Facebook Ads Andromeda Algorithm: Common Issues & Quick Fixes

Since Facebook's Andromeda algorithm rolled out, two problems keep appearing in communities and among our agency clients:

1. Accounts over-reliant on precise targeting are getting crushed (especially in ecommerce—some clients literally can't spend their budgets anymore)

2. Evergreen creatives that worked for months suddenly stopped performing

If you're experiencing sudden CPA spikes, conversion drops, or creative fatigue, you're not alone.

We've compiled solutions from our community, international forums (especially Reddit), and our own testing to help you fix these issues fast.

Understanding the Andromeda Shift

Old Method: Precise targeting—you tell Facebook exactly who to show your ads to.

New Method: Broad AI matching—the algorithm finds the right people within a massive audience pool.

This isn't just a minor tweak. It's a fundamental change in how Meta's ad delivery works.

What this means for you:

• ✅ Less manual targeting work
• ✅ Potentially better performance (if you adapt)
• ❌ Old strategies that worked for years may fail overnight
• ❌ You need high-quality data and fresh creatives

Let's tackle the two most common problems.

---

Problem A: Extreme Dependency on Precise Targeting

Symptoms:

• CPA suddenly increased by 50-200%
• Conversion volume dropped sharply
• Budget not spending (especially common in ecommerce)
• Performance was stable for months, then crashed after Andromeda

Why This Happens:

Andromeda's AI wants broad audiences to explore and learn. When you force it into narrow targeting boxes (e.g., "Women 25-34, interested in yoga, living in California"), you're limiting the algorithm's ability to discover high-intent users outside your assumptions.

The algorithm is essentially saying: *"I can find better customers than you think, but you won't let me."*

---

Quick Fix (0-14 Days)

1. Consolidate Similar Audiences into 1-2 Broad Campaigns

Action:

• Merge your narrow audience segments (e.g., "Yoga enthusiasts," "Fitness lovers," "Wellness seekers") into one broad audience or just use no targeting at all (age/gender/location only).
• Launch 1-2 broad audience campaigns as your primary spend.

Why it works:

• Gives the algorithm a larger sample pool to learn from
• Allows AI to discover patterns you didn't anticipate

Example:

---

2. Enable Advantage+ Dynamic Creative (or Dynamic Creative Optimization)

Action:

• Turn on Advantage+ Creative or Dynamic Creative in your ad sets
• Upload multiple headlines, primary texts, descriptions, images, and videos
• Let the system auto-combine and test variations

Why it works:

• Gives the algorithm more creative flexibility to match different user preferences
• Speeds up learning phase

How to enable:

• Ad Set level → Advantage+ Creative → Toggle ON
• Upload 3-5 headlines, 3-5 primary texts, 2-3 images/videos

---

3. Check and Fix Your Pixel / Conversions API (CAPI)

This is critical. Missing or broken event data severely weakens the algorithm's ability to learn.

Action:

• Go to Events Manager → Check your Pixel event status
• Verify Conversions API (CAPI) is set up and firing correctly
• Check Event Match Quality score (aim for "Good" or "Great")
• Ensure key events (Purchase, Add to Cart, Initiate Checkout) are firing

Why it works:

• Andromeda relies heavily on conversion signals to optimize
• Poor data = poor performance

Common issues:

• Pixel not firing on thank-you page
• CAPI not configured (server-side tracking)
• Events firing but with low match quality (missing user data like email, phone)

💡 Pro Tip: Use Adfynx's AI Audit feature to automatically detect Pixel and CAPI issues. It scans your setup and flags missing events, low match quality, and tracking errors—saving you hours of manual debugging.

---

Mid-Term Adjustments (15-60 Days)

1. Keep One Small Precise Targeting Control Group for A/B Testing

Action:

• Allocate 10-20% of budget to a precise targeting ad set (your old method)
• Use it as a control group to compare against broad targeting

Why it works:

• Validates whether broad targeting is truly better for your business
• Provides data-driven proof for stakeholders

---

2. Build a Creative Asset Library with Variations

Action:

• Take your top-performing creatives and create 5-10 variations:

- Different hooks (first 3 seconds)

- Different CTAs (Shop Now vs. Learn More)

- Different thumbnails

- Different aspect ratios (1:1, 9:16, 16:9)

Why it works:

• Broad audiences need diverse creatives to appeal to different user segments
• Reduces creative fatigue

Example Variation Strategy:

---

3. Use Adfynx's Creative Intelligence to Identify Winning Patterns

Instead of guessing which creative variations work, Adfynx's Creative Intelligence analyzes your ad performance and tells you:

• Which visual styles drive the most conversions
• Which hooks get the highest engagement
• Which CTAs lead to purchases

How it helps:

• Saves time on manual creative analysis
• Identifies patterns across hundreds of ads instantly
• Guides your next creative production

---

Long-Term Optimization (60-90 Days)

Optimize for Lifetime Value (LTV) / Repeat Purchases

Action:

• If your business has repeat customers, shift optimization from Purchase to Value-based events (e.g., high LTV customers)
• Use Value Optimization in campaign settings

Why it works:

• Teaches the algorithm to find customers who spend more over time, not just one-time buyers
• Improves long-term ROAS

How to set up:

• Campaign Objective → Sales
• Optimization Event → Purchase (Value)
• Ensure your Pixel sends purchase value with each transaction

---

Problem B: Evergreen Creatives Suddenly Failing

Symptoms:

• CTR dropped by 30-50%
• Engagement (likes, shares, comments) declined
• Ads that ran successfully for 3-6 months stopped working
• Frequency is normal (not creative fatigue from overexposure)

Why This Happens:

Andromeda's AI is more aggressive about creative freshness. The algorithm now penalizes repetitive or stale creatives faster than before, even if they're not overexposed.

