What is alt text and why does it matter? ▸
Alt text is the textual description of an image read by screen readers for users with visual impairments and shown when an image fails to load. It is also used by search engines to understand image content, making it essential for both accessibility compliance (WCAG) and image SEO ranking in Google Images.
How long should alt text be? ▸
Most sources recommend 125 characters or less, since this is where many screen readers truncate. The right length depends on the image's importance — a hero illustration needs a fuller description than a small icon. If detail is critical, use a longer caption nearby instead of inflating the alt.
Should I include keywords in alt text? ▸
Yes, but only when the keyword genuinely describes the image. Forcing keywords into every alt attribute is keyword stuffing and can trigger penalties. Google explicitly says alt text should describe the image accurately — relevant keywords will appear naturally when descriptions match image content.
What is decorative alt text? ▸
Purely decorative images (dividers, ornamental backgrounds, repeated icons) should use empty alt text (alt="") so screen readers skip them. Adding descriptions to decorative images creates noise for assistive technology users and adds nothing for SEO.
Should I write 'image of...' or 'picture of...'? ▸
No. Screen readers already announce 'image' before reading alt text, so starting with 'image of' produces 'image, image of...'. Jump straight to the description. The exception is when the format matters (e.g., 'Illustration of...' vs 'Photograph of...') to convey context the user might otherwise miss.
Are alt text and title attributes the same? ▸
No. Alt text is for accessibility and SEO. The title attribute creates a tooltip on hover and is mostly ignored by screen readers. Best practice is to write strong alt text and skip the title attribute unless it adds genuinely useful supplementary information.
