What is a CRO designer, and when should you hire one?
George Peric · Conversion designer · 3 min readShort answer
A CRO (conversion rate optimization) designer designs the pages and flows that turn visitors into customers, such as ads, landing pages, forms and checkouts, and proves each change with A/B tests. Unlike a general web designer, a CRO designer is judged on revenue per visitor, not on how the page looks.
Key takeaways
- A CRO designer combines UX/UI design with research and experimentation.
- The output is a measured change in conversions or revenue, not just a design file.
- Hire one when you already buy traffic and your pages, forms or checkout are the bottleneck.
- Look for real test results reported in money, not only portfolios of pretty pages.
What does a CRO designer do?
A CRO designer finds where visitors drop off, designs a better version, and runs an A/B test to prove it. The work usually covers:
- Research: analytics, funnel drop-off, customer reviews, surveys and session recordings.
- Hypotheses: a clear reason why a change should work, written before the design.
- Design: ads, landing pages, quiz funnels, lead forms, product pages and checkouts.
- Copy: headlines and calls to action, because words often move conversion more than layout.
- Testing and analysis: setting up A/B tests and reporting the result in revenue.
How is a CRO designer different from a UX or web designer?
| Web / UI designer | UX designer | CRO designer | |
|---|---|---|---|
| Main goal | A good-looking, on-brand site | A usable product | More revenue per visitor |
| Typical work | Websites, brand pages | Product flows, research | Ads, landing pages, funnels, checkouts |
| How success is measured | Feedback, brand fit | Usability, task success | A/B test results in money |
| Works closely with | Brand, developers | Product, engineering | Performance marketing, analytics |
The roles overlap, and good CRO designers have strong UX and UI skills. The difference is the finish line: a CRO designer’s work is not done when the design is approved, it is done when the test result is in.
When should you hire a CRO designer?
When you already have traffic and the pages are the bottleneck. Typical signs:
- You spend on paid ads and your landing pages convert below what the ads deserve.
- Lots of people start a form, quiz or checkout, and few finish it.
- Your team has ideas but no one who can design, ship and measure them quickly.
- You run A/B tests but they rarely win, or nobody can say what a win was worth.
If you have very little traffic, start with research-driven redesigns and before/after measurement. A/B testing needs enough conversions to give a reliable answer.
What should you look for when hiring one?
- Results reported in money. A lift in revenue per visitor, translated into yearly revenue, tells you more than a screenshot.
- A clear reason behind each change. Ask why a design should work before you look at how it looks.
- Honest reporting. Good CRO people talk about losing tests and guardrail metrics, not only wins.
- Range across the funnel. Ads, landing pages and the flows after them work best when one person thinks about them together.

FAQ
What does CRO stand for?
Conversion rate optimization: the practice of increasing the share of visitors who take a desired action, such as buying, booking or submitting a form, usually through research, design changes and A/B testing.
Is a CRO designer the same as a conversion designer?
Yes. “Conversion designer” and “CRO designer” describe the same role: designing pages and flows to increase conversions and proving the changes with tests.
Can a CRO designer also build the pages?
Many can. Some hand off designs to developers; others, like me, can also build and launch landing pages so tests start sooner.
How much traffic do you need for CRO?
A/B testing needs enough conversions per variant to reach a reliable result. With lower traffic, CRO still works through research-driven changes measured before and after, but the results are less precise.
