Have you ever heard that “A picture is worth a thousand words”, well that’s not necessarily true if you consider that some of the most advanced algorithms still can’t “see” and understand what an image is about like humans do. What does that mean? It means that alt text, long description and title tag are very important if you want the search engine algorithms to look at the images on your website and “understand” what they are about and how valuable they are for the content that you are sharing.
