Don’t just go by case studies or big-name clients. Look at how they approach testing. Do they prioritize data and customer insights, or are they just running button color experiments? Ask about their methodology, their tech stack, and how they handle implementation. It also helps to see if they have experience in your industry or sales model. And check how collaborative they are. The best CRO firms don’t operate in a silo, they work closely with your team across design, dev, and marketing.
