In March 2025, Google rolled out its first core update of the year, which completed on March 27th after a two-week rollout that began on March 13th. As with all broad core updates, this one brought significant shifts in search engine results pages (SERPs), with some sites seeing dramatic losses while others benefited from increased visibility. The SEO community had anticipated this update following months of volatility and subtle ranking changes that hinted at a more significant algorithmic adjustment.

This article breaks down the major outcomes of the update, highlights the types of sites and content affected, and offers actionable advice for webmasters, marketers, and content creators moving forward.

 

What are Google Core Updates?

Google’s core updates are broad changes to its search algorithms and systems. These updates are not targeted at specific sites or industries but rather are designed to improve Google’s overall ability to assess content quality and relevance and better match users with the most helpful search results.

The effects of core updates can be far-reaching. Sites that were previously ranking well may suddenly see a drop, and vice versa. These fluctuations are a natural byproduct of Google re-evaluating content using improved or updated criteria.

 

Key impacts of the March 2025 Core Update

1. Forum content faces new scrutiny

One of this update’s most immediately noticeable impacts was a recalibration of how forum and user-generated content is ranked. In the months leading up to this update, platforms like Reddit, Quora, and niche forums had seen a substantial boost in visibility following Google’s emphasis on first-hand experience and unique perspectives, especially as part of its ‘Hidden Gems’ initiative, which launched in 2023.

However, with the March 2025 update, some of that visibility has been dialled back. While Reddit performed well overall, many smaller forums and UGC platforms experienced noticeable declines. This suggests that Google is refining how it evaluates these sources, emphasising authority, coherence, and the moderation quality of discussions.

2. Cross-industry volatility

Unlike some previous updates that had a more concentrated impact (like the 2022 Product Reviews updates), the March 2025 update was truly broad in its reach. Websites in sectors like retail, healthcare, government, education, entertainment, and publishing all reported fluctuations.

This widespread movement is typical of broad core updates and reflects Google’s attempt to apply updated ranking criteria across all industries and content types.

3. Programmatic SEO takes a hit

Another major target of the update seems to be low-value, programmatically generated content. Over the last year, the rise of AI tools and automated content platforms has led to a surge in sites publishing thousands of SEO-focused pages with little original insight or user value.

Many of these sites were heavily impacted, especially in local SEO (e.g., ‘Best plumbers in [City]’ pages), affiliate marketing, and product comparisons. While Google has not outright penalised automation, it clearly reinforced the importance of human oversight, editorial quality, and user-first content creation.

If your site publishes templated or semi-automated content at scale, this is a good time to review whether that content genuinely serves a purpose for the user.

 

How the SEO community is reacting

Reactions to the update have been mixed. Some SEOs welcomed the update, especially those who had spent the last year focusing on improving content depth, user experience, and E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness). Others struggled to maintain rankings, particularly those reliant on mass content production or thin affiliate pages.

Reports from SEO monitoring tools like Semrush and Sistrix noted heightened volatility throughout the rollout period, with visibility scores shifting dramatically even for long-established domains. However, unlike the chaos of past updates, there was a general sense that this update rewarded high-quality, original, helpful content, just as Google has long said it aims to do.

 

Google’s purpose for the update

As usual, Google’s commentary was somewhat limited, but the company reiterated that core updates are about improving how its systems assess content overall.

They emphasised again that there’s ‘nothing wrong’ with pages that lose rankings after an update. Rather, it might be that other content is simply being recognised as more relevant or helpful based on newly refined algorithms.

Their advice remained consistent: focus on content quality, user intent, and holistic site trustworthiness.

 

Strategic takeaways SEOs and website owners

So, what should you do if this update impacted your site? Here are our top strategies moving forward:

1. Audit your content thoroughly

Now’s the time to evaluate which pages lost traffic and why. Look for patterns in terms of content quality, thinness, outdated information, or poor structure. Updating and improving these pages can help in future updates.

2. Focus on E-E-A-T

Ensure your content clearly communicates who wrote it, why they’re qualified, and that it has been fact-checked or updated where necessary. Add bios, citations, references, and transparency features like contact info and editorial guidelines.

3. Refine or remove low-value programmatic pages

If you have pages generated en masse with templates or AI and have minimal differentiation or value, consider consolidating, improving, or removing them. Even if the content is technically ‘unique’, Google is clearly prioritising depth and usefulness over volume.

