Accessibility Pro Tip: When to use an empty alt attribute (alt="")

If an image is purely decorative (such as visual background dividers, decorative swirls, or spacer graphics), do not write descriptive text. Instead, provide an empty attribute alt="" so screen readers ignore it rather than reading the raw file name.

SEO Impact & Strategy

Why Accessible Image Alt Text Matters

Alt text (alternative text) serves two critical purposes: web accessibility and visual search ranking. Visually impaired users rely on screen readers to read alt attributes aloud, making descriptive alt text essential for ADA and WCAG 2.1 compliance. Additionally, search engine crawlers cannot 'see' image pixels; they rely on alt attributes to understand image subject matter and index images into Google Image search. Keeping alt text under 125 characters prevents screen reader truncation while ensuring natural, spam-free keyword relevance.
