What is the Google Core update?
Google’s March 2026 core update finished rolling out on 8th April, after 12 days. This is the first broad core update of the year, and it has already caused significant ranking movement across the board. Here’s what we know so far – and what it means for your website.
What’s changed?
Google called the March 2026 core update “a regular update designed to better surface relevant, satisfying content for searchers from all types of sites.” The company didn’t share any specific goals for this update or any new guidance.
Like all core updates, it introduces broad changes to Google’s ranking systems, which typically leads to noticeable volatility across search results. Pages may move up or down as Google reassesses content quality across the web, not because of penalties, but because of shifting priorities.
While Google hasn’t changed its official advice, the fundamentals still apply:
• Ranking drops don’t necessarily mean something is wrong
• Recovery often comes with future updates, not immediate fixes
• The focus remains on helpful, reliable, people-first content
Now the rollout is complete, we’re starting to get a clearer picture of what’s actually changed. Early signs suggest a few key shifts:
→ More emphasis on original insight (Information Gain)
Google appears to be rewarding content that adds something new, not just reworking what already ranks. Sites with original data and unique perspectives have seen noticeable visibility gains (some reports suggest increases of around 20%+).
→ Stronger E-E-A-T signals across all content
Experience, expertise and credibility aren’t just for YMYL topics anymore. Signals like detailed author bios, credentials and real-world experience are becoming more important across the board, with a growing number of top-ranking pages including this information.
→ Site-wide performance matters more
Core Web Vitals look to be assessed more holistically, rather than page-by-page. Slower sites, particularly those with poor load times (e.g. LCP above 3 seconds), are seeing more negative impact.
What should businesses and marketers do next?
The complete rollout means you can compare pre-update and post-update performance in Search Console across a full window. Google recommends waiting at least one full week after completion before drawing conclusions from the data. Your baseline period should be the weeks before the 27th March, compared against performance after 8th April.
A drop in rankings after a core update doesn’t necessarily mean that anything is wrong. Core updates reassess content quality across the web, and some pages move up while others move down. The best thing to remember is recovery often comes with future updates, not immediate fixes.
What to action now:
• Analyse any ranking and traffic changes to your web pages
• Identify the winners and losers – which content has moved up or down, for example
• Ensure your content follows best practices: helpful, reliable and people-first, aligned with E-E-A-T guidelines (the fundamentals still apply here)
• Evaluate Core Web Vitals & page speed across the site
