The document outlines a method for determining when to boost a Facebook post using the acronym S.T.I.R. It assesses the post's shelf-life, the time since publication, its impact based on engagement, and the results measured by engagement rate. If four criteria are met affirmatively, the recommendation is to promote the post.

1. When do you STIR a
Facebook post?
S Shelf-Life - Will the post still be relevant 4 days from publication?
T Time - Has it been at least 6 hours since publication?
I Impact - Does the post include a link or other call-to-action that
creates desirable customer behaviors (beyond a simple “like”)?
R Results - Has the post exceeded a 1% engagement rate
(likes + comments + shares, divided by total fans)?
