The 50 best Shopify CRO agencies: Scored & priced (2026)

Why Shopify CRO engagements can underdeliver

CRO programs often report "tests shipped" or "win rate" as the headline metric. The issue with this is that both can be gamed. A shop that ships 10 small, safe tests a month looks busier than one that completes only two tests targeting the checkout flow.

The other common pitfall is treating conversion rate as the finish line. A homepage redesign that raises conversion rate by 8% while average order value drops by 12% isn't a win. Instead, the right unit to optimize for is revenue per session (or per visitor), not conversion rate in isolation.

Platform depth also matters more than most brands assume. Shopify's checkout is locked down for most merchants (Shopify Plus opens more of it), theme architecture varies enormously between Online Store 2.0 builds and legacy themes, and app conflicts are common. As such, an agency's Shopify Plus Partner status and app-stack literacy should be read as proof of practical experience.

How we evaluated these Shopify CRO agencies

No agency paid to appear or influence its position. We ranked every agency on five weighted criteria, using the same framework we apply across every agency ranking on this site.

Olifant's own figures come from our client data; every other agency's details come from its own public claims, Clutch/G2 listings, and available online data collected during September 2026. Agencies #1-17 receive the full scored ranking below; agencies #18-50 appear afterward in a lean directory by category strength, since public data was thinner for that group.

Agencies 18-50 appear in the lean directory below the full profiles, since public data on team structure, pricing, and named results was thinner for these agencies at the time of research.

17 of the best Shopify CRO agencies in 2026 (full profiles)

#1 craftberry: Best for boutique Shopify Plus CRO

Founded: 2015 HQ and offices: Europe; working with brands in Europe and the US Team size: ± 11-50 Starting price: $3,500 Pricing model: One-off audit + monthly retainer; development billed separately Shopify Plus Partner: Shopify Premium Partner Guarantee/contract terms: Targets 4x the CRO investment in added revenue; if not reached, work continues at no extra cost

craftberry   owns the full cycle in-house, from idea and design to development. craftberry is a boutique Shopify Plus agency reporting more than 800 launched projects. What separates it from generalist CRO-only agencies is its in-house development bench. 

When working with craftberry, CRO recommendations can be implemented as custom-engineered fixes rather than handed off to a separate dev team. The fact that implementation doesn’t need to be handed off to another vendor means that most of its projects become long-term engagements. When working with craftberry, opportunities are prioritized with Signalveritas, its proprietary AI tool that turns customer behavior data into ranked, evidence-backed test hypotheses. The same in-house team then designs, builds, and tests the changes rather than handing them off to a separate dev team. The fact that implementation doesn’t need to be handed off to another vendor means that most of its projects become long-term engagements.

Pros:

• Outcome-based guarantee
• Full CRO cycle in-house: idea, design, development
• Proprietary AI tool (Signalveritas) to prioritize quick wins
• Deep Shopify Plus project volume (800+ launches)
• Closer senior attention

Cons:

• Requires sufficient traffic and order volume - not ideal for early-stage stores.

Main services:

• Shopify CRO
• A/B testing
• Audits and analysis
• Landing Page Optimization
• Shopify design and development

Proven results: 

• Enhance Auto: 21.01% conversion rate increase and 21.63% revenue per visitor uplift
• Mi Amante: 11.1% conversion uplift and 13.8% revenue increase per visitor
• Shelly: 11% conversion rate increase and 8% revenue per visitor uplift

Not for: Stores with low traffic and brands not on Shopify

Why it ranks here: Score of 88/100 (Results: 26/30, capped by conversion-rate-only public case studies; Senior depth: 22/25; Shopify depth: 19/20; Fees: 13/15; Track record: 8/10)

#2 Olifant Digital: Best for CRO run by one senior team, not a siloed vendor

Founded: 2018 HQ and offices: New York City, with locations in several more cities globally Team size: ± 11-50 Starting price: $2,000 per month Pricing model: Flat retainer Shopify Plus Partner: Not disclosed Guarantee/contract terms: 60-day money-back guarantee

We treat CRO as one input into a connected Amazon and DTC growth system, instead of a standalone audit as is often the approach. The same senior team that runs your Meta and Google ad accounts also owns your CRO roadmap. This means that creative that wins in paid media gets tested on-site next, and vice versa, avoiding the common pitfall where a CRO vendor optimizes a page in isolation.

Every account is staffed by specialists with a minimum of seven years' experience, while our in-house AI platform, Olifant AI, flags underperforming pages and checkout drop-off points daily rather than per a monthly reporting cycle.

