December 2025 Google Core Update: What eCom Marketing Teams Need to Know

The Update

Last week, Google quietly rolled out its December 2025 Core Update. Dropping a core update right in the middle of the December crunch is certainly one way to keep the industry awake.

Announced on December 11 via Google’s Search Status Dashboard, this marks the third major core update of 2025 and follows the March and June core releases earlier in the year. 

What’s Happening?

Google has begun rolling out its December 2025 Core Update. As publicly stated on LinkedIn and other social media platforms, the update is “designed to better surface relevant, satisfying content for searchers from all styles of sites” – Google Search Central, 2025.

The rollout may take up to three weeks to complete and is expected to influence rankings globally for brands in many industries, and we predict some changes heading for eCommerce stores.

Google Confirms Rollout of Smaller Core Updates

Google’s Search documentation now explicitly states that the company conducts smaller, unannounced core updates throughout the year. While not significant enough for formal public announcements, these quieter updates can still affect a website’s search rankings, either positively or negatively. The impact depends on various factors, including how well the site’s content aligns with Google’s quality expectations.

The latest Core Update is live, and while the SEO landscape is constantly shifting, here are five things we’re advising our clients and other eCommerce brands to focus on right now.

What you can do:

1. Focus on people-first content: Google continues to reward content that is genuinely helpful, trustworthy and meets user intent. This is a good starting point for site owners; consider how you can improve your content in meaningful ways. For example, it could be that rewriting or restructuring your content makes it easier for your audience to read and navigate the page.
2. Analyse performance with context before reacting: This update landed during a highly seasonal period, so don’t panic over short-term volatility. Use Search Console and GA4 together to separate normal seasonal fluctuations (especially this time of year) from algorithmic impacts and analyse with context before you make any rash decisions.
3. Showcase expertise (E-A-T-T) feature expert-written content: Provide in-depth product insights and build trust through authoritative sources. Google has increased scrutiny on eCommerce category pages; having thin, duplicate, or AI-generated content is now more likely to be penalised, while well-structured, informative, and user-focused pages can win you more search traffic. Therefore, your goal should be to create well-structured, informative, and user-focused category pages.
4. Pay attention to the small movements, not just the big updates: Google has been clear that it now rolls out smaller, unannounced core updates all the time. This means improvements you make today don’t need to wait for the next “big” update to show results. Focus on tracking incremental changes to rankings and impressions at the URL level. Our observations show that SEO improvements are increasingly cumulative. For guidance on how long this process takes, refer to the Google documentation on Core Updates.
5. Avoid doing “quick fix” changes: Resist the urge to remove sections, strip content, or make sweeping changes based on hearsay. If a change doesn’t improve the user experience, it’s unlikely to help SEO in the long run. Instead, focus on making changes that make sense for your users, and as we guide all our clients, sustainable improvements beat quick fixes every time.

Core updates often bring short-term ranking volatility. If you’ve noticed meaningful changes since December 11, there’s a strong chance they’re linked to Google’s latest core update or the smaller, ongoing adjustments happening behind the scenes. Our team is well-placed to help you navigate this update and stay ahead of the next one. If you have questions about what this means for your business, your organic performance, or how to get ahead with AI-driven SEO, feel free to reach out to our friendly team.
