Digital marketing term
Alt Text
Alt Text is the HTML attribute that describes an image's content in words, allowing screen readers and search engine crawlers to understand what an image depicts even when they can't "see" it.
Detailed explanation
This description is defined through the alt attribute added to the img tag, and it keeps a page understandable when an image fails to load or when visually impaired users rely on a screen reader. Search engines also read this text to understand the context of an image.
A well-written description depicts the image briefly and clearly; keyword stuffing should be avoided in favor of natural, descriptive language. A large share of organic traffic from Google Images depends on this practice.
For e-commerce sites, writing consistent, descriptive alt text for product images improves both compliance with accessibility standards and visibility in image search.
