The most common questions already have a published answer, with the evidence attached.
Buying decision
Not sure the audit is the right tool?
DIY, monitoring, a consultant or this — compared honestly, including when not to buy.
Deliverable
What exactly do you receive?
The pipeline end to end: evidence, adjudication, fixes, and the verification re-runs.
Business case
What could faster pages be worth?
Estimate it from your own real-user field data, not a generic multiplier.
Lab vs field
Lighthouse and Core Web Vitals disagree?
When a high lab score does — and does not — predict a real-user pass.
Before / after
Is that improvement real?
How many Lighthouse runs it takes to prove a change, at 95% confidence.
Client work
Auditing sites for clients?
The white-label programme usually fits better than volume pricing.
Each of those is published with its data and its method — the sample-size rule comes from how many Lighthouse runs prove a change, and the rest of the studies are in the research index.
