Google's Latest Update: User Experience Signals Gain Weight
Key Changes
Google's 2026 core update explicitly increased the weight of the following UX signals:
- Interaction experience: INP (Interaction to Next Paint) replaces FID as a core metric
- Content stability: Stricter CLS threshold (target <0.05)
- Perceived speed: LCP and FCP grow in importance
- User engagement: Time on page and scroll depth
How SEO Experts Should Respond
Technical optimization
- Audit and fix INP issues (target <200ms)
- Implement preloading of critical resources
- Optimize image loading (WebP + lazy loading)
Content optimization
- Strengthen content depth and originality
- Improve content structure (clear H-tag hierarchy)
- Add interactive elements (calculators, quizzes)
