Alt Tags: Incorrectly referenced, as they are actually attributes of the image tag. It displays a short text description of an image as you hover the mouse over it. The Alt tag is also used by search engines and screen readers to identify what the image is. If the image is not displayed for any reason, the text contained in the Alt tag will appear in its place. Use keywords in your Alt tags in a natural form to increase the relevance of your images to the text contained on the page.
