什么是转化？

A conversion is any action you define as valuable to your business. This could be a purchase, a lead form submission, a download, a sign-up, or even a specific page view. The key is that it's a measurable step a user takes that aligns with your business goals. Revenue is a result of conversions, but not a conversion itself. "Successful ad" is too vague; an ad is successful if it drives conversions. "Another word for a click" is incorrect; a click is an interaction, but a conversion is a specific, desired outcome that often happens after a click.
