Common Grammar Mistakes Brands Make in Social Captions

Brand caption mistakes aren't random typos most of the time — a handful of specific errors show up across accounts again and again, often because the same habits (writing fast, editing on mobile, skipping a second read) produce the same kinds of slips.

"Your" vs. "you're"

Still the single most common brand-account error, and one of the most visible — it shows up in headlines, CTAs, and ad copy at a frequency that suggests autocorrect isn't catching it and nobody's reading the final copy out loud before publishing.

Inconsistent tense within one caption

Switching from past to present tense mid-caption — "we launched the feature and it's helping users save time, then we noticed..." — is subtle enough to slip past a fast read but noticeable enough to make copy feel sloppy on a careful one.

Comma splices in punchy, short-sentence copy

Short, punchy captions often join two complete sentences with just a comma instead of a period or conjunction. It's a minor grammatical issue that rarely confuses meaning, but it's exactly the kind of thing that undermines credibility on a brand account trying to look polished.

Apostrophes in plurals

"Check out our new product's" when referring to multiple products is a small, common slip that's easy to miss when reading quickly but stands out clearly to anyone who notices grammar — and on a brand account, someone always does.

The fix is a process change, not more carefulness

These errors persist not because people don't know the rules, but because there's no consistent second check before publishing. Building a grammar pass into the workflow — every time, not just when something feels off — catches what speed-writing reliably misses.
