What’s the difference between a post, a pillar and a campaign?

A post is what you publish on your social media account. A content pillar is a regularly repeating post format as in “leadership post 1x a week on Thursday” – it will mark itself in the calendar accordingly. A campaign is a) a way to create focus points for your brand story and b) a way to organize and schedule your posts accordingly. For example: Campaign: Valentine’s Day; Posts: ‘Love is in the air’, ‘Special discount’, etc.
