An original planning guide. Use the linked primary documentation for platform details and the supported procedure for your environment.
Choose representative pages
Include the main entry page, a content-heavy page, and a critical interaction such as search or product selection.
Record test conditions
Note device profile, network settings, URL, environment, and whether caches are warm or cold. Keep comparisons as consistent as practical.
Separate the evidence
Record available field measurements separately from controlled lab runs. Include failures, missing coverage, and the specific metrics under review.
Keep a visual and functional check
Watch loading and interaction behavior alongside numbers. A faster result that breaks content or controls is not an acceptable improvement.
Worked scenario
See the plan in practice.
A cached desktop homepage and an uncached mobile product page are different tests. Label both rather than treating their scores as interchangeable.
Review your result
Your acceptance checklist
Pages representative
Conditions recorded
Functionality checked
Use these checks to identify gaps in your repeatable baseline report. Assign an owner to any unresolved item before the next dependent step.
