Which metric shows the average number of pages viewed per session?

Answer: Pages per session

Pages per session is a key metric that indicates the average number of pages a user views during a single visit to a website.

This metric helps assess how effectively a website guides users through its content and provides value.

What can server log file analysis capture that JavaScript page tagging commonly misses?

What is 'multivariate testing' (MVT) in CRO?

Answer: Testing multiple changes across multiple page elements at the same time

Multivariate testing simultaneously tests multiple variations of multiple page elements to identify which combination produces the best results.

Which best describes a good report annotation practice for stakeholders?
