Why This Tool Exists

Useful diagnostics should show the evidence—not just a score.

Each Avenzo tool is designed around observable data, explicit assumptions and actionable next steps. Where an external data source is unavailable, the report says so instead of inventing a metric.

Real signals

HTTP responses, page markup, structured data, sitemaps, links, headers and user-entered business assumptions.

Explainable results

Warnings describe what was found, why it matters and what should be checked or changed next.

Full-audit path

When the site is larger than the free sample, the report makes the limit explicit and points to a deeper Avenzo audit.
