Google AdMob is one of the most popular monetization platforms for mobile apps. It allows developers to earn revenue by displaying ads within their applications. However, many developers face a frustrating issue: ad serving limits. These restrictions can drastically reduce earnings and stall growth.
In this article, we’ll break down why ad limits happen, how to prevent them, and best practices to keep your AdMob account healthy.

📌 What Are AdMob Ad Serving Limits?
Ad serving limits occur when Google temporarily restricts the number of ads shown in your app. This usually happens due to:
- Invalid traffic concerns – clicks or impressions that don’t come from genuine users.
- Account being assessed – Google reviews new accounts to ensure compliance.
- App not ready to show ads – apps without sufficient organic traffic or proper setup.
These limits can last anywhere from a few days to 30 days, depending on the severity of the issue.

🚨 Common Reasons for AdMob Ad Limits
1. Invalid Traffic
Invalid traffic includes:
- Clicks from bots or automated scripts.
- Developers clicking their own ads.
- Encouraging users to click ads (“Click here to support us”).
- Traffic from incentivized or misleading sources.
Google’s algorithms are highly advanced and can detect unusual patterns quickly.
2. Low-Quality Traffic Sources
Buying traffic from unreliable ad networks or using click farms can trigger limits. Google prioritizes organic installs and genuine engagement.
3. Policy Violations
Examples include:
- Placing ads too close to clickable elements.
- Using deceptive layouts that trick users into clicking.
- Showing ads in apps with prohibited content (adult, violent, or misleading).
4. New Account Assessment
New AdMob accounts often face temporary limits while Google verifies traffic quality. This is normal and usually resolves once your app proves legitimate engagement.

✅ How to Avoid AdMob Ad Limits
1. Build Organic Traffic
- Promote your app through SEO, social media, and app store optimization.
- Avoid buying traffic from shady sources.
- Focus on user retention—Google values apps with consistent, engaged audiences.
2. Follow Ad Placement Best Practices
- Keep ads away from navigation buttons.
- Don’t use deceptive layouts (e.g., placing ads where users expect content).
- Limit interstitial ads to natural breaks in gameplay or app flow.
3. Never Click Your Own Ads
Even one or two clicks from your own device can trigger invalid traffic detection. Always test with test ads provided by AdMob.
4. Avoid Encouraging Clicks
Never use phrases like:
- “Click ads to support us.”
- “Tap here for rewards.”
Google strictly prohibits incentivized clicks.
5. Monitor Analytics
Use Firebase Analytics or Google Analytics to track user behavior. If you notice unusual spikes in traffic or clicks, investigate immediately.
6. Use Mediation and Multiple Ad Sources
AdMob mediation allows you to integrate multiple ad networks. This reduces reliance on a single source and helps maintain healthy traffic.
7. Keep Your App Updated
Regular updates show Google that your app is active and maintained. Outdated apps with poor UX are more likely to face restrictions.

🛡️ Recovery If You Already Have Ad Limits
If your account is already limited:
- Don’t panic—most limits are temporary.
- Focus on improving traffic quality.
- Remove suspicious ad placements.
- Wait for Google’s review cycle (usually 30 days).
During this period, continue building organic installs and avoid any activity that could worsen the situation.
