What is page speed?
Page speed is how long a page takes to become usable for a real visitor — not only when the server answers, but when the main content is visible and a button responds to a tap. It is always measured on a particular device and connection, so one page can be fast on office wifi and slow outdoors.
Why it matters to a shop
The moment that decides this is not in your office. It is a person standing on the street who tapped your link from a map result on mobile data. Three seconds of blank white screen and they press back and open the next shop on the list — and they never appear in any report as a lost customer, because they never arrived. The usual cause is not exotic: photos. A picture straight off a phone camera can be six megabytes, and eight of them on the home page is enough on its own to make a small business site feel broken on a phone.
How to test it, and what to fix first
- Test the address the public actually visits — the published URL, not the editor preview, which loads from your own machine under conditions no customer has. Run it through Google PageSpeed Insights and read the Mobile tab, because that is where nearly all of your visitors are.
- Resize photos before you upload them. A full-width image rarely needs to be wider than about two thousand pixels, and an ordinary phone photo is often ten times the file size it needs to be. This one step fixes more small-business sites than everything else put together.
- Count what loads on the first screen: an embedded map, a background video, a chat bubble, three different fonts. Each is a separate download competing with your own content. Remove the ones no customer ever asked for, publish again, and re-test the same URL.
Common mistake: Two mistakes with one root, which is measuring the wrong thing: judging speed from your own desktop, on fast internet, on a page your browser has already cached — and chasing a perfect score. The score is a proxy; what matters is whether someone on a phone sees your content and can tap the button. Speed affects whether people stay, but no score buys a position in search results.
