Captions need a legal pass

Prices, results, "best", health outcomes, and competitor comparisons are not caption flavor. They are statements the client may have to defend. Someone who knows the rules has to read them. That someone is not always the designer.

If you do not have a lawyer in the loop, you still need a named person at the client who accepts the claim. Write their yes next to the sentence, not as a general "approved the post."

If the caption says a number, write where the number came from. A deck from last year is a common source and a common mistake. The approver should see the source without hunting email.

When the source is "the founder said so on a call," treat it as unverified until it is written down. Calls feel authoritative and then vanish.

Alt text, on-image type, and thumbnail titles repeat claims in places people forget to check. A careful caption with a reckless sticker is still a reckless post.

Read the image as a sentence. If the picture promises a result the caption carefully avoids, the picture wins in the reader's memory.

Before lock: offer matches the live page, dates are real, required disclosures are present, and tags are allowed. Four lines. Print them in the review step so they are not a speech you give when something already went wrong.

Update the list when a client has a special rule, such as no before-and-after or no user quotes without a release. Special rules that live in a kickoff doc will be missed by month two.
