Alt Description, Alt Tag, Alt Text
In HTML, the alternate text for an image.
The alternate text is specified inside the IMG tag, and is displayed in place of the image as it loads onto the page. The alt attribute is sometimes mislabeled as an alt tag, however the alt attribute is defined within HTML tags rather than being a tag. The text displayed is generally a description of the image, and can be useful in search engine optimization (SEO) as the description includes product image information interpretable by web crawlers.
