TL;DR
- CRO is a continuous cycle, not a one-time project.
- Choosing a Shopify CRO agency is about finding a team that can identify where revenue is leaking, prove why it is happening, test the fix, and implement what works across the entire path to purchase.
- This ranking evaluates 10 Shopify CRO agencies based on their documented CRO results, Shopify expertise, research methodology, implementation capabilities, testing approach, and client fit.
- The strongest teams connect conversion rate optimisation to measurable business outcomes such as conversion rate, average order value, revenue per visitor, and customer loyalty.
Key takeaways
- In our review, craftberry ranks first for combining CRO research, A/B testing, Shopify Plus engineering, and implementation within one in-house team.
- CRO works best when testing and implementation stay connected. Winning changes can be shipped faster when the same team handles research, test execution, development, and QA.
- The strongest CRO programs focus on revenue, not conversion rate alone. Revenue per visitor, average order value, retention, and customer loyalty can show business impact that conversion rate alone misses.
- Shopify CRO pricing varies widely by scope. Published market pricing reviewed for 2026 ranges from roughly $500 to $8,000 for audits and $2,000 to $10,000+ per month for ongoing CRO, with enterprise programs reaching $20,000+ per month. craftberry's own CRO retainer starts around $3,500 per month.
What is a Shopify CRO agency?
A Shopify conversion rate optimization agency helps Shopify store owners get more value from the website visitors and traffic their online store already receives.
Instead of focusing only on acquisition and ad spend, an ecommerce conversion rate optimization agency identifies where shoppers drop out, investigates user behaviour, and tests changes designed to increase conversion, average order value, revenue per visitor, or retention.
In practice, CRO agencies optimize the entire path to purchase on Shopify, from product discovery and landing pages to checkout and post-purchase experience.
The goal is not simply to convert more visitors. It is to help Shopify store owners generate more value from existing traffic, improve customer experience, and reduce the cost of acquiring each customer.
A strong Shopify CRO program typically combines:
- Analytics and funnel analysis
- Session recordings and heatmaps
- Customer reviews, surveys, and support data
- UX and merchandising audits
- Hypothesis prioritization
- A/B testing
- Shopify development
- QA and implementation.
A strong CRO program follows a strategic process and a continuous cycle:
Platform-specific expertise matters because the bottleneck may not be a landing page or CTA. It can be product discovery, site speed, theme performance, checkout extensibility, app conflicts, or custom functionality.
Shopify's current checkout documentation shows that advanced checkout customizations and certain UI extensions are available specifically to Shopify Plus merchants
A CRO agency that can identify the problem but cannot implement the solution still leaves you with a handoff.
How we ranked the best Shopify CRO agencies
We ranked the agencies using five criteria weighted by their impact on a CRO program's ability to produce measurable results. The criteria also help distinguish a Shopify CRO agency from a broader ecommerce CRO agency, where platform expertise and implementation capabilities can vary significantly.
| Criterion | Weight | What we looked at |
|---|---|---|
| Verifiable published CRO results | 30% | Named client outcomes with enough context to understand what changed and what was measured, not a logo wall. |
| Implementation capability | 25% | Whether research, design, development and QA sit on one team, so a winning test ships without a handoff |
| Platform specific expertise | 20% | Shopify partner status and real, demonstrated use of Shopify Plus capability such as checkout extensibility |
| Testing discipline and transparency | 15% | A stated research process, a stated approach to statistical significance, and honesty about losing tests |
| Access and fit clarity | 10% | Published pricing or engagement model, and a clear view on who the agency is not right for |
Results carry the heaviest weight because documented client outcomes provide the most concrete evidence available for comparing CRO capabilities.
We looked at publicly verifiable evidence rather than agency claims alone. We gave more weight to documented mechanisms and outcomes than to headline percentages, logo counts, or broad service claims.

Ranking note: Our assessment is based on evidence that agencies make publicly available, including their websites, case studies, pricing information, and published CRO results.
We evaluated what each agency could demonstrate rather than relying on claims or information that was not available for review.
