A caption is a small essay

The snobbery about social media copy is that it is not writing. It is, and it is some of the least forgiving writing you can do.

A caption has a word or two before the fold, a reader who did not come for prose, and a scroll velocity measured in milliseconds. It has to earn the tap the way the first line of a short story has to earn the second. Everything I learned about openings from literature applies here, only with the stakes moved up and the runway cut to nothing.

The good ones work like tiny essays. They have a turn in them, a small betrayal of the expectation the first line set up. They know the difference between a hook and a trick. A hook keeps a promise the rest of the caption pays off. A trick just spends the reader’s tap and teaches them not to trust you next time. Do that often enough and the algorithm is the least of your problems. People stop reading you.

I hold captions to the read-aloud test, same as anything else. If it sounds like a brand talking, I have failed. Brands do not talk. People talk, and occasionally a person is talking on behalf of a brand, and the whole craft is hiding the seam between those two things so well that it disappears.

You can learn more about compression from writing a good caption than from a term of poetry. Poetry lets you be difficult. A caption has to be immediate and still have a second floor, a meaning that opens up a beat after the first read. Immediate and deep, in under thirty words, against the clock. Tell me that is not writing.
