What are Meta's ad copy character limits?

Meta recommends primary text under about 125 characters before truncation, headlines under 40 characters, and link descriptions under 30 characters. This builder shows live counts for the headline and description so you stay within them.

Why generate three primary-text angles?

Meta's algorithm optimizes best when you give it variations to test. The builder produces a problem-solution angle, a benefit-led angle, and a social-proof or urgency angle so you can run an A/B test from one set of inputs.

Which CTA button should I choose?

Match the button to the action: Shop Now for ecommerce, Sign Up or Subscribe for lead gen, Book Now for services. The builder offers the standard Meta CTA set so your choice maps to a real button.

Will this copy comply with Meta's ad policies?

The templates avoid prohibited claims, but you are responsible for policy compliance. Review Meta's advertising standards, especially for health, finance, and before-and-after claims, before launching.

Can I edit the generated copy?

Yes. The output is a starting point built from your inputs. Copy it, then tweak wording, add your brand voice, and shorten anything that runs long before pasting into Ads Manager.

Three ad angles from one set of inputs

A Meta ad needs primary text, a headline, a link description, and a CTA button — and the campaigns that win are the ones that test multiple angles. This builder takes your product, audience, benefit, and offer and produces all four fields plus three distinct primary-text variants ready for an A/B test.

How it works

The tool generates three primary-text variants using proven direct-response angles: a problem-solution opener that names a pain point, a benefit-led version that states the outcome first, and a social-proof or urgency version that adds credibility and a reason to act now. Your stated benefit is capitalized and trimmed to Meta’s 40-character headline limit, and your offer (or a fallback) is trimmed to the 30-character link-description limit, both shown with live counters. The CTA dropdown maps directly to Meta’s real button set so the copy you build matches the buttons available in Ads Manager.

Tips and example

Phrase the benefit as the reader’s outcome — save 10 hours a week beats time-saving software.
Keep your audience specific (busy parents, B2B founders); generic audiences produce generic copy.
Run all three angles as separate ads in one ad set and let Meta find the winner, then iterate on it.
Always sanity-check the auto-trimmed headline and description — a hard cut at 40 characters can read awkwardly, so reword if needed.
