There is no "best time to post" on any social media.
Any study that claims to reveal the perfect time to post on any social media platform is, instead, revealing the mathematical results of an algorithm they used to calculate certain (possibly beneficial) outcomes at one particular moment in time, for some general group of posters.
No one can possibly tell you when the bulk of your followers and potential followers will be ready to receive your message. There is no calculation to allow one post to be carefully planned to accomplish more than some other post.
Here's what works: consistent persistent personal relevant content.
Always has. Always will. No trickery or algorithms needed.

It wasn't personal.
It wasn't anticipated.
When the level of relevance reaches 100% personal and anticipated can drop to zero and the message will still be appreciated.

If you were to ask us why you get Ausoma's newsletter, we could tell you that there are only two possible ways: you signed up for it yourself at the website, or you asked to be on the list.
We didn't add you just because we wanted to.
We didn't get your business card at a mixer, and add you to our list without telling you.
We didn't sell you a book, and add you to our list without telling you.
We didn't connect with you on Facebook, LinkedIn, Twitter, Pinterest, or Bob's Social Media and Lawnmower Repair, and add you to our list without telling you.
