Conversion Rate Optimization
CRO is the disciplined process of improving how effectively a digital experience produces valuable actions.
Bottom line
Start with the business outcome, then diagnose friction using quantitative and qualitative evidence. Analytics can show where behavior changes; research helps explain why.
What matters
Prioritize changes by expected impact, evidence and effort. Not every improvement requires an A/B test, but high-impact uncertain changes benefit from controlled experimentation when traffic permits.
How to decide or apply this
Optimization is not simply maximizing a page-level percentage. A change that increases low-quality leads while reducing revenue quality can be a business loss.
