Frequency means how often a business sends messages, posts content, or shows ads to the same audience. Getting this right matters a lot. Post too little and people forget you exist. Post too much and people get annoyed and unfollow or unsubscribe. There is no single correct number, but most businesses find that one to two posts a day on social media and one or two emails a week is a good starting point. What works also depends on the platform. Audiences on Twitter or X expect more posts than audiences on LinkedIn. How do you think a business should decide the right posting frequency for its audience?
