How to Create a robots txt-Styled Indicator for Images (Adobe’s New AI-Training Opt-Out)

Adobe has just rolled out a free “Content Authenticity” web app that lets you stamp any JPG or PNG with tamper-proof metadata, known as Content Credentials.

Inside that tag is a simple tick-box: “Do not use for AI training.” It’s the picture equivalent of writing Disallow: / in robots.txt.

Google has already announced that it will display such C2PA* metadata in its “About this image” panel, allowing authentic, well-tagged pictures to stand out in Search and Images.

*C2PA = the open standard backed by Adobe, Google, Microsoft, BBC and others.

1) Why does this even matter

AI models absorb billions of images from the open web.

That means the product photos you shot, the infographics you paid for, and even team head-shots can quietly end up training someone else’s AI. Adobe’s new “Content Credentials” tag lets you plant an in-file “No AI” sign (like a mini robots.txt) and prove you’re the original creator. Google has already stated that it will read this tag and display it in its new “About this image” panel.

3) How to do it (60-second version)

1. Open: contentauthenticity.org/app (Adobe’s free web tool).
2. Drag & drop up to 50 images (JPG/PNG).
3. Fill your Name/Site URL → Tick “Do not use for AI training.”
4. Click Attach & Download → Adobe spits out tagged images.
5. Upload those images to your CMS as usual (alt-text, compression, etc.).
6. (Optional) Install Adobe’s free Chrome extension to double-check the tag is there.

4) Other smart things you can do next

• Bake it into your workflow: Add “Add Content Credential” right after “compress image” in your standard checklist.
• Tag at source: Photographers using Photoshop 2024+ can embed the tag during export—no extra steps later.
• Track developments: Keep an eye on which AI companies publicly commit to honoring the tag and update your policy accordingly.
• Educate clients: If you run a content or SEO agency, offering “AI-safe image delivery” is an easy value-add.

Quick-Guide for Designers & Developers

• Tag at export: Photoshop 2024+ can embed Content Credentials right in “Save As”—ask your tool to remember the setting.
• Batch it: Make Step 4 a default in your export presets so you never forget.
• Educate clients: Inform them that their licensed photos now ship “AI-safe”—it’s a valuable added benefit.
• Stay tuned: Adobe is pushing big AI companies to honor the tag; Reuters notes industry talks are underway.

Google’s ranking brain has grown beyond keywords.

It now asks, “Who made this? Can I trust them?” That’s the heart of Experience, Expertise, Authoritativeness, Trust (E-E-A-T).

When you embed Content Credentials, you’re giving Google a cryptographic autograph.

In September 2024, Google announced its “About this image” panel: click the three dots on a picture and it reveals whether C2PA credentials exist and if the image was AI-generated or camera-made. Sites that provide clear provenance gain an instant credibility bump, especially on news, YMYL, and e-commerce queries.

From a crawl-budget view, tagged images also help Google disambiguate duplicates.

If five sites hot-link the same meme, but only yours carries a verifiable credential, Google can connect the originality dots quicker—less wasted crawl time, more love for your canonical URL.

Add a descriptive alt-text and your now-authentic image works like schema for pictures: structured, machine-readable proof of who, where, and when.

Real-case scenario

Visualise Asha, a freelance photographer in Mumbai.

She shoots latte art for a local café and posts it on her portfolio. Six months later, a generative-AI ad shows her foam heart swirling inside a watch commercial. Asha can’t afford legal wars, but she can prove the photo was hers first—because she attached Content Credentials before upload.

She sends the hash to the brand; they settle, and she even lands a paid shoot. Small creator, big power move—all thanks to a sixty-second habit change.

This is in process

Adobe says it is “in talks with every major model builder” to honor the flag.

Will all of them comply?

Probably not right away, but the momentum is real. Meta, Microsoft, the BBC, Nikon, and even chip-maker Qualcomm sit on the same C2PA steering committee.

Regulations in the EU and several U.S. states already hint that respecting provenance data could become mandatory. As adoption spreads, images without credentials may look anonymous—like blogs without HTTPS locks did in 2016.

For SEOs, that means early adopters get a trust advantage purely on technical cleanliness, just as schema adopters did a decade ago. And if the worst happens—your picture goes viral without credit—you still hold the original cryptographic receipt.

Great SEO today is less about tricking algorithms and more about signalling realness. We optimise paragraph structure, page speed, and schema so machines can understand us. Content Credentials let us do the same for pictures: speak a language bots respect while also serving human trust.

You don’t need a dev sprint, a plugin, or a budget meeting. All it takes is one new habit: stamp before you ship. Do that and you protect your art, boost your search visibility, and send a broader message—that creators, large and small, still own their narrative in an AI world hungry for data.

So next time you export a hero image, give it an invisible shield. It is the smallest SEO tweak with the biggest long-term payoff.
