In the world of website development, alt text plays a crucial role in ensuring that images are accessible to all users, including those who may be visually impaired. Alt text, or alternative text, is a brief description of an image that is read aloud by screen readers to provide context for users who cannot see the image. But what exactly distinguishes good alt text from bad alt text? Let’s dive into the details.
What is Alt Text?
Alt text is a simple yet powerful HTML attribute that can be added to the tag of an image on a website. It serves as a textual description of the image, providing information about the content and function of the image for users who may not be able to see it. Alt text also plays a crucial role in search engine optimization (SEO), as it allows search engines to understand the content of an image and rank it appropriately in search results.
Good Alt Text
Good alt text is descriptive, concise, and relevant to the image it is describing. It provides a clear and accurate representation of the image, allowing users to understand its content and context. Good alt text also includes relevant keywords that are related to the image and the overall content of the webpage. For example, if the image is of a sunset on a beach, the alt text could be “Colorful sunset over a sandy beach.”
Bad Alt Text
On the other hand, bad alt text is vague, irrelevant, or missing altogether. Bad alt text fails to provide meaningful information about the image, leaving users confused or unable to understand its significance. Examples of bad alt text include generic phrases like “image” or “photo,” as well as long strings of keywords that do not accurately describe the image. Bad alt text can also be misleading, causing users to have a misinterpretation of the image.
Why Does Alt Text Matter?
Alt text is essential for ensuring that all users, regardless of their abilities, can access and understand the content of a website. It plays a critical role in making websites more inclusive and user-friendly for everyone. In addition to improving accessibility, alt text also plays a significant role in SEO by helping search engines index and rank images appropriately.
Best Practices for Alt Text
When creating alt text for images on a website, it is essential to follow some best practices to ensure that it is effective and beneficial for users. Some tips for creating good alt text include:
- Be descriptive: Provide a concise and accurate description of the image.
- Use keywords: Include relevant keywords that describe the image and the content of the webpage.
- Keep it concise: Aim for alt text that is brief and to the point, avoiding unnecessary details.
- Avoid keyword stuffing: Do not overuse keywords in alt text, as this can detract from the user experience.
- Test with screen readers: Check how alt text is read by screen readers to ensure it is clear and helpful for users.

Good alt text enhances accessibility and SEO, while bad alt text can be misleading and unhelpful for users.
