SEO Trends & Tactics: What to Know from Google’s March 2025 Core Update
As Google’s first core update of 2025 begins its rollout, digital marketers are already seeing shifts in rankings, engagement patterns, and reporting tools. In this week’s SEO roundup, we’ll cover the March update’s implications, new features in GA4, and actionable ways to refine your content strategy using tools like Semrush. Plus, we’ll walk through how to speak with clients about core updates and use the changes as a strategic opportunity instead of a setback.
Top Industry Updates
Google’s March 2025 Core Update Is Live
On March 13, Google began rolling out its first core algorithm update of the year. As with previous core updates, the rollout is expected to last two weeks. So far, it appears content quality, site experience, and topical relevance are again major focus areas. SEO teams should begin reviewing client performance to detect early signs of volatility and identify opportunities for refinement.
LLMs Still Struggle with Accuracy
A recent study showed that large language models (LLMs) deliver “confidently wrong” answers in over 60% of cases. ChatGPT Search alone misattributes nearly 40% of citations, highlighting the continued importance of accurate, authoritative content on the open web.
GA4 Introduces % Change Metrics
Google Analytics 4 now displays percentage-based performance metrics directly in its detailed reports. This time-saving enhancement eliminates the need for separate calculations and allows for more efficient monthly SEO reporting.
Semrush Spotlight: The Best Performing Topics Report

Semrush’s Best Performing Topics report is an underused goldmine for competitive content strategy. It analyzes a domain’s top-performing content and groups pages by topic, revealing not just which keywords matter, but which themes are actually driving traffic and engagement.
Why It Matters:
- Discover Content Gaps: See what your competitors are ranking for that you aren’t.
- Uncover High-Intent Keywords: Focus on keywords proven to attract traffic.
- Shape Your Editorial Calendar: Build content around proven industry themes, not just search volume.
Use the Best Performing Topics Report to identify themes competitors are winning with, then develop more targeted, optimized, and engaging content on the same topics.
Talking to Clients About the March Core Update
Contributor: Maja Teagle
Core updates often come with concern from clients, especially if they notice traffic fluctuations. Here’s how to proactively manage the conversation and demonstrate your value as a strategic SEO partner.
Step 1: Communicate Early
Don’t wait for clients to ask. Let them know:
- A core update is rolling out.
- You’re monitoring the impact closely.
- You’ll provide insights and next steps as data becomes clear.
This builds trust and shows you’re proactive, not reactive.
Step 2: Audit Impacted Pages
If a client’s rankings dip, examine:
- Which pages lost traffic?
- Are there commonalities (thin content, poor UX, missing visuals)?
- Are competitors gaining traction in those areas?
Step 3: Analyze the Competition
Use Semrush or GSC to see how top organic competitors are faring. Study their top-ranking pages to compare structure, content depth, use of visuals, internal links, and UX patterns.
Step 4: Build a Game Plan
Create a revised roadmap based on your findings and meet with your client early. Highlight:
- A summary of what changed
- Evidence-based recommendations
- A refreshed project plan focused on recovery and long-term growth
Pro Tip: If the client’s content production pipeline is slowing progress, pitch content support from your in-house team or adjust the SEO scope to include content strategy and execution.
Final Thoughts
Core updates shouldn’t be feared. They should be seen as an opportunity to reassess content quality, refine strategy, and prove the value of great SEO. Staying informed, communicating proactively, and presenting a clear plan will always keep your clients aligned and confident.