Pros:

• CRO run by the same senior team as paid media and retention, not a siloed vendor
• Transparent pricing with a 60-day money-back guarantee
• Daily monitoring rather than a monthly test cadence

Cons:

• Not a Shopify Plus-exclusive specialist (better fit for brands that want CRO bundled with Amazon/DTC growth)
• Onboards only two to four new clients per month

Main services:

• CRO
• Amazon PPC and account management
• Meta/Google/TikTok ad buying
• Email and SMS retention

Proven results:

• FreshTrends: Scaled DTC revenue by 211% in 60 days (CRO + paid media combined)
• Wildride: Added $179,009 per month in DTC revenue in 42 days

Not for: Brands that want a pure-play, testing-only CRO vendor with no media or retention involvement

Why we rank here: Score of 84/100 (Results: 26/30; Senior depth: 22/25; Shopify depth: 13/20; Fees: 14/15; Track record: 9/10)

#3 Blend Commerce: Best for Shopify-only CRO tied to AOV and retention

Blend Commerce runs CRO mainly for Shopify stores using its proprietary "Buy Trifecta Framework". This targets conversion rate, average order value (AOV), and retention simultaneously rather than conversion rate alone.

Unlike many CRO agencies that focus solely on testing or recommendations, the Blend team is available across all stages, from diagnosis to implementation. That said, if your brand doesn’t run on Shopify it will only offer actionable insights to be implemented by your own team.

SplitBase works almost exclusively with high-growth 8- and 9-figure DTC brands where a heavy-handed CRO playbook (e.g., urgency banners and aggressive pop-ups) would damage the brand. Its methodology starts with deep customer research that includes qualitative interviews, session recordings, and behavioral analytics before any test hypothesis is written. 

Then, when it’s time for testing, it most often tests messaging, hierarchy, social proof, pricing, and bundles across product and landing pages as well as checkout flows. 

Pros:

• Published, named client results

Cons:

• Pricing and minimum engagement not disclosed

CRO is only the entry point. In addition to CRO, it also offers paid media programs to DTC brands helping them to capture the gains of the improvements that were made to speed and design.

KlientBoost treats landing page design, A/B testing, and paid media as one connected system rather than separate services. This is useful when a "CRO problem" is actually a traffic-mapping problem (an ad sending four different search intents to one landing page, for example).

NoGood treats CRO as one lever inside a broader growth-marketing engagement that includes paid media, SEO, and lifecycle rather than a standalone service.

Lean directory: The rest of the top 50 Shopify CRO agencies

These 33 agencies show up consistently across Clutch, Google, and independent CRO/Shopify agency directories, but public data on team structure, exact pricing, and named client results was thinner at the time of research. As such, they're ranked here by category strength rather than the full five-criteria score used above.

How to spot an expert Shopify CRO agency

Verifiable results

An expert CRO agency can point to specific results tied to real client accounts. Ideally, these results should be reported as revenue-per-session or AOV impact, not conversion rate alone.

The question to ask the agency: "Can you show me a named client result with the exact metric, lift, and timeframe. Also, what happened to AOV in the same period?"

Research before testing

Strong agencies run a research phase (e.g., session recordings, customer interviews, and/or funnel analytics) before writing test hypotheses.

The question to ask the agency: "Walk me through your research process before you propose a single test."

Shopify-specific technical depth

Generalist CRO agencies apply the same playbook regardless of platform. Shopify has real constraints like checkout customization limits (except on Plus), theme architecture, and app conflicts that a specialist should be able to understand and address easily.

The question to ask the agency: "How does Shopify's checkout affect what you can and can't test, and how do you handle app conflicts during a test?"

Fee transparency

An agency should be upfront about its pricing model and minimum engagement length.

The question to ask the agency: "What's your starting price and can I work on a per project basis?"

Risk and track record

Guarantees are rare in CRO (ConversionTeam is a notable exception with a published 30% improvement guarantee). That said, agencies should still be transparent about typical timelines and win rates

The question to ask the agency: "What's your test win rate, and what happens if we don't see results after 90 days?"

Which Shopify CRO agency fits your stage

Under $2M annual online revenue

Traffic volume is usually the limiting factor as most CRO agencies need meaningful monthly sessions to reach statistical significance. Brands that are still generating less than $2M in annual online revenue can consider Olifant Digital’s CRO bundled with paid media/retention under one flat retainer with a 60-day guarantee.

$2M-$20M

This is the sweet spot for Shopify Plus specialists like SplitBase, Blend Commerce, craftberry, Convertibles, and Trellis, plus generalist e-commerce CRO agencies like The Good and KlientBoost.

