What is the use of alt attribute text? Alt attribute is a short piece of HTML code used to describe the pictures displayed on the page, but it is often ignored when developing and editing the content on the Web.
It is so inconspicuous that it doesn't seem to have any influence on ordinary users, but it does have a very important purpose: Web accessibility of screen readers: suppose we have a page with a large number of pictures, but none of them contain alt attribute text.
Users who surf with screen readers can only hear the word "image", which is of little use to them.
They only know that this is a picture and there is no other information.
If you have alt attribute text, screen readers can help visually impaired people "see" the content in the picture, so as to better understand the content of the page.
Some people say that a picture is worth a thousand words, but if there is no alt attribute text, these users will miss this thousand words.
If the picture can't be loaded, the text will be displayed: The Web looks absolutely reliable, just like new york, it never needs sleep, but the wrong connection does exist. If this happens, the picture often fails to load correctly and will be "damaged".
Alt text is a security measure, which will display the location of "damaged" pictures on the page and provide users with backup contents.
SEO performance: alt text of pictures also helps to improve SEO performance.
Although it can't make the search ranking of web pages higher, it is also a consideration to improve SEO performance.
After understanding these importance, I hope you can add correct alt text when developing and editing content.
However, trying to describe a large number of images in detail can be a daunting task, especially if you are pressed for time or busy with multiple projects.
If only there was a way to apply alternative text when uploading pictures! If only there was a way to check whether the page is missing alt attributes and automatically fill them in!
