I've been in go to market for the better part of 20 years now (anyone remember the DigitalOcean youtube ads of the 2012-2014 era?), paid online advertising has basically gone to shit, it started about 6 years ago, but over the past 3-4 years outside of linkedin it's effectively pointless, over 55% of Americans run ad blockers now and around 40% globally - on top of that, what you do get it mostly just... bots. In January I was helping a friend with some of his GTM efforts, we ran $10k over 3 weeks on meta, google, linkedin and X. On Meta, google and X the sub 1 second bounce rate was around 0.7% and hotjar+raw server logs registered zero activity on 99% of the inbound from those platforms, this was to a multitude of ICP specific landing pages with highly targeted ads AND relatively general targeting to the homepage. LinkedIn does still work, but it has gotten extremely expensive.
