysis that takes longer to surface.
Best suited for
Online businesses that are spending significantly on paid acquisition but are losing conversions on the landing page. Works best when the ad strategy and landing page optimisation are managed in coordination.
Watch out for
Speed-first testing can produce short-term wins that do not compound. Confirm their approach to statistical validity and test duration before engaging. Fast iteration without proper controls produces noise, not signal.
Pricing
Entry-level engagements run $2,500 to $4,000 per month for smaller accounts. For businesses with larger budgets or multi-channel requirements, costs scale significantly beyond that range. Minimum ad spend thresholds typically apply.
9. Webprofits
Webprofits is a growth agency that covers digital marketing, UX, and CRO as part of an integrated growth model, working across e-commerce, DTC, and SaaS. The CRO work sits alongside paid traffic, content, and analytics in a broader programme, which is useful for businesses that need multiple growth levers coordinated rather than CRO as a standalone engagement.
The agency has a strong track record in e-commerce and DTC and a methodology that links conversion work directly to revenue outcomes. The integrated model is a strength if you need multiple disciplines coordinated. If your sole need is deep CRO and UX work, a specialist is likely a better fit than a multi-disciplinary agency.
Best suited for
Growth-stage online businesses that need traffic, CRO, and analytics to move together. Useful for founders who do not want to manage multiple agency relationships and prefer a single partner across the growth function.
Watch out for
Multi-service agencies tend to have variable depth across disciplines. Confirm who is leading the conversion work specifically and what their background is before signing. An agency-wide track record in growth does not guarantee deep CRO expertise in every team.
Pricing
Pricing is not publicly available. No reliable benchmark data exists for total engagement costs. Request a quote directly via their website.
How do you evaluate a CRO service before you commit?
Decision guide for choosing a CRO service: four questions to ask any agency or consultancy before signing, with what each answer tells you.
The right CRO service depends on four variables: your traffic volume, your business model, your in-house capability, and the depth of the problem you are trying to solve. Whether you are running an e-commerce store, a SaaS product, a DTC brand, or a B2B lead generation site, the diagnostic process is the same. Before engaging any service on this list, run through the CRO audit checklist yourself. It takes 60 minutes and will tell you which parts of your funnel are the highest-priority problems. Showing up to a scoping call having done that work changes the conversation significantly.
Four questions to ask every service on this list before you engage:
- What does your research process look like before you design a test?
- Who will be on my account week to week, and what is their background?
- Can you show me case studies from businesses at my stage and in my category?
- What does a failed test look like in your process, and what happens next?
Most agencies will answer the first question smoothly. The second and third are where you learn something. If the answer to who is on your account is vague, that means a senior person pitches and a junior person executes. If the case studies are all from a different industry or a different scale of business, the pattern recognition that drives good hypothesis design does not transfer.
The fourth question is the most revealing. A service that has never had a test fail has either not been running tests for long or is not telling you the full story. Failed tests are where the learning compounds. How a team processes a null result tells you more about their methodology than any winning test they can show you.
- CRO services split into two categories: agencies and consultancies that do the work for you, and platforms that give your team the tools to do it. The right choice depends on your business model, in-house capability, and the nature of the problem.
- Deep research before testing is the single biggest differentiator between CRO services that produce durable results and those that produce short-term wins that evaporate. Ask every agency what their research process looks like before a test is designed.
- Traffic volume determines which services make sense. Structured experimentation programmes require enough traffic to reach statistical significance. Below 10,000 to 20,000 monthly sessions, the priority is fixing obvious friction, not running tests.
- Behaviour analytics tools like Hotjar are a prerequisite for serious CRO work, regardless of business model. Without visibility into how real users are behaving on your site, any conversion work is based on assumptions.
- Multi-disciplinary agencies offer coordination benefits but may lack the depth of a specialist. If your primary need is conversion work, confirm the background and seniority of the specific team that will be on your account.
- Ask for case studies from businesses at your stage and in your category. A track record with enterprise brands does not predict results for a growth-stage DTC business, and vice versa.
- The four questions that reveal agency quality: What is your research process before designing a test? Who is on my account week to week? Can you show me relevant case studies? What does a failed test look like in your process?
Frequently asked questions
What are CRO services for e-commerce?
CRO services are agencies, consultancies, and platforms that help online businesses increase the percentage of visitors who complete a desired action. That action might be a purchase on an e-commerce store, a trial sign-up for a SaaS product, a form completion on a B2B lead generation site, or a subscription for a DTC brand. The work typically includes diagnosing where visitors are dropping off, identifying the friction causing the drop-off, and designing and testing changes to remove it.
How much do CRO services cost?
CRO agency retainers typically range from $2,000 to $15,000 or more per month, depending on programme scope and agency seniority. This range applies across e-commerce, SaaS, and B2B engagements. Behaviour analytics platforms like Hotjar start from free. A/B testing platforms like VWO start from approximately $300 per month. Specialist consultancies are typically scoped to the engagement. The right investment depends on your revenue, traffic volume, and the size of the conversion opportunity.
When is a business ready for CRO services?
A business is typically ready for a structured CRO programme when it has at least 10,000 monthly visitors, consistent traffic from a reliable source, and a clear sense of where the biggest conversion leakage is occurring. This applies across business models: e-commerce stores losing buyers at checkout, SaaS products losing trial sign-ups at the pricing page, and B2B sites losing leads at the contact form. Below that threshold, the priority is fixing obvious friction. Above it, a structured programme starts to compound meaningfully.
What is the difference between a CRO agency and a CRO consultancy?
A CRO agency typically operates a team model with project managers, analysts, designers, and developers executing a programme. A CRO consultancy is usually smaller and more senior-led, with a founder or specialist doing the diagnosis and the strategic work directly. Agencies offer scale. Consultancies offer depth and direct access to the person accountable for the work.
How do I know if a CRO service is worth hiring?
Ask for case studies from e-commerce businesses at a similar stage and in a similar category to yours. Ask specifically about their research process before a test is designed. Ask who will be on your account week to week. A CRO service that cannot answer these questions with specificity is worth treating with caution, regardless of the testimonials on their homepage.
The nine services on this list represent a genuine range, from enterprise research agencies to behaviour analytics tools to boutique consultancies. The right choice is the one that maps to where your business actually is, not where you would like it to be.
