How much ad spend is leaking to negative comments?

Comments sit directly under your ad creative and are visible to every impression. When prospects see complaints, scam warnings, or competitor mentions in the first three comments, CTR drops 15–28% and post-click conversion drops another 12–24%. Meta and TikTok both show ads with comments visible by default, so every unmoderated negative comment compounds across the entire impression volume.

BrandBastion published case data showing their enterprise customers saw an average 48% ROAS uplift after implementing AI comment moderation on Meta ads. We use this as the ceiling for the calculator. Your actual lift depends on how aggressive your current moderation is — brands with no moderation in place typically see the largest gains, while brands with manual moderation already running tend to see 15–25% incremental lift when switching to AI.

This calculator is specifically tuned for paid social because paid comments have a direct, measurable dollar impact on ROAS. Organic comment moderation has value too — brand safety, community health, response time — but the ROI is harder to quantify. For organic-focused brands, see our comment moderation ROI calculator which is scoped to time savings and engagement.

FeedGuardians moderates comments on Instagram, Facebook (including Meta Ads), TikTok, and YouTube. Each platform has its own product that hooks into the platform-native comment stream and acts in real time — hiding, deleting, or replying to comments the moment they appear on your ads.

Yes. You can connect a single platform, let FeedGuardians watch your ad comments for 7 days, and see a full report of what would have been hidden. No credit card required for the trial. Most brands see enough harmful comments flagged in the first 48 hours to justify the subscription.
