Hi @Colber0 Sometimes following other Airbnbs is just a gesture of goodwill, and that's never a bad thing. But almost nothing you do on Instagram will result in instant noticeable increase in bookings. Airbnb has a much bigger reach than most individual Instagram accounts ever will!
On my Instagram, I follow as many local businesses as possible - restaurants, shops, galleries - as well as the accounts of all the small towns around, the chambers of commerce, and the land trusts (they administer all the hiking trails). I also follow Instagrammers who take wonderful photos of the region. They usually have a lot of followers and you'll get more followers through interacting with them.
