Using the alt attribute to describe the filename of the image
One common mistake is to use the alt attribute to describe the filename of the image. For example, the alt attribute for the image "image.jpg" might be "image". This is not a good practice because it does not provide any useful information to users who cannot see the image. A better alt attribute for this image would be "A photo of a cat.".

This additional information is not necessary for understanding the content of the image, and it can make it more difficult for screen readers to convey the image's content to visually impaired users.

By avoiding these common mistakes, you can ensure that your alt attributes are effective and informative, improving the accessibility and SEO of your website.
