How to read this preview
This technology cohort includes domains with a successful stored scan and a detailed observation of this technology scoring at least 70. Country previews additionally require at least five meaningful technologies and a geography score of at least 70. Rows show when X-Clacks-Overhead was observed; a dated detection is not a live verification. Rule scores summarize fingerprint evidence and are not measured accuracy percentages. The public preview and paid database use different eligibility rules.
Open a website report, check the observation dates and relevant signals, then save matching domains in the database. Pro includes CSV lead-list exports and 500 monthly enrichment credits; Business includes 5,000. Enrichment does not provide contact details or buying intent.
