Case: noindex on 41,000 thin ZIP-code pages lifted sitewide clicks 34%

Case: noindex on 41,000 thin ZIP-code pages lifted sitewide clicks 34%

Client had 58,000 location pages. 41,000 had under 12 unique words and zero bookings in 90 days. Action log:

— Step 1 (analyst): pulled GSC index report, flagged URLs with 0 impressions over 90 days. Gate: 0 impressions = candidate.
— Step 2 (analyst): cross-checked against revenue table. Gate: 0 bookings = confirm prune.
— Step 3 (dev): set X-Robots-Tag: noindex on 41,000 confirmed URLs, kept them live for users.
— Step 4 (dev): removed them from sitemap, left internal links intact.
— Step 5 (analyst): monitored 'Crawled — not indexed' for 6 weeks.

Outcome at week 8: indexed pages dropped from 58k to 17k. Sitewide clicks +34%. Average crawl-to-index latency on new pages fell from 9 days to 2.

Guardrail: never delete, only noindex first — rollback is one header flip.

Ship gate: don't publish until all boxes are checked.
