Hello @praveen c,
Some marketers now notice that Keyword Planner data displays ranged data instead of precise search volume. The ranges are wildly broad, with results like “100K–1M” and “1M+.
According to Google, “most” advertisers will see Keyword Planner data as usual. But AdWords users with a “lower monthly spend” could see limited data in the planner.
I guess such adwords account are called ranged account.
Though I am not sure about it
