Why is the interest value always between 0 and 100 instead of a real search count?
Google Trends does not report absolute search volume. It reports a normalized index that scales the popularity of a term relative to its own peak within the selected timeframe and location. The value 100 marks the point of highest interest, 50 means roughly half that interest, and 0 means there was too little data to report. Because the numbers are relative, they are meant for comparing keywords, tracking seasonality, and spotting rising topics — not for estimating how many people searched. For absolute search-volume estimates, see the Google Keyword Planner data reference; for real impression and click counts on owned properties, see the Google Search Console data reference.Why does the same keyword show different numbers over different date ranges?
Google Trends re-normalizes the index for every request. The peak within the requested window is set to 100, and every other point is scaled against that peak. Changing the timeframe changes which point is the peak, so the same keyword can show different index values in a 7-day view, a 90-day view, and a 12-month view. This is expected behavior, not a data error. To compare values reliably, keep the timeframe fixed across the widgets being compared.Why can only 5 keywords be compared at once?
Google Trends limits a single comparison to 5 keywords, and the connector enforces the same cap. A query with more than 5 keywords is rejected when the data source is set up. To track more terms, additional Google Trends data sources can be connected, each with its own set of up to 5 keywords. Keep in mind that indexes are only normalized against the keywords inside the same query, so terms split across separate data sources are not directly comparable to one another.Why do some rows come back empty?
A few expected conditions produce empty or missing rows. Google Trends suppresses data for terms whose search volume falls below its internal reporting threshold, so low-volume or very specific keywords can return nothing. Google Trends also has no official public API, so interest data is gathered from the public Trends service and heavy or repeated querying can be rate-limited, which can leave gaps until the next successful refresh. The most recent day or two may also read low or blank while Trends still treats that period as incomplete. Broadening the keyword, widening the date range, or checking again after the next refresh usually resolves it.Which locations are supported?
Google Trends interest can be scoped to Worldwide or to a specific country, selected during setup. When no location is chosen, results default to Worldwide. Interest is always normalized within the chosen scope, so a keyword’s index in one country cannot be read as more or less popular than the same keyword in another country — each is scaled against its own local peak.
