AI Image Alt Text Generator

Alt text exists for accessibility first. A screen reader reads the alt attribute out loud when it encounters an image, so visually impaired users can understand what the picture shows. The SEO benefit is a side effect: Google reads the alt text to understand the image, which feeds both Google Images ranking and the relevance assessment of the page the image lives on. The keyword benefit is real but secondary to writing an accurate description.The two failure modes are empty alt and stuffed alt. Empty alt (alt="") is appropriate for decorative images that add nothing to the content, but a content image with empty alt throws away both the accessibility benefit and the SEO signal. Stuffed alt ("red running shoes Nike Pegasus 41 buy cheap free shipping") is the opposite problem: it hurts accessibility because the description is unreadable, and it hurts SEO because Google recognizes the keyword-stuffing pattern.Our generator takes an image description, the page topic, and the target keyword, then returns 3-5 alt text variants. Each one is concise (under 125 characters, the screen reader cutoff), describes what is actually in the image, and naturally incorporates the target keyword where it fits. The output is plain text you paste into the alt attribute. The generator also flags decorative images that should have empty alt instead.
