Technical standards and proof
Know what the quality standard protects—and what it cannot promise.
Agreed first-party pages are not accepted until they reach the recorded 100/100 Lighthouse SEO and 3/3 Agentic Browsing standard, or in-scope issues are remediated. That protects technical quality at handover; it does not promise a search ranking or commercial outcome.

What this result does—and does not—say
It supports
- The scoped 100/100 promise is a remediation commitment on agreed first-party pages under recorded handover conditions.
- The named production page met the recorded lab results under three comparable runs.
- The implementation produced no measured layout shift in that sample.
- The complete JSON reports and checksums are retained in the project evidence archive.
It does not support
- It does not control whether Google or an AI platform ranks, cites or includes the business.
- It is not field data from every device, network or visitor.
- It does not guarantee rankings, enquiries, bookings or revenue.
- It does not automatically describe a future client website or third-party booking engine.
The proof should match the promise you are being asked to trust.
- Handover acceptance
- Named first-party pages, recorded test conditions, the agreed SEO and agentic audit, and remediation before acceptance.
- Performance
- Comparable production tests plus field data when sufficient traffic becomes available.
- Search visibility
- Source, query, market, device and date. Third-party volume remains an estimate.
- Business outcomes
- A defined lead or booking, an attribution boundary, a date range and client permission.
- Demonstrations
- The exact label ‘Concept demonstration — not client work’ and no implication of real commercial results.
