How Do You Ensure the Quality and Relevance of Alt Text to the Images?

Images paint a thousand words, but for those who can’t see the canvas, those words need to be carefully chosen. Alt text represents those descriptive snippets attached to images that serve a crucial dual purpose: enhancing accessibility for the visually impaired and boosting your website’s SEO. It’s a known fact that missing alt text contributes to approximately 61% of all reported homepage accessibility errors.

Images are powerful storytelling tools, but their voices are lost on those who can’t see them. Alt text steps up as the interpreter. However, to truly amplify the image’s message and champion accessibility, we need to craft alt text with intention and precision, ensuring it is accurate, informative, and relevant to the experience.

 Why do Quality and Relevance Matter in Alt Text?

Imagine a blind person navigating a website with poorly written alt text. ‘Picture of a flower’ might be informative, but it doesn’t paint a vivid picture. After all, it has been reported that about twelve million internet users have impaired vision.

‘A vibrant red rose in full bloom, dewdrops glistening on its petals’ is a whole different story. It evokes emotion, conveys context, and significantly improves the user experience.

High-quality and relevant alt-text best practices benefit everyone, not just those with visual impairments. It:

• Boosts SEO: Search engines crawl alt text to understand the content of your images, improving your website’s visibility for relevant search terms.
• Enhances user experience: Descriptive alt text provides context and clarity, making your content more engaging and accessible for everyone.
• Complies with accessibility guidelines: Well-written alt text is essential for meeting WCAG (Web Content Accessibility Guidelines) standards, ensuring your website is inclusive for all users.

Understanding the Importance of Good Alt Text

Writing effective alt text goes beyond simply describing the image itself. It’s about providing context and conveying the image’s message concisely and accurately. Here are some key points to remember:

• Keyword Integration: While avoiding keyword stuffing, include relevant keywords organically within the alt text, especially for product images or infographics.
• Conciseness is Critical: Aim for clear and concise descriptions, typically between 125 and 150 characters. Avoid being overly verbose or repeating image captions.
• Context Matters: Consider the purpose of the image and its role within the page content. Describe its relationship to the surrounding text and its contribution to the overall message.
• Decorative vs. Informative: For purely decorative images, consider using a null alt text (“”) to avoid cluttering search engine results.
• Image types: Consider using different alt text approaches for different image types, like infographics, charts, or diagrams. These might require more detailed descriptions to convey their information accurately.
• Multiple images: When using multiple images close to each other, ensure each has a distinct alt text that provides unique information and avoids redundancy.
• Testing and refinement: Regularly test your alt text with screen readers and accessibility tools to ensure it’s effective and accurate.

Tailoring Your Alt Text Approach

Alt text may seem like a small detail, but its impact is significant. By investing in good alt text, you’re making your website more accessible and searchable. You’re also creating a more inclusive and user-friendly experience for everyone.

Different images demand different descriptions. Here are some handy alt-text best practices for various scenarios:

• Photos: Describe the people, objects, and actions happening in the photo. Add context if needed, like location or event. For example, instead of “Woman running,” try “Smiling woman jogs through a park, enjoying the autumn colors.”
• Infographics and charts: Briefly explain the key data points and their relationships. Don’t repeat the entire chart in text, but provide enough information to understand its essence.
• Illustrations and diagrams: Describe the main concept or process depicted. For complex visuals, consider layering the alt text, starting with a concise overview and progressively adding details in subsequent alt attributes.
• Decorative images: If an image purely adds visual appeal without adding information, consider using CSS instead of HTML, eliminating the need for alt text.
