How to use the facebook ad preview

1 Type your title and description. The preview updates as you type.

2 Watch the character counts — they turn red past the limit, and the preview shows where the cut lands.

3 Drop an image in to see the whole card.

The 125-character fold is the number that matters, because everything after it requires a tap that most people do not make. Put the offer and the hook before it and treat the rest as detail for the interested. The headline at 40 characters is the second-most-read element and works best as a plain statement of what the thing is rather than as a second slogan. Note that the old rule against images with more than 20 percent text is no longer enforced as a rejection — Meta dropped it — but text-heavy images still measurably underperform in the auction.
