Daily tracking across 10,000 keywords in 20 niches · Google Search, Desktop, United States
SERP volatility is how much Google's rankings reshuffle from one day to the next — the more results reshuffle, the more likely it's an algorithm update rather than normal noise.
Our tracker measures that daily reshuffling across 10,000 keywords in 20 niches (US, desktop), and breaks it down by niche, search intent, AI Overview presence, and ranking depth — top 3 through top 50 — instead of collapsing it into one number. For your own rankings, that's what SE Ranking's Rank Tracker is for.
Each day, we compare every keyword's top results to the day before. Every position swap adds to that keyword's delta — a result that falls out of the zone counts as the maximum possible move for that slot. We scale the total to a 0–100 score per keyword, then average across every keyword with a result in that zone that day:
It's a position-delta approach, not a click-weighted one — a move from #2 to #7 counts the same as #92 to #97 within a zone. Narrow to Top 3 when only the highest-value positions matter to you.
Next time your rankings move, check here first. If the market's spiking too, you're probably looking at an algorithm update, not a site problem.
Since September 2026, Google has sometimes returned unrelated results to automated checks, and rank trackers across the industry have had to deal with it. Our team monitors this continuously and filters out unreliable results pages before they reach our reports. No tracker can promise Google won't change something tomorrow, so treat a sudden spike as a signal to verify, not a verdict. In our study of 10,000 keywords, unrelated results never appeared in the top 5. Of the pages affected, 96.5% showed them from position 9 down, and 3.5% from positions 6-8. For the cleanest read, switch the Impact Zone to Top 3 or Top 10. You can follow the latest updates on our status page.
Each day, we compare every keyword's top results to the day before within your selected Impact Zone. Every position swap adds to that keyword's delta, which we scale to a 0–100 score and average across every keyword with a result in that zone — a position-delta approach, not a click-weighted one.
Most volatility trackers report a single blended score for the whole market. Ours adds two cuts that others don't expose: an Impact Zone, so you can isolate volatility in just the top 3 or top 10 instead of reading one blended number, and an AI Overview filter, so you can see whether volatility looks different for queries where Google is currently showing an AI Overview. We also overlay confirmed Google update windows directly on the trend line, sourced from Google's own status feed.
They're score bands on the same 0–100 scale: 0–39 is Regular (typical day-to-day movement), 40–69 is Elevated (more churn than usual), and 70–100 is Severe (movement consistent with an active algorithm update). They're a reading aid for the gauge, not a separate calculation.
Niche (one of 20 tracked categories, or all at once to compare which are moving most), search intent (informational, commercial, transactional, navigational, or local), and AI Overviews — view all keywords, only those currently showing an AI Overview, or only those that aren't. The AI Overview cut is evaluated per day, so a keyword moves in and out of it as Google shows or hides the Overview.
Alongside the score, four cards show concrete movement counts and percentages: how many search results dropped from Top 10 to below Top 50, jumped from below Top 20 into the Top 3, and the two reverse moves. They appear on the Top 50 zone only, because they count results crossing that outer boundary, which a narrower zone cannot see. You can also toggle a Google algorithm update overlay on the trend line, sourced from Google's own Search Status feed, to see whether a spike in the score lines up with a confirmed rollout window.
It scopes the calculation to a specific ranking depth — top 3, top 10, top 20, or top 50 — so the score reflects only the movement inside that depth. Every keyword left by the other filters still counts. Use a tighter zone (top 3 or top 10) when you care about the positions that actually drive clicks; use top 50 for the broadest read on market-wide churn.
Daily. You can view a rolling 30- or 90-day trend, or pick two specific dates — even weeks apart — to diff directly against each other, which is useful for comparing before and after a confirmed Google update.
A fixed set of 10,000 US-English keywords, spread across 20 niches, tracked daily on Google desktop. It's a research panel curated by our SEO team to represent a broad cross-section of search behavior — not a live index of every keyword, and not tied to any individual site's rankings.
Use our free Google Location Changer to see live Google results for any location. Pick a country, city and language, and compare how the SERP looks on desktop, tablet and mobile. It's a quick way to check whether a spike or drop you see here shows up in real results, in the US or anywhere else. For ongoing monitoring of your own rankings across locations and devices, use Rank Tracker.
Not on this dashboard — it reports on aggregate market movement only. For your own keyword positions, use SE Ranking's Rank Tracker; you can then compare timing against a spike here.
