How to Tell If Your Website Is Too Slow — and What It Actually Costs

Speed is the most expensive website problem almost nobody measures. It has no error message and no warning email — visitors simply leave, and you never hear about the ones who did. Here is how to find out where you stand in about a minute, and what the number means in customers.

The one-minute test

Turn your phone off Wi-Fi so you are on cell data, the way a customer standing outside your shop would be. Open a private or incognito tab so nothing is cached. Type your web address and count out loud until the words appear.

Under two seconds is good. Two to four is where people start bailing. Past five, most of them are already looking at whoever came second in the search results — and they never knew what they missed, so they never tell you.

Do the same test on the competitor who ranks above you. That comparison is usually more persuasive than any report, because it removes the excuse that "everybody's site is like that."

Why it is almost always the builder

On a page-builder site — Wix, Squarespace, GoDaddy, a heavy WordPress theme — your words are the last thing to arrive. First comes the builder's own framework, then the theme, then the plugins, then the fonts, then the tracking scripts, and only then the sentence a customer came to read.

That is not a setting you can switch off, because it is the product. It is why an identical-looking page built by hand can answer in a fraction of a second while the builder version takes six.

Images are the second cause. A photo straight off a phone can be four megabytes; on the web it should be under two hundred kilobytes and no wider than it displays. Ten unresized photos on a homepage will sink any site, however it was built.

What slow actually costs

Google has used page speed as a ranking signal on mobile for years, so slow costs you position before it costs you visitors. Then it costs you visitors: the longer a page takes, the more people abandon it, and the effect is steepest in the first few seconds.

Put it in your own numbers. If your site brings in four jobs a month and a third of your visitors leave before it loads, you are not losing "traffic" — you are losing roughly one job a month, every month, quietly.

The fix is rarely a redesign. It is usually the same page, rebuilt as plain fast code, with the images sized properly and the tracking trimmed to what you actually read.
