"One weird trick" (also "one simple trick") advertisements are a form of
clickbait online advertising that has been common on the
Internet since around the late 2000s. The formula used in the
advertisements was first applied to
weight-loss products, but has since been extended to cures for problems including
hair loss and
diabetes.[1][2] A
Federal Trade Commission (FTC) investigation found that many of the advertisements sold "trial" packages that were never sent. The FTC filed legal action in 2011 against promoters of such advertisements for
defrauding millions of people.[3][4]
