2. When should you run Carousel Ads?
Here are the golden times for businesses to take advantage of the strengths of carousel ads:
2.1 When businesses want to advertise multiple products
Carousel Ads will help businesses save maximum costs when they want to advertise multiple products at the same time, usually products with the same characteristics. Each product is located in a card, including a link to the landing page of that product. This helps customers have more choices, increasing the click rate for the website.
2.2 When a business wants to introduce a product in detail
Businesses use carousel ads when they want customers to understand more about their products. Each business card will show details of the parts or special aspects of that product.
2.3 When businesses want to attract user interaction
A long, engaging story of the business will attract users to swipe to see more, increasing their level of interaction on the ad.
2.4 When businesses want to explain the process
Businesses increase customer trust and attract more interaction through step-by-step images/videos to produce or use that product/service.
3. Why should businesses run Carousel Ads?

3.1 Carousel ads are more attractive than single image/video ads
Multi-product ads will attract customers’ attention more than regular ads. Businesses can introduce multiple products and services in one ad. Carousel Ads can display 10 products with product descriptions, prices, and CTAs to help customers make decisions and make purchases more easily.
The goal of marketers is to find ways to attract users’ interest and attention. Through Carousel Ads, this goal is easier to achieve. The rotating ad templates are user-friendly but do not overwhelm the ad or confuse buyers. The quality of advertising is improved, highlighting the attractiveness of the product through images and videos with attractive content.
3.2 Cost-effectiveness of Carousel Ads
Many people still mistakenly think that advertising multiple products with Carousel Ads will cost more. However, in reality, the cost of carousel advertising is only at a low average level. The cost per click (CPC) for Carousel Ads is lower than that of conventional single image advertising.
Not only that, carousel ads on Facebook are displayed strategically, effectively but not wastefully. If you have a small advertising budget, Carousel Ads is the ideal choice.
The cost of carousel advertising depends on many factors such as target audience, content, ad display time, etc.
3.3 Flexible carousel advertising
Thanks to Facebook’s detailed reports, businesses can track whether the advertising link is effective or not. Then, let Facebook optimize those links for higher ad engagement.
Carousel ads allow you to integrate 10 call-to-action buttons for 10 images. This means you can diversify your calls to action to visit your website, download your app, or participate in promotions and newsletters.
