What is conversion rate optimization?
Conversion rate optimization is the practice of improving your website or landing pages so a higher percentage of visitors complete a goal. Instead of driving more traffic to a page that converts at two percent, CRO focuses on turning that two percent into four -- effectively doubling your results without increasing your ad spend.
CRO is grounded in data, not guesswork. It combines quantitative analysis (analytics, funnel data, conversion metrics) with qualitative research (user surveys, session recordings, heatmaps) to form hypotheses about what is preventing visitors from converting, then tests those hypotheses through controlled experiments.
The discipline matters because small improvements in conversion rate compound dramatically. A half-percent increase on a high-traffic page can mean thousands of additional leads or hundreds of thousands in additional revenue over a year -- all from the traffic you are already paying for.
