Reduce INP Score — Without Re-launching Your Site
Measurable Lighthouse uplift, gated by CI so it sticks
What you're seeing
INP is bleeding north of 200ms and your interactive components feel laggy after the first paint.
Our approach
We isolate the long tasks, break up the main thread, and rewrite the worst hot-paths with proper scheduling. INP lands below 100ms across the 75th percentile.
Symptoms teams come to us with
- Lighthouse and PageSpeed scores stuck in the red on mobile
- Visitors bounce before the hero or content paints
- Search Console flags Core Web Vitals as "Poor" on key URLs
- The site feels fast on your laptop but crawls on real phones
What we check first
- 01Oversized JavaScript bundles and unused third-party SDKs
- 02Render-blocking CSS, fonts and tag-manager scripts
- 03Unoptimised images and a missing modern image pipeline
- 04Slow TTFB from cold starts, slow queries or chatty APIs
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
RUM-driven audit with line-level fix list
Implementation of every critical fix
Before/after metrics with screenshots
CI performance gate to prevent regression
From brief to shipped fix
A transparent, low-risk process — a senior engineer reads your brief personally, and nothing starts until you approve a written plan and price.
Diagnose
A senior engineer reviews your brief, reproduces the issue, and pinpoints the real root cause — not the symptom — before any code is touched.
Scoped plan & quote
You get a written plan to reduce INP Score, a firm timeline, and a fixed quote. Nothing starts until you approve it — no surprise invoices.
Ship the fix
We implement on a branch and open a pull request you review, working to your code-review standards on your repo — never a black box.
Verify & hand off
We verify on staging and production, share before/after evidence where it applies, and leave you a short hand-off note so the fix sticks.
Why teams hand this task to Krapton
Senior engineers only
Your brief is read and handled by a senior engineer — no junior hand-off, no sales-rep filter in between.
Root cause, not a patch
We reproduce and fix the underlying cause, then add a guard so the same class of issue does not quietly return.
Your repo, your standards
Every change lands as a pull request you review, on your repository, following your existing review process.
NDA on day one
Confidentiality and IP are covered before we look at a single line of code. All work stays in your accounts.
Fixed quote up front
You approve a written plan and price before work starts. If scope changes, we re-quote in writing — no surprise invoices.
Proof, where it applies
Performance, SEO and reliability work ships with before/after evidence so the result is measurable, not anecdotal.
Three ways to engage

Reduce INP Score — your questions, answered
How much does it cost to reduce INP Score?
Pricing starts from $1,500 and depends on the scope we find during the diagnostic. You get a fixed, written quote before any work begins — most engagements like this run 1–2 weeks.
How long does it take to reduce INP Score?
Typically 1–2 weeks for a focused engagement. After a short diagnostic we commit to a firm timeline so you know exactly what to expect.
Will you work directly on our existing codebase?
Yes. We work on your GitHub, GitLab or Bitbucket, ship every change as a pull request you review, and follow your code-review standards — not ours.
What exactly will I have at the end?
Concrete, documented outcomes — RUM-driven audit with line-level fix list, Implementation of every critical fix, Before/after metrics with screenshots, and more. No black-box agency report.
How quickly can you start, and do you sign an NDA?
For a focused task like this we can usually start within 24–48 hours of the brief. We sign an NDA on day one, before we look at any code — yours or ours.
Will this improve my Core Web Vitals and Google rankings?
Directly. We fix the metrics Google actually ranks on — LCP, INP and CLS — on real-user data, then lock the gains in with monitoring so they don't regress. Better field metrics typically support better rankings on competitive queries.
