If your rankings or traffic moved in the last day, the December 2024 spam update may be the reason. Google started it on 19 December 2024. It applies to all languages worldwide, and Google says the rollout may take up to a week.
Google has not said which kinds of spam it focuses on this time. So the honest answer to “what does it target?” is: pages that break Google’s spam policies, found by improved automated systems. Below I explain what that means for you, how to tell whether your site was hit, and what I would do over the holidays.
What Google Has Confirmed About the December 2024 Spam Update
Google announced the update on its Search Status Dashboard and on the Search Central social accounts. The announcement was short. Here is everything we know so far.
- Start date: 19 December 2024, at about 9:00 a.m. Pacific time.
- Scope: global, for all languages.
- Rollout time: up to one week. Google will post on the dashboard when it is done.
- Spam types: Google did not name any.
- Size: Google did not say what share of searches is affected.
That is a lot less detail than some past spam updates. In October 2023, for example, Google listed cloaking, hacked, auto-generated and scraped spam. This time it simply released the update and pointed to its spam policies.
The Timing: One Day After a Core Update
Timing matters a lot here. The December 2024 core update started on 12 December and finished on 18 December. The spam update began the very next day.
So many sites have now had two Google changes in about a week. If your traffic dropped, you need to work out which one caused it. I cover how to do that further down.
This is also the third confirmed spam update of 2024. The first came with the March 2024 core update, and the second was the June 2024 spam update. Add the August, November and December core updates, and 2024 has been a busy year for anyone tracking rankings.
What Is a Google Spam Update?
Google runs automated systems all the time to find spam in search results. Every so often it makes a notable improvement to those systems. When that happens, Google calls it a spam update and lists it on the Search Status Dashboard.
Better systems catch sites they missed before. Those pages can then rank much lower or drop out of results completely.
Google’s main tool for this is SpamBrain, its AI-based spam prevention system. Google trains it to spot patterns that spam sites share, including new tricks. A spam update often means SpamBrain or a related system has learned something new.
Spam Update vs Core Update
People mix these up, so here is the simple difference.
| Core Update | Spam Update | |
|---|---|---|
| What it changes | How Google judges overall quality and relevance | How well Google detects pages that break spam policies |
| Who it affects | Almost any site, even ones doing nothing wrong | Mainly sites using spam tactics, or sites with spam on them |
| Typical effect | Gradual gains and losses across many pages | Sharp drops, sometimes pages removed from the index |
| Recovery path | Improve content and overall site quality | Remove the spam and wait for systems to notice |
In my experience, a normal business site that has never bought links, mass-produced pages or been hacked is very unlikely to be hit by a spam update. Core updates are a different story.
What the December 2024 Spam Update Is Likely to Target
Since Google named no focus, the best guide is the list of spam policies for Google web search. Any page breaking one of these can be caught. These are the ones I see cause the most trouble on real sites.
Scaled Content Abuse
This is making lots of pages mainly to rank, with little value for readers. It does not matter how the pages are made: by AI, by templates, by cheap writers, or a mix.
Common examples are thousands of near-identical location pages, or AI articles published in bulk on every keyword in a tool export. Google added this policy in March 2024, and I covered it in my guide to the March 2024 core update and new spam policies.
Expired Domain Abuse
This is buying an old domain that used to have a good reputation, then filling it with low-value content to profit from its past. A domain that once belonged to a charity, now full of casino reviews, is the classic pattern.
Site Reputation Abuse
This is third-party content placed on a trusted site mainly to borrow that site’s ranking strength. Think coupon sections or payday loan reviews on a news site, run by an outside company.
Google has mostly enforced this with manual actions so far. In November 2024 it also made clear that first-party oversight does not make such content acceptable. Google has not said whether this spam update deals with it, so I would not assume either way.
Link Spam
Buying or selling links that pass ranking credit, large link exchanges, and automated link building all count. If your rankings depend on links like these, any improvement to Google’s link detection can hurt.
Google’s spam updates page has one warning worth knowing. When an update removes the benefit of spammy links, that ranking boost is gone for good. Cleaning up later does not bring it back.
Hacked Content, Cloaking and Sneaky Redirects
These are older problems, but they still catch site owners out. Hackers can add pages, links or redirects to your site without you noticing.
- Hacked content: pages or code someone added through a security hole.
- Cloaking: showing Google one thing and visitors another.
- Sneaky redirects: sending visitors somewhere different from what Google saw.
I usually see hacks on WordPress sites running old plugins. The owner often has no idea until traffic falls.
Other Common Policy Breaks
- Thin affiliate pages: product pages copied from the merchant with nothing added.
- Doorway pages: many similar pages that all funnel visitors to one place.
- Scraped content: copying other sites’ content without adding value.
- User-generated spam: spam posted in your comments, forums or profiles.
- Keyword stuffing and hidden text: old tricks that still trigger spam systems.
