My account is poetry/quote account, It's on Croatian language, and its also run from Croatia, but with my range of followers i found out they follow me from all over the world, mostly Europe, but even USA! (Since my passion is writing, I also post on English sometimes, every post I made, Its made by myself , they are not copied in any way!)
I can post a shoutout any time you think is okay, for me, best time is around 6-11pm ( Central European time).
As for my insights, weekly I have over 500k , sometimes close to 1m impressions. On photos i get between 2k-4k likes, on stories around 16k-20k.
