The ALT attribute in SEO
In SEO positioning techniques, an alt attribute related to the keyword can help to better position the page in search engines. Search engines as a general rule can not read images so thanks to this type of files they can identify the content of the images and index them in the most appropriate way.

The alt attribute is supposed to be an alternative to the image, usually its purpose must be declared. For example, an image of a warning sign should not have as an alt attribute the text “a triangle with a yellow background, black border and an exclamation mark”, but simply “Attention!” (Unless, of course, the purpose of the alt text is to actually show what the warning symbol looks like.
