Most AI crawlers don't run JavaScript. If your prices load after the page opens, ChatGPT, Claude and Perplexity never see them.
Real sites, measured on their public pages. We show how ready each one is. What needs fixing stays private, between our engineers and the site's owner.
Step 1
We go through your scan result and what matters to your business, then scope the work.
Step 2
Your domain and the pages we check, agreed with you before we start.
Step 3
Your team signs in to see results as they land, and to approve each change.
Step 4
Every layer scored, the evidence for each lost point, and a fix for each. 5 working days.
Step 5
Each approved fix goes to staging, is re-audited, then goes live. On the retainer, we re-audit monthly.
Your starting point: a score and your top 3 findings.

Read moreNo. 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.
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.
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.
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.
