Why top DTC brands choose full-business conversion optimization over typical testing

Most agencies test elements. We solve scaling problems. Here's our 3Ps methodology that's generated $100M+ / year in additional revenue for brands scaling from $10M to $100M+

Patterns

Before we touch your site, we need to understand three types of patterns:


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 put brand at the core of our optimization methodology. We help you win.

Questions brands ask before hiring a CRO agency

What does a conversion rate optimization agency do?

A conversion rate optimization (CRO) agency finds out why visitors who could buy don’t, then tests changes that fix it. At SplitBase, every program starts with research: analytics, heatmaps, session recordings and customer surveys. That research becomes a roadmap ranked by revenue impact, and we A/B test what actually drives sales, like offers, purchasing paths and product education. Winning tests get implemented, and every result, win or loss, shapes the next test.

How is SplitBase different from other CRO agencies?

Most CRO agencies test page elements. We start from the business problem, like a best seller that converts poorly or paid traffic that leaves too fast, and test the offers, pathways and messaging that solve it. Your brand stays at the center of every change. It’s why 95% of brands keep working with us after six months.

Who do you work with?

8- and 9-figure DTC ecommerce brands, most of them on Shopify, typically doing $10M or more a year. Clients include Dr. Squatch, L’Oréal, Once Upon a Farm, Amika, Beachbody and Transparent Labs.

How much does a CRO agency cost?

Our CRO programs typically run $8,500 to $15,000 a month, depending on your traffic and how many tests and landing pages you need. Larger programs cost more because they run more tests and build more pages, not because the strategy changes.

How long does it take to see results?

Every CRO client we onboarded in 2023, 2024 and 2025 saw a revenue increase within the first 90 days. On average, brands see a 6 to 10x return on their CRO investment within the first three months.

What testing tools do you use?

We’re official partners of Intelligems, VWO, Convert and Heatmap.com, and a Shopify Plus partner. Depending on the test, we run it on-site with a tool like Intelligems, or inside Meta for landing pages that get paid traffic.

Do you only run A/B tests?

No. Besides full-site testing programs, we design and test landing pages for paid traffic and run conversion-focused website redesigns.
