The Alt-Text Provider
Most websites still treat alt text as an afterthought.
Yet it’s one of the few elements that directly improves both accessibility and search visibility.
When alt text is missing, vague, or stuffed with keywords, you’re leaving blind and low-vision users behind, and losing out on valuable image-search traffic. But writing great alt text consistently is tedious, inconsistent, and easy to skip at scale.
That’s where The Alt-Text Provider comes in.
It’s a Custom GPT built II built to generate SEO-optimised, accessibility-compliant alt text for any image quickly, consistently, and in natural language.
Just upload an image (or describe it), and the tool provides five context-aware alt-text options, each designed to balance clarity, compliance, and search value.
The best part, it’s completely free.
What It Does
The Alt-Text Provider turns image optimisation into a fast, repeatable process.
It analyses an uploaded image (or a short image description) and produces five SEO-friendly alt-text options, each written to meet both accessibility standards and modern on-page SEO principles.
Each output follows alt-text best practices (concise, descriptive, keyword-aware but never spammy) so every image can carry its weight in both accessibility and search.
You can use it to:
Generate descriptive alt text for blogs, e-commerce, or landing pages.
Optimise existing image libraries during a site refresh or accessibility audit.
Standardise tone and format across teams handling large volumes of visual content.
In short, it’s an instant assistant for writing accurate, human-sounding image descriptions that help both your users and your rankings.
Who It’s For
The Alt-Text Provider is designed for anyone managing content where visuals matter — but time and consistency are limited.
Content writers & editors who need fast, compliant image descriptions without breaking writing flow.
SEO specialists aiming to boost image visibility and on-page quality signals.
E-commerce teams managing hundreds of product images where alt text is critical for accessibility and conversion.
Web developers & accessibility leads ensuring every image meets WCAG and ADA standards before launch.
If your workflow involves publishing, optimising, or auditing visual content, this GPT adds structure, accuracy, and speed, without compromising compliance or creativity.
The Core Problem It Solves
Thousands of pages go live every day with missing, vague, or incorrect alt text:
“image123.jpg”
“screenshot”
“photo of product”
These descriptions fail both users and search engines. They don’t describe, they don’t differentiate, and they definitely don’t drive visibility.
The result?
Accessibility audits flag compliance issues.
Screen readers deliver unhelpful or missing information.
Image search traffic stays untapped.
Writing proper alt text for every image is tedious and easy to overlook — especially at scale.
The Alt-Text Provider fixes that by generating accurate, SEO-conscious, human-readable alt text in seconds. It makes accessibility scalable, consistent, and built into your content process.
How It Works
The Alt-Text Provider is designed to be simple, fast, and accurate. No prompts or guesswork required.
Upload or paste your image: Drop in an image file or paste an image link directly into the chat.
Add optional context: Include the image’s purpose, page type, or target keyword (e.g., “golf hoodie product image” or “team photo for about page”).
Generate five options: The GPT analyses visual elements, tone, and context — then produces five distinct alt-text variations, each balancing accessibility, clarity and SEO optimisation.
Choose your best fit: Review, refine, or copy the alt-text directly into your CMS or image tag.
Every output follows best-practice principles:
Descriptive, not decorative.
Keyword-aware, not keyword-stuffed.
Readable aloud by a screen reader.
In seconds, you get high-quality, compliant alt-text ready to publish, without the manual grind.
Limitations
The Alt-Text Provider is built to improve speed and consistency, not to replace human judgment entirely.
It excels at generating clear, accurate, SEO-aligned alt text, but there are limits to what automation can do responsibly:
❌ It doesn’t interpret complex charts or data visualisations. These still need human context to explain meaning, not just appearance.
❌ It can’t infer brand-specific messaging or tone unless you provide that context in your prompt.
❌ It won’t write decorative or marketing-heavy captions. The outputs are factual, not promotional.
❌ It doesn’t auto-insert alt text into CMS systems. You’ll still need to apply it manually.
❌ It focuses on accessibility and SEO accuracy, not broader metadata fields like filenames or structured data.
Summary
The Alt-Text Provider brings accessibility and SEO together, helping teams create compliant and descriptive image alt text in seconds.
Instead of manually writing hundreds of lines or leaving images unlabelled, you can generate five high-quality, human-sounding options per image, each crafted to balance clarity, inclusivity, and search value.
For content, SEO, and e-commerce teams, it’s a simple way to make every image pull its weight, improving both user experience and AI-readability across your site.
