What is conversion rate optimisation?

Not a set of tricks for making buttons bigger. A method for finding where intent is being lost, and fixing the reason rather than the symptom.

The short answer

What is conversion rate optimisation?

Conversion rate optimisation is the practice of increasing the share of visitors who complete a meaningful action, by studying where and why they stop. It is research first and testing second: the test is how you confirm an explanation, not how you find one.

In short

Key takeaways.

  • It starts with a question, not a hypothesis A hypothesis you cannot trace to an observation is a guess with better grammar.
  • Traffic quality bounds the ceiling The wrong visitors convert badly no matter how good the page is.
  • Small samples lie confidently Most reported wins are noise, read early.

The short version

Find where people leave. Work out why. Change that specific thing. Confirm the change did what you expected. Repeat.

Why it is usually done badly

Because the testing tool is easier to buy than the research is to do, teams start with variants instead of questions. The result is a long list of inconclusive tests and a working theory nobody can state.