The algorithm is essentially saying: *"I've shown this creative to everyone who might care. Give me something new."*

---

Quick Fix (0-14 Days)

1. Prepare 6-10 Creative Variations Immediately

Action:

• Create 6-10 new video and image variations
• Prioritize:

- UGC (User-Generated Content) or real people (not polished brand videos)

- Vertical videos (9:16 for Reels/Stories)

- Short-form (under 15 seconds)

Why it works:

• Fresh creatives reset the algorithm's learning
• UGC and vertical videos align with Meta's current platform priorities (Reels)

Quick production tips:

• Film with a smartphone
• Use real customers or team members (not actors)
• Focus on authentic, relatable content

---

2. Remix High-Performing Segments from Old Creatives

Action:

• Take your best-performing old creative and create new edits:

- Different opening (first 3 seconds)

- Different CTA (end screen)

- Different thumbnail (static image preview)

- Different music/voiceover

Why it works:

• Leverages proven messaging while appearing "new" to the algorithm
• Faster than creating entirely new concepts

Example Remix Strategy:

---

3. Use Adfynx's Smart Reports to Spot Creative Fatigue Early

Don't wait for performance to crash. Adfynx's Smart Reports automatically track:

• CTR trends over time (flags when CTR drops 20%+)
• Frequency by creative (alerts when a creative is overexposed)
• Engagement decay (shows when likes/comments slow down)

How it helps:

• Get early warnings before performance collapses
• Know exactly which creatives to refresh
• Avoid wasting budget on dying ads

---

Mid-Term Adjustments (15-60 Days)

1. Establish a Weekly Creative Iteration Plan

Action:

• Set a recurring calendar reminder to review creative performance every Monday
• Replace bottom 20% of creatives each week
• Launch 2-3 new creative tests weekly

Why it works:

• Keeps your creative library fresh
• Prevents sudden performance drops

Weekly Creative Checklist:

• ✅ Review CTR and engagement for all active creatives
• ✅ Pause creatives with CTR below account average
• ✅ Launch 2-3 new creative tests
• ✅ Analyze top performer and create 1-2 variations

---

2. Use Creative Layering: Test 3 Parallel Tracks

Action:

• Run three creative testing tracks simultaneously:

1. Visual Differentiation Track: Test different visual styles (animation vs. live-action, bright vs. dark, minimalist vs. busy)

2. Emotional Appeal Track: Test different emotions (fear, joy, curiosity, urgency)

3. Feature/Benefit Track: Test different product angles (price, quality, convenience, status)

Why it works:

• Diversifies your creative portfolio
• Discovers which messaging resonates with different audience segments

Example:

---

Long-Term Optimization (60-90 Days)

Build a Quarterly Creative Production Matrix

Action:

• Plan 90 days of creative production in advance
• Maintain a creative asset library with at least 30-50 ready-to-launch variations
• Establish a repeatable production process (e.g., monthly UGC collection, bi-weekly in-house shoots)

Why it works:

• Ensures you never run out of fresh creatives
• Reduces last-minute scrambling
• Improves creative quality through consistent iteration

Quarterly Creative Matrix Example:

---

What the Community Is Saying

Success Stories (from Reddit & Communities):

Case 1:

"Switched to broad audience + 10 creative variations. Ran for 2-3 weeks. ROAS went from 1.8 to 3.2—higher than our historical best."

Case 2:

"We were stuck at $80 CPA. Merged 5 narrow audiences into 1 broad campaign, fixed our CAPI setup, and CPA dropped to $45 in 10 days."

---

Common Concerns:

Concern 1: *"The algorithm is only spending on 2-3 creatives. Is this broken?"*

Answer: This is normal exploration vs. exploitation behavior. The algorithm is testing, then concentrating budget on winners. Give it 7-14 days and more creative variations to test.

---

Concern 2: *"Broad targeting is showing my ads to irrelevant people."*

Answer: In the first 3-7 days, yes. The algorithm is exploring. After the learning phase, it will narrow down to high-intent users. Trust the process, but monitor your Pixel data quality.

The future of advertising is returning to its roots: Creative is king again.

The algorithm handles targeting. Your job is to:

• ✅ Feed it high-quality data
• ✅ Supply fresh, engaging creatives
• ✅ Optimize for long-term value

The opportunity: Advertisers who embrace broad AI matching and invest in creative production will outperform those clinging to old methods.
