I think this sounds great in theory (and I do agree with you) but depending on how many people you have in the company, you will have sales arguing for one thin

I think this sounds great in theory (and I do agree with you) but depending on how many people you have in the company, you will have sales arguing for one thing, devs arguing for another, product might want another and marketing need the stats to do their job. One of the hardest things is prioritising dissimilar tasks, especially since the return on investment is not always easy to see or might take a number of weeks/months. Maybe the marketing stats really help marketing target more of the right people but maybe they don't or maybe something unrelated stopped the figures from improving after you did the work. I suspect someone has done research on how to add real cost/benefit to some of the intangible things to try and objectively rank them.
