Let’s Dive In: PageSpeed Insights vs GTmetrix

 

 

What Are PageSpeed Insights?

PageSpeed Insights (PSI) is Google’s free tool that measures how well your website performs.

On both desktop and mobile devices. It provides:

• Real Core Web Vitals data

• Performance scores from 0 to 100

• Actionable suggestions using Lighthouse

• Insights based on real user data (field + lab)

---

What is GTmetrix?

To begin with, GTmetrix is another free tool that analyses your website’s loading performance.

It’s popular for its waterfall charts, test server options, and visual reporting.

It uses the same Lighthouse engine as PSI (for its performance score),

But not always with the same depth.

Why PageSpeed Insights Wins (Especially for SEO)

1. It’s Google’s tool.
   When Google itself gives you speed scores and SEO suggestions, you’d be mad not to pay attention.

2. PSI shows you exactly what Google cares about.

3. It reports real-user metrics.
   On the other hand, GTmetrix only runs synthetic tests. However, PSI utilises browsing data from Chrome users everywhere. (CrUX), which is what Google uses to rank websites.

4. It’s fully mobile-first.
   Google ranks mobile pages first. GTmetrix’s free version doesn’t even test mobile unless you pay. That’s a big deal.

5. It directly ties into Core Web Vitals.
   PSI shows LCP, FID (or INP), and CLS scores in an easy-to-read layout.

6. These are ranking factors. GTmetrix shows them, but PSI is the source.

We used these to get our results. (Look at our live results in the main menu.)

So, Should You Still Use GTmetrix?

GTmetrix is helpful for:

• Waterfall loading breakdowns

• Testing from different countries

• Seeing resource-level issues

It’s a good companion tool, but if you’re trying to rank higher on Google,

It just makes sense to prioritise Google’s insights.
