KI-Facebook-Werbetext-Generator

Facebook ad character limits in 2026

Primary text — 125 characters visible before 'see more'; up to 2,200 total. Headline — 27 characters before truncation in feed; up to 40 characters. Link description — 27 characters in feed; up to 30 characters.

The ratio: 80% of viewers read only the primary text first line, ~50% see the headline, ~20% see the link description. Front-load value in the primary text; treat headline + description as amplification.

Primary text formulas that convert

Four formulas that consistently lift CTR. (1) Problem + question — 'Spending hours on social posts? Here's the 15-minute fix.'. (2) Specific outcome promise — 'How [persona] hit [metric] in [time]'. (3) Curiosity gap — 'The 3 marketing mistakes costing you $10K/month'. (4) Story open — 'I tried 12 social media tools. This one cut my time in half.'

The generator outputs one variant per formula. A/B test which one fits your audience.

Headline + description: the supporting cast

Headlines amplify the primary text's promise. Not a restatement — a sharpener. If primary says 'cut hours from social', headline should say 'Save 10 hrs/week'. Specific numbers in the headline outperform generic ('Save Time') 2-3×.

Link description (the small text under the headline) is rarely read on mobile but visible on desktop. Use it for risk-reversal: 'Free 14-day trial. No credit card.'

The generator outputs headline + description matched to primary text by default.

Words that trigger Facebook ad rejection

Facebook auto-rejects ads with certain words/phrases. Common triggers in 2026: 'guaranteed weight loss', 'make money fast', 'free money', 'cure', 'miracle', 'crypto investment', 'mortgage' (without proper disclaimers), 'you' or 'your' addressing personal attributes ('Are you over 40?' — personal trait).

The generator avoids these by default. Still run final copy through Facebook's ad preview before launch — policy updates monthly.
