Navigation AI is Uxify’s optimization layer that makes website navigations feel instant. It uses the Speculation Rules API together with our own AI engine, which learns from visitor behavior and your site’s historical data. The result is faster page transitions improving your site’s performance.
How Navigation AI works?
Navigation AI predicts the next page your visitor is most likely to open. It then preloads that page in the background so it’s ready by the time they click.
It does this by combining:
Real-time visitor behavior – analyzing how users move on your site.
Historical traffic data – learning from past navigation patterns.
Speculation Rules API – the browser feature that enables safe preloading.
This approach ensures that preload activity is targeted and efficient, giving the visitor a faster experience without unnecessary resource usage.
How to install Navigation AI?
Navigation AI is included automatically when you install the Uxify snippet.
No separate setup is required.
Once the snippet is added, Navigation AI can start analyzing visitor flows and optimizing navigations.
Dashboards in Navigation AI
Inside the Uxify app, the Navigation AI section gives you a full overview of its impact. You’ll see several dashboards:
Instant experience
Shows the percentage of navigations predicted and optimized by Navigation AI. Results are broken down into:
Truly instant – navigations under 300ms.
Semi-instant – navigations between 300ms and 1s.
Faster pageload – navigations above 1s but still faster than normal.
This gives you a clear view of how often your visitors experience an instant site.
Experience wins
Compares Core Web Vitals (CWV) for optimized vs. standard navigations, such as:
LCP (Largest Contentful Paint) – speed of loading
INP (Interaction to Next Paint) – speed of interaction
CLS (Cumulative Layout Shift) – visual stability
TTFB (Time to First Byte) – server response time
For example, you may see LCP reduced from ~2s to 0.3s on optimized navigations.
Engagement wins
Shows how performance improvements affect behavior:
Time to engage – how quickly users interact after a page loads.
Prevented loading exits – sessions saved from users leaving too early.
Pageviews per session – how faster journeys encourage deeper engagement.
Settings
Configure how Navigation AI runs:
Optimization mode – choose between Eco (efficiency) or Max (maximum preloading).
Excludes – remove specific URLs from optimization (useful for sensitive or dynamic pages).
Why it matters?
Navigation AI bridges the gap between performance engineering and user experience. By turning predictive intelligence into real speed gains, it improves Core Web Vitals, reduces exits, and drives higher engagement.