4. Improve internal linking and site UX

A well-structured site with strong internal linking and good navigation helps Google and users. Reduce bounce rates by making your pages more engaging and easier to explore.

5. Diversify traffic 

No matter how optimised your SEO is, relying solely on Google traffic can be risky. Consider building email lists, social media channels, and direct traffic sources to reduce vulnerability to future updates.

 

What’s next for Google Search in 2025?

While this update focused heavily on quality and scale, the SEO landscape continues to evolve rapidly, especially with the rise of AI, voice search, and AI-powered search experiences like Google’s Search Generative Experience (SGE), currently only available in the US, which will likely roll out more widely later in the year.

This means that content strategies must go beyond traditional SEO tactics. They must consider how content appears in rich results, how it’s cited in AI-generated summaries, and how it meets real user needs across various touchpoints.

 

Final thoughts

The March 2025 Google Core Update reaffirmed Google’s commitment to delivering high-quality, relevant content to users. While some site owners experienced losses, others gained by investing in strong content strategies focused on real user value.

Whether you were impacted or not, the best path forward remains the same: produce authentic, helpful, well-structured content that users (and search engines) can trust.

Last week, myself and Lisa, one of our Content Executives, took a jump without a parachute into the whirlwind that is BrightonSEO. And oh boy, was it an experience. Get ready for a peek into the talks, both good and bad, and maybe even a few unexpected takeaways from the UK’s biggest search marketing conference.

The key takeaways

1. AI is certainly making its mark on the industry, and some are using it more responsibly than others…
2. Traffic is down across the board, and a lot of that may be due to AI Overviews and GA4’s unruliness.
3. Despite much shoulder shrugging and attempts to wrangle LLM and AI Overview data, the future of SEO is still unknown. The people whose talks were most effective weren’t trying to guess what Google could want—they were making their foundations as solid as possible to weather whatever storm comes our way.
   
   

Session highlights – a deeper dive

BrightonSEO has long been hailed as THE digital marketing conference to attend if you want to learn new tricks, get in-depth data insights, and get a glimpse into the future of SEO. While there were nearly a hundred talks to attend this year, there were undoubtedly some highlights:

Emily Barrington – Leveraging competitor research to accelerate success

Emily, owner of her own agency, Barrington SEO, had the number one talk of BrightonSEO (in my humble opinion). I have three pages of scrawled notes as I tried to keep up with the insane amount of advice and tactics she shared on conducting competitor analysis. From how to reverse engineer a competitor’s SEO tactics (hint: it’s not just keyword analysis!) to capitalising on gaps in their strategy, this talk was outstanding for its efficiency, abundance of practical advice, and genuine knowledge of the industry. 

Colette Masso Del Llano – Is AI having a negative effect on your customer trust?

This main stage talk was really enlightening as a Content Manager and strategist for Fusion. How we use AI is changing so much, and how we, as an external agency, can build trust with our clients is paramount to maintaining our strong relationships. One of Collette’s most shocking (but affirming) stats in her talk was that 72% of people said they would have a negative view of a brand if they thought they had used AI to write their content. Here at Fusion, all of our content is human-written and human-proofed. While the multitude of talks on how to scale content using AI concerned me, this talk helped me remember that just because the crowd are going one way doesn’t mean that they should. 

Marco Giordano – How to do content auditing with SEO/web data for small & big websites

We have a real mix of clients here at Fusion, from local brands with only a handful of main landing pages to industry-leading giants with thousands of pages on site. This talk was extremely helpful in identifying how you should differ your tactics for auditing between big and small businesses, from internal linking structures to the seasonality of content. Marco also had an exceptional number of handy graphs and charts, which you can find in his BrightonSEO slides. 

Rana Abu Quba Chamsi – Mastering cross-platform content strategy

Even before the full schedule for BrightonSEO 2025 was announced, I had seen Rana’s talk title and was instantly intrigued. Cross and multi-channel strategies are crucial to the growth of a client, and so I was pretty excited to see how Rana was going to bring together onsite content and organic social media to create some magic. She didn’t disappoint! 

I was particularly intrigued by her advice to repurpose your workflow, something that we have tried with different clients who manage multiple agencies and found tricky in the past. By starting with onsite content at the core of things (e.g. videos, blog posts, podcasts) and using these as jumping off points for different social formats, you can completely change the way you work, and bring in so much more efficiency when it comes to reporting and analsying too. 

