Google closed out its December core update yesterday. This morning it started a spam update. The Search Status Dashboard entry reads: “Released the December 2024 spam update, which applies globally and to all languages. The rollout may take up to 1 week to complete.”
For anyone who manages a website, the last six weeks have been crowded. The November core update ran from November 11 to December 5. The December core update began on December 12 and, according to Search Engine Land, finished on December 18, much faster than the two weeks Google had suggested. When people asked why there were two core updates in back-to-back months, Google’s answer was that “we have different core systems we’re always improving.”
Now a spam update, starting the day after.
It would be easy to lump all of this together as “Google volatility.” I think it is more useful to pull the season apart, because it actually contains three different mechanisms, and they mean different things for a company’s presence in search.
Three mechanisms in six weeks
Reassessment. The two core updates are Google re-weighing quality and relevance across the web. A page can lose ground without having done anything wrong, simply because others are judged more useful. Taste, in a sense.
Clarified policy, enforced by people. On November 19, Google updated its site reputation abuse policy. The key sentence is blunt: its review of cases showed that “no amount of first-party involvement alters the fundamental third-party nature of the content.” In other words, licensing deals, white-label arrangements and partial ownership do not make third-party content on a strong domain acceptable if its purpose is to borrow that domain’s ranking signals. Google said violations are handled with manual actions, with notices in Search Console.
Automated spam enforcement. Today’s update improves Google’s systems for detecting practices that break its spam policies. It is not a judgment about relevance. It is closer to enforcement.
The same November post contained a fourth idea that is easy to miss. Google said it also has systems that treat sections of a site that are starkly different from the main site as if they were standalone sites, and that resulting traffic changes are not penalties. So a sub-section can lose visibility simply because it no longer inherits the main site’s reputation.
Why this matters for reputation
Companies often treat certain search surfaces as durable authority: a sponsored “best of” listing on a well-known publisher’s domain, a partner section on a high-ranking site, a page of content placed on a host because the host ranks well. When those pages rank, they can feel like earned reputation.
The policy picture this season says otherwise. If a favorable result depends on borrowing someone else’s ranking signals, it is exposed to policy, not just to Google’s changing taste. Policy enforcement can remove a surface outright, and the timing is not under the company’s control. I made a version of this point in the spring, after Google introduced its site reputation abuse policy; November’s clarification closed the loophole many had been relying on.
The reverse can also be true. Some negative or low-quality pages about a company sit on sites that may be affected by spam enforcement. But it would be a mistake to plan around that. Nobody knows yet what this update will touch, and it will be a week before the rollout is even complete.
What to do this week
Very little, in terms of reaction. Note which of your important results sit on surfaces that rely on borrowed authority, and ask whether you would be comfortable if they disappeared. Then wait for the rollout to finish before drawing conclusions from any movement, and remember that the holiday weeks are a noisy time to read traffic data.
The broader lesson from this run of updates is simple enough. Ranking can be lost to a better page. It can also be lost to a rule. The second kind is much easier to see coming.
