Trackers disagree: likely noise, not a broad update
2 of 6 live trackers sit within 2 points of the consensus. One or two trackers are hot while the rest stay calm. Likely a niche or single-tool move, not a site-wide update.
What to do
- Only some trackers are hot. Check the tracker cards: if the hot one follows your niche or country, take it seriously.
- Otherwise treat it as noise and carry on as normal.

What is Google search volatility?
Google search volatility is a measure of how much search engine results pages (SERPs) change from one day to the next. Google continuously refines its ranking systems — through major core updates, targeted spam updates, and countless smaller adjustments — and each change can reshuffle which pages rank where. A SERP volatility tracker quantifies that movement: the more rankings shift across a tracked set of keywords, the higher the volatility reading.
No single tracker tells the whole story. Each tool watches a different set of keywords, in different countries and categories, and reports on its own scale. This Google search volatility aggregator brings the major public trackers together, normalizes every reading to one shared 0–10 scale, and computes a single consensus — so you can see the broad picture at a glance instead of checking a dozen tools.
How to read the volatility aggregator
The big number at the top is the average of every live tracker on the 0–10 scale. As a rough guide: 0–2 is calm, 2–4 is normal, 4–6 is active, 6–8 is high, and 8–10 is storm-level volatility. The single most useful signal is agreement: when several independent trackers spike on the same day, it's strong evidence of a real, broad Google algorithm update. When just one tool moves while the rest stay flat, it's usually that tool's own keyword noise rather than a Google-wide change.

What each tracker measures
| Tracker | What it measures |
|---|---|
| Mozcast | A 'weather temperature' for the SERP — hotter days mean more ranking change across its keyword set. |
| Algoroo | A 'roo' flux score from DEJAN that sums ranking movement across a tracked keyword set. |
| Semrush Sensor | A 0–10 volatility score broken down by category, device, and country. |
| AccuRanker Grump | A 'Grump' rating — the grumpier the tiger, the more volatile the rankings that day. |
| Advanced Web Ranking | A daily fluctuation index built from a large keyword sample. |
| CognitiveSEO Signals | A fluctuation signal that flags days with unusual ranking movement. |
| Zutrix Tension | A 'tension' score with a risk level indicating how turbulent the SERP is. |
Frequently asked questions
What is Google search volatility?
Google search volatility measures how much search engine results pages (SERPs) change from one day to the next. When Google adjusts its ranking systems — through a core update, spam update, or smaller ongoing tweaks — rankings shift, and volatility tracking tools quantify how big that movement is. High volatility usually means a lot of pages are moving up or down in the results.
What is a SERP volatility tracker?
A SERP volatility tracker monitors a fixed set of keywords every day and calculates how much the top results changed compared to the previous day. Each tool — Mozcast, Algoroo, Semrush Sensor, AccuRanker and others — reports the result on its own scale. This aggregator normalizes them all to a single 0–10 scale so you can compare them side by side.
How do I know if there's a Google algorithm update?
The strongest signal is agreement across tools. If several independent volatility trackers spike on the same day, that's strong evidence of a real, broad algorithm update. If only one tool spikes while the others stay flat, it's more likely that tool's own keyword set or measurement noise rather than a Google-wide change.
What does the 0–10 scale mean?
Every tracker uses a different native unit (Mozcast reports a 'temperature' in °F, Algoroo reports a 'roo' value, Semrush uses 0–10, and so on). To compare them fairly, each reading is mapped to a shared 0–10 scale where roughly 0–2 is calm, 2–4 is normal, 4–6 is active, 6–8 is high, and 8–10 is storm-level volatility.
Which volatility tools does this aggregator include?
It pulls live readings from public sources including Mozcast (Moz), Algoroo (DEJAN), Semrush Sensor, AccuRanker Grump, Advanced Web Ranking, CognitiveSEO Signals, and Zutrix Tension, with more sources added over time. Each tracker links back to its original source.
How often is the data updated?
The page re-checks every source about every six hours. Most trackers publish one reading per day, and not all on the same day, so the consensus uses each tracker's most recent reading from the last three days rather than letting one early publisher swing the number.
Is there a Google algorithm update right now?
Check the banner at the top of the tool. It reads Google's own Search Status Dashboard and shows any confirmed ranking update that is still rolling out. The chart also marks every confirmed update in the last 30 days. If the trackers spike and there's no confirmed update, it may be an unannounced change or noise in individual tools.
Is this tool free to use?
Yes. It's completely free, requires no signup, and uses only publicly available volatility data from each tool's own source — no personal data and no paid data redistribution.
What should I do when volatility is high?
When volatility is high, monitor your own rankings and organic traffic closely, avoid making large site changes mid-update, and wait for the update to settle before drawing conclusions. When volatility is low, it's generally a safer window to ship content and technical changes.
