How to write Facebook ad headlines that work

A Facebook ad headline works when it tells the reader, in a few words, what they get and why it matters to them. Meta ads have two headlines worth writing. The line on the image stops the scroll, and the headline field under the image reads like a caption and should carry the offer or the main benefit. Keep both short, specific and in the words your customers use, and do not repeat one in the other.

The formulas below cover most of the headlines that keep running in the Meta Ad Library. Draft variations with the hook generator at /tools/ad-hook-generator, check length and wording with the ad copy checker at /tools/ad-copy-checker, then test several against each other with the image held constant.

How to write a Facebook ad headline

  1. 1

    Write the ad's message in one sentence

    Before you write a headline, write the one thing the ad says as a plain sentence. The headlines are shorter versions of it.

  2. 2

    Write the image headline as the hook

    Name the reader, the problem or the result in the words a customer would use. This is the line people read first, so it goes in the largest type.

  3. 3

    Write the headline field as the takeaway

    Use the field under the image for the offer, the product name with its promise, or the strongest benefit.

  4. 4

    Write ten, keep three

    Draft at least ten versions using different formulas from this guide. Cut any that sound like an advert rather than a person.

  5. 5

    Cut every spare word

    Remove adjectives and brand language until nothing else can go without the line losing its meaning.

  6. 6

    Check it on a phone

    Preview the ad in Ads Manager on mobile placements to see where the headline gets cut off, and run it through /tools/ad-copy-checker.

  7. 7

    Test with everything else fixed

    Run three to five headlines against each other on the same image and offer, and judge them on cost per purchase or lead.

The two headlines in a Meta ad

The headline field is the bold line under the image, beside the call-to-action button. People read it after the image, as a caption, so it works best as the takeaway: the offer, the product with its promise, or the benefit in plain words. Some placements add a description line below it, which you can use for a guarantee or delivery detail.

The image headline is the text on the creative itself. People see it before anything else, so it does the stopping. It is usually a hook, such as a question, a call-out or a bold claim you can prove. The guide at /guides/facebook-ad-copy covers how the headline field works with the primary text above the ad.

Headline formulas, with examples

Replace the brackets with your own product and customer. The examples show the shape and are not claims about any real product.

  • Result without the pain. '[Result] without [the thing they dislike].' For example, 'Clean floors without dragging the hoover out.'

  • The offer. '[Offer] on [product].' For example, 'Free delivery on your first order.' Only use an offer you run.

  • The call-out. 'For [person] who [situation].' For example, 'For people who cook once for the whole week.'

  • The specific fact. A checkable detail instead of an adjective. For example, 'Three ingredients. Nothing else.'

  • The question. A question your reader answers yes to. For example, 'Still ironing shirts every Sunday night?'

  • The comparison. '[Your way] instead of [the usual way].' For example, 'One bottle instead of five.'

  • The objection answer. The doubt, answered before it is asked. For example, 'Yes, it fits in hand luggage.'

  • The proof. A short line from a real review, used with permission, with the customer's first name.

  • The deadline. Only when it is real. For example, 'Ends Sunday at midnight.'

How long a Facebook ad headline should be

Short enough to show in full on a phone, which usually means a handful of words. Meta's ads guide lists a recommended headline length for each placement, and longer headlines get cut off on some of them. Put the word that matters most at the start, so the line still works if the end disappears. The preview in Ads Manager shows where your headline breaks, and /tools/ad-copy-checker flags lines that run long.

Headlines that sound like a person

The best headline words come from your customers. Read your reviews, support emails and comments, and note the phrases people use to describe the problem and the result. 'Finally a lunch box that does not leak in my bag' beats 'leak-resistant food storage solution' because it is how a customer would say it.

Cut superlatives such as best, premium and revolutionary, which readers skip. Leave your brand name out of the opening unless people already know it. Mockingbird writes a voice profile from your website, listing words you use and words you never use, and every headline it writes follows that profile.

Headlines that get ads rejected

A headline can get an ad rejected on its own. The usual problems are wording that tells the reader they have a personal condition, claims you cannot prove, and deadlines or discounts that are not real. Unusual spellings or symbols used to dodge review cause trouble too. The guide at /guides/facebook-ad-rejected explains each problem and points to Meta's Advertising Standards.

Testing headlines

Hold the image, product and offer constant and change only the headline, so the result tells you something about the words. Run three to five at a time and judge on cost per purchase or lead, not likes. When one wins, write its next generation with the same formula, a sharper audience or a more specific result. The guides at /guides/meta-ad-hooks and /guides/ad-creative-testing cover hooks and test design in more depth.

To make headline variants of an ad you already have, type a note in Mockingbird such as 'Keep everything, change the headline to Free delivery on your first order' and get a new version. Each revision uses one credit.

Frequently asked questions

What is the headline in a Facebook ad?
The bold line under the image or video, next to the call-to-action button. It is separate from the primary text above the ad and from any text on the image itself.
How long should a Facebook ad headline be?
Short enough to show in full on a phone, which usually means a few words. Meta's ads guide lists recommended lengths by placement, and the preview in Ads Manager shows where yours gets cut off.
Should the headline repeat the text on the image?
No. Let the image carry the hook and use the headline field for the offer or main benefit, so the reader gets two pieces of information instead of one.
Can AI write Facebook ad headlines?
AI drafts variations quickly and helps with volume. The hook generator at /tools/ad-hook-generator gives you starting lines. Keep a person responsible for the final claim, because the advertiser is accountable for what the ad says.
How many headlines should I test at once?
Three to five at a time, on the same image and offer, judged on cost per purchase or lead.
