If you’re reading this, chances are you’re an entrepreneur trying to scale your Shopify store, a marketing manager looking to impress your boss with higher conversions, or even a CMO of a big brand that sells on Shopify. Either way, welcome, you’re in good company.
Let’s be honest, picking the right CRO agency for your Shopify store can feel like staring at a sushi menu where everything looks good but you only get one pick. Choose right, and your revenue shoots up. Choose wrong, and you’re stuck with mediocre results and an emptier wallet. That’s why we put together this guide. We’ll walk you through 8 CRO agencies that know Shopify inside and out, and help you figure out which one could actually move the needle for your store.
Whether you’re running a small but ambitious Shopify shop or juggling the big guns on Shopify Plus, these agencies have a track record of improving conversions, boosting average order value, and making customers stick around longer. Each one brings its own flavor, some sprint to launch tests in record time, others focus on design or predictive modeling. The fun part is figuring out which approach matches your goals.

How to Pick the Right One
Here’s the truth, there’s no one size fits all CRO partner. The right agency depends on your goals, budget, and tolerance for risk. To make it easier, here’s what we recommend checking:
- Do they have real Shopify experience (especially Plus)?
- Can they show proof of results with numbers and case studies?
- How fast do they launch tests?
- Do they handle everything in house or rely on contractors?
- How do they charge, retainer, performance based, or something else?
- Do they get your brand culture and reporting style?
- Do they help you think beyond the site, like how your CRO work translates into mobile? (Hint: tools like an eCommerce Mobile App make that transition simple.)
If you’re serious, ask them for references from stores similar to yours. Check their case studies. And don’t be shy about grilling them on how they handle test implementation and measurement. After all, they’ll be tinkering with your livelihood.
FAQs
What’s the difference between predictive CRO and basic CRO?
Predictive CRO uses machine learning to forecast winning changes before you test. Basic CRO is more “let’s guess and test.” One’s faster, the other’s slower.
How much should I budget?
Anywhere from about $1,000 a month for flexible services to performance based models that scale with results. Spiralyze’s pay for performance model means less risk for you.
How long before I see results?
Depends on your traffic. High traffic stores can see results in a couple weeks, smaller ones may need a month or two. Spiralyze averages 30–38% lifts in 90 days.
Do I need tech skills to work with an agency?
Nope. Full service agencies cover the nerdy stuff. You’ll just need to share analytics access and business goals.
What should I track?
Start with conversion rate, AOV, revenue per visitor, and customer lifetime value. The pros will set up proper tracking so you’re not guessing.
Can CRO agencies handle custom themes?
Yes. Good ones can work with any Shopify or Shopify Plus theme and hard code changes after tests win.
Should I go retainer or performance based?
Depends on your risk tolerance. Retainers give predictability, performance based models tie the agency’s paycheck to your results. Spiralyze’s model is 100% performance based, so they only win if you do.