How to Tell If the Spam Update Affected Your Site
Spam updates are automatic. Google does not send a Search Console message when one affects you. You have to read the signs in your own data.
Here is the order I check things in.
- Check Manual actions and Security issues first. Open both reports in Search Console. A manual action is a separate penalty from a human reviewer, and a security issue points to a hack. Either one changes what you need to do.
- Find the exact start of the drop. In the Performance report, compare clicks and impressions day by day. Search Console now has a 24-hour view, which helps you see changes by the hour around 19 December.
- Match the drop to the right update. A decline that began between 12 and 18 December points to the core update. A sudden fall on or after 19 December points more to the spam update.
- Look at which pages lost traffic. In the Pages tab, sort by the change in clicks. A spam hit often affects one section, one page type, or the whole site at once.
- Check whether pages left the index. Search for a few of your key URLs. Use URL Inspection on pages that have vanished. Pages that drop out completely are a strong spam signal.
- Rule out your own changes. Site migrations, robots.txt edits, broken redirects and tracking problems can all look like an update hit.
I always rule out technical problems before blaming Google. It saves a lot of wasted effort.
Signs That Point to a Spam Hit
- A sharp drop over one or two days, not a slow slide.
- Pages that no longer rank even for their own brand or exact title.
- Large-scale pages, bought links or guest content on your site.
- Unknown pages showing in a
site:yourdomain.comsearch.
Signs That Point Elsewhere
- Small ups and downs across many pages. That is more typical of a core update.
- Seasonal drops. Late December is quiet for many B2B sites, so compare with the same days last year.
- Competitors gaining because they improved, not because you lost trust.
What to Do This Week
The rollout is still running, so rankings may keep moving for several days. Do not make big changes based on one bad day.
If You Were Not Hit
Good. Still, use the quiet holiday weeks for a short check. Look for hacked pages, old bulk content, and any link deals that you or a past agency set up. Fixing these now protects you from the next update.
If You Think You Were Hit
- Wait for the rollout to finish. Give it the full week and a few days after. Early numbers often swing.
- Read the spam policies line by line. Be honest about which ones your site may break. This step is uncomfortable, but it is the one that matters.
- Remove or fix the problem. Delete or improve thin bulk pages. Clean up hacked content and patch the security hole. Stop paid link deals and, where you can, have those links removed or marked
rel="sponsored". - Deal with third-party content. If outside partners publish on your domain mainly for search traffic, move it, noindex it, or remove it.
- Keep a change log. Note what you fixed and when. It helps you connect later recovery to your actions.
- Be patient. Google says sites that fix spam issues may see improvement over several months, as its systems learn the site now follows the rules.
Only file a reconsideration request if you have a manual action. For an automatic spam update, there is nothing to submit. You fix the site and wait.
What I Would Not Do
- Do not disavow every link in a panic. I only use the disavow tool when I know of bought or manipulative links, or have a manual action for them.
- Do not delete good content. Remove what breaks the rules, not pages that simply lost rank to a competitor.
- Do not move to a new domain to escape. It does not fix the cause, and the same problems usually follow you.
- Do not trust quick-fix offers. Nobody can guarantee recovery from a spam update in days.
Practical Examples
Here are a few common site types and how I would think about each.
A Local Service Business
Say a plumber has one page per nearby town, each with the same text and only the town name swapped. That pattern can look like doorway pages or scaled content. I would merge them into fewer, genuinely useful area pages with real details about the service in each place.
An Affiliate Review Site
If product pages repeat the merchant’s description with a buy button, they risk the thin affiliate label. I would add real testing notes, comparisons and clear opinions, or cut the weakest pages.
A Publisher With Partner Content
Sponsored sections run by outside companies, aimed at search traffic, are a site reputation risk. Even if no manual action has arrived, I would review who controls that content and why it exists.
A Blog Built With AI Tools
Using AI is not spam on its own. Publishing hundreds of unedited AI articles to catch keywords is. My rule of thumb is simple: if a page would not be worth publishing without search traffic, it is a risk.
How the December 2024 Spam Update Fits Into 2024
Looking back at the year, the direction is clear. Google added new spam policies in March, started site reputation abuse enforcement in May, ran a spam update in June, and clarified the site reputation policy in November. Now it ends the year with another spam update.
The message I take from this is that Google wants to cut low-value pages made mainly for search. The tactics change, but the target stays the same. Sites built for real readers rarely need to worry about spam updates.
Final Thoughts on the December 2024 Spam Update
The December 2024 spam update started on 19 December, applies to all languages, and should take up to a week to roll out. Google did not name specific spam types, so judge your site against the full spam policies rather than guessing.
If you saw a drop, first separate it from the core update that ended on 18 December. Then check for manual actions, hacked pages, bulk content and bought links, and fix what you find. My next step for most readers is simple: wait for Google’s completion notice on the dashboard, then compare a full week of data before and after.
