Depends on the niche and page optimization. With 1000 story likes per day in the babes niche, you can expect to see around 100 followers a day average. 250+ on a good day and 50 on a bad day. In personal branding niche you can expect to see something like 25-100 followers a day with a well optimized HQ page. I’d say 50 followers a day average maybe a little lower. Around 100 on a good day but a bad day could be like 10. This is from my own experience
