On November 11, 2024 Google announced it was rolling retired pinch nan November 2024 Core Update.
Unlike nan erstwhile update (the August 2024 Core Update), nan November update took longer to complete than Google initially estimated. While Google stated that nan update would return 2 weeks, it officially marked nan November rollout arsenic completed connected December 5th—over 3 weeks aft its first launch.
This was a analyzable update to analyze, truthful let’s dive into it.
Analyzing nan Impact and Trends of nan November 2024 Core Update
Like nan August 2024 Core Update, location was a important magnitude of rank volatility starring up to nan November 2024 Core Update.
In an almost ironic twist, nan trends earlier nan update were shown to beryllium overmuch volatile than during nan update, according to nan Semrush Sensor:

Comparatively, during nan August 2024 Core Update, rank volatility remained consistently precocious passim nan update, contempt nan pre-update volatility.

The Semrush Sensor showing spikes of very precocious rank volatility starring into nan August 2024 Core Update
For nan record, and to beryllium very clear, nan accusation supra (and what follows) does not connote that sites impacted by nan November 2024 Core Update knowledgeable small ranking nonaccomplishment than those affected by nan pre-update volatility. The accusation presented is aggregate, intended arsenic a wide believe of nan web. It does not bespeak really individual sites were impacted by nan update.
With that clarified, let’s proceed comparing nan November 2024 Core Update to nan August 2024 Core Update.
I want to statesman pinch nan 60-day rank volatility trends, arsenic they point nan challenges of analyzing nan November 2024 Core Update done aggregate data.
Below, you tin spot that nan inclination instantly starring up to nan August 2024 Core Update showed an summation successful rank volatility:

While nan rank book during nan August 2024 Core Update was analyzable (as discussed successful my study of that update), it pales successful comparison to nan trends observed (in yellow) pinch nan November 2024 Core Update. As noted earlier, nan volatility starring into nan November update was really higher!
This makes it challenging to recovered a baseline play of "relative rank stability" for analyzing nan increases successful rank volatility during nan update, for evident reasons.
To accurately measurement nan effect of nan rollout connected rank volatility, we’ll petition to look further backmost successful time. As a rule, erstwhile pulling this data, we intent to usage accusation points arsenic adjacent arsenic imaginable to nan update.
This enables america to facet successful nan volatility book astir nan update and to spot really impactful nan preamble of nan halfway update to that book was.
Again, we can’t do that here.
Instead, we went backmost to a play of “relative rank stability” seen successful July 2024.
One of nan reasons we went backmost to this play is that it was a akin timeframe to nan baseline accusation we utilized to analyse nan August 2024 Core Update.
This onslaught puts america successful a amended position to comparison nan 2 updates, arsenic we’re now moving pinch a akin baseline that allows america to observe nan volatility effect overmuch effectively. However, location are immoderate limitations, arsenic nan November 2024 Core Update apt occurred incorrect a different "ranking environment" compared to nan August update.
With that successful mind, let’s analyse nan summation successful rank volatility comparative to nan August 2024 Core Update by simply looking astatine nan contiguous play of rank volatility anterior to nan update, without adjusting nan data:

Across nan board, we spot that nan November 2024 Core Update saw small volatility alteration erstwhile compared to nan August 2024 Core Update comparative to nan baseline period.
Notably, a less verticals were small volatile than nan contiguous baseline during nan August 2024 Core Update (see nan Games and Health verticals, for example). However, during nan November 2024 Core Update, this was existent for each verticals.
If we group nan baseline to activity pinch a play of comparative stableness we get a spot of a different accusation scenario.
Here’s nan alteration successful volatility erstwhile we recalculated November’s accusation utilizing a unchangeable play during July 2024:

Overall, nan November 2024 Core Update was small impactful than nan August 2024 Core Update pinch moreover this modified accusation propulsion (again going backmost to a play of volatility “calm” successful July 2024).
While verticals for illustration Sports and Law & Government saw noticeable increases successful volatility successful November comparative to nan August 2024 Core Update others, specified arsenic Internet & Telecom and Business & Industrial, saw small volatility.
Of course, there’s overmuch to it and a overmuch layered onslaught is needed. To that, nan axenic level of conscionable highest volatility seen during nan November 2024 Core Update were too small compared to August:

Here too, nan numbers were accordant crossed each verticals. Setting reside nan News vertical (which is ever highly volatile), not a azygous vertical showed a highest greater than 8 connected nan modular during nan November 2024 Core Update. By comparison, 13 verticals (excluding News) had highest volatility levels of 8 aliases higher during nan August 2024 Core Update.
Moving beyond levels of volatility per se and into really utmost nan rank activity during nan November 2024 Core Update was nan mean position gained/lost stood astir 2.4 positions:

That’s somewhat small than August 2024 Core Update wherever nan mean positions gained/lost stood astatine astir 2.6 positions.
This is simply a style that continues crossed nan board.
When we commencement looking deeper into nan severity of nan ranking activity nan August 2024 Core Update seems to personification been somewhat overmuch drastic.
Back successful August, 9.5% of nan apical 10 URLs position update classed beyond position 20 anterior to its roll-out. That number fell marginally to 9% during nan November 2024 Core Update.

This style only continues erstwhile moving to nan apical results connected nan SERP. Back successful August, 3.3% of nan apical 5 ranking URLs did not moreover ace nan apical 20 owed to nan update. This number falls again during nan November 2024 Core Update to 2.8%:

It seems, then, that nan August 2024 Core Update delivered a somewhat larger effect wide compared to nan November update. However, this does not mean that individual sites couldn’t personification knowledgeable overmuch activity successful November than successful August—this is aggregate data, reflecting simulated rank activity crossed nan web.
This is an absorbing development. In my acquisition analyzing updates complete nan years, it’s comparatively uncommon for an update to look less, alternatively than more, potent than its predecessor.
The Complexity of November 2024 Core Update
Being tin to decipher nan wide effect of nan November 2024 Core Update is 1 thing. Being tin to abstracted retired nan pre-update volatility is different constituent entirely. That overlap tin make analyzing a site's rank capacity a spot tricky.
But hide that! All but a week aft finalizing nan November 2024 Core Update, Google released nan December 2024 Core Update!
It’s an unthinkable barrage of volatility. In a measurement it’s each unprecedented. This is peculiarly existent arsenic Google’s Danny Sullivan said to expect overmuch updates arsenic nan institution nary longer sees them arsenic “major events” but arsenic “routine and continuous."
We are almost surely entering a caller era of volatility and Google updates.
We unrecorded successful absorbing “SEO” times.
