Two of the questions I get asked the most are ‘When is the best time to post on LinkedIn and ‘How often should I be posting content on LinkedIn’? Content on LinkedIn and other social media has an expiration date. Whenever something is posted, there is a period of time before it gets lost in the masses of content uploaded every minute. So it is very important to have a clear understanding of how long this lifespan is, so you know exactly when and how frequently to post.
