Why rankings change every day
A keyword changes position by three or more places between two checks on different days, with no site change in between. A change that holds for fewer than 14 days is noise. A change that holds for 14 days or more is a signal.
What This Is
A keyword changes position by three or more places between two checks on different days, with no site change in between. A change that holds for fewer than 14 days is noise. A change that holds for 14 days or more is a signal.
Before you check
Compare the same query on the same device in the same location.
Have 90 days or more of position data for the query.
Know a single check is one snapshot, not a trend.
Diagnostic tree
Run the checks in order. Each check ends in a resolution or the next check.
Check 1. Where did each reading come from?
How: identify the source of each reading. Was it a browser search, or a rank tracker set to one device and one location?
Why: a browser result is shaped by your search history, your location and your device. A tracker reads one fixed device and one fixed location. The two will not agree, and neither is wrong.
If either reading came from a browser search, go to Resolution A. If both came from the same tracker, go to Check 2.
Check 2. Do the tracker and Search Console agree?
How: compare the tracker’s position for the query with the Search Console average position for the same query over 28 days.
Why: Search Console average position blends many devices, locations and searches. A tracker checks one device and one location. A gap of five places or less between the two is normal.
If the two differ by more than five places, go to Resolution B. If they agree within five places, go to Check 3.
Check 3. Did clicks move with the position?
How: Search Console, Performance, Search results, Queries tab. Read clicks and position for the query over 28 days.
Why: a position change that matters changes clicks. A position change with flat clicks is churn.
If clicks changed by 10% or more in the same direction, go to Check 4. If clicks changed by less than 10%, go to Resolution C.
Check 4. Did the change hold for 14 days or more?
How: plot the query position over the last 90 days in Search Console. Read the shape.
Why: day-to-day churn reverts within a week. A change that holds for 14 days or more is a real shift, not noise.
If the position held for 14 days or more, go to Resolution D. If it reverted within 7 days, go to Resolution E.
Resolutions
Resolution | Condition | Action |
|---|---|---|
A. Personalized reading | One reading came from a browser search | Use one tracker, one device, one location. Check once a week, not daily |
B. Tracker and Search Console disagree | Gap of more than five places between tracker and Search Console | Trust Search Console. Watch the position-band report monthly |
C. No click impact | Position changed, clicks flat | No action. Watch the 90-day trend, not the daily number |
D. Real shift | Position held for 14 days or more | Check the change log and the Google update calendar for a cause |
E. Churn | Position reverted within 7 days | No action. Watch the 90-day trend and the position-band report, not the daily number |
The position-band report
Group queries into bands: 1 to 3, 4 to 10, 11 to 20, and 21 or worse. Count the queries in each band. Watch the counts month over month over 90 days. A daily position is noise. The band counts are the trend.
When to escalate
Escalate when a query that carries clicks falls five or more positions and holds that loss for 14 days or more.
