Image alt text
All images have alt text
What this check looks at
Optia checks that every meaningful <img> on the page has a descriptive alt attribute.
Why it matters
Alt text is how screen-reader users perceive images and how search engines index them — it powers image search and adds topical context to the page. Missing alt text is simultaneously an accessibility failure and a lost ranking opportunity.
How to fix it
- Describe what the image shows in a specific phrase under ~125 characters.
- Include the target keyword only where it genuinely describes the image.
- Use
alt=""(empty, not missing) for purely decorative images so assistive tech skips them.
Fix it with Optia: Optia generates descriptive, keyword-aware alt text per image — review each suggestion against the actual image before applying.
