Performance Max is a new, artificial intelligence driven ad format that runs your ads across all Google inventory.
Performance Max assets can be run on:
- Google Search
- Google Display
- Google Shopping
- Gmail
- YouTube
It has replaced Shopping campaigns, so in addition to the below, we recommend a shopping feed using Google Merchant Center to get the most out of your Performance Max campaigns.
Text assets
- Headline - 30 characters max; include at least one with 15 characters or less. Minimum 3, maximum 5.
- Long headline - 90 characters max. Minimum 1, maximum 5.
- Description - 90 characters max; include at least one with 60 characters or less. Minimum 2, maximum 5.
- Business name - 25 characters max. One only.
Image assets
Marketing images
With your image assets, note that there is a maximum of 20 images that can be uploaded, but this is a shared maximum across landscape, square and portrait. In our experience, having variety of sizes gets you better results across the full Google inventory, e.g. 6 landscape, 6 square and 6 portrait.
- Landscape marketing image - Landscape (1.91:1) 1200 x 628 recommended; 600 x 314 min; 5120KB max file size. Minimum 1, maximum 20.
- Square marketing image - (1:1) 1200 x 1200 recommended; 300 x 300 min; 5120KB max file size. Minimum 1, maximum 20.
- Portrait marketing image - (4:5) 960 x 1200 recommended; 480 x 600 min. Minimum 1, maximum 20.
Logos
In your Performance Max asset group, you must have at least one logo, which is square (1:1). You can add more than one square logo if you need to. Landscape logos are completely optional, however we recommend this for most brands.
- Logo - (1:1) 1200 x 1200 recommended; 128 x 128 min; 5120KB max file size. Minimum 1, maximum 5.
- Landscape logo - (4:1) 1200 x 300 recommended; 512 x 128 min; 5120KB max file size. Minimum 0, maximum 5.
Video assets
All videos to be used must be:
- Uploaded to YouTube as either a public or unlisted video.
- Horizontal, vertical or square is supported.
- More than 10 seconds in length.
You can have up to 5 videos, but this is not compulsory. If you need a video produced, we can help with video production.
