Facebook Carousel Ads: The Complete Guide For Better Results with Ads

by Gabi Barbosa

There’s been a lot of talk lately about Facebook launching a new type of ad: the carousel ad. You might have seen them around your news feed.

Facebook is rolling it out now across its ad accounts – on Power Editor - starting in the United States, but if you are a Driftrocker, you got early access to them last month on our new Ads creation tool Create. If you don’t have access to them yet, or dislike Power Editor, you can request a demo of Create to get started with these ads.

As with any new type of ad there's a lot of uncharted territory, but we've been using them since end of last year so we thought we'd share some of the things we've seen and learned along the way!

What are multi product ads?

Facebook multi product ads are a new type of Facebook ad format that enables advertisers to display 3 (to 5) products or images within a single ad unit. Each product or image has its description and link that takes people to a landing page.

Here’s what they look like (ad examples from Facebook):

It is only available for the news feed, both on mobile and desktop. Mobile users can swipe to their hearts’ content, while desktop users can move between images by clicking on the left or right arrows.

Pro tip: Facebook is working on a feature to automatically optimise the images in your multi product ads. You just upload a bunch of features and Facebook will automatically choose the best ones to feature on the ad, based on performance.


What are the ad specifications?

Here is what are the recommended design specs, for the ads to be properly shown on all devices (and to no be disapproved):

  • The images should be 600 x 600 pixels at least (square)
  • Post/Ad text should be around 90 characters
  • Link headline should be around 25 characters
  • Description for each image/product should be 30 characters

And of course, the image cannot contain more than 20% text, or Facebook will not approve/disapprove it. You can use Facebook's grid tool to see how much text your images have.

There’s a lot of things you can do with this type of ad unit, and we’ll get to that in a second. First, let’s address the first question that’s probably going through your mind:


How much do they cost?

Multi product ads have a lot of different places for people to click, so when we first saw them we got all sorts of worries about ad spend and budgets and costs per click BUT Facebook has thought this through.

You pay for them like any other ad. CPM, optimised CPM or CPC.

If you are optimising your bids/paying for clicks (CPC), Facebook should only charge you once in the first 30 seconds that the ad is displayed. However, after those 30 seconds every click counts as an additional click.
So if someone sees your ad and clicks 3 times in the first 30 seconds, you should get charged for 1 click. But if they click 4 more times after those 30 seconds, you will be charged for 5 clicks in total.


What are the different uses for multi product ads?

Everyone has been talking a lot about multi product ads being great for ecommerce, but most other types of business can also get fantastic results from them. Here are a few examples of how they've been used:

Showcasing multiple products/tools: Driftrock Multi product ad

Yes, we started creating multi product ads as soon as we could get our hands on them. Since Driftrock is a platform with multiple tools, we used the ads to showcase each of the tools in our platform.



Displaying different features of a service: Transferwise multi product ad

in another example, Transferwise use multi product ads to show the different features of their money transfer service (to different countries).



Displaying multiple offers: Sky multi product ad

Sky used multi product ads to give their audience some additional insight into their special Christmas offer they were running.



Showcasing multiple images/parts of a product Alt text

Auto Offers used multi product ads to display the rich images of a product. If you've got it (it being bright imagery), flaunt it!



Communicating several benefits of a product or service: Alt text

The good ol' killing two birds with one stone. This is probably not best practice, but we used multi product ads in a campaign to promote our automated Facebook Custom Audiences tool Flow. Instead of showcasing just 3 benefits, we decided to go with 2 images showing benefits and one with a 'View Product Demo' call to action, for people who were interested in finding out how the tool worked.

Feel free to share any other uses you've seen or tried out, in the comments below!


Do Facebook multi product ads actually perform better?

Another question that comes up quite frequently is how much better multi product ads actually are, when compared to regular page post ads.

We've tried it a bunch of different times, and so have our clients (with Create!) and there's no escaping it:

Significant increase in engagement and clickthrough rate (up to 50% higher in some cases), decrease in cost per click - 46% lower in some cases.

If increased engagement and clickthrough rate are sustained or not, it is too early to tell. It might be that this is happening because the ad format is new and people are curious, but it is unlikely that this is the only reason. Either way, higher engagement improves your Facebook ad quality score, which reduces your costs, so you benefit either way.

Pro tip: Keep a close eye on the post click website conversion rates from multi product ads and compare them to your page post ad website conversion rate, if that's important for you (and it should be!). We've found that multi product ads post click conversion rates can vary quite a lot between verticals, and are not always as good as the CRs you get with page post ads.



However, whichever your business or industry, you cannot afford to be missing out on multi product ads! Why not get right on it with our Facebook ads creation tool Create?
