LinkedIn Carousel Ads

A LinkedIn Carousel ad is a Sponsored Content unit that holds a row of swipeable cards in the feed. LinkedIn's ad guide lists 2 to 10 cards, a recommended size of 1080 by 1080 pixels, JPG or PNG files, and a maximum of 10 MB per file. Each card has its own image and can link to its own destination, so a single ad can point to several pages. You pick the Carousel format in Campaign Manager, upload the cards in order, write the intro text, and add a headline for each card. The ad is published through a company page and appears between organic posts. Think of the card sequence as a mini story with a beginning, a middle, and a next step.

The mechanism is simple: a member sees the first card and decides whether to swipe. Everything after card one depends on that decision, so the first card carries most of the weight. From there the reader moves card by card, and you can use the sequence to build an argument, show steps in a process, list services, or present several customers. Because each card can link to a different page, the format lets you test which topic draws clicks. The intro text above the cards appears with every card, so it should work as a standalone headline for the whole ad rather than a lead-in to card one only. Each card should make sense on its own, since some readers will stop after the first.

Carousel works with the same audiences, objectives, and bidding options as other Sponsored Content, so it competes with Single Image and Video ads for the same people. Compared with a Single Image ad, it carries more information, and compared with a Document ad, it is lighter and the cards link out individually. It does not gate content on its own, so lead capture happens at the destination or with a Lead Gen Form attached to the ad. The number of cards is a creative choice, not a setting that improves delivery. Two or three strong cards can outperform ten weak ones. Keep the visual style consistent across cards, with the same fonts and colors, so the unit reads as one ad.

The usual mistake is spreading one idea across cards that nobody reaches. Most members see card one and perhaps card two, so a punchline on card eight is wasted. Put the strongest proof or the clearest promise on card one and treat the later cards as depth. A second mistake is using a card per feature with no story, which reads like a catalog. A third is inconsistent design, where cards look like they belong to different ads. Also check that each destination matches its card, since a click on a pricing card that opens a homepage loses the reader. Avoid using the carousel to hide weak content behind a swipe, because readers decide quickly whether to continue.

Build a three-card version first. Card one states the result you offer, card two shows the proof, such as a number or a customer, and card three gives the next step. Use consistent colors and large text that reads on a phone. Run it against a Single Image ad with the same audience, budget, and offer for two weeks. Compare click-through rate and cost per lead. If the carousel wins, expand to five cards and test whether the added cards help or just add scrolling. If it does not win, keep the best card as a single image. Look at card-level clicks where available, and rebuild the order if the later cards never get clicked.
