If you’ve ever run your website through Google PageSpeed Insights and felt instantly stressed by a low score – you’re not alone.
Google PageSpeed Insights is one of the most commonly used tools for measuring website performance, but it’s also one of the most misunderstood.
Originally launched in the early 2010s as part of Google’s broader push toward faster, more user-friendly websites, PageSpeed Insights was designed to provide developers and site owners with a snapshot of how quickly a page loads, how responsive it feels, and what technical improvements could be made.
Today, it’s used by everyone from marketing agencies and SEO professionals to business owners and developers – mainly because speed matters. A faster website generally leads to better user experience, higher conversion rates, and improved search visibility.
But here’s the truth…
A great PageSpeed score does not automatically mean a great website.
And a poor score does not mean your website can’t rank well.
Let’s break down why.
What Google PageSpeed Insights Actually Measures
PageSpeed Insights doesn’t just test “speed” in the traditional sense. It uses a combination of lab data and real-world performance metrics to calculate a score out of 100.
Some of the key metrics include:
Largest Contentful Paint (LCP)
This measures how long it takes for the main visible content (like a hero image or headline) to load.
First Input Delay (FID)
This tracks how quickly the site responds when a user first interacts – like clicking a button or opening a menu.
Cumulative Layout Shift (CLS)
This looks at visual stability. If elements jump around while loading, your CLS score suffers.
Time to Interactive (TTI)
This measures when the page becomes fully usable, not just visually loaded.
These metrics form part of Google’s “Core Web Vitals,” which are meant to reflect user experience – but they are still only one part of the bigger SEO puzzle.
Why High Scores Don’t Always Mean Better Websites
Here’s where things get tricky.
PageSpeed Insights often rewards websites that are extremely lightweight, minimal, and stripped back.
That sounds good in theory… until you realise many real-world business websites need things like:
- Video content
- High-quality imagery
- Interactive elements
- Animations
- Embedded maps
- Booking forms
- Ecommerce functionality
A visually rich site built for conversion and branding may score lower simply because it includes more assets – even if the experience is fantastic for users.
In many cases, PageSpeed recommendations can unintentionally push websites toward being bland, overly simple, or creatively restricted.
What PageSpeed Insights Doesn’t Like (Even If Users Do)
PageSpeed is known for flagging a number of common modern website features, including:
- Large background videos
- Image sliders and galleries
- Third-party scripts (like live chat, analytics, tracking pixels)
- Embedded Google Maps
- Custom fonts and icon libraries
- Animation effects and page transitions
- Marketing tools such as popup forms or CRM integrations
- WooCommerce scripts that are essential for online stores like add to cart without the page refreshing
While these elements can impact performance, they are often critical for functionality, branding, and lead generation.
The key is balance – not elimination.
PageSpeed Scores vs Real SEO Performance
One of the biggest misconceptions is assuming PageSpeed is the ultimate SEO ranking factor.
In reality, many websites with mediocre scores still dominate Google search results because they excel in areas like:
- Content quality
- Backlinks and authority
- User intent matching
- Strong local SEO signals
- Great UX and conversion design
We regularly see sites scoring 40–60 on PageSpeed that still rank on page one for competitive keywords.
That’s because Google evaluates websites holistically – not purely based on a performance test.

At Sympley, we view PageSpeed Insights as a useful diagnostic tool – but not the sole “bible” for website success or let alone SEO for that matter.
The goal isn’t to chase a perfect 100 score.
The goal is to build a fast, functional, beautiful website that delivers results.
That’s where ongoing optimisation and support matter most, which is why our team offers dedicated WordPress maintenance service solutions to keep websites healthy, secure, and performing over time.

Final Thoughts
Google PageSpeed Insights is absolutely worth using – it highlights genuine technical improvements and helps identify performance bottlenecks.
But it should never be treated as the only measure of website quality or SEO success.
Plenty of high-ranking websites have “average” scores, because real-world performance is about much more than numbers.
A well-optimised website is one that loads quickly and converts visitors, tells your story, and supports your business goals.
