Best Practices for Writing Alt Text
When it comes to writing alt text, following best practices is crucial to ensure its effectiveness. By adhering to these guidelines, you can create alt text that not only enhances accessibility but also improves your website’s SEO.
1. Be Descriptive and Accurate
The main purpose of alt text is to provide a concise and accurate description of the image.

2. Keep it Concise
While it’s important to be descriptive, it’s equally important to keep your alt text concise.

When writing alt text, consider the formatting and structure of your text. Avoid using special characters, excessive punctuation, or unnecessary capitalization.
