Qualified sample
Only completed checks with at least 75% data coverage and six usable signals; at most one run is counted per domain.
The Sendequelle landscape report aggregates explicitly requested public one-off checks into an anonymised monthly analysis. It explains the sample, selection bias and measurement limits rather than rating individual domains.
Published monthly reports remain available with their measurement period and methodology. Each chart describes the sample examined.
Only completed checks with at least 75% data coverage and six usable signals; at most one run is counted per domain.
Only monthly aggregates are stored and published in the report. Domain names, requesters, IPs, organisations and private data are excluded.
Sample size, confidence intervals, suppressed small cells and selection bias are shown alongside the results.
Reports are published after the end of the month and only when the sample is sufficient. The methodology and quality criteria remain available in the meantime.
