Here are some ways that alt text helps on social media:
Accessibility: Alt text makes social media more accessible to visually impaired users or who use assistive technologies such as screen readers.
Improved engagement: Adding alt text to images on social media can help to improve engagement by providing additional information and context to users.
Increased visibility: Some social media platforms, such as Twitter and Instagram, use the alt text as the description for an image in the feed, even if the image doesn't load. This can help increase visibility for users who cannot see the image.
Better image ranking: Including alt text can help improve the ranking of images on social media platforms and make them more discoverable in search results.
Overall, using alt text on social media can help to make images more accessible, engaging, and visible to users, improving the overall user experience on these platforms.
