The range is the distance between the smallest and the largest value in a set — the full span from the minimum observed value to the maximum observed value.

What it means in RankGear
When RankGear explains the strategy behind a factor, the range tells you how far apart the ranking pages are on that measure. If the competing set carries between 8 and 34 internal links, the range is that whole 8-to-34 stretch — the lowest and highest values the top results actually reached. It sits alongside the average and the spread in a strategic explanation to answer a different question: not “what is typical” but “how much room is there between the leanest and the heaviest page.” A narrow range says the competitors cluster tightly on that factor; a wide one says they scatter, and a single target will fit some of them and miss others.
How to interpret it
Read the range as a boundary line, not a goal. It marks the extremes, so both ends can be set by one unusual page — a lone outlier at either the top or the bottom stretches the range without telling you where the bulk of the results sit. Always weigh it against the sample size and the average: a wide range across only a handful of pages is fragile, and a value that lands inside the range is not automatically a safe target, because the middle of the pack may be nowhere near the midpoint of the two extremes. Check, too, whether the boundary values were genuinely measured, missing, or a true zero, since a zero minimum reads very differently from a factor that simply wasn’t recorded.
| Set of values | Range | What it tells you |
|---|---|---|
| 12 · 14 · 15 · 16 | 12–16 (span 4) | Tight range — competitors agree, a clear target |
| 3 · 14 · 15 · 41 | 3–41 (span 38) | Wide range from two outliers — the ends mislead |
Example
Suppose a strategic explanation for a keyword shows the top pages using a heading count with a range of 6 to 22. That span alone doesn’t tell you to aim for 14. If most of those pages sit between 6 and 10 and one long guide reaches 22, the high end of the range is a single outlier, and building toward the middle would overshoot what actually competes. Two keyword runs can report the same average heading count yet very different ranges, and the wider one warns you that a practical target is harder to pin down.
Important considerations
- The range is defined entirely by two points — the minimum and the maximum — so it is the statistic most easily distorted by a single outlier at either end.
- It describes spread but not shape; a range says nothing about how the values in between are distributed, which is why it reads best beside the average and the sample size.
- Small SERP samples are unstable, and a range built from only a few results can swing between runs without anything meaningful changing.
- A range drawn from provider data is a comparative indicator of what ranking pages look like, not a score Google assigns, and matching it is an association rather than a cause of ranking.
