Yes. The best time to post on social media is whenever your audience is most likely to see and engage with your content. A well-timed post can lead to more likes, comments, shares, and click-throughs.
But, timing varies depending on industry and your specific audience.
Earlier is generally better (mornings)
After the work day is generally a bad time, except for Instagram
Thursday is the BEST day to post for every platform
Weekends are a bad time to post (except weekend afternoons on Facebook)
