Alt tags are HTML attributes that provide search engines with text as an alternative to the image content. So using alt tags for your images can positively impact your SEO as they help search engines understand what an image is about. We will quickly show you how to edit the alt tags of the pictures in your Gallery and Content widgets (pictures in slideshows and image widgets don't have alt tags). 💡 Note: The text of the alt tag also appears inside the image container in cases when the image cannot be displayed.
