What is alt text on Instagram, and how does it help?

Alt text (alternative text) is a hidden description field you can fill out before posting on Instagram. It’s not visible to viewers in the main post, but it serves two purposes: accessibility (helping visually impaired users understand your image through screen readers) and SEO (helping Instagram’s algorithm understand and categorize your content). Adding descriptive, keyword-rich alt text improves the chances your post will appear in relevant searches. You’ll find the alt text option in the advanced settings before you publish a post.
