The HTML code contains a wide number of tags. These tags share a wider number of attributes that can take different values. Among them, the “alt” attribute is one important one that has been misused and underestimated. In fact, it is not an obsolete attribute that should not be used; it is an important factor that can save a website reputation and reduce the bouncing rate of users. Therefore, the impact of this attribute is important to use positively. But first, let’s learn about this attribute and how it is used.

The “alt” attribute takes a text as a value. The text will be displayed instead of a broken image thumbnail.


<img src=”the URL” alt=”descriptive text”> </div>


This attribute allows the browser to use default values when the primary component can’t be found; this situation is frequent when the browser is not fully configured or does not support the implemented CSS style.

This attribute is preferably used with the IMG, AREA, and INPUT tags.

Nowadays, search engines display research results pages with exclusively of images. If the image doesn’t contain an “alt” attribute, the search engine will not be able to reference it and therefore it has low chance to be displayed in search results.
