⚠ Fragile visibility. Only Perplexity names them; ChatGPT and Gemini never do. If Perplexity changes its mind, they disappear from AI results.
Can AI read their site?
Probe stability: 0 signals disagreed between the two passes.
What to fix
- Make sure the site answers ordinary HTTP clients, not just browsers; a WAF that blocks agents also blocks assistants.
- Publish a real
/llms.txtthat summarizes the business for AI agents. - State an explicit AI crawler policy in
robots.txtfor GPTBot, ClaudeBot, Google-Extended and PerplexityBot. - Serve a valid XML sitemap and declare it in
robots.txt. - Add schema.org
LocalBusinessJSON-LD so machines can read hours, service area and contact details. - Optional: publish a verified MCP card at
/.well-known/mcp.jsonif agents should transact directly.
History
This history starts here. August 2026 is the baseline — every future edition stacks on top of it, and a dated record like this cannot be created after the fact.

Monthly readout; scorecard stays free
$149 / month
Free move list: email when this shop's stamp changes. Watch ($149/mo) is the monthly readout beside it — different product. Payment never touches the grade.
- Told when a model starts or stops naming them
- Machine-readability changes re-checked each edition
- Payment never touches the grade
$149 a month against a four-figure job. If one readout helps you win back a single job a year — or hold one you were about to lose to a shop the assistants like better — it has paid for itself. The scorecard stays free either way.
This scorecard is free and it is not for sale. We do not sell the fix, and no payment moves this number — not from this business, not from whoever markets it. Send corrections with evidence to watch@lodestarindex.com.
