Response Fields

Field	Type	Description
keyword	string	The keyword queried
search_volume	integer \| null	Average monthly search volume for the location; null means the source has no data (not zero searches)
cpc	float \| null	Average cost-per-click in USD
competition	float \| null	Competition index (0-1)
competition_level	string	HIGH, MEDIUM, or LOW
monthly_searches	array	12-month breakdown of search volume by month
location_used	string	Canonical location the volumes are actually scoped to
location_alternatives	array	Sibling geo entities in the same state (e.g. "Hamilton Township" alongside "Hamilton") — distinct entities whose volumes can differ 3-5x; re-query with the alternative name for its numbers
volume_scope	string	"local" (city/state-level data) or "country" (national numbers — used when no local data exists)
data_source	string	"google_ads" (localized) or "labs" (country-level fallback)

Notes

Volumes are location-specific — a keyword can have 2,400 searches in Denver but 150,000 nationally. Check volume_scope to confirm the numbers are local.
When no local data exists the API falls back to country-level numbers and labels them (volume_scope: "country") instead of passing them off as local.
Send up to 1,000 keywords in a single request for bulk analysis.
CPC data reflects Google Ads pricing and indicates commercial intent.
