Definition
Alt attributes, often called alt text, are text descriptions added to images in HTML to help screen readers and to provide context when images do not load.
Key Takeaways
- Alt text improves accessibility and can improve clarity for users with assistive technology.
- Alt text should describe the image purpose, not stuff keywords.
- For treatment sites, alt text should be respectful and avoid sensitive details.
Why It Matters for Treatment and Behavioral Health
Accessibility matters most on pages where families are trying to act quickly, like contact and program pages. Good alt text supports usability and professionalism.
Treatment Lens: What to Write
Describe what the image shows in plain language. For staff photos, a simple descriptor is enough. Avoid including sensitive patient details or unnecessary labeling.
SEO Note
Alt text can support image understanding, but its primary job is accessibility. Treat it as helpful description, not a ranking hack.
Common Mistakes
- Leaving alt text blank on important images that convey meaning.
- Stuffing keywords into alt text.
- Writing overly long descriptions that do not help users.
