In June, 2021, Pieter bought a billboard in front of Apple’s headquarters. He used a service called Blip to do this for $24.46. The billboard got 1.5+ million views to Remote OK. This equalled 1.6¢ per 1,000 views.
The real value didn’t lie with the billboard itself. The tweet announcing the billboard went viral and got a lot of attention in the indie hacking community.
Pieter promoted the Tweet on Twitter. It got 311,220 extra views for $500 ($1.60 per 1,000 views.)
Blip later said that the campaign received an estimated 57,000 impressions with an average daily spend of $18.
