CRO & Experimentation
Conversion rate optimization and experimentation tools show how visitors actually behave on a site through heatmaps and session recordings, then let teams test changes with A/B and multivariate experiments before committing to them.
Traffic is the expensive part of a funnel and conversion is the free part, which is why a category exists purely to raise the second number. It splits into two halves that increasingly ship together: behavioral analytics, meaning heatmaps, scroll maps, and session replays that answer why a page fails, and experimentation, meaning split tests that prove whether a fix worked. For a small business the practical constraints are traffic volume, since low-traffic sites cannot reach significance quickly, and page speed, since client-side testing scripts are a real performance cost.
