The Problem

Your Site is Bleeding Money

Every second your site takes to load is costing you visitors, customers, and rankings.

40%

The "Screw This" Threshold

That is the percentage of people who click away if your site takes more than three seconds to load. You're working hard for traffic just to let it walk out the front door because your images are too chunky.

1st Page

The Ghost Town

90% of traffic never leaves the first page of Google. Since the 2024 Core Update, sites with red "Vitals" scores are being pushed to page two. That's effectively being buried alive in the search results.

The Three Metrics That Matter

The Core Web Vitals Clinic

Forget the waterfall charts and jargon soup. These three numbers decide if Google loves your site or buries it on page 47. We don't just measure them — we tell you exactly what's broken and how to fix it.

Loading Speed

LCP — Largest Contentful Paint

The "Show me the money" metric. How long until users actually see your main content? If your hero image is a 4MB PNG from 2015 or you're loading fonts from a server in Antarctica, your LCP is toast. We find the bandwidth hog and tell you exactly how to compress it.

Visual Stability

CLS — Cumulative Layout Shift

The "why did I just click that ad" problem. User goes to tap "Buy Now" but an ad loads at the last millisecond and — boom — they clicked the ad instead. Rage ensues. Conversions die. We pinpoint the exact element playing musical chairs with your layout.

Responsiveness

INP — Interaction to Next Paint

The new kid that replaced FID in 2024. Measures how "snappy" your site feels when people click things. If your menu takes a half-second to open, users think their phone is broken. Usually it's a rogue analytics script or a bloated plugin hogging the CPU. We find it.

FAQ

Questions We Get A Lot

Why lab data instead of field data?

Because the internet is a chaotic place. Your score depends on server load, your own internet speed, and even the weather (okay, not the weather, but close). VitalsFixer uses lab data to give you a stable, scientific baseline of what's actually happening under the hood.

Is this better than GTmetrix?

GTmetrix is fine if you want to spend four hours looking at waterfall charts. But if you want a tool that says, "Hey, your header image is 3MB, make it 100KB," that's us. We prioritize actions over graphs. We're the fixer, not the librarian.

Do I need to know code to fix these issues?

Nope. Most fixes are simple: compress images, defer scripts, use a CDN. We give you the exact steps. If you can copy-paste, you can fix 80% of what's wrong.

How do I actually fix my Core Web Vitals?

First, run a scan here. We'll give you a punch-list. Usually, it's about compressing images, deferring non-essential scripts, and making sure your server isn't running on a potato. It's not magic, it's just physics.

Will this actually improve my Google rankings?

Yes, but not overnight. Core Web Vitals are a ranking factor, especially since the 2024 Core Update. Fix your vitals, and you'll see improvements in bounce rate, conversion, and search visibility over time.

How much does it cost to fix Core Web Vitals?

Checking is free — the analyzer costs nothing and needs no signup. Fixing depends on the route: the DIY guide is free, and the done-for-you Expert Fix starts at $99 one-time for up to 5 pages ($149 or $349 monthly if you want us on retainer). Fixes ship in 48 hours, money-back guarantee included.

What counts as a passing score in 2026?

Google's bar: LCP under 2.5 seconds, CLS under 0.1, INP under 200 milliseconds — all measured from real Chrome users at the 75th percentile. Pass all three and you're green. Miss one and the whole page fails the assessment. Harsh, but at least it's clear.

Does this work with WordPress and Shopify?

Yes. The analyzer takes any public URL, whatever it runs on. The Expert Fix service covers WordPress, Shopify, React, Next.js, Vue, and hand-rolled custom code. The method is the same everywhere: find the exact image, script, or setting that's slow — fix that.
