Site speed and mobile: what Australian business owners should check
By Martin Soliman,
Plenty of people will open your website on a phone, often while standing somewhere else and wanting one answer: opening hours, a price, a way to book. If the page loads slowly, jumps around as it appears or hides your phone number, that moment is easily lost. This guide explains what speed and mobile quality mean in practice and what you can check yourself.
What Google measures
Google publishes three measures it calls Core Web Vitals. According to Google's web.dev documentation, these are the targets for a good experience.
- Largest Contentful Paint (LCP) measures how quickly the main content loads. It should occur within 2.5 seconds of when the page first starts loading.
- Interaction to Next Paint (INP) measures how quickly the page responds when someone taps or clicks. The target is 200 milliseconds or less.
- Cumulative Layout Shift (CLS) measures how much content moves unexpectedly while the page loads. The target is 0.1 or less.
Google also states that these thresholds are assessed at the 75th percentile of page views. In plain terms, the aim is for the large majority of visits, not just those on the newest phone and fastest connection, to meet the targets.
Why the mobile version matters
Google's Search documentation says it uses the mobile version of a site's content, crawled with the smartphone agent, for indexing and ranking. The same page advises that a mobile site should carry the same content as the desktop site. The design can differ, for example by using tabs or accordions, but the information should be equivalent, including headings, titles and descriptions.
The practical lesson for a cafe, accountant or clinic is simple. If your opening hours, service descriptions or prices appear on the desktop site but are trimmed from the phone version, you are showing less to visitors and less to Google.
How to check your own site
Google's PageSpeed Insights and the Core Web Vitals report in Search Console both draw on Google's Chrome User Experience Report data, so they are a sensible place to start. Paste your address into PageSpeed Insights and read the mobile result first. Treat the scores as a guide to what to look at, not a verdict.
Then do a human check. Take your own phone, switch off Wi-Fi, and try the tasks a customer would try:
- Open the home page and see how long it takes before you can read something useful.
- Find the phone number and tap it to call.
- Find your address and hours without zooming in.
- Open a service or product page and read it without side scrolling.
- Submit an enquiry or start a booking.
Write down every point of friction. A button that is too small to tap or a form that is awkward to complete is often more costly than a slightly slow banner.
Common causes of slow or awkward pages
These are widely recognised causes rather than rules specific to any platform. Large photographs uploaded straight from a camera without being resized or compressed. Autoplaying video at the top of the page. Many fonts, widgets or third party scripts loading at once. Images or banners with no reserved space, so the text jumps when they appear. Pop ups that cover the content on a small screen.
Questions to ask your provider
- How are images prepared before they go on the site?
- Can I see the mobile version of every page before launch?
- Who looks after the site once it is live, and how are speed and layout problems handled?
- Does the phone version show the same information as the desktop version?
