Troubleshoot low match rate
Your apps may experience less demand from Google while we evaluate your traffic quality. This can occur for up to a week after a new app or ad unit is created.
Wait one week before seeking additional help. If you’re still seeing low match rate after one week, review the following tips:
- Check your implementation. Learn more.
- Review recent changes to your account to determine if they may be contributing to low match rate.
- Review your blocking controls. Blocking any ad will lower your match rate, as it reduces competition for your ad space by removing advertiser bids from the auction.
- Check your maximum ad content rating. Adjusting the size of your audience can affect your revenue.
- Review your floor settings. High floors can lead to limited match rate.
Ad serving changes
- Check the Policy center to see if you have any violations that could impact your ad serving. Resolve all violations to ensure that ad serving continues.
- Understand that apps used by younger audiences and families can have lower match rate due to smaller age appropriate advertiser demand and restrictions imposed by laws and regulations like the Children's Online Privacy Protection Act (COPPA).
- Review Google's Trust & Safety initiatives to determine if your app may be affected.
- Review any changes you’ve made to your app to ensure they’re not causing the issues.
- Check for crashes and application not responding (ANR) errors for your apps (Android, iOS).
- Use your reports to check key metrics. For example, review the daily active users metric to understand if less users are accessing your app.
- Check if users had a regional holiday. Holidays can affect traffic, which can affect your earnings. Use your reports to filter by country and by date range.
- Look at the bigger picture. Has there historically been a drop or spike in metrics at this time of year? Use your reports to expand the date range of the report.
