Isn't this just SEO?
No. SEO measures what Google sees. Agent readiness is whether AI agents like ChatGPT, Claude and Perplexity can find, read and use your site. Most SEO reports don't test that, so the two work side by side.
Do AI crawlers run JavaScript?
Most don't. A study of crawler traffic by Vercel and MERJ found that the crawlers from OpenAI, Anthropic and Perplexity fetch pages without running JavaScript (Dec 2024). Anything your site loads with JavaScript can be missing from what they read.
Do I need an llms.txt file?
No. It's a small signal. Google says its AI features need no special files, so llms.txt never decides a score on its own.
Can I block AI training but still appear in AI answers?
Yes. Training crawlers and search crawlers have separate names, so robots.txt can treat them differently. You can block GPTBot, which collects training data for OpenAI, and allow OAI-SearchBot, which fetches pages for ChatGPT search.
How long does the audit take?
7 days. Every layer is scored, every lost point comes with its evidence, and each finding comes with a fix.
Is Code4X self-serve software?
No. Code4X is an engineer-led service. Prompt, our free check, runs on its own. Every other plan has an engineer on it, and you approve each change in a private dashboard.
Will you change my website without asking?
No. Every fix goes to staging, is re-audited, and waits for a person on your team to approve it before it goes live.
