If you’ve noticed seismic shifts in your rankings recently, you’re not alone. Google rolled out its much-anticipated March 2025 Core Update, and it’s already reshaping the search landscape in big ways. But don’t panic—whether you’re a local business in Chelsea or a global e-commerce site, we’re here to break down what’s changed, why it matters, and what steps to take next.
At London SEO Services, we’ve had our ear to the digital ground since the chatter began. Let’s dive into the nitty-gritty of the March 2025 Google Core Update.
A Quick Refresher: What Is a Google Core Update?
In essence, a Google Core Update is a significant tweak to how Google ranks websites. It’s not about penalising your site for one dodgy link or a rogue keyword. Instead, it’s a broader recalibration of what Google believes to be helpful, high-quality, and trustworthy content.
These updates often affect websites across industries. And this March, Google took a big swing at what it calls “scaled content abuse”, low-quality AI-generated content, and websites with poor EEAT (Expertise, Experience, Authoritativeness, Trustworthiness).
March 2025 Core Update: What’s New?
Here’s a quick rundown of what the March 2025 update brought to the table:
1. Crackdown on Low-Value Content
Google is increasingly ruthless with sites pumping out unhelpful, regurgitated, or AI-spun content. It wants people-first content—something we’ve been championing at London SEO Services all along.
2. More Weight on EEAT
Websites that demonstrate clear authorship, genuine experience, and trustworthy sourcing saw improved rankings. Anonymous blogs? Not so lucky.
3. Demotion of Expired Domains and PBN Abuse
Using expired domains to publish thin affiliate content or game link juice? This update is targeting precisely that kind of behaviour.
4. Product Review and Affiliate Page Scrutiny
Sites that rely heavily on review content without true expertise or unique insight took a major hit.
5. Visibility Drops for AI-Overuse
Pages clearly written by unchecked AI tools, without editorial oversight or humanisation, are facing visibility losses. Even helpful content can get hit if it feels robotic.
Who’s Been Affected Most?
Our internal audits and client reports show that the sectors most impacted include:
Affiliate websites reliant on templated reviews
Niche blogs with thin or overly-automated content
Directories without unique value or trust signals
E-commerce platforms lacking detailed, experience-driven product descriptions
On the flip side, local businesses with rich service pages and real-world experience have seen gains—especially those investing in Local SEO strategies.
Google’s Perspective: Why This Update?
According to Google’s March 2025 announcement, the mission remains the same: “to reward original, helpful content that demonstrates real expertise and value to users.” In particular, they noted a desire to reduce low-quality results in SERPs by over 40%.
This update aligns with the wider shift towards Search Generative Experience (SGE), where snippets and overviews in AI-powered search interfaces prioritise clarity, trust, and authority.
What Should You Do If Your Site Was Affected?
1. Audit Your Content
Start by identifying pages that dropped. Use tools like Search Console, Ahrefs or SEMrush. Check whether those pages:
Provide unique value
Show real experience or expertise
Contain fluff, filler, or reworded AI mush
Run a Free Site Audit if you’re unsure—our tools spotlight thin pages, duplicate issues, and quality gaps in seconds.
2. Re-Evaluate Your Author Signals
Add author bios, dates, and sourcing to your blog. Real humans writing content? Say so! Link their credentials to trusted profiles or LinkedIn.
3. Re-optimise with Intent in Mind
Are your pages truly solving the user’s intent? Or are they stuffed with keywords and filler? Think quality over quantity. For tailored optimisation, explore our SEO Services.
4. Diversify Your Content Format
Mix it up—include infographics, original photos, videos, or even customer quotes. Google loves variety and rich media, especially in SGE previews.
5. Focus on Location-Relevant Content
For UK businesses, especially those targeting London, ensure your pages reflect genuine local insight. See our bespoke Local SEO plans for examples.
