How it is calculated
Not a metric — a production requirement

Why captions matters

Most paid social is watched on mute. An ad that does not work silently does not work.

Worked example

What this looks like with real numbers

Watch your best ad with the sound off. If you cannot tell what is being sold in the first three seconds, most of the people you are paying for cannot either, and they will not turn the sound on to find out.

What it does not tell you

Platforms describe captions as recommended rather than required, which reads as optional and is not. Burned-in captions also survive the platform's own caption toggle being off.

The mistake people actually make

Relying on the platform's auto-captions. The viewer can switch them off, they mis-hear product names, and they ignore your safe zone entirely.
