SEO Benchmark Data: What Crawled Websites Technically Show
This page summarizes the currently available Seitenreport benchmark data. It shows which technical SEO signals appear in the database, how countries and CMS are distributed and where the boundaries of the sample lie.
The evaluation is to be understood as a growing database. For small segments, values are more likely to be directional signals than a representative market study. It is precisely this transparency that makes the benchmark data usable for SEO decisions.

Methodology and limits
Current measurement basis
The live benchmark analyzes up to 10 important URLs from sitemap or internal link selection. The baselines are also built on this sample logic after the next batch crawl.
Why make sense?
Several URLs show patterns across page types: Meta data, H1, canonicals, ALT texts and structured data are more realistically classified.
Limit of V1
The sample does not replace a full analysis of all URLs. It is a fast website average and shows much more than a pure homepage moment recording.
