Google’s March 2025 Core Update has stirred discussion across SEO communities not just because of its broad impact on rankings, but also due to the uncertainty around what exactly changed. As always, Google didn’t publish a specific list of ranking factors, which has led some SEOs and Redditors to speculate about hidden motives or secret algorithm tweaks.
In reality, Google’s silence isn’t new. The company rarely discloses specifics during core updates, and for good reason. Its ranking system is built on highly complex, ever-evolving algorithms. Listing exact criteria would not only oversimplify things, but also open the door to manipulation by those trying to game the system.
That said, Google has consistently emphasized one thing: focus on creating high-quality, helpful, user-first content. With E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) still a core quality signal, the March 2025 update strengthens Google’s commitment to rewarding content that truly serves users. This recalibration also affects link-building strategies especially guest posting, which is often misused as a shortcut for backlinks instead of delivering value.
So, while guest posting wasn’t officially called out in this update, the underlying signals suggest a strong shift: low-effort, SEO-driven guest posts are losing ground, while insightful, relevant, experience-backed contributions still hold value.
But there’s more to it.
We’re now seeing how Google’s AI Overview pulls together real-time answers from various blogs and websites to satisfy search queries. That means blogging is not dead — not even close. In fact, even AI systems like Google’s need human-written, original content as their foundation. AI-generated answers rely heavily on user-created material, which means there’s still a clear path for your content to reach readers.
If your blog or guest post provides real value, and is published on a high-authority website, it can not only rank in traditional search but may also be featured in AI Overviews — increasing visibility and trust in an entirely new way.In short: blogging and guest posting are evolving, not fading. And if done right, they remain a game-changing strategy in your content marketing arsenal.
