How does your AI readiness compare?
Enter your domain and up to three competitors. This checker fetches each homepage, scores its on-page answer-engine readiness, and ranks them.
Why on-page readiness matters
AI answers name brands they can read and trust
Share of voice in AI answers is how often each brand gets named when people ask assistants for options. Before an assistant can name you, it has to be able to read your site, understand who you are, and extract clean answers — so the brand with the stronger on-page foundation is more eligible to be named.
This checker scores that foundation for you and your competitors from live HTML and ranks you, so you can see where you trail before you measure actual mentions.
What puts you behind a competitor
- Thin homepage content an assistant can't summarize
- No Organization structured data to identify you
- No lists, tables, or question-led sections to quote
- A rival with a cleaner setup gets named instead

What does the AI share of voice checker do?
It fetches your homepage and up to three competitors' homepages, scores each one's on-page answer-engine readiness deterministically — content depth, a title, Organization structured data, lists and tables, and question headings — and ranks them side by side so you see who's best positioned to be named by AI answers.
Does it measure my real share of voice in AI answers?
No — and it never pretends to. Your actual share of voice (how often each brand is named in ChatGPT, Perplexity, Gemini, or Google AI answers) needs live queries across those engines, which is the paid AEOMaster audit. This free checker compares on-page readiness, which is what makes a brand eligible to be named.
How are the scores and ranking calculated?
Each domain's score is a transparent average of five equally-weighted on-page signals, every one a real structural fact of that site's homepage. It's deterministic — the same pages always produce the same ranking. It reflects on-page readiness, not live AI mentions.
Which pages does it compare?
It compares homepages — the most representative page for site-wide readiness. Enter your domain plus up to three competitor domains; each one's homepage is fetched and scored. The full AEOMaster audit compares across pages and the live AI answers.
Does ranking first mean AI names me most?
Being better positioned on-page makes you more eligible to be named, but actual mentions also depend on authority, evidence, and relevance to each prompt. The full AEOMaster audit measures how often AI answers actually name you versus each competitor, and for which prompts.
