Detect offboarded client links on PBN sites with Google Sheets and HTTP

Automatically scan every PBN site in your Google Sheet, check if any removed client domain is still linked in the live HTML, and log all matches back into your tracking sheet — row by row, hands-free.

What this workflow does

Managing a network of PBN sites becomes risky the moment a client project gets offboarded. If the old link still exists on a PBN page, it can trigger a Google penalty, waste crawl budget, or simply point to a dead destination. Manually checking each PBN every time a project is removed is slow and error-prone.

This workflow solves that completely. It reads your full PBN list from Google Sheets, skips any site you have already checked, then loops through each remaining PBN one at a time. For every site, it fetches the live HTML using an HTTP request, pulls your current list of offboarded project domains from a separate sheet, and runs a domain-matching check directly against that HTML. If a match is found, the workflow writes the detected domain into the "Offboarded Links" column automatically. It then pauses briefly and moves to the next PBN — no manual work required at any stage.

Perfect for SEO agencies and link builders who manage multiple PBN networks and need a reliable, automatic way to keep their offboarding records up to date.
