Earlier in the week I talked about the best time to send marketing emails, but what about the best time to make social media posts? This is not something where you can segment your audience to run tests, so we might be more dependent on research.
The article The Best Times to Post on Social Media in 2019 According to 25 Studies on the Coschedule Blog is a good place to start. While US-based, I doubt there’ll be any difference here. For B2B social media, they reckon 8am, 10am-12noon and 6pm for LinkedIn; 7-8am, 11am, 6pm and 9pm for Twitter; and 9am and 3-4pm for Facebook. They also suggest any weekday for Twitter, but specifically Wednesday for LinkedIn.
