Core Web Vitals Optimization
LCP, CLS, INP fixes that move your PageSpeed scores into Google's "good" thresholds. Real before/after measurements. No "we improved your score" without numbers.
Google's Core Web Vitals are a ranking signal and a UX signal. Most NJ business websites fail at least one of LCP, CLS, or INP. We diagnose what's actually slow (it's rarely what you think) and fix it without the "we rewrote your CSS for no reason" agency pattern.
One accountable partner, fast decisions, and a premium result that looks expensive and feels simple. We confirm scope, build fast, and ship.
The three Core Web Vitals, in plain English
LCP — Largest Contentful Paint. How long until the biggest visible thing (usually the hero image or heading) appears on screen. Target: under 2.5 seconds on a mobile 4G connection. Most NJ business sites are at 4–7 seconds. Common culprits: unoptimized hero image, render-blocking CSS, font loading strategy.
CLS — Cumulative Layout Shift. How much the page jumps around as it loads (when an image loads and pushes the rest of the content down, that's CLS). Target: under 0.1. Common culprits: images without dimensions, ads loading late, fonts swapping in.
INP — Interaction to Next Paint. How long it takes the page to respond when someone taps a button. Target: under 200ms. Common culprits: heavy JavaScript on tap handlers, third-party scripts blocking the main thread, animation jank.
Our process: (1) Pull your 28-day Chrome User Experience Report data (field data — real visitors, not lab); (2) Run Lighthouse and WebPageTest for lab data and waterfall analysis; (3) Identify the specific 3–5 issues causing your failures; (4) Fix them with targeted changes (no full rewrites); (5) Verify with both lab and field data 28 days post-fix.
What we don't do: full rewrites of working sites to get a Lighthouse score, ad-server removal without your business justification, "we cleaned up your CSS" without measurable improvement.
Frequently Asked Questions
How much does Core Web Vitals optimization cost?
Audit + fix list: $497 (typical 1-page site) to $1,997 (typical multi-page site). Implementation: $1,500–$5,000 depending on issue type. Audit + implementation: $2,500–$6,500.
Can you get my Lighthouse score to 100?
No. Per our standing policy, we don't commit to literal 100/100/100/100 on content-rich pages. Realistic targets are A+ (90–97) across the four Lighthouse categories. The "good" Core Web Vitals thresholds (LCP <2.5s, CLS <0.1, INP <200ms) are achievable; perfect 100 scores often aren't and aren't the same as fast in real-world data.
How fast will the field data update?
28 days — CrUX uses 28-day rolling data, so field metrics update fully 28 days after the fix lands.
Will this help SEO?
CWV is a ranking signal, so passing all three thresholds removes a negative signal. It's not a magic ranking boost, but it removes one of the few signals Google has confirmed as a direct ranking input.
What about images and fonts?
Both are the most common CWV failure sources. Image fixes (proper srcset, WebP/AVIF format, lazy-loading, dimensions) are usually highest-leverage. Font fixes (font-display swap, preload critical font) are second.
