Alt Text (Alternative text)

What is Alt Text (Alternative text) ?

А word or a phrase that informs users about the content type of the linked image. Alt characteristics, alt descriptions, and alt tags are all terms that refer to the same thing (which is technically incorrect). Visually impaired individuals can utilize screen readers to hear an alt attribute to understand better an on-page image, which is the primary use of alternative text. A blank space will be displayed in place of an image if one can't be loaded due to technical reasons. Search engine crawlers benefit from it because it gives them greater image context/descriptions, making image indexing easier. To inform website visitors about the nature or content of an image, use alt text (alternative text), which is a word or phrase supplied as an attribute in an HTML (Hypertext Markup Language) document.

The alternative text appears in place of the image in a white box. When an image link is unavailable due to a damaged or altered URL or other reason, alt text comes in handy. To create an alt attribute, type alt= and enter the text you want to use in the alternative text box, enclosed in quotation marks. For example, a picture of rising water during a cyclone might have the attribute alt="Storm Surge" in the HTML image element. When you hover your mouse pointer over an image with an alt tag, the image's alternative text will appear in a little box below your arrow. When selecting alt text, be sure to use as few words as possible to convey as much information about the image as feasible to readers.

As photos increase smaller in size, this factor becomes more essential. If the alt text is too long, the picture rectangle may not accommodate it (which is the same size as the image would be if it were visible). For example, alt text would be redundant for bullet links with external text labels. Instead of having a space between the quotations, the alt text can either be "alt=" ") or "alt=" (which puts two quotes immediately next to each other). Even if no alt boxes are required, alt attributes should always be included in image tags.

To prevent a default character sequence showing the picture's URL from appearing when the viewer hovers the cursor over the image, the Web page creator should enter a blank alt attribute into the image tag. Use relevant keywords in the alt text of your photos to boost your website's search engine rankings (SEO). On the other hand, keyword stuffing is discouraged on the Web, as it is in other places where text is used. This technique is not only unethical, but it is also ineffective, according to Google.
