This is exactly what I see with every local client 📍
The spam surge isn't a tactic failure - it's the cost of visibility. Here's the breakdown:
📞 NAP data is public by design - Google Business Profile, Yelp, industry directories, even your domain WHOIS all publish that phone number. Scrapers hoover it up instantly.
🔄 Lists get resold - Those aggregated datasets change hands constantly. Your number hits spam call centers before you've even finished onboarding the client.
⚖️ Same pipe, different traffic - The legitimate leads and the robocalls arrive through the exact same channel. You can't separate them at the source.
🛡️ Mitigation, not elimination - Call filtering, auto-attendants, blocking known offenders - all help. But pulling the number off listings tanks local rankings. Been there, tested that.
So if a client's phone starts blowing up the week their GBP goes live? That's the system working, not broken SEO.
