Thin taxonomy pages need stricter index-or-not decisions.

Taxonomy pages can help users, but only stronger ones should be pushed as indexable destinations.

What changed
Taxonomy pages are being judged more strictly on standalone value
Editorialized topic hubs perform better than empty archives
Selective indexing is often healthier than blanket indexing
Who it affects
Directory sites
Publishers
Blog-heavy sites
Anyone using tags and archives aggressively
What to do now
Review taxonomy pages by content count and usefulness
Noindex or omit weak archives from the sitemap
Improve stronger hubs with unique intros and related-topic guidance
Focus indexing effort on pages with real demand and breadth
