Your ROAS in Meta says 4x but Shopify shows 2x — which one is lying?
Niblin monitors every campaign across Meta, Google, and Amazon — flagging ROAS drops, creative fatigue, and budget waste before your weekly review catches it. One agent that watches your ad spend so you don't have to live inside Ads Manager.
Campaign Monitoring
Every campaign watched, every day — without you logging in
Niblin monitors spend, ROAS, CPA, CTR, and CPM across every active campaign. When a campaign that was doing $12 CPA yesterday suddenly hits $28 today, you hear about it in your morning briefing — not three days later when the finance team asks why CAC spiked.
- Daily anomaly detection on spend, ROAS, CPA, CTR, CPM, and conversion rate
- Cross-platform view — Meta, Google, Amazon campaigns in one feed
- Campaign-level root cause analysis: was it the audience, the creative, or the bid strategy?
- Severity scoring so you know the $200/day campaign anomaly can wait, but the $5K/day one cannot
Creative Fatigue Detection
Know when a creative is dying before your ROAS proves it
Creative fatigue is the silent killer of D2C ad accounts. CTR drops 0.2% per week, CPA creeps up, and by the time you notice, you've burned two weeks of budget. Niblin tracks fatigue signals and scores every creative so you can rotate before performance craters.
- Fatigue scoring from 0-100 based on CTR decay, frequency saturation, and CPA trend
- Replacement urgency flags: Low, Medium, High, Critical
- Historical creative performance curves — see exactly when each creative peaked and started declining
- Fatigue alerts in your daily briefing so creative rotation becomes proactive, not reactive
MER & Blended Performance
The one number that tells you if marketing is actually working
Platform-reported ROAS is inflated. You know it. We know it. MER (Marketing Efficiency Ratio) gives you the blended truth: total revenue divided by total ad spend. Niblin tracks MER daily alongside platform ROAS so you always see the gap between what Meta claims and what Shopify confirms.
- Daily MER tracking: total revenue / total ad spend, no attribution games
- Platform ROAS vs MER comparison — see the inflation gap for each channel
- Channel mix analysis: how much of your budget is going where, and what is each channel actually contributing?
- Weekly trend views so you can spot gradual efficiency erosion before it becomes a crisis
Spend Anomalies
Catch the $800 overspend before it becomes an $8,000 problem
Budget pacing issues, unexpected spend spikes, campaigns that auto-scaled past their caps — Niblin flags every spend anomaly the day it happens. Not an end-of-month surprise on the credit card statement.
- Daily spend monitoring against expected pacing for every active campaign
- Automatic alerts when spend exceeds daily or weekly budget thresholds
- Spend vs performance correlation — did the overspend at least produce results?
- Historical spend pattern analysis to set intelligent baselines, not arbitrary caps
Stop discovering budget waste at the end of the month
Connect Meta and Google in 15 minutes. Tomorrow morning, you'll know exactly which campaigns need attention — and which creatives need replacing.
