E998: Google's March 2026 Core Update is rolling out, and early data shows significant volatility across search results. I break down what's happening, what people in the SEO community are reporting, and what you should actually do if you want to avoid losing traffic.

We're still in the early phase of the rollout, which means most of what you're seeing right now is speculation mixed with early signals. That said, there are already clear patterns worth paying attention to.

In this episode, I cover: - What Google officially said about the March 2026 Core Update - How this update connects to the March Spam Update and recent Google Discover changes - Volatility data from tools like Semrush, Mozcast, and Advanced Web Rankings - Reactions from the SEO community, including common complaints and concerns - Early examples of sites gaining and losing traffic - Why strong "entity definition" across your site is becoming more important - The risks of topical sprawl and trying to cover too many unrelated topics - How internal linking and contextual relevance play a role in rankings - Observations from competitive niches like iGaming - Why many sites still struggle to understand core updates until weeks later

I also share practical takeaways you can apply right now: - Build content and links at the same time instead of treating them separately - Focus on acquiring backlinks that bring real traffic, not just superficial authority signals - Avoid publishing clusters of near-identical pages targeting slight keyword variations - Create varied content within your niche to reduce obvious SEO patterns - Start narrow, build authority, and only expand once you've established topical depth

If you've been impacted by this update, or you're trying to stay ahead of future ones, this episode will give you a clear way to think about what's changing and how to respond.
