Query: Do Users Care about Ad's Performance Costs? Exploring the Effects of the
  Performance Costs of In-App Ads on User Experience   Context: In-app advertising is the primary source of revenue for many mobile
apps. The cost of advertising (ad cost) is non-negligible for app developers to
ensure a good user experience and continuous profits. Previous studies mainly
focus on addressing the hidden performance costs generated by ads, including
consumption of memory, CPU, data traffic, and battery. However, there is no
research onanalyzing users' perceptions of ads' performance costs to our
knowledge. Objective: To fill this gap and better understand the effects of
performance costs of in-app ads on user experience, we conduct a study on
analyzing user concerns about ads' performance costs. Method: First, we propose
RankMiner, an approach to quantify user concerns about specific appissues,
including performance costs. Then, based on the usage traces of 20 subject
apps, we measure the performance costs of ads. Finally, we conduct correlation
analysis on the performance costs and quantified user concerns to explore
whether users complain more for higher performance costs. Results: Our findings
include the following: (1) RankMiner can quantify users' concerns better than
baselines by an improvement of 214% and 2.5% in terms of Pearson correlation
coefficient (a metricfor computing correlations between two variables) and NDCG
score (a metric for computing accuracyin prioritizing issues), respectively.
(2) The performance costs of the with-ads versions are statistically
significantly larger than those of no-ads versions with negligible effect size;
(3) Users are moreconcerned about the battery costs of ads, and tend to be
insensitive to ads' data traffic costs. Conclusion: Our study is complementary
to previous work on in-app ads, and can encourage devel-opers to pay more
attention to alleviating the most user-concerned performance costs, such as
battery cost.
