What is TTFB by Navigation AI impact
TTFB by Navigation AI impact breaks down Time to First Byte (TTFB) split by whether the page was delivered via a standard or an AI-optimized navigation.
TTFB generally reflects backend responsiveness, but Navigation AI can indirectly affect it — especially when prerendering removes cold starts or when speculative preconnects warm up the server path.
This lens is useful for understanding how AI-assisted routes affect the initial server handshake and how that contributes to the overall perceived speed.
Type | Description |
Standard navigation | A typical page load (e.g. link click or hard reload) with no AI enhancements |
Optimized navigation | A prerendered or AI-predicted page load using Navigation AI |
Healthy TTFB by Navigation AI impact sample
Should you worry
If both Standard and Optimized navigations have fast TTFB values, you’re in good shape. Navigation AI may still improve the rest of the load path, but server-side latency isn’t the issue.
Unhealthy TTFB by Navigation AI impact sample
When Standard navigations show higher TTFB:
Cold cache or connection states are slowing down the backend
DNS, TLS, or routing latency is hurting first-byte timing
AI preconnects and prerendering give Optimized pages a noticeable edge
If Optimized navigations somehow show slower TTFB:
There may be misconfigured prerender routes or prediction gaps
Navigation AI might be attempting prerenders but getting blocked (e.g. by cookies or auth)
Resolving unhealthy TTFB by Navigation AI impact
Go-to action plan to resolve an unhealthy TTFB by Navigation AI impact:
Ask Uxi to analyze your TTFB by Navigation AI impact values and suggest improvements.
Use Filters to isolate slow sessions by page, region, or route.
Simulate TTFB of the suspected lens to see if fixing it will resolve the TTFB by Navigation AI impact. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by Navigation AI impact values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
