Playbook: diagnose a falling indexation rate in 5 steps
Median healthy indexation (indexed ÷ submitted) sits at 89.4% across 168 audited domains; p10 sites run 61.2%.

Work top-down:
— Step 1: pull Page Indexing report, compute baseline vs. now delta. Drop >5pp ↓ = real, not noise
— Step 2: split excluded reasons. Median offenders: 'Crawled, not indexed' 34%, 'Duplicate, no canonical' 21%, 'Soft 404' 14%
— Step 3: sample 30 URLs per bucket, inspect live. Quality issues cluster ▓▓▓▓▓▓░░░░ ~60% in 'crawled not indexed'
— Step 4: confirm canonical + internal links to affected set (median orphan rate in this bucket: 28%)
— Step 5: re-request indexing only after fix, track 14-day recovery curve

So what: 'Crawled, not indexed' is a quality/uniqueness signal, not a crawl bug — fixing robots won't move it.
