What Types of Assets Can Be Used in Performance Max Campaigns?

Google recommends providing as many high-quality, diverse assets as possible. The more assets provided, the better the system can optimize for performance.

How Many Assets Should Be Provided for Optimal Performance?

While it's not mandatory to provide both, having a mix of images and videos allows your ads to appear in more types of placements and can enhance performance. Keep in mind that if you don't provide video assets, Google Ads will use your images to produce auto-generated video animations for your campaign.

Is It Necessary to Provide Both Images and Videos?

Google's machine learning algorithms mix and match these assets to create ads tailored to various audiences and contexts across Google's advertising networks.

How Does Google Use These Assets?

No, you cannot control exactly where each asset will appear. Google's algorithm decides the best combination and placement of assets for each ad instance.

Can I Specify Where Each Asset Appears?

Performance Max campaigns continuously test different asset combinations and placements, learning over time which performs best in terms of your campaign goals.

How Does Google Determine the Best Performing Assets?

Yes, you can use dynamic feeds, such as a product feed in a Performance Max campaign.

Can I Use Dynamic Feeds with Performance Max?

No, Google Ads does not provide performance metrics at the asset level. You will be able to get performance data at the campaign and asset group level.

Can I Get Detailed Performance Data on Individual Assets?
