Best practices and guidelines

Alt text is key for image optimisation. It helps search engines understand your images better.

6. Avoid using phrases like “image of” or “picture of.” Start directly with what the image displays instead.
7. Assess accessibility first. Ensure that users with visual impairments can understand your images through their screen readers.
8. Take advantage of tools for alt text generation if needed. These can help create effective descriptions quickly.
9. Consistently review and adjust your alt text as necessary over time to retain relevance and accuracy.
10. Add alt text to every image on your website, not just some of them, to enhance overall SEO strength.

These guidelines will improve user experience and boost traffic to your site through effective alt text use!
