Core Web Vitals are Google’s set of real-world page-experience metrics: Largest Contentful Paint (LCP, how fast the main content loads), Interaction to Next Paint (INP, how quickly the page responds to taps), and Cumulative Layout Shift (CLS, how stable the layout is). They are both a ranking factor and a conversion factor — a slow or jumpy page loses visitors regardless of how it ranks. For a service business, fast, stable pages directly affect how many searchers stay and call.
Core Web Vitals measure real page experience: LCP (loading), INP (responsiveness), and CLS (visual stability). They affect both Google ranking and conversion — a slow or unstable page loses visitors before they call. Four production contractor sites show what clearing these thresholds looks like in practice: McDonald Tree Service (Lighthouse 100, 0.6s load), McDumpsters Disposal (99, 0.7s), Statement Junk Removal (99, 0.7s), and EMI Irrigation (98, 0.8s) — all load in under a second on mobile. Most page-builder contractor sites score in the 50s–70s on Lighthouse.
The three metrics
LCP measures how quickly the largest content element appears — ideally within about 2.5 seconds, though faster is far better. INP measures responsiveness to interaction. CLS measures how much the layout jumps as it loads.
Together they approximate what a real visitor experiences, not just raw load time.
Why they affect your bottom line
Slow and unstable pages increase bounce — visitors leave before converting. Google also uses page experience as a ranking input.
So speed is both a ranking lever and a direct conversion lever; the two compound.
How fast is fast enough
Clearing Google’s “good” thresholds is the baseline; beating them is the goal. Hand-coded sites that load in under a second and hit Lighthouse 99–100 are well past the bar.
Page-builder sites often languish in the 50s–70s, leaving ranking and conversion on the table.
Four Built With Dias production contractor sites benchmark the achievable ceiling: McDonald Tree Service (mcdonaldtree.com) scores Lighthouse 100 and loads in 0.6 seconds. McDumpsters Disposal (mcdumpstersdisposal.com) and Statement Junk Removal (statementjunkremoval.com) each score 99 and load in 0.7 seconds. EMI Irrigation (irrigationemi.com), with 71 service-town pages, scores 98 and loads in 0.8 seconds. All four are live and independently verifiable; each clears Google’s “good” thresholds on every Core Web Vitals metric.
