Alt Text Best Practices
Keep it short, usually 1-2 sentences. Don’t overthink it.
Consider key elements of why you chose this image, instead of describing every little detail.
No need to say “image of” or “picture of.”
But, do say if it’s a logo, illustration, painting, or cartoon.
Don’t duplicate text that’s adjacent in the document or website.
End the alt text sentence with a period.
