The short answer: the main part of the page should be on the screen within 2.5 seconds. That’s the line Google draws for a good result. Between 2.5 and 4 seconds it calls “needs improvement”, and past 4 seconds “poor”.
The measure is called Largest Contentful Paint. In plain terms it’s the moment a customer can see the thing they came for: your headline, your photo, your phone number. It’s not when every last script has finished, and it’s not when the address bar stops spinning.
What local websites actually do
In September we loaded 89 Casey and Cardinia business websites the way a customer’s phone does: plumbers, electricians, landscapers, roofers, physios, podiatrists, chiropractors and dentists in Berwick, Cranbourne, Narre Warren and Pakenham. 85 of them could be timed.
- The middle site took 8.4 seconds to show its main content. That’s more than three times Google’s line.
- 2 of the 85 made it inside 2.5 seconds. Both were trade sites. No clinic did.
- 35 of the 85 took longer than 10 seconds.
- By trade, the middle times ran from 7.3 seconds for plumbers and 7.5 for physios up to 10.1 for podiatrists and 12 for dentists.
- The suburb made little difference: Narre Warren 8.1 seconds, Berwick and Cranbourne 8.4, Pakenham 9.1.
The test was Google’s Lighthouse on its mobile setting, which imitates a mid-range phone on a slowed-down 4G connection. A customer on strong Wi-Fi will see a site sooner than that, and one on a weak signal in a car park later. It’s the same test Google’s own PageSpeed Insights runs, so the numbers compare fairly. The method and every figure are in the study.
Does a few seconds matter?
Picture how the customer got there. They searched “plumber Pakenham” or “physio near me”, and there are three or four results on the screen. They tap one. If it’s still white after a few seconds, the back button is right there and so are your competitors.
You won’t see those people anywhere. A visit that gives up before the page shows usually doesn’t appear in your analytics at all, and nobody rings to say they left.
Speed isn’t the whole story. A fast site with no way to call is still a dead end, so it’s worth testing your call button while you’re at it. But a site nobody waits for never gets the chance to do anything else.
Test yours in two minutes
- Go to PageSpeed Insights on a computer and paste in your home page address.
- Make sure the Mobile tab is selected. The desktop score flatters almost everyone.
- Find Largest Contentful Paint in the lab results. Under 2.5 s is good. Over 4 s means customers are waiting.
- If a panel headed “Discover what your real users are experiencing” shows figures, that’s data from real Chrome visitors. Most small business sites don’t get enough visits for it to appear, which is normal.
Run it two or three times. The number moves around by a second or so between runs.
What usually slows a small business site
These are the causes we see most often when we pull a slow page apart. They’re not figures from the study.
A huge photo at the top. A hero image straight off a phone camera can be several megabytes. The page can’t show its main content until that picture arrives. The middle site in our study weighed 2.2 MB in total; clinic sites were heavier than trade sites at 2.7 MB against 2.0.
A slider or video in the header. Three large photos that rotate often cost three downloads before the first one settles.
Page builders and plugins. 62 of the 89 sites in the study were built on WordPress. That isn’t slow by itself, but each plugin and builder adds code that every visitor downloads, whether that page uses it or not.
Fonts. Custom fonts are files too, and the page often waits for them before it shows any text.
Chat bubbles, pop-ups and tracking scripts that load before the page needs them.
Cheap or distant hosting. If the server takes a second just to answer, everything else starts a second late.
We found two of them on our own site. Our home page was taking 4.2 seconds, a “poor” result by the same test we were using on everyone else. Two oversized font files and a decorative paper texture drawn by the browser were holding up the first paint. We cut the fonts down, swapped the texture for a small image and moved the booking form to load after the page. It now shows in about 2.2 seconds.
Or have it checked for you
Our free website check reads your home page the way a phone does. In about ten seconds it tells you whether a phone can call you from it, whether it opens securely and whether a customer can ask for a quote without ringing. The phone speed result follows by email, with the same Largest Contentful Paint measure used here.
