Direct Answer Box
Alt-text is short descriptive text added to images. It started as an accessibility tool, but now it’s a powerful AI visibility signal. The precise alt-text helps AI understand your images, connect them to your brand, and show you in search results.
Snippet: Alt-text started as accessibility, but now it’s an AI visibility signal.
Why Is Alt-Text Important for AI Visibility?
Think of alt-text as the caption AI actually reads. Without it, AI is left guessing. With it, your image becomes a searchable, branded visibility asset.
Alt-text helps you:
Show up in AI answers (Google AI Overviews, Perplexity, ChatGPT).
Strengthen your digital footprint (consistent brand + service + location).
Support accessibility for users with screen readers—building both goodwill and authority.
FoundFirst Tie-In: Alt-text touches three of the Eight Signals—Digital Footprint (Signal 1), Local Relevance (Signal 4), and AI-Specific Signals (Signal 7). Every image is a chance to reinforce your brand.
Snippet: Without alt-text, AI guesses. With it, your images become searchable assets.
How Do You Write Alt-Text That Works for AI?
The best alt-text balances clarity, context, and keywords.
Be specific: “Colorado Springs personal-injury attorney shaking hands with a client in office” is better than “lawyer and client.”
Add brand signals: Mention your business name when appropriate.
Include context: Describe colors, actions, or settings that matter.
Keep it natural: One sentence, less than 125 characters if possible. Think of how you would describe the picture to a colleague over a phone call.
Answer the basics: Who is in the picture, what is happening, where it takes place, and how/why it matters.
Snippet: Good alt-text is specific, branded, and contextual.
How Do You Add Alt-Text in Practice?
Writing strong alt-text is step one. Step two is making sure it actually gets attached to your images wherever they live.
On Websites: Most platforms (Wix, WordPress, Squarespace) let you add alt-text when you upload an image. Look for “Alt text” or “Image description.” This is the version Google and AI scrapers read directly.
Example: Every blog we publish on Your AI Wizards includes a hero image with descriptive alt-text tied to the blog theme—for example: “Purple wizard robot showing a dictionary definition for AI clarity” (added through Wix’s SEO function). If the process changes, or if you’ve never done it before, tools like ChatGPT or Perplexity can guide you step by step.
On Social Media: LinkedIn, Facebook, and X all allow custom alt-text when you upload a photo. Again, don’t worry about what to say, Large Language Models (LLMs) can help you draft, but as always review and rewrite into how you would describe the picture. Don’t skip this step, it’s not just accessibility, it’s AI visibility.
LinkedIn: When uploading a photo, click the ALT button. In the pop-up, type your alt-text.
Facebook: After adding an image, click Edit → Alternative text. Replace the auto-generated text with your own description. Facebook’s automatic suggestions are often way off — sometimes hilariously wrong — so always write your own.
X (Twitter): Once your image is uploaded, click Edit, then the ALT option, and type your description.
Using Comments: When a platform doesn’t expose alt-text publicly—or when you bulk-upload content using tools like SocialChamp or SocialPilot—you can reinforce visibility by adding descriptive text in the first comment. While not a substitute for true alt-text fields, it gives AI another path to read your content.
Snippet: Adding alt-text at upload and reinforcing it in comments maximizes AI visibility.
Case Study: Weak vs. Strong Alt-Text
Strong alt-text should be descriptive enough to answer the questions “Who,” “What,” “Where,” and “When.”
❌ Weak Alt-Text: “car accident”
✅ Strong Alt-Text: “Colorado Springs attorney reviewing front-end damage to client’s car after intersection accident on a snowy day.”
❌ Weak Alt-Text: “this is us”
✅ Strong Alt-Text: “Joy Morales and Tim Hallam presenting AI visibility strategies at the AI In Reach event in Colorado Springs.”
Without that detail, AI might misinterpret. For example, a handshake photo could easily be labeled “two men holding hands” instead of “closing a deal.” Alt-text ensures you guide the narrative, not leave it to chance.
Snippet: Adding who, what, where, and when makes your images work harder for you.

How Do Different Platforms Treat Alt-Text?
For our technical friends, and for those who just want to know what’s going on behind the scenes, here’s how AI finds and interprets your images:
Websites: Alt-text + file names are indexed directly by Google. Schema markup (like ImageObject) can reinforce context.
LinkedIn & Facebook: Both allow custom alt-text. AI scrapers read it regardless of whether people see it. Using the same exact alt-text across platforms strengthens your footprint and avoids confusion.
X (Twitter): Alt-text is available per image; good for both accessibility and AI discoverability.
Don’t forget: AI also reads file names. A keyword-rich file name like colorado-springs-attorney-consultation.jpg reinforces your alt-text, while IMG_1234.jpg wastes the opportunity.
Snippet: Consistent alt-text across platforms strengthens your digital footprint.
The Alt-Text Visibility Checklist
When you’re ready to post an image, remember these rules:
✅ Every image has alt-text.
✅ One clear sentence, not keyword stuffing.
✅ Mentions brand or service when relevant.
✅ Location included if local relevance matters.
✅ File name is also keyword rich.
Snippet: Alt-text plus keyword-rich file names deliver a double visibility boost.
What’s the Future of Alt-Text in AI Search?
Multimodal AI models (like GPT-4o, Gemini, Claude Sonnet Vision, and Perplexity) can “see” images directly. What alt-text does is add cues to confirm what they see.
Alt-text:
Reinforces what AI detects visually.
Provides brand + location signals AI might not “see” in the pixels.
Prepares your content for the next wave of AI search, where images and text blend seamlessly.
And as recent site scans show, AI is already getting sharper: not only can it detect a blog page, but it can also now identify individual blog titles and posting dates. Alt-text is one more way to feed AI clear, crawlable context.
Snippet: Alt-text evolves with AI — what you write today trains tomorrow’s answers.
Common Mistakes to Avoid
❌ Leaving alt-text blank.
❌ Using auto-generated file names like IMG_1234.jpg (instead of keyword-rich names).
❌ Stuffing keywords (“lawyer, attorney, car accident, injury, lawsuit”).
❌ Skipping brand/location context.
Snippet: Keyword-rich file names deliver a double visibility boost.

Q: Can alt-text help me rank locally?
Absolutely. Adding “Colorado Springs” or your location ties your images to local AI search results.
Snippet: Local keywords in alt-text help your business surface in AI-driven local search.
Wrap Up

Beauty is in the eye of the beholder; clarity is in the eye of AI.
Snippet: Alt-text ensures AI doesn’t just see your images—it understands them.
TL;DR
Alt-text transforms every image into a visibility signal. Write short, descriptive, keyword-rich sentences for every image so AI knows exactly what it’s seeing—and connects it back to your business.

Next Steps: Be Found First with Alt-Text
You can’t look at this as “just another thing to check off your to-do list.” Alt-text is a visibility multiplier. Done right, it ensures AI understands not just what’s in your pictures, but what they mean for your business.
Step 1: Audit your images.
Look at your website, blogs, and social posts. Do they all have alt-text? Are the file names keyword-rich or still “IMG_1234.jpg”?
Step 2: Write smarter alt-text.
One sentence. Clear, specific, and contextual. Add brand and location when relevant. Make it sound like how you’d describe the picture to a colleague.
Step 3: Apply consistently.
Use the same alt-text across platforms to strengthen your digital footprint. Add it at upload, and reinforce in comments when needed.
Step 4: Review quarterly.
AI search evolves, refresh your alt-text and file names to keep them aligned with your current services, locations, and branding.
