About Vizibly
Machines still need words to understand your images
Modern engines can look at a picture — but they still lean on words to understand it, file it, and connect it to the rest of the web. Vizibly makes sure those words are there for every image on your site.
The problem
Most images ship without the words machines rely on
In its 2026 survey of the top one million home pages, WebAIM found that over half had images with missing alternative text (WebAIM, 2026). No alt text, often no descriptive filename, no structured data — nothing for a search engine or an AI model to hold onto.
When that context is missing, engines are left to guess what an image shows — and often can't index it meaningfully. Vizibly closes that gap: it audits every image on a page, scores it on SEO and GEO signals, and generates the alt text, captions, schema, and LLMs.txt entry it's missing.
The story
Built in the open, by one person
Vizibly is built after hours, alongside a full-time job. No team, no office, no outside funding. Just a 15-day build-and-ship challenge, documented daily on X (@theyole_).
Principles
The principles behind every audit and optimization
Transparency first
Every score is explainable — and the copy on this site is held to the same bar. When the compression demo was measured, the number was corrected downward. That's the policy working.
Speed matters
Full page audits in under 60 seconds. AI metadata generation in one click. No waiting around.
Your data stays yours
Scans are read-only — your site is never modified. The audit results and images you upload are stored so you can optimize them, and you can delete them anytime.
