Ready combines robots policy, a bounded synthetic User-Agent fetch, indexability, and snippet eligibility. Synthetic probes do not prove vendor-origin traffic. Purple preference states are training or data-use choices and do not lower the AEO score.
The image refreshes from FreeScan after a completed rescan. Clicking it always opens the newest public report saved for this exact scanned URL.
Scan evidence is included as untrusted data. The implementation brief instructs agents to verify findings before editing and to avoid destructive or speculative changes.
