Crawlability is how easily search engines can discover and access a website’s pages and resources.
It matters because organic search compounds over time when pages are technically accessible, useful, differentiated, and connected to real search intent. Clear SEO terminology also helps teams avoid shortcuts that create long-term risk.
Example
An important article linked from a normal HTML navigation path is easier to discover than one accessible only through an unsupported interaction. Crawl the site and inspect blocked resources to identify obstacles to discovery and retrieval.
