How Auto Placement Asset Customization works

We’re excited to announce the launch of a new feature in our Creative Testing tool that automatically assigns creatives to the correct placements. Simply select creatives that include a placement tag in their name, and the system will automatically map them to the appropriate placements—Feeds; Stories & Reels; Apps & Sites; Search Results; and Instant Articles.

Multiple placements increase the number of people who can see your ad and can improve ad results. This not only increases your ad's visibility but also enables you to reach potential customers at different stages of the customer journey.

Whether you build new creative sets under Launch - Creative Testing or on the fly when setting up a new Creative Testing campaign, you can use Auto Placement Asset Customization.

1) First, before selecting your media, toggle on setting "Auto-assign media to the placements":

If this setting enabled, media files with placement tags in their names will be automatically matched to the right placements and grouped into single ads.
​

To assign the right creative to the right placement, we use naming tags in your file names:

– One tag groups creatives into a single ad

– Another tag assigns them to specific placements

Configure the tags below to match your internal naming logic:

Feeds: _feeds

Stories and Reels, Apps, Sites: _stories

Search results, Instant Articles: _search

Example: summer_sale_feed and summer_sale_stories will be grouped into one ad and shown in Feed and Stories respectively.

2) Go to the Media section of the creative set and choose an Image/Video/Slideshow that you want to use for this set. We will auto-assign creatives right after you confirm selection in the Media Library with the “Add N files” button.

​

3) If you need to customize creatives even if the "Auto - assign media to the placement" feature is enabled, it is possible. Once you uploaded the creatives, please click on the ▲ sign on the right side to unfold the options for each placement:

Next to each option, you will see the name of the file and its dimensions. These parameters reflect the parameters of the file you uploaded, as all three options are filled with a selected creative automatically. If you do not want to customize the creatives for a specific placement, leave it as it is, but bear in mind that Meta might crop your image to fit each placement.

4) If you would like to change the creative so that it fits the ratio required for the feeds/ stories etc, please hover over the placement that you want to customize the creative for, and click Change Image/video button that appears on the right side:

Once you click Change, the media library window will pop up, please select the file that you want to be used for this placement, and hit Add image/ video. You will notice that the creative in the chosen placement has been changed, and the dimensions of the customised image are displayed:

5) If you would like to revert the file back to the original, please hover over the placement again and click the Clear customizations button on the right side. If you do this, the placement will use the creative that you uploaded initially.

Whether you choose to customize your creative for a specific placement or not, you can always preview what the ad will look like in any placement with the selected creative and other variables (text, URL, CTA, etc) on the right side. Use the placement selector on the top right corner to see all the options:

Now, if you choose specific placements manually in your Creative Testing template or go for Automatic placement, you can be sure that Meta will use the creative that you customized for each placement:
