I Thought My Website Was Fast Enough
For a long time, I assumed my website was reasonably fast.
It opened quickly on my laptop, so I didn't think much about it.
Then I started testing individual pages properly.
The results were different from what I expected.
Some pages were carrying oversized images, unnecessary scripts, and older template elements that I simply hadn't noticed.
That experience changed how I approach page speed.
Why I Check Mobile Performance
A website can feel perfectly fast on a modern laptop with a strong internet connection.
That's not the experience everyone has.
Mobile devices vary.
Connections vary.
Users may be on slower networks or older hardware.
That's why I pay particular attention to mobile performance when auditing a site.
It also connects directly with the mobile usability issues I covered in [Reason #2 — Your Site Isn’t Mobile-Friendly Enough].
The First Tool I Open
My first stop is usually Google PageSpeed Insights.
I use it to identify performance opportunities and look at the Core Web Vitals-related information.
I also check Google Search Console for site-wide patterns rather than looking at one URL in isolation.
I'm not trying to get a perfect score.
A score is useful, but understanding why a page is slow is much more valuable.
The Biggest Speed Problems I Usually Check
The first thing I inspect is images.
Large, unoptimized images can add a surprising amount of page weight.
Then I look at:
- Unnecessary JavaScript
- Too many third-party scripts
- Bloated themes or templates
- Poor caching
- Render-blocking resources
- Excessive plugins
- Fonts and other external resources
I don't automatically remove something just because a tool flags it.
I check whether it actually contributes to the page and whether removing or changing it could cause other problems.
What Actually Made a Difference for Me
On the pages I worked on, image optimization made one of the most obvious differences.
I also removed scripts that weren't being used and cleaned up older template elements.
The result wasn't just a better test score.
The pages felt better to use.
That's the outcome I care about most.
Don't Treat Speed as a Magic Ranking Button
This is an important distinction.
Improving page speed doesn't guarantee that a page will suddenly jump to the top of Google.
Search rankings depend on much more than performance.
But a slow, frustrating website is still something I'd rather fix than ignore.
If you're diagnosing a website from scratch, I'd start with [Technical Reasons Your Website Isn’t Ranking on Google], then check indexing, mobile experience, and speed together.
