The BreadcrumbList rollout playbook for large templated sites

Breadcrumb markup is the most under-shipped easy win in the spec, and as of this week it's still one of the few rich results Google draws for nearly everyone. The trap is doing it inconsistently across templates. Sequence it like this:

— Map every URL depth to a single source-of-truth path generator
— Set position as a strict integer sequence starting at 1, no gaps
— Use absolute URLs in each item, never relative paths
— Drop the final breadcrumb's item if it's the current page — last crumb can be name-only
— Validate one URL per template, not one per page — templates fail uniformly
— Confirm the visible breadcrumb matches the markup order exactly

What it means for you: mismatched visible-vs-markup order is the top breadcrumb rejection. Watch this — breadcrumbs feed AI engines' sense of site hierarchy, so the upside now runs past blue links.
