Indexability
Whether a page is technically eligible to be crawled, parsed, and included in a search engine's or AI system's index at all.
What it means
A page can be well-written and well-structured and still be invisible to search and AI systems if it's blocked by robots.txt, marked noindex, orphaned with no internal links pointing to it, or returns errors to crawlers. Indexability is the precondition every other optimization depends on, content quality and structured data don't matter for a page that was never allowed to be indexed in the first place.
Why it matters for Shopify
Shopify merchants should audit indexability before investing in content or schema work, fixing a blocked or orphaned page unlocks value from optimization that was already done but never counted.
