Technical SEO statistics are easy to overgeneralize because the same metric can represent different operating conditions across sites. A crawl ratio on a publisher, a product catalog, and a documentation site may have different denominators, different intentional exclusions, and different update patterns. Before citing a figure, identify the measured population, the observation period, the data source, and whether the metric describes a public threshold, an external study, or an internal observation.
The source material combines public documentation, web-performance datasets, practitioner observations, and patterns seen in prior engagements. Where the source JSON does not include an original source URL, this rewrite does not elevate an attributed figure into a verified third-party statistic. Such figures are preserved as historical or directional source material that still requires source reconciliation before external citation.
For Core Web Vitals, public field datasets can define how a metric is measured and how current thresholds are classified. For crawl and indexation, first-party Search Console data and a fresh site crawl are usually more decision-useful than a broad external average because they describe the actual URLs, directives, canonicals, and rendering behavior of the site being audited.
Interpretation should also separate correlation from causation. A site with stronger indexation coverage may also have better internal linking, fewer duplicate URLs, more stable hosting, or more differentiated content. A benchmark can indicate where to investigate, but it does not identify the cause without page-level and template-level evidence.
Use this page as a calibration reference, not as a guarantee. Preserve the original metric definition, sample boundary, and period when those are known. When they are not known from the source JSON, state the limitation and validate the decision against your own crawl, Search Console, field-performance, and analytics data.
