The Growth Rock Ecommerce CRO Agency

Our boutique ecommerce CRO agency is 100% focused on conversion rate optimization and AB testing for ecommerce websites. We are not part of a larger “digital marketing” agency where conversion rate optimization (CRO) is one of many services, nor is ecommerce one of many different verticals we service.

We’ve been running AB tests to increase conversions and online sales for 6 years. We’ve run them on Optimizely, VWO, Google Optimize, and Adobe Target.

We only do CRO, we only do it for ecommerce websites, and we only work with 4 – 6 clients at a time. This is why we’ve been able to  and conduct large ecommerce UX research projects that help ecommerce companies worldwide (beyond just our clients).

How Our CRO Process Works

Our conversion optimization process follows a 4 step process. Here is exactly how we execute each step for your company.

  1. Customer Experience Research and Ideation – We base our AB tests on a deep understanding of your website visitors, the customer experience they report receiving, and what analytics data tells us (Google Analytics and Adobe Analytics). We implement user research techniques such as: live user testing sessions, analysis of reviews and testimonials, session recordings, and polls. We then create a spreadsheet of hypothesis of UX changes that could improve conversion rate.
  2. AB Test Design – We take the top ideas and design variations to the site that will test those hypotheses (e.g. changes to product pages, listing pages, cart, checkout, homepage, mobile, desktop, and more). We get consensus with your team then move to development.
  3. AB Test Development – Our own developers, well versed in AB test development of ecommerce sites, code the variations in the AB testing platform (we don’t need to touch your server side code). We do this in days, not weeks or months.
  4. AB Test Results Interpretation – We check and report on results weekly. We are also thorough in analyzing the statistical significance of tests so you don’t falsely declare winners.
  5. Implementation (Shopify Only) – For Shopify clients, we also have a Shopify development team that can implement winning variations permanently on your site as well make other non-AB test site changes. Reach out to us below to learn more

ROI and Pricing

An ongoing CRO program like the one we provide is best for ecommerce sites with at least 3,000 or more monthly transactions and 7 figured in annual revenue. For these million dollar and larger ecommerce brands, here is why we think you’ll benefit from choosing to have us be your conversion rate optimization agency:

  1. Less Expensive: Our monthly rates are far less expensive than building an in house team (by a lot).
  2. More Experience: We run hundreds of AB tests, exclusively on ecommerce sites every year. We only work on ecommerce, and only do CRO. We have an internal database of patterns we’ve detected on different ecommerce sites over the years so we have a great sense of what works and what doesn’t.
  3. Faster Ramp Up: We hit the ground running with our set process from day one. We’ve executed this process multiple times, no “on the job” learning required.
  4. More Flexibility: We don’t require a 6 or 12 month contract.

Our CRO service ranges from $4,000 –  $7,000 per month.

Frequently Asked Questions

Does your agency have experience with our ecommerce platform (Shopify Plus, Magento, BigCommerce, Woocommerce, Salesforce Commerce Cloud, etc.)?

Chances are we do. We’ve worked with many ecommerce platforms, and in particular have lots of experience with Shopify Plus and Magento. But the larger concept is that, for our optimization service, it doesn’t matter which platform you are on. We use ab testing software which tests changes on the front end of your ecommerce site regardless of your backend software. When we have a winning variation we hand it over to your development team to implement through your backend.

For Shopify Plus in particular, we have developers that can directly implement winning changes in your backend.

Can you run AB tests in Optimizely, VWO, Google Optimize, or Adobe Target?

Yes! We are platform agnostic. We have run AB tests on all of the above platforms, are Optimizely developer certified, have a close relationship with VWO (and have published a case study on their blog), and have run many tests on both Google Optimize and Adobe Target. We’re happy to also advise on the pros and cons of each platform and help you make the best decision for your company.
