Most CRO programs run on vibes. Someone notices the hero copy is "weak," changes the headline, declares victory when conversions go up 4% the next week, and calls it CRO. That's gambling with extra steps.
Real CRO starts with research, not tests.
Quantitative. Pull 90 days of GA4 data. Where do people drop off in the funnel? Which pages have abnormally high bounce rates? What's the time-on-page on key conversion pages? You're looking for the biggest gaps between what should be happening and what is.
Qualitative. Watch 30 session recordings of users who didn't convert. Look at heatmaps for click rage, dead clicks, and scroll depth. Read every word of the last 50 form submissions. The patterns jump out fast.
Customer interviews. Call 10 recent customers. Ask: "What almost made you not buy?" and "What did you Google before you found us?" The answers will rewrite half your homepage.
Then you test. Most teams skip the research and go straight to testing. They burn 3 months running tests with no clear hypothesis and call it a "learning agenda." We've audited dozens of these programs. They never compound.
The CRO programs that compound run 4-6 tests per quarter on hypotheses grounded in actual research. Each test has a documented hypothesis, expected impact, kill criteria, and measurable result. Wins ship. Losses get cataloged. The team gets smarter every quarter.
The difference between gambling and engineering is research. CRO is engineering or it's nothing.
