Guide to writing effective alt text for accessibility and SEO

By PulseAugur Editorial · [1 sources] ·

This article provides guidance on writing effective alt text for images, emphasizing its dual benefit for screen readers and search engines. The author recommends using empty alt attributes (alt="") for purely decorative images to avoid unnecessary narration by screen readers, while informative images require descriptive text. The advice includes keeping alt text concise, ideally between 8 and 15 words, avoiding redundant phrases like "image of," and focusing on the image's informational takeaway rather than keyword stuffing.
