How I automated 514 paid backlink checks every night

Description and use

Automated nightly check of 514 paid backlinks using n8n and Google Sheets reduced manual effort, identified 11.7 % failures (mostly anchor‑text changes), and improved spend visibility.

Problem

Paid backlink placements need daily verification, but manual checks of 514 pages each night were time‑consuming and often missed anchor‑text changes.

Outcome

The system reduced manual effort from 4–9 hours nightly to automated checks, detected 11.7% failures (mostly anchor‑text rewrites), and highlighted $24,802 of spend tied to flagged placements.

Workflow

• Schedule audit via Google Sheets
• Batch URLs
• Scrape page
• Validate page load, link presence, anchor text, anchor link, nofollow/sponsored/ugc tags
• Classify results
• Write results to Google Sheets
• Email project team with failures

Evidence

514 paid placements are checked every night, automatically. On one night, 60 of them — 11.7% — were flagged.
