>This is more complex than financials - displaying an advert leads to a bi-directional association in the consumers mind between the entity being advertised and the entity advertising it. It is beneficial to advertise products that have Brand values similar to yours (or ones you want to appropriate).
I agree, and I think that's part of why I disagree so hard with you on the primacy of images.
I mean, i'm not saying that a preference for text vs. a preference for pictures is objectively right or wrong, it's just a really good example of your aforementioned alignment of brand values between the content provider, the brand doing the selling, and the consumer. pictures are a way of associating your brand with values, but eschewing the (possibly extraneous) extra data in that picture, you are also associating your brand with a set of values.
I am also a consumer of protein powder... but you are way better off appealing to me with text. Ingredients, (tell me what the stuff is made of, and don't add any sweeteners) purity (Test for heavy metals or the like!) and then price are probably the attributes you want to bring forward, if you are trying to sell me a protein powder, approximately in that order. If you instead show a nice picture of the can or have a model preparing some in your ad, I'm going to see that, at best, as an irrelevant distraction. (again, I'm not saying those are the objectively most important attributes of a protein powder, but if you want my protein powder budget, that's how you get it; At a cultural level, the more I feel you focus on the things I care about and the less you focus on things I see as irrelevancies, the more I feel you align with my values.)
I mean, I'm not saying that pictures are good or bad in general, just that advertising with pictures and advertising with text have very different cultural connotations, and that advertising with text only can be a striking alignment with a consumer's values.
