How are the products selected for Dynamic Ads creatives?
Facebook uses multiple types of signals to choose products from your catalog that it predicts generate the best outcome for you based on the optimization goal you have chosen. These are called product recommendations.
Facebook lists examples of factors that influence recommendations:
The products a person viewed on your website or in your app
The popular products in your catalog
Products your audience or people similar to them interacted with on Facebook and around the web
The same logic applies regardless of the way the audience has been defined, i.e., in both retargeting and Broad Audience campaigns.
It's not possible to control the product recommendations but you can define limits for promoted products with product sets.
What if there is not enough data to make recommendations based on related products?
The recommendation will fallback to select best sellers from the categories, in this example, the best selling pair of shoes as the third product if there is not enough data for better recommendations.
What product are feed formats supported in Smartly.io?
Supported formats in Smartly.io are XML/Google XML, JSON and CSV/TSV.
What happens if I use a Carousel ad and the user has only viewed one product?
Facebook will choose more products to show from the feed you choose and filter them for that specific campaign. The product recommendations might be from multiple categories if your Dynamic Ads campaign is not filtered down to one category only.
Why is the feed audience size 20?
The feed audience is created based on the pixel in the website, and it will start gathering once the campaign is live. Building the audience can take up to 24 hours. If the audience does not start to update, please make sure that you have made the required changes to your WCA pixel → Required changes to WCA pixel. Also, make sure that the pixel id matches the one in the account settings.
What is the maximum file size of a feed file?
Maximum size of the feed file Smartly.io will send to facebook is 32GB. However, as a general rule - a recommendation from Facebook and Smartly.io for faster processing is to keep the feeds as small as possible while keeping the catalog as large as possible.
Technical limits are listed at the Facebook Advertiser Help Center.
Can I use multiple feeds in a single Catalog?
Yes, see "Adding multiple product feeds" in Catalog Setup.We recommend doing this.
Is it possible to create multiple campaigns from the same feed?
Yes. You can also use multiple audiences within the same campaign. Keep duplicate targeting in mind, though--there's no sense in retargeting the same product in many campaigns.
Do I need to change anything in Business Manager?
The Facebook account connected with Smartly.io must have admin rights in Business Manager. Only users with admin rights are allowed to create product catalogs in Business Manager.
Do I need to modify my Facebook pixel or SDK?
Yes. You should at least add ViewContent, AddToCart and Purchase events to be fired with parameters content_id and content_type and their values sent.
Can I use a Facebook pixel that has been shared from another account?
If possible, we recommend using the Facebook pixel of the account you are using. If you still want to use a shared pixel, you can set up the pixel ID of a shared pixel to override the account's pixel. This can be done in Settings > Pixels. The pixel needs to be first shared in Business Manager. More information here.
What should I write to the content_ids parameter to get the product ID filled there?
The product ID must be added there programmatically because it is different on every product page. The product id needs to be a string or an array of strings from the dataLayer of your website. The id needs to match the id column in the product feed to match the products. If you are not sure how to do this, please consult your IT resources and connect them with Smartly.io if needed. More information here.
What will happen to my retargeting audience if:
... I create a new Dynamic Ads campaign using the same catalog?
The retargeting audience is catalog specific. As long as you are using the same catalog to create the new Dynamic Ads campaign the audience will be the same.
... I change the product set used in my ad set?
The ad set audience will reflect the product audience collected to that product set previously. Note that the backfill might take up to 24 hours to happen.
... I create a new product set?
The product audience is backfilled based on event history as long as the products in the new product set have been in any product set in the catalog when the Pixel or App SDK events have fired. Note that this might take up to 24 hours to happen.
... I edit the creative template or add a new creative?
No changes will occur with the audience. Templates can be edited and created flexibly.
... I pause the Dynamic Ads campaign?
This will not affect the audience. The catalog will still gather the audience, and it updates as well.
How does audience prefill work in Dynamic Ads campaigns?
Audience prefill in Dynamic Ads campaigns is catalog specific. Audience will start to gather from the moment you create the catalog. The only requirement is that when a Facebook Pixel or App SDK event happens, it is recorded to a catalog only if Facebook's able to match it to a product belonging to at least one product set in the catalog.
Can I exclude users targeted with Dynamic Ads from other campaigns?
Yes. The recommended method is to create regular Website Custom Audiences (WCA) that represent the same group of customers you are targeting with the Dynamic Ads campaign. That WCA can then be excluded from all the other campaigns.
How do the Dynamic Ads audience exclusion rules work?
A person triggering a type of event configured in the exclusion rules will be excluded from targeting if the event happens for the same product (or product group) featured in the event that included the user in the audience.
Example based on Facebook's documentation:
Product audience is set to include ViewContent and exclude Purchase events. A person views product A and B and purchases product B. Unless A and B are variants of the same product group, the person will continue to remain in the audience because there's still a ViewContent event for product A.
Is it possible to use tracking links for Dynamic Ad campaigns?
Yes, but you'll need to ask your account manager to allow this feature for you. Then you can replace the product link in your Dynamic ads with the click tracking URL. Please use #PRODUCT_URL# to refer to the product link in the tracking URL. Example; www.trackingcompany.com/12345/tracking/#PRODUCT_URL#. More information here.
Will dynamic posts get comments?
In short, yes. People can also like and comment dynamic posts and thus they will also be seen by the users' friends (therefore they can get social impressions).
How can I verify that my mobile app events work with DPA?
How does the App Deep Link Behavior work?
Note: If you are using Product Sales as your campaign objective, to correctly verify your App Deep Link Behavior if you are always sending mobile users to app store instead of your mobile website if they don't have the app installed, you need to preview the ad in Ads Manager by choosing the option: View on Facebook: Facebook Mobile Newsfeed. All other previews handle this applink fallback behavior differently and will redirect to the mobile website instead so this is the only way to verify correct behavior. To get to this preview quickly, click on the ad in Smartly.io and choose "View ad in Ads Manager" and you will be taken directly to the correct ad in Ads Manager.
For App Deep Link Behavior, you have three options:
- Always send the user to the given web URL
- Launch app if it's Installed, otherwise, use web link
- Launch app if it's installed, otherwise, direct to app store
Always send the user to the given web URL
With this option, even if the users have the app installed, they will always be sent to your website URL defined in the feed.
For this option to work, you will need to define your deep links in the feed configuration or in the creative template under "Use custom App Deep Links". You will need to define the links separately for Android and iOS devices. Note that if you enter anything under "Use custom App Deep Links", this will override any deeplinks you have configured in the feed.
Launch app if it's installed, otherwise direct to app store
For this option to work, it is recommended you send the following information in your feed and map it to your catalog: iOS URL, iOS app store ID, iOS app name, Android URL, Android app name, and Android package. This is especially the case if you are using Product Sales as your campaign objective. For app install campaigns, feed mapping might not be required. In addition to mapping the behavior in your feed, you can also use custom App Deep Links.
You can see the instructions in the beginning of this question on how to correctly verify that this behavior works.
Are location-based parameters such as
shipping considered in Facebook's product recommendation engine?
Why are my images or Image Templates shown in a weird way?
On what level Facebook stores the learnings about user-product interactions?
At the point when a Pixel or App event fires, there needs to be a product with a matching ID that belongs to at least one product set. If that's the case, the learnings are stored in the Catalog for that product.
This data is used to build Dynamic Ads audiences (retargeting and prospecting) and to choose the best products to show for each user.
