Could some of this be because the given timelines are too short? They gave the example of Chase, which moved from 400,000 digital ads to only 5,000, but they declared there was no significant difference in business after "only a few days." As a person who has never used Chase, I'm not going to suddenly want to switch to them just because I saw a banner ad. That would be ridiculous. It's the sum of all the Chase advertisements I've seen in the past decades that have made me believe they're a popular and trustworthy bank.
