The four jobs of a post

Every post that is worth publishing does at least one of four things. A post that does none of them was published because the page had been quiet, which is the most common reason bad content exists.

The four jobs are getting attention, keeping attention, building trust, and asking for action. They are sequential in effect and not in every post: a single post rarely does all four well, and one that tries usually does none.

Getting attention is the first three seconds or the first line. It competes with everything else on the screen. "Your office meeting does not need another plate of dry biscuits" earns a second of consideration. "BrightBite Snacks is a leading snack provider" does not.

Keeping attention is what happens after the opening has worked. Showing the snacks being weighed, arranged and boxed holds a viewer because something is progressing. A static photograph with four paragraphs under it usually does not.

Building trust is proof rather than claim. A photograph of the kitchen, a customer's message shown with permission, the same box delivered to a named event. Trust is the job most often skipped, and the reason accounts with good content still receive no orders.

Asking for action is the instruction. Send a message, save this, order by Thursday, comment with your choice. One instruction. A post asking for five actions receives none.

The strongest evidence for the four jobs is a study of 106,316 Facebook messages posted by 782 companies, published in Management Science by Lee, Hosanagar and Nair in 2018. Its central finding is more precise than the usual advice to sell less. Directly informative content, meaning price, availability and deal information, was associated with lower engagement when it appeared on its own, and with higher engagement when it appeared combined with brand personality content. The sales post is not the problem. The unaccompanied sales post is.

That result matters because it explains why an account can look disciplined and produce nothing. A manager who has been told to reduce selling often responds by publishing fewer sales posts of exactly the same kind, when the correction is to stop publishing them naked.

The trust job has independent support. Edelman's 2026 Trust Barometer brand report, based on 17,688 respondents across fifteen countries, found 88 per cent naming trust in the brand an important or critical purchase criterion, against 89 per cent for quality and 88 per cent for value. Trust is not a soft consideration sitting behind the hard ones. It is priced alongside them.

One older figure is worth knowing and dating carefully. Sprout Social's 2016 index found 46 per cent of people unfollow a business over too many promotional messages. It is genuine primary research with a disclosed method, and it is ten years old, so treat it as a direction rather than a current number.
