AI-generated images and SEO: alt text, metadata and licence terms
Short answer
Google treats AI-generated images like any other image: use descriptive alt text, a clear filename, a sensible format and placement next to relevant text. What changes is metadata and rights. Google supports IPTC Digital Source Type values, such as trainedAlgorithmicMedia, to state that a model created the image, and asks for it on AI-generated e-commerce images. Before you publish, check the tool's licence for commercial use and watermarks, because they differ by plan.
This is a documented guide, not a test. It is built from Google Search Central's image, image-metadata and generative-AI pages, and from the pricing and FAQ pages of the two tools used as examples, checked in October 2026. CheaperStack has not generated images with these tools for this page and publishes no results.
The basics Google documents for every image
| Recommendation | What Google says | For AI images |
|---|---|---|
| Alt text | The most important attribute for giving an image metadata. Descriptive, in context, no keyword stuffing | Describe what the image shows and why it is there. Never paste the generation prompt |
| Filename | Short and descriptive, not image1.jpg | Rename exports; tool filenames are usually random |
| Format | BMP, GIF, JPEG, PNG, WebP, SVG and AVIF are supported | Export or convert to WebP or AVIF for speed |
| Placement | Near relevant text, on relevant pages | Do not use an AI image as decoration on an unrelated page |
| Quality and speed | Sharp images attract more clicks; large ones slow pages | Upscale only when needed, then compress |
| Markup | Use img elements with a src fallback; an image sitemap can help discovery | Same as any image |
From Google Search Central's image SEO best practices, last updated March 2026 when read. The "for AI images" column is our reading, not Google's text.
Metadata: saying an image was made by a model
Google lets you provide image metadata through structured data or IPTC photo metadata embedded in the file, and says you need only one. If they conflict, it uses the structured data. Its documented fields include creator, credit text, copyright notice and licence. Providing a licence can make an image eligible for the Licensable badge.
For AI-generated images, Google's page lists the IPTC Digital Source Type values it supports, such as trainedAlgorithmicMedia for an image created algorithmically using a model derived from sampled content. It also says C2PA metadata, from a signer that follows C2PA 2.1 or later, can appear in the "About this image" feature to show how an image was created or whether AI tools edited it. Google does not promise that any metadata will be displayed.
Separately, Google's generative AI guidance says to review AI output for accuracy, and, for e-commerce, to label AI-generated product images with IPTC DigitalSourceType metadata. Google also suggests explaining how content was created where readers would expect it.
What to check in a tool's licence
The rights to an AI image come from the tool's terms, not from SEO. Two examples, from their own pricing and FAQ pages:
| Term | BudgetPixel | Magnific |
|---|---|---|
| Commercial use | Free is personal use only; Basic allows limited commercial use; full commercial use from Premium | Commercial AI license listed on every paid plan, with the user responsible for third-party rights |
| Watermark | Says it adds none on any plan | Not stated on its pricing page |
| Provenance | Not stated on its pricing page | "Proof of origin and metadata for every generation" listed on Pro |
| Training on your work | May use anonymized prompts and images to improve its service; API and MCP content is not used for training | Lists that your work is never used to train its models, under Pro |
From each vendor's pricing and FAQ pages, October 2026. Terms and plan lists change; read the current terms for your plan. This is not legal advice, and Magnific itself recommends getting legal advice for branding or merchandising use.
A publishing checklist
- Check the licence for your plan before you generate, not after you publish.
- Review the image for anything that implies a fact it does not support: a product it does not show, a person who does not exist, text it got wrong.
- Write alt text by hand. It describes the image for someone who cannot see it.
- Rename the file and convert it to WebP or AVIF.
- Add IPTC Digital Source Type or equivalent structured data, especially for product images, and keep a creator or credit line.
- Test a published image to see whether your CMS or CDN kept the metadata. Optimizers can strip it; this is our practical caution, not a Google rule.
- Add a short note on how the page was made where readers would expect it, as Google suggests.
- Keep a record of which tool, model and plan produced each image.
Two tools, as examples
Both generate images, video and audio from one account, and both have an MCP connector for assistants. They differ in how you pay: BudgetPixel is credit-based with a free tier of 300 credits a month and no required subscription, and Magnific is a subscription with an annual credit allowance and no free tier listed. The direct comparison is in BudgetPixel vs Magnific.

BudgetPixel lists 100+ models on its pricing page, no watermark on any plan, and commercial use from Premium at $16.67 a month billed annually. If you sign up through this link and start a paid plan, you receive bonus credits worth 30% of that plan's monthly credits, and so do I; referral credits last 2 months. Try BudgetPixel (affiliate link).
Magnific (formerly Freepik) lists a commercial AI license on every paid plan, from €12 a month billed annually for Premium. Arriving through this link applies 20% off Premium and Premium+. See Magnific plans (affiliate link).
Who should be careful
- Product and e-commerce pages. An AI image of a product that does not match the real one is a trust problem before it is an SEO one.
- Pages about real people, places or events. A generated image can look like evidence; label it clearly.
- Brand and merchandising use. Rights depend on law and on the tool's terms; get advice.
- Sites that already have real photos. First-hand images are part of the non-commodity content Google asks for; see the E-E-A-T guide.
The verdict, by situation
| If you are… | Do this |
|---|---|
| Illustrating a blog post | Write real alt text, rename the file, check the licence for your plan |
| Selling products | Use real photos where you can; label any AI image with IPTC Digital Source Type |
| On WordPress | Test that your optimizer keeps metadata; see AI SEO tools for WordPress |
| Worried about rankings | Nothing in Google's image guidance singles out AI images; focus on quality and relevance |
| Planning for 2027 | Keep provenance records now; Google already documents C2PA and IPTC fields |
Frequently asked questions
Does Google penalize AI-generated images?
Google's image guidance does not single out AI-generated images for a penalty. It asks for the same things as any image: descriptive alt text, relevance to the surrounding text, quality, and honest metadata. For AI-generated product images in e-commerce, Google's generative AI guidance asks for IPTC DigitalSourceType metadata.
Do I need to label AI-generated images?
Google lists IPTC Digital Source Type values, including trainedAlgorithmicMedia, that you can embed to say an image was created by a model, and asks for it on AI-generated e-commerce images. Beyond that, labelling depends on your own policy and local law, which is a legal question rather than an SEO one.
Is alt text still important for AI images?
Yes. Google calls alt text the most important attribute for providing metadata about an image. Describe what is in the image and why it is on the page, in plain words, without keyword stuffing.
Can I use AI-generated images commercially?
It depends on the tool and the plan. BudgetPixel allows commercial use from its Premium plan and personal use only on Free. Magnific says you can use AI images commercially if you respect third-party rights, and recommends legal advice for branding and merchandising.
Will my CMS or CDN remove the metadata?
It can. Image optimizers and some plugins strip embedded IPTC data when they compress or convert files. Google uses structured data if the two conflict, so keep the information in your markup too and test a published image.