Results published by the agencies themselves are treated as reported outcomes, not independently validated performance data.
1. craftberry
/)
craftberry combines conversion rate optimization with Shopify Plus expertise and in-house development, design, and engineering.
The team has over 11 years of Shopify experience and has delivered 800+ Shopify projects since 2015, including migrations from platforms such as WooCommerce and Magento.
Its CRO work includes documented A/B tests across Mi Amante, Enhance Auto, Carista, Shelly, and others.
The key difference in the operating model is in-house implementation.
The team running the CRO work can also modify the theme, improve page speed, rebuild product discovery, or work with Shopify Plus capabilities when the test requires more than a front-end change.
For Mi Amante, a recognisable haircare brand, craftberry runs a comprehensive CRO program. With an 80% account-level win rate across five concluded tests in the first half of 2026, the program combined a structured audit, customer and behavioural research.
The results included:
| Test | Result |
|---|---|
| Product-page upsell improvement | Conversion +11.1%, RPV +13.8% |
| Collection-page colour swatches | Conversion +4.0%, RPV +7.3% |
| Mobile menu rebuild | Conversion +2.7%, RPV +5.5% |
The upsell improvement test was focused on clear quantity tiers, total price, per-unit price, savings, and a "Most Popular" recommendation to increase average order value.
The test reached a 97.4% probability of beating control.
craftberry also developed Signal Veritas, its proprietary CRO intelligence tool. It combines behaviour analytics, heatmaps, and survey insights to help turn raw customer behaviour into prioritized testing hypotheses.
/)
The testing stack includes CRO tools such as Intelligems for A/B testing and tools such as Microsoft Clarity for session recordings and heatmaps.
"All of our deliverables were provided on time unless otherwise communicated, and their responses were prompt."
Richard Krolikowski, E-Commerce Consultant, Midi Health. Clutch review
Best for: Shopify and Shopify Plus brands that need CRO strategy and implementation from the same team.
Less suitable for: brand-new or very small stores, or companies looking only for a one-off audit without implementation.
2. SplitBase
/)
SplitBase is a CRO-focused agency built around ongoing experimentation for larger DTC brands.
Its strongest fit is enterprise ecommerce teams that already have development resources and want a specialist experimentation partner.
The trade-off is implementation. Because the agency does not own the entire storefront build, technical issues involving speed, catalogue architecture, or deeper Shopify development may require another team.
Best for: established 8- and 9-figure DTC brands with internal development capability.
Less suited for: brands that want one partner to handle both CRO testing and Shopify development.
3. Blend Commerce
/)
Blend Commerce combines Shopify-focused CRO with analysis, strategy, design, and development.
Blend publishes a typical best-fit profile of £2m+ in annual revenue and 50,000+ monthly sessions, and states that strategy, UX, Shopify development, A/B testing, and QA are handled in-house.
Best for: established Shopify stores with enough traffic to support structured experimentation.
Less suited for: lower-traffic Shopify stores without enough volume to run statistically significant tests.
4. Conversion Rate Store
/)
Conversion Rate Store works across ecommerce and SaaS rather than focusing exclusively on Shopify.
Its positioning places a strong emphasis on data, research, and structured experimentation. That makes it relevant for businesses with complex analytics requirements or a need for a broader CRO program.
One distinctive part of its commercial model is performance-based pricing, where fees can be tied to the uplift produced rather than relying only on a fixed CRO retainer.
The main consideration for Shopify merchants is platform depth. Ask which team members have directly implemented and shipped CRO changes inside Shopify themes and Shopify Plus environments.
Best for: businesses looking for research-led CRO across multiple platforms.
Less suited for: brands looking for a Shopify-only partner with deep Shopify Plus implementation expertise.
5. Fuel Made
/)
Fuel Made combines Shopify Plus services with CRO, email, and customer retention.
Its CRO offering includes both one-time audits and ongoing retainers that can combine experimentation with design and development, while its wider service mix also covers Klaviyo email and SMS.
