Use representative pages
Test more than the homepage. Pick templates that reflect your actual site: long articles, archives, products, landing pages, and ecommerce flows.
Repeat tests
Run several tests under comparable conditions. Caches, network variability, server load, and third-party services can make a single run misleading.

Lab data helps debug controlled bottlenecks. Field data reflects real devices, networks, and users over time. Use both for different jobs.
Check functionality too
A faster score is not an improvement if menus, forms, checkout, consent controls, or analytics stop working. Performance and correctness are both release criteria.
