What Are Alt Tags?

Alt tags also known as alt text (‘alt’ stands for ‘alternative’) is the textual description of your images. They are important for both accessibility and SEO.

The main function of the alt tag is to help people with eyesight disabilities understand what an image is about.

Alt tags are generally entered manually. However, you can also implement some elements of automation (for example, through a plugin you can instruct Shopify to automatically add your page title as an alt tag for images on the page).

Are Alt Tags Important for SEO?

Alt tags are very important for SEO because search engines like Google can’t read the content of an image.

Alt tags serve the purpose of describing what the image is about. This helps search engines better understand and rank your pages and images.
