More traffic won’t fix a store
that leaks revenue.

You test hundreds of ad creatives every month, but what if your website was actually what’s holding you back?

We find where your store loses buyers, then we fix it. On your homepage, product pages, collection pages, offers, cart and checkout, we’ll apply fixes and run A/B tests that will help you hit your growth goals.

Your store is the lever.
Nobody owns pulling it.

Media buyers stop at the click, developers aren’t marketers and your marketers are too busy running marketing. So your store gets a redesign every few years and a few tweaks in between.

No one on the team owns CRO

A/B testing is a side task for marketing, design or development. It happens when there’s time, but there’s never time.

In-house tests never find a winner

Tests run for weeks, results come back flat. Launching tests is one thing, but having the right strategy is another.

The redesign looked great. Conversion didn’t move.

You launched a new site that looks better, but performance dropped and you don’t know what to do.

The last agency sent best practices

Lots of agencies end up launching generic ideas any AI tool could come up with. If there’s no real strategy, you’re playing the lottery.

Why Shopify brands work with SplitBase

01

We own the program

Research, roadmap, design, copy, development, QA and analysis. You get a proactive expert partner who gets it all done, not one that waits for your ideas.

02

Accelerate new customer acquisition

Growth stalls when customer acquisition slows down. We combine personalization with A/B testing and landing pages to keep you growing.

03

Judged on revenue, profit and LTV

Every test is measured on what matters: profit and revenue lift, and test-specific metrics such as LTV, conversion rate and AOV.

How we decide what to test on your Shopify store

Most agencies test elements; we solve scaling problems. Every test on your store comes out of our 3Ps Method: Patterns, Perception and Proof.

Patterns

Before we touch your site, we need to understand three types of patterns that reveal why people buy, and why they don’t:

Behavioral patterns show us how visitors behave.

Voice patterns reveal what’s happening in customers’ minds.

Resistance patterns uncover the friction points blocking purchases.

Perception

The most overlooked conversion factor? Brand perception.

Does your narrative resonate with customers? How are you positioned against competitors? How are you perceived?

Sometimes your site works perfectly, but you lose customers because competitors look stronger.

We’re the only CRO agency that puts brand at the core of its optimization methodology. We help you win.

Proof

We A/B test the business elements that drive outcomes:

Offers (subscriptions, upsells, bundles) to optimize AOV and LTV.

Pathways (product discovery, customer journey, landing pages) to guide buyers.

Experiences (copy, visuals, layout) that convert your audience.

Sharper tests

Every hypothesis gets refined by customer insights

Smarter prioritization

Thousands of data points allow for more accurate prioritization of tests and help predict potential impact.

No missed opportunities

Behavioral, quantitative and qualitative patterns feed directly into your roadmap.

Brand-aligned CRO

Wins that still look
like your brand.

A winning test shouldn’t make your store look like a template, and it shouldn’t win by ruining your aesthetics.

Every variant and landing page is designed in alignment with your brand, written in your voice and built in Shopify.

“They worked really well with our internal brand marketing teams to make sure we were creating a landing page based on our brand and performance marketing principles.”

We’ve identified what stops people from converting, and where your website leaks money. Wins, losses and insights from every test shape the next round of tests.

Will CRO lower our CAC?

+

Usually, yes. On the same ad spend, more visitors become customers, so each one costs less: a 20% conversion lift cuts CAC by about 17%. For paid landing pages we also test at the ad level in Meta, so you see the effect in your ad account, not just on your site.

How do you connect tests to ROAS, CAC and MER?

+

Every on-site test is judged on metrics that matter and drive revenue, such as revenue per visitor, conversion rate, AOV, add-to-cart rate, subscription take rate, and LTV. We also measure the revenue and profit uplift generated by every test. Landing pages for paid traffic are also compared inside Meta, where CAC and ROAS are measured. Every test report shows the impact on your KPIs.

We’re a subscription brand. Do you optimize for first orders or LTV?

