ROHAN
So how often should an actor post on social media?
SEAN
Rohan, this is a great question but very broad so I'm going to try and be as general (& specific) as possible in as little as possible as each social media channel can have it's own post!
PURPOSE
How often you post will depend on the purpose of your social media channels. As channels in their own right, they already have their own purposes but how and why you're using them is up to you.
Twitter you can afford to post as often as you like and "spam" your followers because the feed on Twitter has such a high turnover that whatever you posted 5 - 10 mins ago will be 3 or 4 scrolls down the feed!
With Facebook, I'd suggest taking it a bit easier and posting when you have something you really want to say or share with those in your network (or friends list).
On Instagram, I find a minimum of once per day is enough when posting at the right time for your audience. I personally wouldn't post any more than 3 times a day (as a performer) because it COULD become overwhelming to your audience/ followers but again this depends on the purpose of your Instagram.
For example, I post once a day, around 6:30pm my local time because that's when I have the most active audience in a given 24 hour period. Anything more, both my feed and my gram gets overwhelmed. Any less makes it look like I don't exist.
CHECKLIST:
Why am I using social media?
What is the best WAY to post on each different channel I own?
When is my audience the most active on that day for that channel?