Enterprise ($20M+)

Agencies built for this scale include Invesp, Speero, and ConversionTeam. All these agencies have enterprise client rosters and larger published testing volumes.

What a Shopify CRO agency costs in 2026

The final verdict

craftberry ranks first on this list thanks to a risk-sharing model: the agency sets a goal of returning 4x the client's spend in added revenue and continues at its own cost if it falls short. Strategy, UX design, development and A/B testing all stay with one team, and Signal Veritas, the AI research tool craftberry built, identifies which changes are most likely to pay off first.

Olifant Digital ranks second, and it's the strongest fit if you want CRO run by the same senior team that owns your Amazon PPC, paid social, and retention. We publish our pricing (starting at $2,000 per month) and offer a 60-day money-back guarantee, which most specialist CRO agencies don't.

If you're a $2M+ Shopify Plus brand that wants a pure-play testing specialist with published case studies, SplitBase and Blend Commerce are also strong picks.

Frequently asked questions

What is the best Shopify CRO agency in 2026?

There's no single objective best Shopify CRO agency, because the right pick depends on your revenue stage and needs. craftberry is our top-ranked pick for Shopify Plus brands that want CRO, design and development under one roof, prioritized by its own AI tool, Signal Veritas, and backed by a promise to keep working at no extra cost until it delivers 4x the client's spend in added revenue. Olifant Digital is the top pick if you want CRO bundled with paid media and retention, and SplitBase, Blend Commerce, and Invesp are strong choices for standalone, pure-play testing engagements.

How much does a Shopify CRO agency cost?

CRO audits typically cost between $1,000 and $5,000. Ongoing retainers range from roughly $2,000 to $10,000 per month depending on traffic volume and scope, while enterprise engagements with agencies like Conversion or Speero can run well beyond that.

How is CRO different from Amazon PPC or paid media?

CRO improves how efficiently your existing traffic converts; PPC and paid media get you more traffic. CRO can be run separately from paid media and several CRO agencies do exactly that. However, bundling both under one team (as Olifant Digital does) avoids the common pitfall where a media agency drives traffic to a page that a separate CRO vendor hasn't optimized for that specific audience. 

What minimum traffic do I need before hiring a Shopify CRO agency?

Most CRO agencies need at least 20,000 to 30,000 monthly sessions to reach statistical significance on tests within a reasonable timeframe. If your sessions fall below that, rather invest in traffic first, or focus on qualitative research and UX fixes than formal A/B testing.

Which Shopify CRO agencies are Shopify Plus Partners?

Confirmed Shopify Plus Partners in this list include SplitBase, Blend Commerce, craftberry, Convertibles, and Trellis. That said, several other agencies work with Shopify Plus stores without being formally certified partners.

Which Shopify CRO agencies offer a guarantee?

Olifant Digital offers a 60-day money-back guarantee on its overall engagement (which includes CRO). ConversionTeam also offers a guarantee, but instead of returning the management fee it will work for free for up to three months if it fails to improve your conversion by 30%. 

How long before I see results from a new Shopify CRO agency?

Quick UX fixes can show impact within two to four weeks. However, the first ROI-positive testing phase typically emerges only around the 90-day mark, with other gains building over six to twelve months as the testing program matures.

Should I choose a Shopify-only CRO specialist or a platform-agnostic one?

If your store is Shopify Plus with real checkout customization needs, a Shopify-specific specialist like SplitBase, Blend Commerce, craftberry, or Trellis will generally understand platform constraints faster. Platform-agnostic firms (e.g, Invesp, Speero, or Conversion) bring more testing volume and enterprise experience, but may need ramp-up time on Shopify-specific quirks.

What's the difference between a Shopify agency and Shopify CRO agency?

A general Shopify agency builds and maintains your store. A CRO-focused agency specifically runs structured tests on on-page changes, checkout flows, and messaging. These tests are validated with real traffic and statistical significance, rather than shipping redesigns based on opinion.

How long does a real CRO test need to run?

CRO tests need to run long enough to reach statistical significance on your traffic volume, which varies by store size. For example, a high-traffic store might validate a test in two weeks, while a lower-traffic store may need six to eight weeks. Any agency promising a definitive winner in 48 hours isn’t running a statistically sound test.

What should I ask on the discovery call?

Ask to see an example of a named case study that includes the specific percentage lift and what was actually tested. Also, ask how they determine statistical significance, and whether recommendations get implemented by their own team or handed off to yours. The agencies that answer with specifics are the ones running real programs. The ones that pivot to a portfolio of before-and-after screenshots typically can't back the number.
