Why is the image alt tag important?

Alt tags give search engine crawlers information about what a picture is showing, enabling them to properly index an image. Alt tags are useful to search engine crawlers, but they can also affect how well your web pages rank. For this reason, you should always set alt tags for your images.

Alt text (alternative text), commonly referred to as "alt attributes," "alt descriptions," or technically wrongly as "alt tags," is a description of the appearance and purpose of an image that appears on a page and is included in the HTML code.

1. The inclusion of alternative text in photos is a fundamental aspect of web accessibility. The alt attribute of an on-page picture will be read aloud to visually challenged visitors who use screen readers.
2. If an image file cannot be loaded, alt text will be shown in its place.
