How and When to Post on Facebook, Twitter, Instagram, Pinterest, and LinkedIn

Updating your social media profiles too frequently or infrequently can alienate your target audience, leaving you ignored or unseen by your followers. This is why understanding when your audience is active on social media can help you increase shares, traffic, and links.

While the best days and times to publish a blog post are Monday through Thursday, between 8 am and 1 pm in the time zone where most of your readers live, social media follows a different rhythm. The simplest way to think about the best time to post on social media is to analyze when people are bored or tired at work or school.
