The importance of alt tags
An ALT tag, also known as "alt attribute" and "alt description," is an HTML attribute applied to image tags, to describe an image. Search Engines (like Google), and Screenreaders (for Visually impaired people), don't know what an image looks like unless you tell them.
If you have ever done a search on Google images, you are actually doing a search for the ALT tag assigned to the image. If there is no ALT tag, your image is not going to come up in the search results.
Visually impaired people use the Internet, but they can't see it - they use screenreaders that read the contents of the page to them out load. A screenreader has no idea what an image looks like - not unless you tell it. This is where an image ALT tag comes in. You describe the image in the ALT tag, and a screenreader will read out this description.
How to add them
Simply insert a description into the Image ALT tag field when an image is uploaded to the editor. Clicking edit on an image that has already been placed on your website will give you this option again. Watch the video above to see exactly how this is done.
