Case: PDF whitepaper dead citations → 5 links
Whitepapers and reports cite external URLs in footnotes that rot. Nobody checks PDFs.
1. Search filetype PDF + your topic across industry sites (60 reports collected).
2. Extract every URL from each PDF, status-check (1,900 citations, 240 broken).
3. QA gate: keep breaks where you have an equal-authority replacement (33 qualified).
4. Email the report's author/org: 'Footnote 14 in your report links a dead source, here's a current one.'
5. Batch 10/day.
Result: 5 links, plus 2 orgs cited you in their next report revision.
Definition of done: 60 PDFs parsed, 33 breaks contacted, logged.
Automation fits at steps 1-2 (PDF URL extraction). Low competition — almost no one mines PDFs.
