The Importance of Alt Text for Images

Alt text, also known as alternative text, is a description of an image that is displayed if the image cannot be loaded or if a user is using a screen reader. Alt text is an important part of website accessibility and can also have an impact on search engine optimization.

Properly using alt text can help improve the accessibility of your website and also help search engines understand the content of your pages better. Here are some best practices and do’s and don’ts for using alt text effectively:

Best Practices for Alt Text

Be Descriptive

When writing alt text, it’s important to describe the image accurately and in as much detail as possible. This helps users who cannot see the image understand what it represents. Use specific details, such as colors, shapes, and objects, to describe the image.

Use Relevant Keywords

Include relevant keywords in the alt text, but only if they accurately describe the image. Don’t stuff keywords into the alt text just to try to improve search engine rankings. Keyword stuffing can be seen as spammy by search engines and can hurt your rankings.

Keep it Concise

The alt text should be concise and to the point. Aim for 125 characters or less, if possible. However, don’t sacrifice accuracy for brevity.

Use Proper Grammar and Punctuation

Use proper grammar and punctuation in the alt text. This helps make it easier for users and screen readers to understand the description.

Use Empty Alt Text for Decorative Images

If an image is purely decorative and doesn’t add any information to the content, use empty alt text (alt=””). This tells screen readers to skip over the image and focus on the content.

Use Alt Text for Important Images

Use alt text for important images, such as images that convey information or help users navigate the website. This helps ensure that all users can access the information on the page.
