What is Alt Text?
Alternative text (alt text) is a description of an image within an HTML tag. It serves two vital purposes: it helps visually impaired users understand the image via screen readers, and it helps search engines index the image correctly.
How to Write Great Alt Text
Bad alt text is better than no alt text, but great alt text is what wins rankings.
Bad:
alt="dog"
Better:
alt="golden retriever puppy"
Best:
alt="Golden retriever puppy running on a green grass field with a ball"
