Quick answer
Alt text is the short description attached to an image. It helps Google understand the image and helps people using screen readers.
What it means
Alt text is the short description attached to an image. It helps Google understand the image and helps people using screen readers. In normal terms, it is one small part of how Google and people understand your site.
Why it matters
It matters because images are invisible to search engines unless you describe them. Good alt text can help image search, accessibility and the general meaning of the page.
What to do about it
Describe the image in normal words. If the image is only decoration, leave the alt text empty. If it shows your product, place, team or work, say what is in it.
