What is crawlability?
SEO Definition and Examples
Crawlability is the ability of Google's robots to access, navigate and read your site's pages — an essential prerequisite for indexing and ranking.
Full Definition: What is crawlability
Crawlability describes how easily Googlebot — Google's indexing robot — can access and navigate your site. Factors that affect it: a restrictive robots.txt, missing or broken internal links, redirect chains, server errors (5xx), complex pagination structures, excessive JavaScript that hides content, and an exhausted crawl budget (on very large sites). Crawlability is the first condition for indexing — what cannot be crawled cannot be indexed, and what is not indexed cannot rank.
Why Does Crawlability Matter for SEO?
Googlebot has a limited crawl budget per site. If you waste crawl time on worthless pages (duplicate filter pages, parameter URLs), Google does not reach the important pages. Large sites can lose tens of thousands of pages from the index due to crawlability issues.
