An example of this design experimentation is in the FTC’s action against Credit Karma.16 Credit Karma advertises thirdparty financial products, such as credit cards, and provides links for consumers to apply for offers. Credit Karma conducted A/B testing, which is an experiment where a company shows consumers two or more variants of something, such as an advertisement or a webpage, to determine which one performs better. Credit Karma compared how consumers reacted to being told that they had been “preapproved” for a credit card (a false claim, according to the FTC’s complaint) versus being told that they had “Excellent” odds of being approved.The company ultimately decided to employ the allegedly false “preapproved” claim, which the A/B testing had shown yielded a greater click rate.17
