# Indexation Recovery Engine Diagnoses why Google chose not to index pages and proposes specific recovery actions per failure mode. Combines GSC coverage states, on-page heuristics, internal-link graph analysis, and Indexing API requests into a single workflow. ## Why this matters Real-world incident on miyakodeit.com (2026-05-27 audit): - Submitted: 93 URLs - Indexed: 34 (37%) - "Discovered - not indexed": 50 - "Crawled - not indexed": 4 (including `/blog` top index page!) - "URL unknown to Google": 3 Pages outside the index produce zero search traffic regardless of how good their content is. Most indexation failures are recoverable with concrete actions (not "wait and hope"). ## Failure mode classification The skill classifies each unindexed page into one of these modes and prescribes specific actions: | GSC Coverage State | Failure Mode | Recovery Strategy | |---|---|---| | Discovered - currently not indexed | Quality threshold not met (Google deprioritized) | Strengthen internal links + add unique data/quotes | | Crawled - currently not indexed | Content judged thin or duplicate | Rewrite intro 200 tokens, add original research | | Alternate page with canonical | Canonical mismatch | Verify HTML canonical, force recrawl | | URL is not on Google | Not discovered yet | Add to sitemap + internal link from indexed page | | Excluded by 'noindex' tag | Intentional | Skip (verify intent) | | Blocked by robots.txt | Blocking issue | Verify robots.txt allow rules | | Soft 4