That combination can make sense when conversion problems overlap with retention problems. For example, improving the first purchase experience may not be enough if the post-purchase journey creates friction.
Best for: Shopify brands that want CRO alongside retention and lifecycle marketing.
Less suited for: brands with primarily structural or technical conversion issues, rather than retention or lifecycle challenges.
6. Electric Eye
Electric Eye combines Shopify development with optimization work. Its approach can suit brands that want CRO improvements alongside broader storefront development.
Brands can also begin with a fixed-fee Shopify Diagnostic designed to identify conversion and storefront opportunities before moving into broader optimization or development work.
For brands prioritising structured experimentation, it is worth comparing testing depth, implementation scope, and reporting across providers.
Best for: Shopify brands that need optimization alongside broader store development.
Less suited for: brands looking for a dedicated, high-volume A/B testing program.
7. Conversion Fanatics
Conversion Fanatics focuses on structured experimentation and conversion optimization across ecommerce businesses rather than operating as a Shopify-only agency.
The agency places particular emphasis on testing velocity, citing more than 35,000 split tests across 350+ companies and stating that it does not cap the number of tests run per month.
Its broader ecommerce experience can be useful for brands that want structured experimentation without restricting the work to one platform.
Best for: ecommerce businesses looking for a dedicated testing program across platforms.
Less suited for: brands that need deep Shopify Plus expertise from a platform-focused partner.
8. GrowthHit
GrowthHit combines CRO with acquisition and retention marketing.
Its model brings Meta and Google advertising, onsite conversion work, and lifecycle email and SMS into the same broader growth program rather than treating CRO as an isolated service.
That broader scope can work well when you want one partner across the funnel rather than a standalone CRO team.
The main question is allocation. Ask how much of the engagement is dedicated to structured experimentation versus paid acquisition, lifecycle marketing, and other growth activities.
Best for: brands looking for CRO as part of a broader growth-marketing program.
Less suited for: brands looking for a dedicated CRO team focused primarily on structured testing.
9. Avex Designs
Avex works with Shopify Plus brands across design, personalization, and experimentation.
Its experimentation offering also extends into more advanced personalization through Dynamic Yield, with optimization delivered as part of its ongoing Growth-X model.
Its approach is relevant for businesses looking beyond basic A/B testing toward more advanced personalization.
Best for: Shopify Plus brands with personalization requirements.
10. Shero Commerce
A Shopify Plus agency combining UX, development, and optimization.
Shero is a Shopify Premier Partner and combines funnel analysis, behavioural research, A/B testing, UX, and Liquid development within its ongoing optimization work.
Its combination of UX and Shopify development can reduce handoffs when optimization work requires technical implementation.
Best for: Shopify Plus brands that need development and UX alongside conversion optimization.
Less suited for: brands that are not on Shopify Plus or want to compare pricing before starting a conversation.
What actually moves conversion on Shopify?
A CRO program should not start with a list of generic best practices. It should start with the specific friction costing your customers a sale and the customer experience problems behind it.
Recurring patterns we have seen with client testing at craftberry
1. Placement can matter more than adding features
On Enhance Auto, a brand that works with craftberry, creator reviews already existed on the product page. The problem was placement. They sat below the point where many shoppers made their decision.
Moving the reviews directly below the hero and improving the thumbnails increased conversion by 21.01% and revenue per visitor by 21.63% in a four-week test.
Nothing new was added. The existing asset was simply placed where shoppers could use it.
2. Merchandising can increase revenue without changing price
On Shelly, another craftberry client, the store sold single units, 2-packs, and 4-packs without clearly guiding customers toward the larger quantities.
Adding "Most Popular" and "Best Value" labels increased conversion by 11% and revenue per visitor by 8%. The price and layout stayed the same.
The lesson is practical: before adding another feature, check whether your existing offer is being framed clearly enough.
3. Product discovery becomes critical as catalogues grow
Large catalogues create a different CRO problem. Shoppers do not necessarily need more choice. They need to find the right choice faster.
