Why Facebook and Instagram ad copy needs its own approach
Meta Ads (Facebook and Instagram) work differently from Google Ads: instead of matching search intent with a keyword, you're interrupting someone's feed and have a split second to earn attention with an image or video, then a few lines of text to close the interest. The primary text sits above the image, the headline sits just below it in bold, and the call-to-action button is the final nudge — all three need to work together, and all three have different length behaviour on the platform.
Why primary text length is flagged, not blocked
Unlike Google Ads' hard character limits, Meta doesn't reject a long primary text — it just truncates it behind a "See more" link in feed once it passes roughly 125 characters, and a lot of readers never tap "See more". The headline has a firmer 40-character limit before Meta itself may cut it off. This free Facebook and Instagram ad copy generator writes 3 complete combos — primary text, headline, and a suggested CTA button label like "Shop Now" or "Learn More" — from your offer and audience, and live-counts primary text and headline separately, flagging either in red if it's likely to get truncated.
Enter your offer or promotion and, optionally, who you're targeting, and you'll get 3 full combos to test against each other in Meta Ads Manager — each primary text, headline, and CTA suggestion copyable on its own so you can paste them straight into the matching ad fields.

Testing more than one combo
Meta Ads Manager lets you run multiple primary text and headline variations against the same creative and audience, and it will generally learn which combo performs best faster than manual guessing does. Rather than picking one combo and running it exclusively, it's worth loading all 3 generated combos into the same ad set as separate text options and letting delivery data decide — the winner is often not the one that reads best to you personally. Keep an eye on the primary text length specifically: shorter primary text tends to perform better on mobile feed placements, where the "See more" truncation point matters most.
