AI Speedometer is our free tool that scores your website 0–100 on AI-citability — PageSpeed performance plus AI checks like bot access and llms.txt.
Every week, we talk to founders and marketers who want to know the same thing: *"Is my site even set up for AI?"*
**Part of our AI visibility score guide** — how the individual visibility metrics fit together.
They've heard about llms.txt. They've seen competitors mentioned in ChatGPT answers. They've read that AI bots use robots.txt. But there's no quick, free way to check all of it at once — until now.
Today we're launching AI Speedometer — a free tool that gives your website a single 0–100 AI Visibility Score in about 30 seconds, no sign-up required.
AI Speedometer combines two signal groups into one score:
AEO subscore (50%) — three binary checks specific to AI engine citability:
PageSpeed subscore (50%) — five scores from Google PageSpeed Insights:
Each AEO check is binary (100 or 0). The final score is: *composite = 0.5 × avg(AEO checks) + 0.5 × avg(PageSpeed scores)*.
| Score | Grade | What it means |
|---|---|---|
| 80–100 | A | Excellent — your site is well-optimized for AI citability |
| 65–79 | B | Good — minor gaps that are easy to fix |
| 50–64 | C | Average — meaningful improvements available |
| 35–49 | D | Poor — significant barriers to AI indexing |
| 0–34 | F | Critical — AI engines likely cannot cite your site |
If crawler access is 0: Check your robots.txt for `Disallow` rules covering GPTBot, ClaudeBot, PerplexityBot, or Google-Extended. If you have broad bot-blocking rules, add explicit `Allow` directives for these four bots.
If llms.txt is missing: Create a simple text file at `yourdomain.com/llms.txt`. At minimum, include your site name, a 1–2 sentence description, and links to your most important pages. The full spec is at llmstxt.org.
If HTML visibility is failing: Your page content is likely rendered entirely by JavaScript. This blocks AI bots that don't execute JS. Server-render your key content (product descriptions, FAQs, headings) so it's visible in the raw HTML response.
For the PageSpeed half: A low mobile performance score is the single biggest drag on the composite. Follow Google's Core Web Vitals recommendations — especially LCP and CLS.
AI Speedometer tells you whether your *technical setup* is AI-ready. TrueCite's full platform tells you whether AI engines are actually *recommending your brand* — and what to do when they're not.
TrueCite tracks your MentionShare (the percentage of AI answers that mention your brand) across 9 AI engines, detects competitor gaps, and generates ready-to-publish FAQ blocks and JSON-LD schema. 7-day free trial, no card required.
