What does TrustSEO check?

Your site, from the outside, the way search engines, AI crawlers and AI agents fetch it. You get three 0–100 scores (SEO, AI Search and Agent Readiness), and every failed check comes with a plain-English fix.

Why don’t you track whether ChatGPT recommends me?

Because the answers change on every run. SparkToro ran the same prompts 2,961 times and got the same brand list less than 1 time in 100. We check the things that decide whether AI can reach and read you at all, and those give the same result every time.

Does llms.txt matter?

Less than you’ve heard. Ahrefs looked at 137,000 sites in 2026 and found 97% of llms.txt files never got a single request. We still check it, but we won’t tell you it’s why AI ignores you.

What is agent readiness?

AI agents like ChatGPT agent mode fetch pages live for a user. They skip JavaScript-heavy pages, get stopped by bot walls, and pick buttons by their accessible names. Agent Readiness checks all of that, plus markdown, MCP and API discovery.

How much does it cost?

Free gets you 2 full audits a month on one site, no card needed. Pro is $29 a month: 5 sites, 20 full audits a month, and weekly monitoring that emails you when a score drops. Cancel anytime, and there are no overage charges.

Do I need to install anything?

No. We only read public URLs: your pages, robots.txt, sitemap and a few well-known files. Nothing to install and no access to your servers.

Most sites don’t know AI can’t read them

Nothing breaks. No error shows up. You just stop getting mentioned.

Blocked at the firewall

Cloudflare has blocked AI crawlers by default since July 2025. Your robots.txt can say “allow” while your CDN answers 403.

Empty without JavaScript

GPTBot, ClaudeBot and PerplexityBot don’t run JavaScript. If your content only appears after it runs, they read a blank page.

Missing the basics

Google says AI Overviews have no extra requirements: a page has to be indexable first. A stray noindex or a bad canonical hides you everywhere.

48 checks. Three scores.

Every check is a real request to your site, the same one a crawler or agent makes. Each score is 0 to 100.

HTML weight421 KB of HTML
Fix: Trim the HTML payload. Inline data blobs and very large documents slow parsing for every crawler.
Render-blocking scripts1 blocking <script src> in <head>
Fix: Add defer or async to scripts in <head> so they don’t delay the content crawlers came to read.
Title tag63 characters
Fix: Keep the title between 15 and 60 characters, naming the brand and what it does.
Markdown for agentsAccept: text/markdown ignored
Fix: Serve a markdown version of each page. Agents read markdown with a fraction of the tokens HTML costs.

How it works

Paste your domain

No install, no script tag. We only read public URLs.

We fetch it like the bots do

robots.txt tested per crawler, pages fetched with agent user-agents, HTML read without running JavaScript.

Get three scores and the fixes

Every failed check says what’s wrong and exactly what to change, heaviest first.

Ship, re-run, compare

Audits are saved, so you can see which checks flipped after each deploy.

Same site, same result. Every time.

AI rank trackers ask ChatGPT the same question over and over and chart the noise. We check the things you can actually fix, and they don't change unless your site does.
