- Alt-text descriptions help search engines find images when people confine their searches to images.
- If the image doesn’t load, its alt-text description will appear in its place.
- Mobile users may not see your images when browsing your site on their handhelds.
- Visually impaired visitors to your site who use screen readers will hear the alt text accompanying your image.
A few tips to keep in mind:
- Write alt text that is unique and specific to the image.
- Limit your alt text to a short sentence or phrase that includes keywords
- Make your alt text meaningful. Rather than merely write something like “Dog,” write "German shepherd watch dog guarding the junk yard."
