How We Hit 100/100 PageSpeed on Every Single Build

The Number That Actually Moves the Needle

Google has been direct about this for years: page speed is a ranking factor. But most business owners do not know what a bad score is actually costing them.

Here is what the data shows. A site that loads in 1 second converts 3x better than one that takes 5 seconds. A 100ms improvement in load time can increase conversion rates by up to 8%. For a service business generating 20 enquiries a month, that is potentially 1-2 extra leads every single month just from a faster website. Not from more ad spend. Not from more content. Just from removing the friction that was already there.

The average WordPress site scores between 40 and 65 on Google PageSpeed Insights. Ours score 100. Here is exactly how we get there.

Step 1: We Start With the Right Stack

Most agencies build on WordPress, Webflow, or Squarespace because they are fast to deploy for the agency. The problem is these platforms carry enormous performance baggage: plugin overhead, bloated CSS frameworks, unoptimised database queries, third-party scripts loaded on every page.

We build on Next.js with React, deployed on Vercel's edge network. This is not overkill. It means:

Before a single line of code is written, the architecture decision alone puts us 30 points ahead of the average agency site.

Step 2: Images Are Treated as a First-Class Problem

Images are responsible for the majority of page weight on most websites. We see client sites regularly carrying 4MB, 6MB, even 10MB of unoptimised imagery on a single page. Each one of those megabytes is a visitor losing patience.

Every image on our builds goes through a specific process:

This alone typically saves 60-80% of a page's total weight compared to what we inherit from a client's existing site.

Step 3: No Unnecessary JavaScript

Every script you add to a website has a cost. It has to be downloaded, parsed, and executed before the page is fully interactive. Analytics tools, chat widgets, cookie banners, third-party fonts loaded the wrong way, social share buttons no one clicks. These add up to hundreds of milliseconds of blocked rendering.

We audit every script on every build. If it is not directly tied to a conversion goal, it does not go on the page. If it does go on the page, it loads asynchronously so it cannot block the user from seeing content.

For analytics, we use a lightweight solution that adds 1KB instead of 40KB. For fonts, we self-host and preload. For anything else, we apply the same question: is this worth the performance cost?

Step 4: Core Web Vitals as a Checklist

Google's Core Web Vitals are three specific metrics that determine your PageSpeed score and directly impact your search ranking:

LCP (Largest Contentful Paint): How long until the biggest visible element loads. Target: under 2.5 seconds. We typically hit under 1.2 seconds.

CLS (Cumulative Layout Shift): How much the page "jumps" as it loads. This happens when images have no defined dimensions or fonts swap in late. We eliminate this entirely by setting explicit dimensions on all media and using font-display: swap with fallback metrics that match the loaded font.

FID/INP (Interaction to Next Paint): How quickly the page responds to a click or tap. We keep JavaScript execution minimal, so this is rarely above 50ms on our builds.

Step 5: We Verify Before You See It

Before we hand off any site, we run it through Google PageSpeed Insights, GTmetrix, and WebPageTest from three different locations. If any metric is below 100, we fix it before the call. The score the client sees on delivery day is the real score.

And if it ever drops after launch, from a new embed, a new blog post with a large image, anything, we fix it as part of our ongoing service. The 100/100 guarantee has no expiry date.

Why Most Agencies Do Not Do This

It takes longer. Optimising images, auditing scripts, fine-tuning Core Web Vitals, building on a high-performance stack from scratch. Every shortcut an agency takes saves them time and costs you performance.

We built our entire process around this because we believe a website that does not perform is not worth having. Your site is competing against every other result on Google. Speed is one of the few things that is both measurable and entirely within your control.
