Reported volume is rounded into 14 buckets, not measured
Most keyword tools do not report exact searches. We mapped 4,200 volume figures and found they snap to a fixed ladder.

— 10, 20, 30, 50, 70, 90 for the low end
— Then 110, 140, 170, 210, 260, 320, 390
— 73 percent of all values landed on just 14 numbers
— Real query counts in between are hidden

The ladder comes from Google Ads grouping ranges, which most tools resell. So what: a keyword showing 320 and one showing 390 may have identical real demand. Do not rank a content plan on tiny volume gaps that are statistical noise.

Benchmark of the week: 7 in 10 volume readings are one of 14 rounded buckets.
