When managing BIGO Ads, many advertisers experience a consistent pattern: campaigns stabilize for a few days or weeks, then suddenly lose delivery, with CPC rising, CTR falling, or traffic becoming unstable. These delivery drops occur at different stages of the account lifecycle, and solving them effectively requires understanding the underlying mechanisms of the BIGO Ads algorithm.
This article provides a systematic breakdown of the causes of traffic decline at each stage and detailed solutions, supported by industry data, practical experience, and platform behavior research. The goal is to help advertisers stabilize their accounts, maintain continuous delivery, and scale sustainably.

Overview: Why BIGO Ads Accounts Experience Delivery Drops
Based on aggregated data from 42 BIGO Ads advertisers and internal campaign data analysis (Novabeyond Research, 2024–2025), the most common causes of delivery decline include:

Key Insight:Different stages → different dominant causes → different solutions.
Stage 1: Learning Phase (Day 1–7)
Why Traffic Drops in Early Stage
Common reasons:
1. Too many edits during the early phase can reset the algorithm’s learning.
2. A budget that is too low may prevent the algorithm from collecting sufficient learning data.
3. Overly restrictive targeting, reducing traffic reach
4. Using competitive placements too early

Solutions
Stage 2: Stable Delivery Period (Day 7–30)
Once the ad stabilizes, performance is predictable until fatigue begins.
Typical Causes of Drop
1. Creative fatigue (most common)– CTR drops by 20–35% after 7–14 days
2. Audience saturation– The system re-shows ads to repeat users
3. Bid not keeping pace with market fluctuations
4. Competition spikes during certain hours/days
5. Small edits accidentally restarting the learning phase
Data Indicators of Fatigue
| Metric | Signal |
| CTR ↓ 15%–30% | Fatigue started |
| CPM ↑ 10%–20% | Competition rising |
| CVR ↓ | Traffic quality declining |
Solutions
Stage 3: Scaling Phase (≥ 30 Days)
When advertisers increase budgets rapidly, account instability is common.
Why Delivery Drops During Scaling
1. Budget increased too quickly (>30% jump triggers re-learning)
2. Scaling before creatives reach high confidence
3. Too many low quality new campaigns launched in short time
4. Insufficient attribution data → algorithm loses clarity
5. Cross-campaign bidding conflict
Industry Benchmark
Campaigns that scale using 20% daily increments maintain a 28% higher stability than campaigns that scale >40% suddenly.

Solutions
Stage 4: Long-Term Operation (60–180 Days)
This stage involves account-level health management.
Common Structural Causes
1. High number of rejected ads affecting the account
2. Sudden policy changes
3. Platform-level throttling during risk review
Data Insight
Accounts with ≥10 rejected creatives in 60 days experience an average 25% traffic throttling for the following 7 days.
Solutions
Advanced Troubleshooting (All Stages)
(1) Creative-Level Fixes
(2) Campaign-Level Fixes
(3) Audience-Level Fixes
(4) Optimization Window Setting
When to Use Agency Ad Accounts (BIGO Ads Agency Account vs. Self-Serve)
Understanding these patterns enables advertisers not only to take proactive measures to maintain campaign performance but also to anticipate potential delivery drops before they impact ROI. By applying stage-specific optimization strategies—such as refreshing creatives, adjusting budgets incrementally, and expanding audiences—advertisers can achieve more stable and sustainable growth.

Conclusion
Delivery decline is not random; it follows identifiable patterns at each campaign stage. Once advertisers understand the causes and apply the correct optimization strategy, stability improves dramatically, and long-term scaling becomes achievable.
FAQ
Q1: Why does my BIGO Ads campaign stop delivering suddenly?
Because the algorithm enters re-learning due to edits, budget jumps, or creative fatigue.
Q2: How long does BIGO Ads learning phase last?
Typically 5–7 days, depending on data volume.
Q3: How often should creatives be refreshed?
Every 5–7 days depending on CTR and CPA stability.
Q4: Should I scale with budget increase or duplication?
