Does it help AI visibility?
Evidence is limited. Treat it as a low-effort extra rather than a strategy. The things that clearly matter are crawlable pages, consistent facts, strong content and third-party mentions.
Don’t block AI crawlers by accident
Check robots.txt and your CDN or firewall rules. Some security settings block AI crawlers such as GPTBot or PerplexityBot, which can stop your content being used in answers.
