Let’s start with a thought: a Google PageSpeed score is like a first date. It’s great, and it gives you a general vibe—but it doesn’t always tell you everything going on under the hood. And it skews toward, well, Google.
You want a real performance audit? One that tells you what’s slowing down your site, what’s worth fixing, and what’s just a bunch of technical fluff? You’ve come to the right nerds.
At RPS, we don’t just chase numbers. We dig into the guts of your site to figure out what’s actually causing problems—and how to fix them.
So, What Is a Website Performance Audit?
It’s a full breakdown of how your site performs in the real world. Not just how it scores on a test, but how fast it loads, how stable it is, and whether your visitors are having to fight a digital boss battle just to reach your contact form.
Key Metrics We Look At:
- Time to First Byte (TTFB) – How fast your server responds.
- First Contentful Paint (FCP) – How quickly something (anything!) shows up.
- Largest Contentful Paint (LCP) – When the main stuff is fully visible.
- Cumulative Layout Shift (CLS) – Does your content jump around like it’s had too much coffee?
- Time to Interactive (TTI) – How fast your site actually lets people use it.
The Tools That Matter
Sure, you can use Google PageSpeed—but we pair it with some real-deal diagnostics.
Enter: WebPageTest.org. This is our favorite tool for good reason.

Why? Because it shows things like:
- Waterfall charts (what loads when, and what’s hogging the party)
- Visual load progress (how your site actually appears to users)
- Global testing locations (how your site performs around the world)
We also like:
- Lighthouse reports for technical flags
- GTmetrix for quick breakdowns
- Chrome DevTools for in-depth code-level audits
Each tool gives us a different lens to look through—and together, they tell the full story.
What’s Slowing Down Your Site?
Here’s where it gets spicy. Common culprits include:
- Oversized images (because your homepage doesn’t need a 12MB PNG)
- Poorly coded themes or page builders
- Too many plugins doing the same job
- No caching, or the wrong kind
- Third-party scripts running wild in the background (hello, chatbots and trackers)
What We Actually Fix First
Every site’s different, but generally we look for:
- Quick wins – Compress images, enable caching, clean up scripts
- Structural issues – Is your theme bloated? Are you loading 14 fonts for no reason?
- Server-side problems – Bad hosting? Slow TTFB? Let’s talk migration.
- Mobile problems – Because your site should work everywhere, not just on desktop.
TL;DR? Here’s Your Audit Game Plan
- Don’t just look at your PageSpeed score.
- Run your site through WebPageTest and Lighthouse.
- Identify bottlenecks using waterfall charts.
- Prioritize changes that improve real user experience.
- Fix the easy stuff. Then tackle the big stuff.
- Still stuck? That’s why we exist.
