Alt text (alternative text) plays a critical role in web accessibility, allowing users who rely on screen readers to understand the content of images. Yet, many businesses still see alt text as a checkbox rather than an opportunity to elevate user experience (UX). As digital landscapes evolve, providing basic, vague descriptions of images isn't enough—detailed, thoughtful alt text is becoming a necessity for ensuring inclusivity and enhancing user engagement.
In this post, we'll explore what makes alt text "good," the impact detailed descriptions can have on user experience, and how AI-powered tools can help businesses generate high-quality alt text efficiently and effectively.
What Makes Alt Text ‘Good’?
Good alt text is not just about describing an image; it’s about offering a rich, contextually appropriate narrative that serves all users, especially those using assistive technologies. Three key elements make alt text effective:
- Context: Alt text should convey the image’s purpose within the content, ensuring users get relevant information. For instance, the same image used in different settings may require different alt text. An image of a dog on a pet adoption site might have alt text like, “Golden retriever puppy looking up, available for adoption,” while on a veterinarian's blog, the alt text might be, “Golden retriever puppy awaiting a check-up.”
- Detail: Alt text should provide enough detail to fully describe the image without overwhelming the user. For instance, a simple “dog” would be insufficient for someone who can't see the image, but a detailed description like “A small golden retriever puppy with a red collar sitting on green grass, looking directly at the camera” offers a more meaningful experience.
- Clarity: Alt text should be concise and clear, avoiding overly complex or irrelevant information. If there’s too much technical or extraneous detail, the description may confuse rather than inform.
Examples of Detailed Alt Text
Let’s look at examples that show the difference between basic and detailed alt text:
- Ineffective Alt Text: “Dog”
- Effective Alt Text: “Golden retriever puppy with a red collar, sitting on green grass, looking up at the camera.”
The second example offers context and paints a clearer picture, ensuring that someone using a screen reader can envision the image more vividly.
- Ineffective Alt Text: “A person at a computer”
- Effective Alt Text: “A young woman wearing glasses, typing on a laptop, sitting at a wooden desk with a coffee mug and open notebook beside her.”
Again, the detailed description in the second example provides not only an idea of the image but also a sense of environment and action, adding value for all users.
How Detailed Alt Text Enhances User Experience
Detailed alt text doesn’t just help those with visual impairments; it improves the overall UX for everyone, including people who temporarily can’t view images, like when internet connections are slow, or image loading is disabled.
Assists Screen Reader Users
Screen reader users rely on alt text to interpret images on a webpage. For users navigating the web this way, vague or missing alt text can result in frustrating experiences. Imagine landing on an article that references multiple charts or diagrams without detailed descriptions—users may miss out on critical information. Detailed alt text ensures that visually impaired users aren’t missing essential content.
Provides Context for Everyone
Even users without visual impairments can benefit from thoughtful alt text. Consider a situation where images fail to load due to a slow connection. In those cases, the alt text will show up, and this is where detailed alt text provides context that helps maintain the flow of information, ensuring users stay engaged with your content.
Additionally, alt text can also enhance SEO (search engine optimization). Search engines use alt text to understand the content of images, making well-written descriptions not only helpful for UX but also for improving a website’s visibility online.
The Challenges of Creating Detailed Alt Text
While the benefits of detailed alt text are clear, many businesses struggle to implement it consistently across their digital content. Large eCommerce sites, for example, might have thousands of images that require alt text. The sheer volume of content makes it challenging to maintain a high standard of detail and accuracy, leading to generic or poorly written alt text that diminishes the user experience.
Even companies that are committed to accessibility often lack the resources or expertise to provide thoughtful alt text for every image. This can result in shortcuts, such as automated tools that generate basic descriptions like “image of a cat,” which does little to enhance the user experience.
How AI Can Produce Quality Alt Text at Scale
This is where AI-powered solutions like A11y Alt come into play. By blending automation with human expertise, AI can help businesses produce high-quality, detailed alt text at scale, ensuring both accuracy and context.

For example, if an image is part of a product listing, the tool generates alt text that includes relevant details like color, size, and positioning, while if the same image is part of a blog, it adjusts the description to align with the article’s theme.
- Customization Options: We know that automation can't replace the nuance of human expertise. That's why our tool allows for human oversight and customization, enabling businesses to fine-tune descriptions when necessary to ensure clarity and compliance with accessibility standards.

This is particularly helpful for industries like eCommerce and media, where high volumes of visual content are the norm.
- Compliance with Accessibility Guidelines: Our tool is designed to meet WCAG (Web Content Accessibility Guidelines) standards for images, ensuring that your business remains compliant while also enhancing the user experience. This level of detail is crucial for businesses striving to build an inclusive digital environment.
