What are Alt Texts?

Alt text, short for alternative text, is text that is included in a webpage’s HTML code to describe an image. It is used to provide a textual description of an image for those who are visually impaired or have limited vision. Alt text is crucial as it helps search engines understand and index images, and it also allows individuals using screen readers to comprehend the content of an image.

Where to Insert Alt Texts?

Alt text should be inserted in the HTML code of an image tag. The alt attribute is used to specify the alt text for an image. When an image cannot be displayed, the alt text will be shown instead.

Here is an example of how to insert alt text:

<img src="image.jpg" alt="Description of the image">

It is important to note that alt text should be added to all images on a webpage, including decorative images that do not convey any meaningful information. For decorative images, an empty alt attribute can be used:

<img src="decorative-image.jpg" alt="">

How Does a Good Alt Text Look?

A good alt text should accurately and concisely describe the content and purpose of an image. It should provide enough information for someone who cannot see the image to understand its context. Here are some guidelines for creating effective alt text:

  • Be descriptive: Clearly describe what the image depicts or conveys.
  • Keep it concise: Use concise language to convey the essential information.
  • Avoid keyword stuffing: While it is important to optimize alt text for search engines, avoid excessive use of keywords. Focus on providing a meaningful description instead.
  • Use relevant information: Include relevant details such as the subject, action, or key elements of the image.
  • Avoid subjective language: Stick to objective descriptions rather than adding personal opinions or interpretations.
  • Consider the context: Take into account the surrounding content and ensure the alt text provides context and adds value to the overall message.

The Attributes of a Good Alt Text

When creating alt text, there are certain attributes that make it effective:

  • Accurate: The alt text should accurately describe the image.
  • Relevant: The alt text should be relevant to the image and the surrounding content.
  • Concise: The alt text should be concise and to the point.
  • Meaningful: The alt text should provide meaningful information about the image.
  • Descriptive: The alt text should describe the content and purpose of the image.
  • Accessible: The alt text should be accessible to individuals who are visually impaired or have limited vision.

By following these guidelines and incorporating the attributes of a good alt text, you can ensure that your images are properly described and accessible to all users. This not only benefits individuals with visual impairments but also helps improve the visibility and searchability of your website.
