Aggregated, anonymised audit data from active engagements. No claims, no derivations from study summaries — these are the numbers I see in mandates myself.
The figures come from a rolling cohort of 500+ enterprise domains in DACH, the EU and the US. All data is anonymised at industry level; individual domains cannot be identified through the aggregation. The purpose: market-wide orientation for operators — not marketing.
Update cadence: monthly, in the first week. The data points below reflect the latest update.

Correlation
Citation rate in Perplexity rises disproportionately from DA 60 upwards. Threshold for relevant citation presence: ≥ DA 40. Reason: authority is one of four retrieval-score components, weighted heavily.
