Performance Max for a fashion store: The New Black AI
Published 27 September 2026
Performance Max is Google's campaign that runs one set of pictures and texts across Search, YouTube, Display, Gmail and Discover. It works as well as what you feed it: empty asset slots and a single blurry product photo are where "PMax does not work" usually starts. In The New Black AI, a Performance Max campaign is launched from Store › Ads with your studio creations as the pictures, and the texts drafted by AI for you to edit.
What the form fills for Google
| Asset | Where it comes from |
|---|---|
| Landscape images (1.91:1) and square images | Your creations, cut to Google's shapes automatically |
| 3 to 5 headlines | Drafted by AI from your brand, the product and the landing page, editable |
| Long headline | Drafted by AI, editable |
| Descriptions | Drafted by AI, editable |
| Business name and logo | Your Shopify store's, editable |
| Final URL | The landing page you choose: a product, a collection, the home page |
| Budget and countries | Set by you |
How it works
1. Connect Google Ads in Connectors. 2. Open Store › Ads, New campaign, and choose Google. 3. Set the daily budget and the countries. 4. Select from Studio: the creations that become the images; they are cropped to landscape and square for you. 5. Let the AI draft the headlines, the long headline and the descriptions, then rewrite what you want. 6. Launch. The campaign is created paused and switched on last; results then sit in Store › Ads beside Meta, Pinterest and X.
Why it matters for a fashion brand
Google recommends many distinct pictures per asset group, and a small brand rarely has them. The studio makes them from one product photo: the piece on a model, ghost mannequin, the same piece in other colours. The texts are the other gap, and they are drafted from your brand and your product instead of left for Google to invent.
Pinterest and X are in Pinterest and X ads from your creations; Meta's carousel in Meta carousel ads from your creations.
