Ad copy

Ad copy is the written text of an ad: the words that explain the offer and persuade people to act. In Meta ads, it is the primary text, the headline and any text on the image or video, together with the call to action that closes it.

The parts of ad copy on Meta

Part What it does What to put in it
Primary text Carries the argument Who the ad is for, the problem, the offer
Headline Gives the one-line takeaway beside the button The main benefit or the offer itself
Text on the creative Works even when the caption is skipped A short line, kept clear of the edges of the placement
Call to action Names the next step One action that matches the landing page

Ad copy is not the same as the ad creative. The creative is the image or video, and the copy is what the words add to it. Each does a different job, as the answer on ad creative vs ad copy explains.

How placement changes the copy

The same ad appears in Feeds, Stories and Reels, and each lays the text out differently. Meta's tips for text in ads suggest tailoring copy by placement, such as shorter copy for Stories. In a tall placement the words sit over the media, so a long line can cover the product. In Feed, long primary text is cut off behind "See more", so the first lines have to carry the point.

How to write ad copy that works

  1. Start with one reader. Write to a single person with a single problem, not "everyone who might like coffee".
  2. Open with the hook. The first line decides whether anyone reads the second.
  3. Say what changes for them. Lead with the result the buyer gets, then the feature that delivers it.
  4. Add proof. A real review, a number you can back up or a named customer works as social proof.
  5. End with one action. Ask for one thing, and make the button agree with it.

Two frameworks help if you stall. Problem, agitate, solution names the pain, makes it vivid, then offers the fix. Before, after, bridge shows life without your product, life with it, and how to get there. Both are writing habits, not Meta rules.

How to tell whether copy works

Judge copy on what it buys, not on how it reads. Watch the click-through rate to see whether the words earn clicks, then the cost per result to see whether those clicks become customers. Copy that gets many clicks from the wrong people raises the click rate and the cost per result together.

To compare versions fairly, change one thing at a time and run them as an A/B test. If you rewrite the headline, the image and the offer together, you can't tell which change did the work. Meta advises against "testing informally, such as by turning ad sets or campaigns on and off manually".

Common mistakes:

  • Writing for the advertiser ("We are proud to announce") instead of the buyer.
  • Stuffing several offers and several actions into one ad.
  • Promising what the landing page doesn't show.
  • Copying a competitor's line, which makes your ad sound like theirs.

Example. A coffee subscription brand tests two versions of an ad for its starter box, each with a $400 budget. Version A opens with "Fresh roasted coffee, delivered monthly" and brings 16 purchases, so each costs $25. Version B opens with "Tired of stale supermarket coffee? Get beans roasted within a week of shipping" and brings 20 purchases, so each costs $20. The brand keeps B and writes the next test around its "stale coffee" angle.

FAQ

What is ad copy in Facebook ads?

It is the text of the ad: the primary text above the media, the headline beside the button and any words on the image or video. Together with the button, it tells people what you offer and what to do next.

How long should Facebook ad copy be?

As long as it takes to make the case, and no longer. Put the main point in the first lines, because long primary text is cut off behind "See more", and shorten it for placements like Stories.

What is the difference between ad copy and ad creative?

Ad creative is the image or video people see, and ad copy is the written text. The creative stops the scroll, and the copy explains the offer. Both need to agree.

Can AI write Meta ad copy?

Yes, AI can draft several versions quickly, and that speeds up testing. A person still needs to check the claims, the tone and the fit with the offer before the ad runs. The answer on whether AI can write Meta ad copy goes through what to check.
