Google Core Updates Are Hitting Local Businesses Hard in 2025-2026

By InnovaAI Research1 min readSterlingsky

Google's ongoing 2025-2026 core algorithm updates are causing significant ranking disruptions for local businesses, according to research from Sterling Sky published September 30, 2026. Agencies managing local SEO clients need to audit current strategies and adjust quickly, particularly around Google Business Profile configuration.

Key Facts

01Sterling Sky's Joy Hawkins published findings on September 30, 2026 confirming Google's 2025-2026 core updates are causing significant ranking disruptions for local businesses.
02The URL linked from a Google Business Profile listing can directly influence Local Pack rankings, making location page selection a strategic decision.
03Pointing GBP listings to dedicated location pages rather than homepages is the stronger approach, especially for multi-location clients.
04Agencies should separate core update volatility from GBP configuration issues, as the two problems require different fixes.
05Local Pack visibility and organic rankings can move independently, so tracking both is necessary for accurate diagnosis.

Why does this matter for agencies?

▶Core update volatility in local search directly reduces client revenue through lost foot traffic and calls, making rapid agency response a retention issue, not just a performance issue.
▶GBP URL configuration is a low-effort, high-impact change that many agencies have never systematically audited across their client base.
▶Agencies that document baselines and show measurable recovery progress will differentiate themselves from competitors during a period of widespread local ranking instability.

What should agencies do?

Audit every local client's GBP listing URL and confirm it links to a dedicated, optimized location page rather than a generic homepage.
