While both serve different purpose, we will understand the differences and how they contribute search engine-friendly online experience.
Alt Tags in SEO

These are the tags serve a dual purpose: improving accessibility for users with visual impairments and providing context to search engines for better indexing. You will wonder, when a visually impaired online user encounters an image on a webpage, a screen reader will read out the alt text, which will provide a meaningful description of the image.
Properly optimized alt tags can enhance the visibility of the content in image searches and improve the website’s ranking on search engine results pages (SERPs).

Captions, on the other hand, serve a different purpose in the online world. The primary function of Captions is to provide additional context or information about an image. Captions are visible text elements typically placed below or beside an image. Additionally they give brief description, context, or even a narrative related to the visual content.
While alt tags are vital for screen readers, captions can provide a more comprehensive understanding of the context surrounding an image.
