This lengthy piece from The Correspondent, about the (in)effectiveness of digital advertising, might have you killing your Facebook ads ☠️
An excerpt:
Economists at Facebook conducted 15 experiments that showed the enormous impact of selection effects. A large retailer launched a Facebook campaign. Initially it was assumed that the retailer’s ad would only have to be shown 1,490 times before one person actually bought something. But the experiment revealed that many of those people would have shopped there anyway; only one in 14,300 found the webshop because of the ad. In other words, the selection effects were almost 10 times stronger than the advertising effect alone!
[…] In seven of the 15 Facebook experiments, advertising effects without selection effects were so small as to be statistically indistinguishable from zero.
Definitely read the full thing if you buy or sell any kind of online advertising.
