Interesting, I often find the ad selection on Instagram especially abysmal. It might be that my non-US geolocation has a negative effect on this. Most of the ads I get are either generic products for my gender and age range, local industry companies wasting budget on stuff I'm interested in but don't need at scale and won't ever buy through Instagram links, useless recruiting startups aimed at what I assume would be me 15 years ago (and even then I was not interested in this form factor), and of course a wide range of scams from personal finance to Kickstarter products.
