When you start looking for a new website, one question always comes up:

How do you know if a web designer is actually good?

Portfolios can look impressive.
Sales calls sound convincing.

But the truth is that many business owners only discover problems after the website is finished.

If the site is slow, difficult to use, or performs poorly in search results, fixing it later can be expensive.

One simple way to avoid this problem is to look at the numbers.

Check the Website Performance

Every web designer has a website of their own.

That website is effectively their shopfront. If performance is poor there, it raises obvious questions about how other projects are built.

To make this easier to check, we created a simple website performance scanner.

You can enter any website address and see how it performs.

You can test:

• your own website
• a designer you are considering
• competitor websites

What the Results Mean

When you run a scan, the report focuses on a few core indicators that affect how websites perform.

Speed

Speed has a direct effect on how people use a website.

If a page takes several seconds to load, many visitors will leave before the content even appears.

Slow websites also tend to perform worse in search engines, which means fewer potential customers reaching the site in the first place.

Mobile Performance

Most people discover businesses on their phone.

If a website loads slowly on mobile devices or is difficult to navigate on a smaller screen, visitors usually leave quickly.

Testing mobile performance helps identify problems that may not be obvious when viewing the site on a desktop computer.

Technical Structure

Performance tools also highlight issues that are difficult to see from the outside.

Common examples include:

• oversized images
• excessive scripts or plugins
• inefficient hosting environments
• page builders that generate heavy code

These problems often explain why a website feels slow even when it looks visually fine.

Test Your Own Website

If you already have a website, running a scan can reveal useful information.

Many sites appear to work normally but still contain technical issues that affect performance and visibility.

A performance report can help identify:

• where loading delays occur
• whether mobile usability is affected
• what technical improvements may be worth prioritising

This can be helpful when discussing improvements with developers or planning a future rebuild.

Why the Tool Is Free

The performance scanner is free to use and only takes a few seconds to run.

The goal is simple: to make website performance easier to understand.

When businesses have clear information about how their site performs, conversations about improvements become much more practical.
