Lab tests are theater. Google ranks on field data (real user metrics), not on your PageSpeed score at 3am from a datacenter.
- CrUX field data is what Google uses.
- PageSpeed shows both — read the field data.
- INP replaced FID in March 2024.
A client's lab LCP was 1.4s (green). Field LCP was 4.2s (red). Rankings matched the field data, not the lab score.
| Tool | Lab | Field | Best for |
|---|---|---|---|
| PageSpeed Insights | Yes | Yes (CrUX) | Free, quick check |
| WebPageTest | Yes | No | Deep waterfall analysis |
| Chrome UX Report | No | Yes | Site-wide field data |
| GSC CWV report | No | Yes | Ranking-impact view |
| SpeedCurve | Yes | Yes | Enterprise monitoring |

A realistic rollout timeline
- Week 1
Scan the site, snapshot current state, agree the approval workflow.
- Week 2
Apply the first batch of critical fixes with rollback points enabled.
- Weeks 3–4
Re-crawl, verify, start attribution against GSC + AI citation logs.
- Weeks 5–8
Move to steady-state: weekly scan, weekly approval, monthly review.
Paired module: Integrations Hub
One panel for GSC, GA4, Cloudflare, Microsoft Clarity, OpenAI, Anthropic, Google, IndexNow, Bing and every internal tool — with health checks per connection. Integrations that quietly break are the single biggest source of stale dashboards and bad decisions.
- Integrations → Add connection with OAuth or key
- Run the health check — connection, permissions, quota
- Set alerting for failures
- Route data to the modules that consume it
Lab score 90 but field failing?
You have a real-world issue lab tests miss — likely INP or CLS.
How often to test?
Weekly, in GSC's CWV report.
Does WBP replace GA4?
No — WBP joins GA4 with the sources GA4 cannot see (AI citations, GSC, rank, engagement inside the CMS) so you keep GA4 as the source of truth for events.
How are API keys stored?
Encrypted at rest with a site-specific key, never exposed in the UI after save, and rotatable without downtime.
