Twitter offers a few guidelines to consider for your business’s content strategy.
How often should I tweet?
It depends on your business, but Twitter suggests establishing a regular cadence of tweeting so your followers know when they are going to get updates from you.
What is the best time to tweet?
We’ve seen that there is double* the engagement rate when Tweets are published during the day (8AM – 7PM). However, consider tweeting throughout the day to reach different time zones.
Which day of the week should I tweet on?
Test multiple days of the week to see what works best. Saturdays and Sundays may have a higher engagement rate as that is when most people are not at work.
