- Add the page topic or target keyword for context.
- Copy the generated alt attributes or the full <img> snippets.
Frequently asked questions
How long should alt text be?
Under 125 characters — descriptive but concise. Do not stuff keywords.
Should every image have alt text?
Every meaningful image, yes. Purely decorative images should use an empty alt="" attribute.