+

It depends on whether your goal is immediate cash flow and subscriber count, or LTV. We’ll optimize for what aligns with your business goals and makes the most financial sense. We test purchase options, incentives, frequency framing, pricing and upsells. In each case, we look at both the immediate performance impact and the cohort-based impact over time, including churn, payback period and LTV. For example, a test that lifts first orders but brings in subscribers who churn isn’t a win.

How much does a Shopify CRO program cost?

+

Programs start at $8,500 a month. Pricing depends on your scope and order volume: the more orders you get and the more landing pages you have, the more tests we can run. We only take on brands where the program can realistically pay for itself, and on average clients see a 6–10x ROI within their first three months.

What’s the minimum commitment?

+

Programs start with a minimum commitment so tests have time to run, reach a reliable result and compound. We share the exact term in your proposal. About 95% of clients keep working with us after it ends.

How many tests do you run a month?

+

It depends on your traffic and order volume. The more orders you get and the more landing pages and funnels you have, the more tests we can launch. We plan the pace in your roadmap and tell you what to expect for your store before we start.

How much traffic does my store need?

+

We work with stores doing at least 3,000 orders a month. Below that, tests take too long to reach a reliable result.

How long until we see results?

+

Your first tests usually go live by week two. Within 30 to 60 days you’ll have clear learnings and early wins, and on average brands see a 6–10x ROI by month three.

How do you report results, and how often do we talk?

+

Every test gets a report with the results, key metrics and what we learned, whether it wins or loses. We meet weekly or bi-weekly to review results and plan next steps, and we’re on Slack for questions in between.

Do you use your own designers?

+

Yes. Our designers are in-house and work inside your brand guidelines and design system. If you have in-house designers, we work alongside them or from their files.

Do you replace our Shopify development agency?

+

No. Your developers keep owning theme builds, features and migrations. We design and build test variants ourselves, in your theme and testing tool, so tests never wait in your dev queue. For CRO clients who need extra development help outside our CRO scope, we can help at a fixed hourly rate.

We’re mid-redesign or replatforming. Should we wait?

+

No need to wait. We often work with brands during a redesign or replatform: we use research and data to guide design decisions, test parts of the new design before launch when we can, and help you avoid a drop in performance.

How do you plan around promos, launches and BFCM?

+

We build the roadmap around your promo calendar. Landing page and offer tests can run through promos, while tests on checkout and other core flows pause when traffic gets unusual. Before BFCM, we test offers early so you go into November knowing what works.

How do you test landing pages?

+

Two ways. For smaller changes, we run traditional A/B tests within your A/B testing tool, such as Intelligems. For net-new pages or pages targeting new angles, we recommend testing them directly in Meta. While we won’t create the new ads for you, our team will work alongside your team or media buyer to make sure the tests are set up for success.

Can you test prices, offers and free-shipping thresholds?

+

Yes. We regularly test pricing presentation, bundles, offers and free-shipping thresholds when your traffic allows a reliable result. We plan these tests carefully to avoid unintended effects on customers or operations.

Can you work on our Shopify checkout and apps?

+

Yes. We test and build on Shopify checkout, and we install and configure the apps your tests need, from page builders like Replo to subscription apps like Recharge or post-purchase apps like Aftersell by Rokt.

Do we own the pages and code you build?

+

Yes. Landing pages are built as editable sections in your theme or in Replo, so your team can change them without us. Pages, tests, code and research stay yours after the program ends.

Will A/B testing slow my store down?

+

We build tests to keep your store fast. Variants are built in your theme or in Shopify testing tools like Intelligems, and every launch goes through QA across devices before it goes live.

Do I need Shopify Plus to work with you?

+

No. We work with brands on Shopify and Shopify Plus. Some checkout tests need Plus, but everything else works on both.

Do you guarantee results or offer performance-based pricing?

+

No. Conversion rates move with many things outside testing, such as traffic quality, promotions, stock levels and product mix, so no one can tie a specific dollar result to a single change. Instead, we only take on brands where our numbers show the program can realistically pay for itself.
