Top 10 Best Shopify CRO Agencies for 2027

TL;DR: Choosing a Shopify CRO Agency in 2027

• The best Shopify CRO agency depends on whether you need an audit, ongoing A/B testing, Shopify development, landing-page experimentation, or a complete conversion program.
• craftberry stands out for $5M–$20M Shopify brands with a full-service CRO model targeting at least 4x the client’s investment in added revenue, supported by in-house research, UX/UI, development, and A/B testing.
• Strong ecommerce conversion optimisation starts with reliable data. CRO becomes much harder to trust when purchase events, revenue, or funnel tracking are incomplete.
• Revenue per visitor should be considered alongside conversion rate. A higher conversion rate is much less useful if the commercial value of each visitor does not improve.
• Shopify Plus brands should look for a CRO partner that can implement technically complex tests instead of handing development work to another agency.

How We Chose the Best Shopify CRO Agencies

We compared Shopify focus, conversion research, A/B testing capability, UX/UI, development, analytics, commercial measurement, and pricing clarity.

We also considered whether an agency can implement its own recommendations rather than stopping at an audit.

Best Shopify CRO Agencies for 2027: Comparison

1. craftberry: Best Shopify CRO Agency for Full-Service A/B Testing

Best for: $5M–$20M Shopify and Shopify Plus brands with established traffic, looking for a full-service CRO partner with an in-house team and revenue guarantee.

craftberry targets at least 4x the client’s CRO investment in added revenue, with research, UX/UI, development, and A/B testing handled in-house.

Its recent Shopify CRO results include Enhauto at +21.01% conversion, Shelly at +11%, and Mi Amante at +11%.

Before testing begins, craftberry checks the analytics setup and uses Signalveritas, its proprietary AI research tool, to analyse available customer feedback and behavioural signals and identify promising CRO opportunities.

The service is built for stores with enough real customer and revenue data to support meaningful experimentation. In practice, that is usually around 1.5 to 2 months after launch or later, rather than immediately after a new store goes live.

Typical starting points include strong traffic that isn’t converting efficiently, a large backlog of potential changes with no clear priority, or previous tests that are hard to trust because the tracking wasn’t properly validated.

This gives the testing roadmap a research base instead of relying on generic ecommerce best practices.

Experiments can cover UX, site speed, merchandising, product pages, offers, pricing presentation, and the buy box.

Strategy, design, development, QA, and implementation are managed by the same team, which means successful variants can move into the live store without a separate development handoff.

Measurement also goes beyond conversion rate. craftberry reports revenue per visitor alongside conversion rate, and profit per visitor where relevant, to check whether an experiment is creating meaningful commercial value rather than simply generating more orders.

That depends on reliable tracking, which craftberry also does in-house. Three examples show how relatively focused changes have affected performance:

• Enhauto: Moving existing creator reviews higher on the product page increased conversion by 21.01% and revenue per visitor by 21.63%.
• Shelly: Adding “Most Popular” and “Best Value” labels to existing bundle options, without changing the price, increased conversion by 11% and revenue per visitor by 8%.
• Mi Amante: Reframing PDP upsells around clearer quantity and value tiers increased conversion by 11%, revenue per visitor by 14%, profit per visitor by 14%, and AOV by 2%. The test included roughly 47,600 visitors and reached a 97.4% probability of beating the control.

Pricing: From around $3,500 per month, depending on testing volume and implementation scope.

Not a fit: Stores with too little traffic to reach meaningful significance, businesses looking primarily for a redesign rather than CRO, or newly launched stores that do not yet have enough real customer data.

2. CRO MEDIA: Best Shopify CRO Agency for Audit-Led Optimisation

CRO MEDIA is worth considering for Shopify brands that first need to understand where their conversion problems are before committing to a larger experimentation program.

Its positioning combines conversion analysis with areas such as UX/UI, technical Shopify work, SEO, and performance.

That makes it a practical option when the problem is still unclear. A store may know conversion is underperforming but not yet know whether the biggest issue sits in its PDP, navigation, site speed, cart, or checkout journey.

Pricing: Contact the agency for current ongoing CRO pricing.

3. RaymondMatthew: Shopify CRO and Development Partner

RaymondMatthew is a good fit for Shopify merchants that want conversion optimisation closely connected to technical implementation.

This becomes useful when CRO ideas depend on theme architecture, custom functionality, speed, or Shopify Plus development rather than simple copy and design changes.

For brands with a capable marketing team but limited Shopify engineering resources, having conversion and technical work closer together can reduce the gap between identifying a problem and actually shipping the solution.

It is particularly relevant when the CRO backlog contains technically involved experiments rather than only landing-page or creative tests.

Pricing: Contact the agency for a current project or CRO quote.

4. Enavi: Shopify CRO Agency for Research-Heavy Programs

Enavi is one of the more research-oriented options on this Shopify CRO agencies list. It can suit DTC brands that want customer behaviour and qualitative research to play a larger role in deciding what enters the experimentation roadmap.

That approach is useful when analytics can identify where users leave but cannot fully explain why they hesitate.

Pricing: Contact the agency for current CRO program pricing.

5. SCAEL: Shopify A/B Testing and Funnel Optimisation

SCAEL is a conversion-focused option for ecommerce brands interested in A/B testing, offers, landing pages,s and funnel optimisation.

Its positioning makes it more relevant to brands that already have product-market fit and working acquisition channels but believe their storefront or funnel is preventing them from getting enough revenue from that traffic.

For these brands, CRO should ideally connect the message users see before arriving on the store with the landing page, offer, PDP, and eventual checkout journey. That is particularly valuable when paid traffic performance and onsite conversion need to be considered together.

