Crawlability
Crawlability is whether automated crawlers, including AI answer-engine bots, can reach and fetch your pages at all. If a bot is blocked by robots.txt, a login wall or a slow server, your content can't be read, let alone cited.
It's the first prerequisite for AI visibility: you can't be the answer to content a bot never fetched. Related: does ChatGPT read JavaScript?
How do I make my site crawlable by AI?
Allow the relevant bots in robots.txt, avoid login walls on public content, keep responses fast, provide a sitemap, and serve your content in raw HTML rather than only via JavaScript.
