It’s not unusual for Google to remove reviews in bulk during automated spam sweeps. This can impact both negative and positive reviews.
Common reasons reviews disappear
- Spam-filter updates (Google re-evaluates older reviews).
- Reviewer account issues (accounts suspended, content removed).
- Location/GBP changes (merges, address edits, category changes).
- Policy enforcement (Google removes content deemed in violation).
What you should do
- Document the change (screenshots, dates, review count before/after).
- Check for business profile changes around the same time.
- Review acquisition health (avoid sudden surges or incentivized requests).
- Escalate if needed with clear, factual notes.
When to get help
If review volatility is affecting revenue or ad performance, it can be worth doing a structured audit: what is being removed, why, and how to stabilize your profile’s trust signals.
