The specific asset requirements for a performance max campaign will depend on the specific goals and channels of the campaign. However, here are a few general types of assets that may be required for a performance max campaign:

1. Ad creatives: Depending on the channels you are using for your performance max campaign, you may need to create ad creatives such as banner ads, social media ads, or email marketing templates. These creatives should be visually appealing and compelling, and should clearly convey the value of your product or service.
2. Landing pages: A well-designed landing page is an important asset for any performance max campaign. The landing page should be optimized for conversions, with a clear call to action, social proof, and other elements that encourage users to take the desired action.
3. Lead generation forms: If your performance max campaign is focused on generating leads, you may need to create forms to capture user information. These forms should be easy to use and should only ask for the information that is necessary for your business.
4. Email marketing templates: If you are using email marketing as part of your performance max campaign, you’ll need to create email marketing templates that are visually appealing and effective at driving conversions.
5. Tracking and analytics tools: To track the performance of your performance max campaign, you’ll need to set up tracking and analytics tools such as Google Analytics or Mixpanel. These tools can provide valuable data on campaign performance and help you to identify areas for optimization.

Overall, the specific asset requirements for a performance max campaign will depend on the goals and channels of the campaign. By creating high-quality assets and using tracking and analytics tools, you can effectively manage your performance max campaign and drive strong results.
