I've noticed that when you prepare the scene, background, extra elements (sometimes), and of course, cookie quality and original designs gets to be more eye-catchy. Also, I've noticed that when I post a picture on my Facebook page (you get to schedule a time and date for your post to be automatically posted) I try to choose evenings, for the simple reason that at that time of the day (let's say from 10 am to 4 pm) it's the time when people have spare time (lunch, break) to check Facebook or social media in general. But I'd say that the best time to post is between 1 pm to 8 pm, plus I'd like to recommend you all to get an Instagram account, hashtags make your posts more popular, and videos are deeply appreciated!
