Tips for solving performance issues
Many factors can affect whether your ads receive impressions, including relevancy, max CPT bid amount compared with your competitors, and the number of times customers on the App Store search for apps like yours.
Impressions aren’t guaranteed, but you can do a few things to improve your chances:
Increase your maximum cost-per-tap (max CPT) bid.
Many developers raise it gradually while tracking results. You can refer to our suggested bid range and bid strength indicators as guides.
Turn on Search Match.
This will enable automatic search term matching for your ad group.
Analyze Search Match results.
Doing so can help you identify search terms that are performing well. Once you know which terms work, add them as keywords at a higher max CPT bid.
Turn off or limit audience refinements.
This can help to expand your reach by displaying your ads to a broader audience.
Check your cost-per-aquisition (CPA) goal.
If you set your CPA goal too low or below your max CPT bid, you may miss out on valuable impressions and conversions.
