ImgTheory – AI Alt Text Generator Stop losing search rankings to missing image descriptions. The problem Search engines can't see images — they rely entirely on alt text to understand what's on your pages. Yet most sites ship with missing alt attributes, generic filenames used as descriptions (IMG_4923.jpg), or one-word placeholders that tell crawlers nothing. The result: lost rankings, missed traffic, and WCAG accessibility failures — all for a problem that's fully automatable. ✨ What ImgTheory does ImgTheory scans any webpage, extracts every image, scores existing alt text for quality, and generates AI-powered replacements — context-aware, SEO-friendly, and under 125 characters.

One thing I learned while building ImgTheory:

Most website owners know ALT text is important.

Very few know how many images on their website are actually missing it.

The biggest challenge isn't fixing image SEO—it's discovering the issues in the first place.

A surprising pattern from early scans:

Many websites have excellent content, solid metadata, and decent page speed...

But image optimization is often completely overlooked.

Curious—how often do you check image SEO during an audit?
