The first slide of your carousel: how to write the hook
By Pedro Lima
Slide 1 doesn't sell the product — it sells slide 2. Five hook formats that work, and the mistake that kills a great carousel on the cover.
Slide 1 has one job: the swipe
The cover of a carousel doesn't have to explain the topic, convince anyone or introduce you. It has one job: get the thumb to swipe sideways instead of scrolling down.
That changes what you write. A cover that summarizes the whole post hands over the answer and makes the rest optional — people read it, agree, and keep scrolling. A cover that opens a question in their head forces the second slide.
Five formats that work
None of them is a trick: all five work because they leave something open.
- Number plus consequence — “7 mistakes that make your website lose sales”. The number promises size, the consequence gives a reason.
- Contradiction — “Posting every day is holding you back”. It goes against what the reader believes, and they want to know why.
- Before and after — “From 40 to 4,000 followers without ads”. The jump is the question.
- A mistake they're making — “You're using hashtags wrong”. A light accusation, addressed to them, with a fix promised.
- A question they can't answer — “What does one customer cost you?”. If they don't know, they swipe.
Write the hook AFTER the content
A cover written first turns into a promise the content can't keep — and a carousel that promises more than it delivers is worse than a weak one, because it burns the trust of everyone who swiped.
Write the middle cards, find the best sentence that showed up in there, and promote it to the cover. More often than not, the best hook was already sitting on slide 4.
Legibility is part of the hook
A hook you can't read in half a second isn't a hook. The feed is scrolled fast, phone in hand, often in sunlight.
- Few words, big. If it needs three lines, it's probably two ideas.
- High contrast between text and background. A nice photo with gray text over it is the most common way to lose a cover.
- One idea only. The cover isn't the place for a subtitle, a logo, a handle and a call to action all at once.
The mistake that kills good carousels
Leaving the cover for last and treating it as decoration — picking a photo because it looks nice and dropping the post title on top of it.
The cover is the only slide everyone sees. The other nineteen depend on it. If time is short, that's where it should go.
Frequently asked questions
What should I write on the first slide of a carousel?
A short line that leaves a question open — a number with a consequence, a contradiction, a before and after, a common mistake or a hard question. The cover sells the second slide, not the whole topic.
Should the hook include a hashtag or a handle?
No. The cover has a single job, and every extra element splits the attention it needs to earn the swipe. Hashtags live in the caption.
