During rollouts like this, rank tracking platforms often show elevated volatility as results shift in waves. Google also recommends waiting at least a week after a core update finishes before analyzing performance in Search Console. Source: Google Search Central

Who gained visibility and why

Brands and specialized sites showed gains in “best of” queries

Early analysis highlighted more brands and category specialists winning visibility for “best of” style searches, where people are comparing options and narrowing down choices. Source: Search Engine Journal

General publishers saw stronger volatility signals

Reporting also noted volatility across multiple surfaces for broader publishers, which reinforces a long-term pattern. Specificity and credibility tend to outperform generic coverage over time, especially after core updates. Source: Search Engine Journal

What this means for local and service businesses

What should a local business do after a core update

Focus on fundamentals that reduce ambiguity. Make it obvious what you do, where you do it, and why you are credible. Core updates tend to reward clarity and usefulness, especially on service pages and location-intent searches.

What matters most for local visibility right now

• Clear service pages that match real customer intent
• Consistent business information across your site and listings
• Google Business Profile activity that shows you are active and available
• Credibility signals like reviews, photos, and real examples of work
• Structured data that helps search engines understand your business

AI search best practices to follow now

Write for direct answers

Use clear headings, short paragraphs, and direct responses. AI systems and featured snippets tend to prefer content that answers questions quickly and consistently.

Build topical focus instead of “everything” pages

If you offer multiple services, give each primary service its own page. Avoid trying to rank one page for every topic. Core updates often reward sites that demonstrate clear category expertise. Source: Search Engine Journal

Use structured data to reduce confusion

LocalBusiness and Service schema help search engines and AI systems connect your brand to your services and location. This does not guarantee rankings, but it improves machine-readability and consistency.

Keep internal linking simple and intentional

Link from blogs to the most relevant service page. Link between related services. This helps users and crawlers understand priority pages and relationships.