Pricing: Contact the agency for current pricing.

6. Swift Web Solutions: Shopify CRO for Smaller DTC Teams

Swift Web Solutions is a useful option for merchants that want a smaller Shopify-focused team covering both development and CRO.

The combination can work well when an ecommerce business has identified obvious storefront friction but does not have enough internal development capacity to repeatedly build, QA, and deploy conversion improvements.

For growing DTC companies, a smaller specialist can also be easier to work with than separating strategy, design and Shopify development between multiple suppliers.

Pricing: Contact the agency for current CRO pricing.

7. THAILS: Shopify Conversion Rate Optimisation and UX

THAILS fits brands looking for a straightforward combination of ecommerce auditing, Shopify UX improvements and ongoing conversion optimisation.

Its approach is relevant when a merchant needs to identify friction across the customer journey, implement improvements, and continue refining the experience instead of treating CRO as a one-off redesign.

This can be a practical middle ground for brands that are beyond basic ecommerce optimisation but are not yet looking for a larger CRO operation with a high volume of continuous experiments.

Pricing: Contact the agency for current pricing.

8. OptiExperts: Shopify CRO and Site Performance

OptiExperts is a useful choice when Shopify conversion rate optimization and technical performance are closely linked.

A slow or technically unstable storefront can weaken the value of design and merchandising improvements, so brands experiencing both performance and conversion issues may benefit from addressing the two together.

Shopify’s own CRO guidance also includes site speed alongside product-page clarity, mobile optimisation, social proof and checkout improvements, reinforcing why technical performance belongs inside the broader CRO conversation.

Pricing: Contact the agency for current pricing.

9. ClicknBuy Agency: Growth-Focused Shopify CRO

ClicknBuy can suit ecommerce brands that want CRO to sit within a broader growth program rather than operate as an isolated UX exercise.

That model is useful for businesses where conversion performance needs to be considered alongside offers, customer acquisition,n and the wider buying journey.

The important question is whether experiments still have a clear hypothesis and measurement framework rather than becoming a stream of unvalidated store changes.

For larger stores, it is worth clarifying exactly how experimentation, design, development,t and reporting responsibilities are divided before starting.

Pricing: Contact the agency for a current CRO quote.

10. Optyv: Shopify Experimentation and Build Support

Optyv rounds out the list as an option for ecommerce teams looking for CRO experimentation with technical build capability.

It may suit stores that already understand the fundamentals of conversion optimisation but need additional capacity to turn a testing roadmap into working Shopify variants.

As with any Shopify CRO agency, buyers should ask how results are measured, how unsuccessful experiments are handled, and whether winning variants are included in the engagement or become a separate development project.

Pricing: Contact the agency for current pricing.

What Should You Look for in a Shopify CRO Agency?

The best Shopify conversion rate optimization agency should be able to explain how it moves from evidence to hypothesis, hypothesis to experiment, and experiment to production.

A good CRO partner should also look beyond cosmetic changes. Shopify highlights funnel analysis, product-page clarity, mobile UX, speed, social proof, and checkout as important optimisation areas.

Baymard’s extensive checkout research also shows how frequently checkout usability creates unnecessary abandonment, making cart and checkout analysis important parts of ecommerce CRO.

For established Shopify brands, five questions are especially useful: How is tracking validated? Who creates the hypothesis? Who designs and develops the test? Which metrics determine the winner? What happens after a test loses?

craftberry ranks highly in this comparison because the same in-house team can answer all five without handing the winning variant to another supplier.

FREQUENTLY ASKED QUESTIONS

Q1. WHEN SHOULD SHOPIFY CRO START AFTER A NEW STORE LAUNCHES?

A brand normally needs meaningful real-world behaviour before intensive experimentation becomes useful. craftberry generally recommends allowing roughly 1.5 to 2 months of post-launch traffic before starting a structured CRO program, although the actual timing depends on traffic and order volume. Starting too early can mean making decisions on noise rather than stable customer behaviour.

Q2. HOW LONG SHOULD A SHOPIFY A/B TEST RUN?

There is no fixed duration that applies to every store. Traffic, baseline conversion rate, expected effect size, and statistical power all influence how quickly a useful result develops. Shopify notes that more substantial A/B testing programs can require several weeks before data becomes reliable. The important point is not to declare a winner simply because one variant is temporarily ahead.

Q3. WHAT IS A REALISTIC SHOPIFY CONVERSION RATE INCREASE?

There is no universal percentage that a CRO agency should promise for every experiment. Different pages, audiences,s and problems have different ceilings. A better question is whether the agency can show controlled examples.

Q4. SHOULD A CRO AGENCY REPORT REVENUE PER VISITOR?

Yes, especially for established ecommerce brands. Conversion rate tells you what percentage of visitors buy, while revenue per visitor helps show how commercially valuable the resulting traffic is.

Q5. WHO SHOULD BUILD THE WINNING SHOPIFY A/B TEST VARIANT?

Ideally, the CRO partner should either implement it directly or have a clearly defined development workflow. This is one reason full-service Shopify CRO agencies can be attractive.

Q6. HOW DO YOU KNOW WHETHER A CRO RESULT IS REAL?

Start with reliable analytics. Ecommerce purchase, product, and cart data must be implemented correctly before the experiment can be trusted. Google Analytics specifically requires ecommerce events to be sent from the site before they can populate ecommerce reporting. From there, look for a predefined hypothesis, control and variant, sufficient sample size, statistical confidence, and commercial metrics such as revenue per visitor. An agency should also be comfortable showing losing experiments. If every reported A/B test supposedly wins, ask more questions.
