I never have on Google Search (I also block them to be fair), but I've booked a lot of shows through Instagram ads actually. Shows I learnt about only through those ads and I would have been disappointed to miss.
But yeah that's literally the only platform where I've ever had useful ads. Even other meta products only have absolute garbage ads.
Just came here to say the same thing. Local gigs and the like, instagram is actually decent.
And I'm a to-the-bone hater of ads. Ad-blockers up to my eyeballs. Except for that one niche of local gigs on insta.
