How to Solve Alt Text for Accessibility Issues
If you run a website—whether it’s an e-commerce store, blog, SaaS platform, or landing page—alt text for accessibility is one of the most impactful yet overlooked details you can optimize. It ensures your content is usable for visually impaired users who rely on screen readers, keeps your site compliant with global accessibility standards, and helps search engines understand your images for better visibility.
Yet for many website owners, creating high-quality, accessible alt text feels like a tedious, error-prone chore. Manually writing descriptions for every image is time-consuming, easy to rush, and often results in vague, non-compliant text that fails to serve its purpose. That’s where purpose-built tools come in: designed to take the guesswork out of the process, they help you solve alt text accessibility issues quickly, consistently, and without compromising on quality.
In this guide, we’ll break down exactly what alt text for accessibility requires, the most common mistakes to avoid, and how to streamline the process for every image on your site.
What Is Alt Text for Accessibility, and Why Does It Matter?
At its core, alt text (short for alternative text) is a concise, descriptive phrase that explains the purpose and content of an image. For accessibility, it serves two non-negotiable roles:
- Screen reader compatibility: When a visually impaired user navigates your site, their screen reader reads the alt text aloud, letting them understand the image’s role in your content.
- Compliance with global standards: Standards like WCAG 2.1 AA and Section 508 require non-decorative images to have clear, functional alt text. Missing or poor-quality alt text can lead to accessibility barriers and compliance risks for public-facing sites.
Beyond accessibility, well-written alt text also helps search engines interpret your images, improving your chances of ranking in image search results and boosting overall page relevance.
Key Rules for Accessible Alt Text (The Non-Negotiables)
Not all alt text is created equal. For text to meet accessibility standards, follow these core rules:
- Keep it concise: Most screen readers cut off text after 125 characters.
- Be specific, not vague: Describe the image’s function and key details, not generic phrases.
- Skip redundant words: Avoid “image of” or “photo of”, screen readers already mark image elements.
- Use empty alt for decoration: Pure decorative images should use
alt=""to avoid unnecessary narration.
The Most Common Alt Text Accessibility Mistakes (And How to Fix Them)
1. Missing alt text entirely
Over 60% of websites leave some images without alt text. This excludes screen reader users and breaks basic accessibility compliance.
2. Vague and generic descriptions
Phrases like “product image” or “banner picture” give no real information to users or search engines.
3. Overly long or keyword-stuffed alt text
Lengthy descriptions get truncated by screen readers, while forced keyword stuffing hurts both accessibility and SEO performance.
How to Create Compliant Alt Text Easily
Creating professional, WCAG-compliant alt text does not require writing every description manually.
The simplest approach is to upload your image, generate ready-to-use alt text instantly, and apply it directly to your website.
The whole workflow is straightforward:
- Upload any image from your device or use an existing image URL
- Generate well-structured, accessibility-friendly alt text automatically
- Copy the result and paste it into your website editor, CMS, or page builder
All generated descriptions follow accessibility best practices, stay within character limits, and avoid redundant wording.
