What makes AI visibility data decision-grade rather than directional?
The IAB splits measurement into two tiers. Directional data answers "is visibility broadly up or down" and is fine for early signal and internal briefings. Decision-grade data supports budget allocation and provider selection, and has to clear stated thresholds.
The framework treats fewer than 50 queries per measurement program as exploratory rather than even directional, because below that floor a category cannot be characterized at all.
The failure mode is not using directional data. It is treating directional data as decision-grade without noticing the gap.
| Criterion | Directional | Decision-grade |
|---|---|---|
| Query volume | Covers the category; under 50 is exploratory | Large, with subcategory coverage |
| Intent coverage | At least two intent types | All four, segmentable |
| Testing cadence | Monthly or quarterly | Weekly or more often |
| Reproducibility | Variation documented | Stated range within 7 days |
| Platform coverage | Disclosed | Reported per platform, not blended |
