what does the 'vs 7d ago' change on my score mean?
Updated June 30, 2026 · Reviewed by Mack Grenfell · Asked 41 times
The change figure compares your latest score against your most recent report from before the chosen window. "vs 7d ago" compares today against the closest report older than seven days, not exactly seven days ago. You can switch the window to 7, 14, 30, or 90 days.
How the comparison is built
- It finds the most recent prior report beyond the window you picked, then shows the point change and percentage change against it.
- It is report-to-report, so the exact dates depend on when reports landed, not a fixed calendar offset.
The edge cases that confuse people
- **No prior data:** the change shows as null with the label "No prior data."
- **Was 0, now above 0:** the change is null (not infinity) with the label "New data," because a jump from zero is not a meaningful percentage.
- **Both periods are 0:** the change is 0.
If a number looks blank rather than zero, that is usually one of the cases above, not a bug. Live-retrieval engines like Perplexity and AI Overviews move fastest, so short windows show movement there first.