On Shawty Active, fashion brand working with craftberry, clearer filtering and an editorial collection structure increased conversion by 9% and AOV by 4%.
For large Shopify catalogues, search terms, filtering, collection architecture, and merchandising can have more commercial impact than homepage redesigns.
Product discovery is not simply a UX issue: if shoppers cannot find the right product quickly, more visitors do not necessarily translate into more revenue.
4. Speed is a revenue lever
Site speed and Core Web Vitals should be part of CRO when technical speed issues affect the customer journey, particularly on mobile.
Independent research commissioned by Google and conducted by Deloitte found that a 0.1-second improvement in mobile site speed was associated with an 8.4% increase in retail conversions and a 9.2% increase in average order value.
Our own Shopify case studies at craftberry show how technical improvements can translate into measurable commercial results.
- After migrating Pro Energetic to Shopify Plus and optimizing backend code, page load times improved by 43% and returning customers increased by 38%.
- On Carpet Warehouse, moving from headless architecture back to native Shopify Plus improved LCP by 55% and conversion by 8%.
Headless is not inherently better for conversion or customer experience.
The right architecture is the one that delivers the required experience without adding technical complexity that does not improve business performance.
"They don't feel like an agency, but rather part of a team that is just as invested in our company's success as we are."
Michael Silva, VP E-Commerce & DTC Marketing, Honest Baby Clothing. Clutch review
An actual CRO example from the kitchen
A core CRO principle we have seen at craftberry: one test can produce a useful result, but a structured testing program can compound several improvements across the customer journey.
Mi Amante shows why CRO works better as a program than as a collection of isolated tactics.
The initial research identified several different friction points. The product-page upsell lacked clear hierarchy. Customers needed more clarity when choosing colours. Mobile navigation needed improvement on a store where 95.6% of sessions were mobile.
/)
The resulting tests produced three separate conversion gains:
- +11.1% from the product-page upsell redesign
- +4.0% from collection-page colour swatches
- +2.7% from the mobile menu rebuild
The first test also increased revenue per visitor by 13.8%.
Mi Amante's program runs on Signal Veritas, craftberry's proprietary CRO intelligence tool, alongside Intelligems for A/B testing and Microsoft Clarity for behavioural analysis.
/)
Signal Veritas helps connect customer behaviour data, customer reviews, and analytics, to testable hypotheses.
What does a Shopify CRO audit include?
A proper Shopify CRO audit should answer two questions:
- Where are shoppers dropping?
- Why are they dropping there?
That requires more than a funnel report or basic analytics setup.
We combine three data streams in every craftberry CRO audit:
Data analysis: funnel performance, device performance, traffic source, product and checkout behaviour.
UX audits: mobile and desktop experience, navigation, merchandising, product pages, cart, and checkout.
UX improvements can affect commercial metrics well beyond conversion rate, including average order value, retention, and bounce rate. The impact depends on the problem being solved, which is why UX audits should lead to testable hypotheses rather than generic redesign recommendations.
Customer voice: reviews, surveys, support conversations, and other direct customer feedback.
The three sources are then cross-checked against real data before hypotheses are prioritized.
"The craftberry team was very responsive and understood our brand well after the discovery phase."
Daniel Medina, CEO, Sana Vidal. Clutch review
This matters because the funnel may show that shoppers are abandoning checkout, while customer feedback reveals that shipping costs are the actual problem.
Baymard's checkout research found that unexpected extra costs were the leading reason for cart abandonment, while a checkout that was too long or complicated was another major source of friction.
The value of this approach is that it connects the data to the underlying problem. The funnel may show that shoppers are abandoning checkout, while customer feedback reveals that shipping costs are the actual issue.
Analytics may show weak product-page conversion while reviews reveal that customers need information the page does not provide.
How much does Shopify CRO cost in 2027?
Pricing varies by traffic volume, testing velocity, technical scope, and whether development is included.
