Google March Core Update: Essential Things You Need to Know

The Google March core update has begun rolling out officially, marking another significant shift in how the world’s biggest search engine ranks web content. According to an announcement posted on the Google Search Status Dashboard, the update started at 9:23 AM PDT (or 4:23 PM in the UK) on March 13, 2025, and is expected to take up to two weeks to fully deploy across all of Google’s search systems.

While the search giant has not provided specific details on the changes, past updates suggest that rankings across various industries could experience notable shifts. Here’s what SEO professionals, marketers, and website owners need to know to navigate this latest update.

What Are Core Algorithm Updates?

Core algorithm updates are broad and fundamental changes to Google’s ranking systems. Unlike minor updates that target specific issues, such as spam or page experience, core updates can significantly impact search rankings across the web. These updates aim to refine how Google assesses content relevance, authority, and quality.

During core updates, some websites see a boost in rankings, while others may experience a decline. These fluctuations are expected and typically stabilise after the update is fully rolled out.

How This Update Affects Search Rankings

If history is any indication, the March 2025 core algorithm update will likely:

• Improve rankings for websites with high-quality, authoritative content.
• Penalise sites with outdated, thin, or low-value content.
• Adjust rankings based on new interpretations of search intent and relevance.

Since Google has not shared explicit ranking factor changes, site owners and SEO professionals must rely on best practices to maintain or improve their search visibility.

Steps to Adapt to the March 2025 Core Update

While no immediate action is required, monitoring and adjusting your SEO strategy can help mitigate negative effects and capitalise on potential ranking improvements. Consider the following best practices to ensure your website is ready for the Google March core update:

1. Monitor website performance

Check Google Analytics and Google Search Console regularly to track any shifts in traffic, impressions, and keyword rankings. Look for:

• Sudden drops or increases in organic traffic.
• Changes in ranking positions for high-priority keywords.
• Shifts in user engagement metrics (e.g., bounce rate, time on page).

2. Evaluate content quality

Google’s core updates consistently prioritise content that is:

• Helpful and valuable to users.
• Well-researched and backed by authoritative sources.
• Up-to-date with accurate information.
• Written with clear, concise language.

If rankings drop, review affected pages and assess whether the content aligns with Google’s E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) guidelines.

3. Strengthen onpage SEO

Ensure that fundamental onpage SEO elements are optimised, including:

• Title tags and meta descriptions – keep them compelling and relevant to search queries.
• Header tags (H1, H2, H3) – use clear, descriptive headings that organise content effectively.
• Keyword Optimisation: Avoid keyword stuffing; focus on natural and user-centric content.
• Internal linking – link to relevant pages within your site to enhance navigation and authority distribution.

4. Improve technical SEO

Technical SEO remains a key factor in ranking performance. Ensure that you optimise:

• Page speed – faster websites improve user experience and rankings.
• Mobile usability – ensure your site is mobile-friendly, as Google prioritises mobile-first indexing.
• Structured data – implement schema markup to enhance how Google understands your content.

5. Build high-quality backlinks

Backlinks from reputable sources reinforce your website’s authority. Avoid low-quality link-building tactics and focus on acquiring natural links through:

• Guest blogging on industry-relevant sites.
• Creating link-worthy content, such as in-depth guides and original research.
• Engaging with influencers and authoritative figures in your industry or niche.

SEO Best Practices Moving Forward

With each core update, Google continues to refine how it ranks content, making it essential for website owners to prioritise sustainable SEO practices. Here are key takeaways to future-proof your site:

• Create value-driven content – focus on user intent and provide solutions that meet their needs.
• Stay updated with SEO trends – follow Google’s official announcements and industry discussions.
• Adopt a long-term SEO strategy – avoid chasing short-term gains; instead, invest in quality content and ethical SEO techniques.
