Your Advantage+ campaign isn't performing. Before blaming the algorithm, systematically debug potential issues. Most underperformance has identifiable causes with fixable solutions.
Debugging Framework
Work through issues in this order — each layer depends on the previous:
- Tracking and signal quality
- Campaign settings and configuration
- Creative quality and diversity
- Competitive and market factors
- Structural limitations
Step 1: Verify Tracking Quality
Check Pixel Events
In Events Manager, verify:
- Events are firing correctly
- Event count matches actual conversions
- No duplicate events
- All funnel steps are tracked
Check Conversions API
- CAPI events appearing in Events Manager
- Deduplication working (not double-counting)
- Customer parameters being passed
Event Match Quality
Check EMQ scores in Events Manager. Low scores limit algorithmic optimization:
- Below 6: Critical issue — fix immediately
- 6-7: Needs improvement
- 8+: Good quality
- 9+: Excellent
If tracking is broken, nothing else matters. Learn about signal importance in our Andromeda optimization guide.
Step 2: Audit Campaign Settings
Existing Customer Definition
Verify your existing customer audience:
- Is the list comprehensive (all purchasers)?
- Is the lookback window appropriate?
- Are engaged non-purchasers included?
- Has the list been updated recently?
Incomplete lists lead to prospecting existing customers or retargeting new prospects.
Existing Customer Budget Cap
- Is the cap set appropriately (typically 20-30%)?
- Is actual spend matching the cap?
- If retargeting is exceeding cap, check audience definition
Conversion Event
- Is the event getting sufficient volume (50+ weekly)?
- If optimizing for Purchase, are there enough conversions?
- Consider moving up funnel if volume is low
Step 3: Analyze Creative Performance
Check Asset Distribution
In Ads Manager, break down by asset:
- How many assets are receiving impressions?
- If only 2-3 assets get delivery, you have diversity issues
- All-similar creative gets bucketed by Andromeda
See our creative diversification guide to understand bucketing.
Creative Quality Metrics
- CTR below 1%: Hooks aren't stopping scroll
- Hook rate below 25% (video): First seconds failing
- High CTR but low conversions: Messaging mismatch
Creative Fatigue Signs
- Frequency above 3 in past 7 days
- Declining CTR week over week
- Increasing CPM with stable delivery
Step 4: Examine External Factors
Competitive Pressure
- CPM increasing without performance change?
- Check if competitors increased spend (Ad Library)
- Seasonal competition shifts
Market Changes
- Has demand for your product changed?
- Seasonal patterns affecting conversions?
- Economic factors impacting purchase decisions?
Website/Landing Page Issues
- Page load speed increased?
- Checkout process broken?
- Product availability issues?
- Price changes affecting conversion rate?
Step 5: Identify Structural Issues
Insufficient Budget
Advantage+ needs budget for learning. If daily budget is too low:
- Campaign never exits learning phase
- Algorithm can't test enough combinations
- Performance remains volatile
Minimum $100/day, recommend $200+/day for stable optimization.
Low Conversion Volume
If weekly conversions are below 50:
- Algorithm struggles to identify patterns
- Consider moving to higher-funnel event
- Or use manual campaigns until volume increases
Learn about volume requirements in our broad targeting prerequisites guide.
Product-Market Fit
Some products don't suit Advantage+:
- Very niche products with small audiences
- B2B products requiring specific targeting
- High-ticket items with long sales cycles
- Products requiring geographic precision
Debugging Checklist
Work through this checklist systematically:
Tracking
- Pixel events firing correctly
- CAPI implemented and working
- EMQ score 7+
- No duplicate events
Settings
- Existing customer list comprehensive
- Budget cap set appropriately
- Conversion event has sufficient volume
- Geographic targeting correct
Creative
- 10+ diverse assets uploaded
- Multiple assets receiving impressions
- Frequency below 3
- CTR above 1%
External
- Landing page functioning
- Product availability confirmed
- Competitive CPM normal
- No seasonal anomalies
How ROASPIG Helps
Many Advantage+ issues trace back to creative. ROASPIG helps prevent and diagnose creative problems:
- Diversity Scoring: Pre-upload detection of bucketing risk
- Fatigue Alerts: Early warning before performance crashes
- Asset Analysis: Understand why certain creative isn't getting delivery
- Rapid Refresh: Generate replacement creative when fatigue signals appear
- Performance Attribution: Connect creative concepts to campaign outcomes
The Bottom Line
Debugging underperforming Advantage+ campaigns requires systematic investigation. Start with tracking (the foundation), then check settings, creative, external factors, and structural fit. Most issues have identifiable causes.
Don't blame the algorithm before verifying your inputs are correct. Advantage+ can only optimize what you give it — tracking signals, audience definitions, and creative assets all need to be working properly.
Frequently Asked Questions About Debugging Advantage+ Campaigns
Common causes: insufficient budget (need $100+/day minimum), low conversion volume (need 50+ weekly), or frequent changes resetting learning. Wait 7 days without changes, ensure budget supports 50 conversions, and verify tracking is working properly.
Your creative is likely too similar, causing Andromeda to bucket them together. The algorithm shows only the top performer from each bucket. Ensure true diversity across hooks, visual styles, and messaging angles — not just surface variations.
Check in order: tracking issues (broken events, CAPI problems), creative fatigue (rising frequency, declining CTR), competitive changes (CPM spikes), or external factors (landing page issues, seasonality). Most sudden drops have identifiable causes.
Advantage+ works best with: 50+ weekly conversions, broad-appeal products, sufficient budget ($200+/day), and strong creative diversity. If you have niche products, very low volume, or need geographic precision, manual campaigns may perform better.
Aim for 7+ minimum, 8+ is good, 9+ is excellent. Below 6 significantly limits optimization effectiveness. Improve EMQ by implementing Conversions API, passing customer parameters (email, phone, name), and ensuring advanced matching is enabled.
