For modern paid media advertisers, Google Performance Max campaigns are highly effective for driving e-commerce sales and B2B leads across Search, YouTube, Display, and Discover. However, because Performance Max is heavily automated, the success of your campaigns depends on the quality of the assets you provide. If you upload thin copywriting or low-resolution images, Google's algorithms will deliver poor-performing ads. Implementing a structured **Google Performance Max asset groups checklist** is key to maintaining ad quality scores and scaling ROAS.
What is an Asset Group in Performance Max?
An Asset Group is a collection of creative assets (images, videos, logos, headlines, descriptions, and audience signals) used by Google to compile ad variations dynamically based on the target viewer's channel and context.
The Performance Max Creative Checklist
1. Copywriting Variations (Headlines & Descriptions)
- Provide 5 distinct Short Headlines (30 character limit). Test discount offers, benefit statements, and brand name hooks.
- Provide 5 Long Headlines (90 character limit). Write comprehensive value propositions (e.g., "India's Leading AI Marketing Consulting Partner").
- Provide 5 Descriptions (test short hooks and long-form features).
2. High-Resolution Visual Assets
- Upload up to 20 Images (minimum requirements: landscape 1.91:1, square 1:1, and portrait 4:5).
- Ensure images are clean and contain no prominent text overlays, which can block Google layout rendering.
- Upload up to 5 Videos (minimum 10 seconds length). If you fail to upload custom videos, Google will dynamically compile low-quality slide-shows of your images, hurting brand authority.
- Add Audience Signals to help Google's algorithm find buyers faster: custom search intent, customer matches, and website segments.
