Data sources: The Visio Intent Index aggregates 38 buying-intent signals from the Visio Auto platform — brochure downloads, finance calculator usage, test-drive requests, trade-in valuations, social engagement, repo risk and life-event triggers across thousands of SA buyers.
K-anonymity: Any cell (region × brand × segment × signal) with fewer than 5 records is hidden to protect individual identifiability under POPIA.
Normalisation: Raw signal counts are log-scaled and capped at 100, then normalised against the rolling 12-week median.
Update cadence: Free public Index updates weekly (Monday 06:00 SAST). Subscribers get daily or real-time depending on tier.
Provenance: Every data point is traceable to its source signal in the underlying Supabase store. No fabricated data is ever published.
