Hi HN,I'm hoping to gather some ideas to help me quantify the impact (immediate and long term) of advertising campaigns in a mobile app.I currently work on an ad supported product with a fledgling ads team that so far has a less than stellar track record of balancing customer experience with ad impressions. This frequently leads to ads that I feel degrade the overall quality of the experience but is hard to measure.The main challenge is that monetization is an easily digestible metric directly related to how many ads we sell and show. What I would like is to be able to do is balance this metric with the impact of a degraded experience or user engagement.Has there been any research done on the topic that I can use to base my analysis? Are there common metrics being used to weigh the trade offs of additional ad slots that others have found effective?Since we are a new team I'm hoping I can help establish some standards early in our product's life to help minimize the longer term impact of too many ads. I'd like to establish a common language between ad and product teams that we can use in decision making.
