Key Takeaways

1. Proactive Beats Reactive

Sites that scramble to fix issues after an update rarely recover quickly. Our 6-month preparation period allowed us to address vulnerabilities systematically.

2. Quality is Non-Negotiable

Every piece of content must provide genuine value. We removed 20% of our pages, but the remaining 80% were significantly stronger.

3. Diversification Matters

Our multi-channel approach (YouTube, social proof, PR) created signals Google couldn't ignore.

4. Technical Excellence is Table Stakes

Without a solid technical foundation, even the best content strategy will fail. Core Web Vitals and crawlability are fundamental.

The Bottom Line

Surviving Google's core updates isn't about luck—it's about preparation, quality, and a commitment to serving users first. By focusing on these principles months before the update, we didn't just maintain rankings; we strengthened our client's competitive position for years to come.
