What this is
CRO is not about increasing traffic.
It is about improving the decision process with the traffic and assets you already have.
Because traffic is never the problem.
Friction is.
How it works
The conversion goal is clearly defined
Behavioral and performance data is collected
Data is analyzed to identify friction points
Hypotheses are formulated based on observed behavior
Variants of the existing page are designed
Technical implementation follows
A/B tests are executed
Results are measured, validated and iterated
The outcome
Clear, data-driven insight into what should be changed, why it should be changed,
and what result that change is expected to produce —
with a clear explanation of why it leads to that outcome.

Conversion Rate Optimization
Improving conversion rates using existing traffic and assets -> lower CAC.
