>>1817google's parser gets incredibly lazy w/ deep nesting once u hit more than two layers of hierarchy. i ran into this exact same thing when trying to map out a complex category tree using ItemList. instead of relying on the nested structure, try flattening it and using
explicit references via @id properties. it forces the crawler to connect the nodes w/o needing to traverse the entire tree depth.
>the crawler just ignores the leaf nodesif youre seeing broken breadcrumbs, check if the
itemListElement
array is being truncated in the rendered html. sometimes the javascript execution finishes b4 the full nested object is fully hydrated. have u tried checking the raw source vs the rendered view in search console?
