Rigorous Standards

Methodological principles of the AuditaSite Observatory

Empirical

Deterministic Measurement

All data originates from automated probes executed directly against live production servers. No opaque algorithmic estimates or subjective surveys are used.

User-Agents

Real Crawler Emulation

Server responses are analyzed under official HTTP User-Agents (Googlebot, OAI-SearchBot, PerplexityBot) and compared directly against headless Chromium DOM rendering.

Open Data

Open Data & Reproducibility

Datasets for each release are published in standard open formats (CSV and JSON) with Schema.org Dataset markup so journalists, researchers, and engineers can verify or extend findings.

How can media outlets cite Observatory studies?

Any news organization or technical publication may freely cite the findings with proper attribution: “Data from AuditaSite Web Observatory (auditasite.com)” or by linking directly to the corresponding study URL.

Who authors and oversees the research?

The Observatory was conceived and developed by Cristina Bouda, technical SEO, WPO, and AI search visibility (GEO) consultant based in Málaga, Spain (cristinabouda.com).

Can specific industries or website cohorts be proposed for future studies?

Yes. Domain samples or specific vertical sectors can be submitted via the contact page for consideration in upcoming public benchmark reports.
