Crawlability matters because it is the first gate in getting found. A page blocked in robots.txt, hidden behind a broken link, or returning server errors will never be read, so it can never be indexed or cited. Strong internal linking and clean server responses keep the path open for crawlers.
Crawlability is closely tied to indexability: a page must be crawlable before it can be indexed. Together they determine whether your content is even in the running. Learn more in the llms.txt guide. Back to the SEO & AEO glossary.
FAQ
How is crawlability different from indexability?
Crawlability is whether a bot can access and read a page; indexability is whether that page is eligible to be stored in the index. A page can be crawlable but not indexable, for example if it carries a noindex tag. Crawling always comes first.
What commonly blocks crawlability?
The usual culprits are disallow rules in robots.txt, server errors or slow responses, pages with no internal links pointing to them, and login walls or scripts that bots cannot execute. Auditing these access barriers is one of the fastest ways to recover lost visibility.
