Images are an integral part of web content, and they can make a big impact on the user experience. However, they can also be a challenge for people who use assistive technology or have visual impairments. That’s why it’s essential to provide alternative text (alt text), captions, and descriptions for images. Here are five tips for creating effective image alt text, captions, and descriptions.
Main points:
Be descriptive and specific
When creating alt text, captions, and descriptions, it’s important to be as descriptive and specific as possible. Avoid using vague or generic descriptions like “picture of a woman.” Instead, provide details about the image’s content, such as “a woman holding a cup of coffee at a cafe.”
Keep it concise
While it’s important to be descriptive, it’s also important to keep alt text, captions, and descriptions concise. Try to keep the text under 125 characters so that it doesn’t become too long and difficult to read.
Use keywords
Including relevant keywords in your alt text, captions, and descriptions can help search engines understand the content of your image and improve your search engine optimization (SEO). However, make sure to use them in a natural way that makes sense in the context of the content.
Consider the context
The context in which the image is used can impact the alt text, caption, and description you choose. For example, an image used in an educational context may require more detailed descriptions than an image used for entertainment purposes. Additionally, the tone and style of the content may impact the language you use in your alt text, captions, and descriptions.

Use a tool
There are many tools available that can help you generate alt text, captions, and descriptions for your images. Some popular tools include Yoast SEO, SEMrush, and Google Vision AI. These tools can analyze your images and suggest alt text, captions, and descriptions based on their content.
Examples
Bad example:
- Alt text: Woman
- Caption: Enjoying coffee
- Description: A woman holding a cup of coffee
Why it’s bad: These examples are too vague and don’t provide any meaningful information about the image.
Good example:
- Alt text: Woman holding a cup of coffee at a cafe
- Caption: Savoring a latte at her favorite spot
- Description: A woman in a blue coat, sitting at a wooden table in a cozy cafe, holding a steaming cup of latte with both hands and looking content.
Why it’s good: These examples are specific and descriptive, providing information about the woman, the coffee, and the cafe. They also give context and detail that can help visually impaired users understand and appreciate the image.
In conclusion
In conclusion, providing alt text, captions, and descriptions for your images is essential for creating an inclusive web experience. By following these five tips, you can create effective alt text, captions, and descriptions that improve your SEO and make your content accessible to everyone.