Navigating misguided AI and SEO practices

However, not everything was as excellent as these highlighted talks – the elephant that seemed to be squeezed into every room in Brighton was the misuse of AI, and the promotion of some bad SEO habits that I never would have expected. 

Faking E-E-A-T

One presentation, in particular, suggested a “fake it ’til you make it” approach to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). While I understand the idea of strategically highlighting your strengths, the concept of faking trust just doesn’t sit right with me.

E-E-A-T is a framework that Google introduced back in 2014 (this is when the emphasis on E-A-T became more prominent in their Search Quality Rater Guidelines, with the ‘Experience’ element being added later) to encourage website owners to create content for their sites that genuinely improves the trustworthiness of their brand. If Google could identify that you were genuine, with real experts in the field, a solid knowledge base, and lots of experience working within an industry or with a type of product, then they were more likely to prioritise your content in SERPs. 

For me, genuine trust isn’t something you can manufacture with quick fixes. Think of it this way: you can’t suddenly claim to be a medical expert by just throwing around jargon or citing a few studies. Real expertise comes from years of study, practical experience, and ideally, recognised credentials. It’s the difference between a blog post mentioning a health condition and one written by a practising doctor sharing insights from their clinical work.

This isn’t about being the loudest or most boastful – it’s about consistently providing well-researched, accurate, and insightful information. It’s about demonstrating a deep understanding of a topic through the quality of your content and your engagement with your audience. 

Ultimately, both your audience and search engines are becoming increasingly sophisticated at recognising the difference between genuine authority and superficial claims (another great BrightonSEO talk by Giulia Panozzo if you’re interested). Building that real expertise, sharing those authentic experiences, and letting those knowledgeable voices lead your content is the best long-term strategy for building lasting trust and achieving sustainable success.

Using AI for everything (and neglecting your proofing)

I was also quite disappointed to hear so many talks advocating for AI-written content, especially AI content written at scale. One BrightonSEO speaker boasted about having already written 250,000 landing pages this year, with his agency set to have written 1 million by the end of 2025. Another, quite senior, member of another agency advocated using AI to produce content at scale without even taking the time to have a human proof it, because their interpretation of Google’s guidelines on AI content is that as long as it’s helpful, it doesn’t need to be well-written. 

I was honestly shocked at the admissions coming from senior digital marketers on one of the biggest platforms that can be provided in our industry. While AI can be a real time saver for some of the more mundane internal tasks that none of us like to do – summarising a very long client email, or picking out the main actions from a recorded meeting – using AI to write content en masse is only going to contribute to the insane volume of AI slop out there online. Gartner predicts that by 2030, 90% of all online content could be AI-generated.

Proofing might be one of the most tedious jobs out there for writers and strategists alike, but there isn’t a single AI tool out there that will be able to interpret the nuance of human communication like a person can. Sure, it can tell you if you spelt onomatopoeia wrong, or if you’ve written something with a low Flesch reading score, but can AI really create the kind of content that builds a connection with other people?

Why does all of this matter for you?

Whether you’re an in-house marketer, working in an agency or purely client-side, it’s essential to know what’s happening in the search landscape and how digital marketers are changing their tactics to keep up. 

While I didn’t agree with some of the tactics and approaches being promoted at BrightonSEO this year, it’s still really important to be aware of their popularity and how other marketers are planning on tackling different issues. Problems such as low traffic, the problematic introduction of ‘GEO’ (Generative Engine Optimisation – essentially how you optimise your content to appear in AI Overviews on Google) and decreased clicks were all addressed in a variety of ways. I’d highly advise getting access to the recorded talks so you can watch through and find the advice that works for you. 

Not only should you be paying attention to what the industry is doing so you can find ways to implement their helpful tips, but also analyse their advice with critical thinking to make sure that their approaches align not only with your marketing goals and ambitions, but with your moral compass too. Not every approach is going to be 100% ethical (or even lawful, as we saw), so make sure you take every talk’s advice with a pinch of salt – your SEO strategy should be tailored to you and your brand, something that Fusion excels at.

We never take a blanket approach to content strategy, SEO strategy, or any creative work. We strive to ensure that every client’s needs and goals are met through our combined research and technical skills, our experience with a huge variety of industries, and most importantly, our genuine care for our clients.