Based on publicly available CRO pricing reviewed in 2026, typical published ranges fall roughly into the following bands:
| Engagement | Typical range |
|---|---|
| CRO audit or diagnostic | $500 to $8,000 |
| Entry retainer | $2,000 to $5,000/month |
| Standard retainer | $4,000 to $10,000/month |
| Enterprise retainer | $10,000 to $20,000+/month |
| Performance-based CRO | Fee per uplift or revenue share |
These are directional market ranges synthesized from publicly available pricing reviewed in 2026, not verified invoices or independent industry benchmarks.
craftberry's own CRO retainer starts around $3,500/month, with development quoted separately.
The better question is not whether an agency costs $3,000 or $10,000 per month. It is whether the expected revenue impact justifies the investment.
For example, a store generating 200,000 monthly sessions at a 2% conversion rate receives roughly 4,000 orders. Increasing conversion to 2.5% would add 1,000 orders without buying additional traffic or attracting more visitors.
The value of CRO depends on your own economics.
When does Shopify CRO make sense?
Traffic volume and customer acquisition costs determine whether formal A/B testing is practical. This is particularly relevant for a consumer goods CRO agency, where purchase frequency, product margins, average order value, and traffic volume can vary significantly across categories.
craftberry's internal qualification threshold is roughly 1,000 monthly orders before recommending a structured A/B testing program. This is not an industry-wide rule. Different agencies use different traffic or revenue thresholds.
For a smaller store, user research, merchandising, technical fixes, and structural UX improvements may make more sense than running multiple formal experiments.
For newly launched stores, we generally wait around 1.5 to 2 months before starting structured experimentation, provided there is enough traffic and behavioural data to support meaningful testing. Testing too early can mean testing noise rather than a stable customer pattern.
Our 2026 CRO testing record
We publish the full result breakdown rather than one blended win rate.
| Account | Winners | Losers | Neutral | Test win rate |
|---|---|---|---|---|
| Mi Amante | 4 | 0 | 1 | 80% |
| Enhance Auto | 6 | 2 | 0 | 75% |
| Carista | 8 | 2 | 1 | 73% |
| Shelly | 4 | 7 | 1 | 33% |
| Combined | 22 | 11 | 3 | 61% |
Win rate is calculated as winning tests divided by all concluded tests, including neutral results. Excluding neutral results, the combined win rate is 67%.
The variation between accounts is important.
A 33% win rate on a mature store does not necessarily indicate poor CRO. It can mean the obvious opportunities have already been addressed. A higher win rate can reflect a newer testing program with more unresolved friction.
"Real CRO isn't a list of best practices, it's a graveyard of killed tests and a few winners you scale. Not every test wins, so the discipline is stopping the losers fast."
Preslav Nikov, founder of craftberry
Publishing losing tests gives the winning tests more context and shows how the testing process informs the next hypothesis.
What to ask a Shopify CRO agency before you sign
Ask these questions before choosing an agency:
Can you show me a test that lost?
A real testing program produces losers. Ask what the agency learned and what happened next.
What is your win rate by account?
A blended win rate can hide significant differences between clients.
Who handles test execution and production code?
If the CRO agency finds a winner but another vendor has to implement it, ask how that affects cost and timeline.
What happens in week one?
A strong answer should include analytics and tracking validation before test ideas.
What traffic floor do you require?
If an agency cannot explain how it determines statistical significance, be cautious.
How do you define a winner?
The primary metric and decision criteria should be established before the test starts.
Do you report revenue per visitor and average order value?
Conversion rate alone can hide the commercial impact of a test. Revenue per visitor and AOV provide a stronger view of business value.
When craftberry is not the right fit
craftberry is not the right choice for every business owner or Shopify store.
We generally do not recommend a formal CRO retainer for:
- Stores without meaningful post-launch data
- Very low-traffic stores where reaching statistical significance would be too time-consuming to justify a formal testing program
- Brand-new or hobbyist stores
- Businesses looking only for a one-off audit with no implementation
- Brands looking for guaranteed placement in AI answers
AI visibility cannot be bought or guaranteed. It is earned through useful, credible, well-supported content and first-hand evidence.
