Health Check for experiments provides a series of diagnostics and checks to improve the probability of conclusive experiment results when you create a new app uplift experiment.
This article explains what issues Health Check may reveal and ways to fix those issues. We recommend that you fix severe issues (shown in red), such as using an iOS app (currently not supported), and try to fix moderate issues (shown in yellow) as best you can, such as the budget being too low.

App OS |
App uplift experiments currently only support Android apps. |
Choose an Android app |
|
Limited by budget |
If your campaign is limited by budget, it's unlikely that your testing assets will be able to get sufficient traffic for conclusive experiment results. |
Raise your budget |
|
Bid too low |
If your campaign is limited by your bids, it's unlikely that your testing assets will be able to get sufficient traffic for conclusive experiment results. |
Raise your target CPA or target ROAS |
|
Budget too low |
If your campaign budget is too low, it's likely that your testing assets will get a low number of conversions, which can limit how well our models can optimise your experiment. |
Raise your budget |
|
Confidence level |
The confidence level you chose may be too high relative to the campaign’s budget, which could cause your experiment to run longer than it should. |
Lower the confidence level |
|
Experiment duration |
The duration you set for your experiment is probably too short relative to the selected base campaign budget and the confidence level selected. This could prevent your experiment from delivering statistically significant results. |
Increase the duration of your experiment or lower the confidence level |
