Photo Carousel Ads for Apps: What Works on TikTok

Photo carousels are the quiet overachievers of app advertising. There is no camera, no creator and no voiceover, just a few slides and a line of text. Here is how they’re built in the Adlist library, and how to make one for your app.

What a photo carousel ad is

A photo carousel is a post made of still images the viewer swipes through, usually with music under it. The first slide carries the hook, and each slide after it makes one point. On TikTok they sit in the same feed as videos, so they compete for the same three seconds.

Why apps run so many of them

Among the formats in the library, photo carousels rank second by median views, behind only animation, and ahead of UGC, screen recordings and talking-head ads. Views measure reach, not installs, so read that as a sign of what spreads, not what converts. They’re also cheap to make: you can build several versions in the time it takes to film one video.

Health and fitness apps account for 36% of the carousel ads in the library. Productivity and lifestyle apps come next, at 15% each. Anything with a before and after, a plan or a list of tips fits the format naturally.

The first slide does all the work

Carousels are the most text-driven format in the library. 98% show their hook as on-screen text, and 98% finish it within the first three seconds, against 72% across all formats. There is nothing else on the first slide to hold attention, so the line has to.

Carousel hooks are also shorter than most: a median of seven words, against nine across the library, and 87% use ten words or fewer. They use numbers more often too, in 19% of hooks against 15% overall, and questions less often, in 6% against 13%. A promise of a list reads faster than a question.

Listicles and before-and-afters lead

Listicles make up 43% of carousel ads in the library, far more than any other hook type. Before-and-after hooks come next at 11%, then tutorial, showcase and meme hooks. Of the two most common, before-and-after carousels have the higher median views. The format suits both: a list gives every slide a job, and a before-and-after gives the swipe a payoff.

Four carousel structures to try

Each one is a structure, not a script. The example lines are written for illustration, so swap in your own audience and app.

1. The numbered list. Slide one promises a count, each slide delivers one item, and the app is one of them, usually the last. For example: “5 apps that fixed my mornings.” It works with the listicle hook pattern.
2. The before and after. Slide one shows the starting point, the middle slides show the steps, and the last shows the result with the app in it. For example: “My budget in January vs my budget in June.” See more on the before-and-after hooks page.
3. The step-by-step. Each slide is one step of a task the app makes easy, with a screenshot of that step. For example: “How I plan a week of meals in 10 minutes.”
4. The relatable meme. A familiar caption format on slide one, a few slides that build the joke, and the app as the punchline. For example: “Things I say I’ll do vs things my habit app makes me do.”

How to build one, slide by slide

1. Write the first slide first: one line, about seven words, large enough to read without tapping.
2. Give every slide one point. If a slide needs a paragraph, split it or cut it.
3. Show the app as it really looks, with a clean screenshot on the slide where it solves the problem.
4. Keep it short. Carousel ads in the library run a median of 18 seconds, and only 9% go past 30.
5. End on the result or the app, not on a slide of features.
6. Make three versions with different first slides, and test them against each other.
