Why are server and AI-bot logs important?

Because they show what actually reached the site, and analytics does not.

Analytics tells you about humans who loaded a page with JavaScript enabled. It cannot tell you whether an AI crawler ever arrived, what it read, or how often. As more discovery happens through AI systems, that blind spot gets more expensive.

Worth being precise: crawler behaviour is observable. What an AI system does with what it read is not. We report the first and do not pretend to the second.
