What is Image Alt Text?
Image alt text, short for alternative text, is an HTML attribute applied to image tags. It serves as a textual description of an image on a webpage. If an image fails to load, the alt text will be displayed in its place. Moreover, screen readers use alt text to describe images to visually impaired users, enhancing the web's accessibility.

The Importance of Image Alt Text
Accessibility
Alt text is essential for making the internet accessible to all users, including those with visual impairments. Screen readers rely on alt text to convey the content and purpose of images, ensuring a better user experience for everyone.

SEO Benefits
Search engines can't interpret images directly. Instead, they rely on alt text to understand the context and content of an image. Properly crafted alt text can help search engines index your images correctly, potentially improving your site's search rankings.

User Experience
In cases where images fail to load due to connectivity issues or errors, alt text provides a fallback that informs users about what they should be seeing. ...
... This maintains the context and continuity of your content.

How to Maximize SEO Impact with Image Alt Text
Be Descriptive and Specific
Describe the image as clearly and specifically as possible. Instead of using a generic description like "dog," use "Golden Retriever playing fetch in the park." This not only helps with SEO but also provides valuable context for users relying on screen readers.

Use Keywords Wisely
Incorporate relevant keywords naturally into your alt text. Avoid keyword stuffing, which can lead to penalties from search engines. Instead, focus on creating meaningful descriptions that seamlessly include keywords.

Keep It Concise
While being descriptive, aim to keep your alt text concise. Ideally, the alt text should be around 125 characters or less. This ensures that it is easily readable by screen readers and fully visible in most browsers if the image fails to load.

Avoid Redundancy
Do not include phrases like "image of" or "picture of" in your alt text. Screen readers and search engines already know that the text is describing an image. Jump straight into the description to keep it concise and effective.

Contextual Relevance
Ensure that the alt text is relevant to the surrounding content. This contextual relevance helps search engines understand how the image relates to the rest of the page, boosting your SEO efforts.

Include Alt Text for Decorative Images
If an image is purely decorative and doesn't add informational value, use an empty alt attribute (alt="). This tells screen readers to skip the image, reducing unnecessary interruptions for users with visual impairments.

Regular Audits and Updates
Periodically review your website's alt text to ensure it remains relevant and effective. As your content evolves, updating your alt text can help maintain its SEO impact and accessibility.

Examples of Effective Alt Text

Image: A photo of a group of students studying together in a library.
