Compare keyword popularity by region

No. In each keyword’s regional-interest records, 100 is that keyword’s highest popularity reference across the relevant locations. A value of 50 is relative to that reference. Because each keyword has its own reference, two keywords both scoring 100 do not establish equal search demand.

Use the returned within-region comparison when available, and match its values to the accompanying keyword order. Do not compare the two separately normalized per-word scores as if they shared one reference. Keep the reported comparison values; do not assume they sum to 100 or turn them into audience percentages.

It uses the highest popularity across the submitted words and relevant locations as a shared reference of 100. This lets you read those values on one common scale. The supplier labels this collection absolute_items, but its values remain relative indicators, not absolute search counts.

The supplier defines zero as insufficient data, which does not prove zero searches. A request with one keyword has no two-keyword comparison and returns that comparison as null. Other missing values or regions are unavailable information. Keep unknown geographic identifiers empty rather than inventing them.

It summarizes relative regional interest over the supplied date interval, without a weekly or daily trend line. Coverage and data age can vary. A returned UTC timestamp records receipt of the result, rather than the collection time of every regional value. Use the summary as modeled context, not a current market-size estimate.
