Do users care about ad’s performance costs? Exploring the effects of the performance costs of in-app ads on user experience

•We propose RankMiner, a method for automatically prioritizing users’ concerns towards app issues from user reviews.•We find that performance costs of with-ads versions are significantly larger than those of no-ads versions.•We find that users are more concerned about the battery costs of ads, and tend to be insensitive to ads’ data traffic costs.•We open-source our code https://remine-lab.github.io/adbetter.html for replication and extension of our work.
