More about it:
Alt text offers a short description of the visual content and helps screen readers understand what is being presented. This helps to make the information more accessible to people with visual impairments, who may use screen readers or other assistive technologies to navigate the web.
This doesn’t stop here, Alt text on social media serves a similar purpose to alt text on websites, providing a brief text description of an image or graphic. On social media platforms, alt text is typically added when uploading a post, and it helps to provide context and information about what is depicted in the post.
Do you know? They are also used as a fallback when images fail to load and on social media to fill the image description.
In addition to improving accessibility, alt text can also improve search engine optimization (SEO) by providing context and additional information about the images on a page. This can help search engines better understand a page’s content and rank it higher in search results.
However, it’s crucial to use alt text in a meaningful and descriptive way rather than just including keywords in an attempt to improve SEO. This not only improves accessibility but also ensures that the content of a page or post is accurate and relevant, which is important for both users and search engines.
You can add alt text on every social media platform while posting. You will get the option to add alt text while posting, as shown screenshot below. You can manually type the alt text inside the write alt text box.
Your alt text should be focused on the main theme of the post that you are publishing, describing your post perfectly in a short text description.
