| Metric | Good | Fix |
|---|---|---|
| LCP | <2.5s | Optimize hero image |
| INP | <200ms | Reduce JS |
| CLS | <0.1 | Set image dimensions |
Google uses mobile Core Web Vitals for ranking — always audit on throttled mobile.
LCP element is usually the hero image — optimize it first for the biggest impact.
Lighthouse, WebPageTest, and PageSpeed Insights are free and cover most audit needs.
Crucial code requirements, material risk alerts, and prevention checklists for Website Performance Audit Guide.
⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
