SFR (Search Frequency Rank)
Amazon Brand Analytics' rank of every search term by how often it was searched — 1 is the most-searched query on Amazon that period. It is a rank, not a volume: the gap between #500 and #5,000 is enormous.
SFR is the spine of ABA's Top Search Terms report: every query ranked by search frequency for the chosen period (day, week, month, quarter). Amazon does not publish absolute search counts, so SFR is the official signal of relative demand — third-party tools like Helium 10 model their volume estimates on top of it.
Two operator uses. First, seasonality truth: watch a term's SFR trajectory across weeks instead of trusting a single snapshot. Second, keyword prioritization: a term moving from SFR 80,000 to 20,000 is demand arriving; a stable SFR with your click share falling is a competitor problem, not a demand problem. Because it is a rank, always compare like periods — weekly SFR against weekly SFR.
The numbers
- Rank 1 = the most-searched term on Amazon for the period; the scale is exponential — low-rank tails represent tiny fractions of head-term demand.
- Reported in ABA Top Search Terms with daily/weekly/monthly/quarterly grains, alongside the top-3 clicked products per query.
- No absolute volumes: SFR is ordinal. Cross-period comparisons only make sense at the same grain.
