Let's first understand what Alt-text is before we talk about the app:
Alt-text (alternative text) is used in HTML with the alt attribute inside an <img> tag to describe the content of an image. It serves two main purposes: it improves web accessibility by helping screen readers convey image information to visually impaired users, and it provides fallback text if the image fails to load. A basic example looks like this:
<img src="product.jpg" alt="Red cotton t-shirt with round neck">
In this example, the alt attribute provides a clear description of the image, which is beneficial for both users and search engines.
Adding Alt-text in Shopify Product Images:
In Shopify, alt-text can be added to each product image to describe what the image shows. This helps visually impaired users and also improves SEO. Merchants can manually add alt-text by going to Shopify admin → Products → Media, clicking on an image, and entering a descriptive phrase in the “Alt text” field. For example, describing a product image as “Red V-neck cotton t-shirt on hanger” helps search engines index the image and makes your store more accessible to all users.
As a Shopify store owner, it's important to add alt-text to each product image along with its variant details to improve visibility and rankings on search engines.
Issues with adding alt text in Shopify product images:
Adding alt-text manually to every image is time-consuming, especially for stores with hundreds or thousands of products. It also leads to inconsistencies, human errors, or skipped images — affecting accessibility and SEO performance.
