You're inside the Google Ads interface, setting up an asset group for a Performance Max campaign. You need lifestyle images for your product but don't have a photo shoot. The interface offers you a button: "Generate images with AI." You click it, write a prompt, and in 30 seconds you have 4 images ready to add to the asset group.
This is Asset Studio Google Ads, the tool integrated into Google Ads that uses Gemini, Google's AI model, to generate images and text variants directly inside the campaign interface. It's not a separate tool to integrate via API: it's inside Google Ads, accessible during the creation or editing of any campaign that uses visual assets.
In this article I clearly distinguish what Google has officially documented from what emerges from direct use of the tool on real campaigns.
What Asset Studio Is and Where to Find It in Google Ads
Asset Studio Google Ads is the creative workspace integrated into the Google Ads interface that lets you create, manage, and generate assets, images, texts, videos, using AI tools powered by Gemini. It was progressively introduced in 2024–2025 as an evolution of asset management in Google Ads.
Asset Studio is not just an image generator, it is also a centralized library for all account assets. This second aspect is often overlooked: having all images, texts and videos used across all account campaigns in a single place, with visibility on where each asset is in use and which receive the best ratings, is a significant organizational advantage regardless of AI generation.
How Gemini Generates Images in Asset Studio
The image generation feature in Asset Studio Google Ads uses Gemini, specifically the Imagen model integrated into the Google ecosystem, to generate advertising images from a text prompt.
The generation process works as follows: you write a prompt describing the image (e.g., "woman using laptop in a bright office, editorial style, neutral background"), select the desired format or formats, and the system generates 4 variants per format. You can regenerate, edit the prompt, or select the best variants to add to the asset group.
✅ Generation from text prompt
Describe the image in English or your language. The system interprets the prompt and generates 4 variants. You can specify photographic style, subject, composition, dominant color. The prompt is analyzed against Google's policies before generation.
✅ Website-based generation
Asset Studio can analyze the advertiser's website and generate images consistent with the brand and sector, without requiring a manual prompt. Useful for those without prompt engineering experience who still want relevant images.
✅ Editing existing images
You can upload an existing image and ask Gemini to modify it, change the background, add elements, remove elements, adapt it to a different format. Works best for simple, targeted edits.
⚠️ Generation of specific products
Asset Studio cannot generate faithful images of a specific physical product without a reference image. The system can generate "a red backpack" but not your specific backpack with your logo. This is the main limitation for Shopping campaigns.
How Asset Studio Generates Text Variants for Ads
Text generation in Asset Studio Google Ads is less well-known than image generation but equally useful, especially for those managing Google Ads campaigns across multiple accounts with limited creative budgets.
The text generation feature has one very precise primary use: reaching full asset coverage in Performance Max. Google recommends 15 headlines and 4 descriptions per asset group, a number that takes time to produce manually with meaningful variations. Asset Studio can generate a starting base that the advertiser can then refine, reducing the time needed to reach the recommended coverage.
A second, less obvious use: text generation is useful for finding communication angles you haven't considered. The system analyzes the site and can propose headlines that emphasize aspects of the product that internal communications tend to undervalue. Not as a substitute for strategic copywriting, but as input for faster brainstorming.
Which Campaigns Use Asset Studio Assets
Assets generated by Asset Studio Google Ads can be used in all Google Ads campaign types that support visual assets, with different characteristics for each.
| Campaign type | Asset Studio asset use | Main format | Limitations |
|---|---|---|---|
| Performance Max | Asset group, images and text. Primary use case for Asset Studio in Performance Max campaigns. | Landscape 1.91:1, Square 1:1, Portrait 4:5 | Does not replace real product images for the Shopping feed |
| Demand Gen | Lifestyle images and variants for Discovery, YouTube and Gmail feed. Asset Studio is particularly useful where lifestyle images are the primary format. | Landscape 1.91:1, Square 1:1, Portrait 4:5 | Variable quality on complex subjects |
| Responsive Display Ads | Images for Display placements and headline/description variants | Landscape 1.91:1, Square 1:1 | Same image quality limitations as Display images |
| App Campaigns | Visual assets for placements in the Google App Campaigns ecosystem | Multiple formats | More limited functionality compared to PMax |
Observations on Output Quality from Real Campaigns
The quality of generated images varies enormously based on prompt specificity. Generic prompts like "lifestyle product on neutral background" produce acceptable but interchangeable images. Very specific prompts , "couple aged 35–40 having breakfast in a modern Scandinavian kitchen, natural morning light, editorial photographic style", produce images significantly more consistent with a brand's visual identity. The value of Asset Studio is proportional to prompt quality.
Generated images perform comparably to photographic images in Discovery and Gmail placements. On Demand Gen campaigns with a mix of photographic images and Asset Studio-generated images, I observed no systematic CTR or engagement differences between the two types in the first 4–6 weeks. Google's optimization system distributes traffic based on actual performance signals, not the production source of the image.
Gemini-generated people still have visually recognizable AI characteristics. Even with very specific prompts, Asset Studio-generated people have a recognizable "AI aesthetic", overly uniform skin, slightly unnatural expressions, hair with repetitive patterns. In mobile placements where images are small this is less noticeable; in large-format desktop placements it is more perceptible.
Text generation is more useful as a starting point than as a final output. Automatically generated headlines cover the thematic variety Google recommends well (product features, benefits, CTAs, social proof) but rarely have the specific brand voice. The most effective workflow: generate 20–30 variants with Asset Studio, select the thematically strongest (5–6 headlines, 2–3 descriptions), and rewrite them with the brand's voice. Then add 5–6 headlines written from scratch that no AI system would have generated, those specific to the business, the customers, the sector insights.
Practical Workflow: How to Integrate Asset Studio into Creative Production
Based on direct use of the tool, the most effective workflow is neither "use Asset Studio for everything" nor "ignore Asset Studio." It's a structured combination.
- Use Asset Studio for lifestyle and context images, not specific products. Images of people using the product, environments, use situations, thematic backgrounds, these are the use cases where AI generation produces acceptable-quality output. Images of the physical product with its precise characteristics must still come from photography.
- Invest 15–20 minutes in prompt engineering before generating. Define photographic style, subject, context, color palette, mood. Test different prompts on small batches of 4 images before generating at volume. A well-written prompt reduces the iterations needed to reach acceptable images by 60–70%.
- Use Asset Studio for format variant generation. Start from the main professional image and use the tool to adapt it to missing formats, especially portrait 4:5, which many skip but is required for Discover and YouTube Shorts. Check the crop result on the subject before uploading.
- For text, generate in volume and select manually. Use Asset Studio to generate 20–30 headlines and 8–10 descriptions. Select the thematically strongest and rewrite them with the brand's voice. Then add 5–6 headlines written from scratch, those specific to the business, the customers, the sector insights.
- Monitor the asset report after 14–21 days and replace Low-rated assets. Assets generated by Asset Studio receive the same Low/Good/Best rating as photographic assets. Don't expect all of them to be Good or Best, often 30–40% of generated assets receive Low in the first weeks. Replace them with better variants.
- Keep automatically created assets disabled if you want full control. Google Ads' "Automatically created assets" feature can overwrite your creative choices with assets generated autonomously by the system. If you use Asset Studio to produce controlled assets, verify this feature is disabled.
