Two websites with identical content can rank differently purely because one loads in 0.9 seconds and the other loads in 4. Speed is now a ranking factor that matters.
6 March 2026
Since Google switched to mobile-first indexing, the mobile version of your website is the one that counts. Not your desktop site. If your site looks great on a big screen but loads slowly or displays poorly on a phone, Google treats it as a slow, poorly structured site full stop. For local businesses in Australia, this matters more than you might think. Most of your potential customers are searching on their phone while standing in their kitchen, sitting in a car park, or waiting for a coffee. If your site takes too long to load on that phone, Google notices — and so does the person who just tapped your link.
Google measures three specific things about how your website feels to use, and they call them Core Web Vitals. First is Largest Contentful Paint (LCP) — how long it takes for the main content on the page to actually appear. If your hero image or headline takes four seconds to show up, that's a poor LCP score. Second is Interaction to Next Paint (INP) — how quickly the page responds when someone taps a button or clicks a link. If there's a noticeable lag between tapping and something happening, that's a problem. Third is Cumulative Layout Shift (CLS) — whether things jump around on the page while it loads. You've seen this before: you go to tap a button and suddenly the page shifts and you hit the wrong thing. Google measures all three of these and uses them as ranking signals.
The speed gap is a ranking gap
Two websites with identical content can rank differently purely because one loads in 0.9 seconds and the other loads in 4. Speed is now a ranking factor that matters. If your competitor's site is faster than yours and you're both targeting the same local keywords, they have an advantage you can't overcome with more blog posts or backlinks alone.
Drag-and-drop website builders like Wix and Squarespace make it easy to get a site online, but they come with trade-offs that directly affect speed. These platforms load large amounts of JavaScript that your site doesn't actually need — framework code, tracking scripts, animation libraries, and editor functionality that's baked into every page. You can't remove it. On top of that, your site shares server resources with thousands of other websites on the same infrastructure. When traffic spikes or servers are busy, your load time suffers. Most Wix and Squarespace sites score below 50 on Google PageSpeed Insights on mobile. That's not a minor issue — it's a measurable disadvantage in local search rankings.
The single most common reason small business websites load slowly is unoptimised images. A photo taken on a modern phone can be 4-8 MB. Upload that directly to your website and every visitor has to download that full file before they see anything. The fix is straightforward: convert images to WebP format (which is roughly 30% smaller than JPEG at the same quality), resize them to the actual dimensions they display at (not 4000 pixels wide for a 400-pixel thumbnail), and use lazy loading so images below the fold don't load until someone scrolls to them. These three changes alone can cut your page load time in half.
Server location matters more than you think
If your website is hosted on a server in the United States and your customers are in Brisbane, every single request has to travel across the Pacific Ocean and back. That adds 200-400 milliseconds of latency before your site even starts loading. For a local business targeting Australian customers, hosting on Australian servers or using a CDN with Australian edge nodes isn't optional — it's the difference between a site that feels instant and one that feels sluggish.
This isn't just about Google rankings. Site speed has a direct, measurable effect on whether visitors actually contact you. Research from Google shows that as page load time goes from 1 second to 3 seconds, the probability of a bounce increases by 32%. From 1 to 5 seconds, it increases by 90%. For a tradie or local service business getting 500 visitors a month, a slow site could be costing you dozens of enquiries without you ever knowing. The people who leave don't send you a message saying 'your site was too slow'. They just tap the back button and call your competitor instead.
PageSpeed Insights is a free tool from Google that analyses your website and gives you a score out of 100 for both mobile and desktop. The mobile score is the one that matters most. A score above 90 is excellent. Between 50 and 89 is where most sites sit — there are improvements to make but nothing catastrophic. Below 50 means your site is actively hurting your rankings and losing you visitors. The tool also gives you specific recommendations: which images are too large, which scripts are blocking the page from loading, and exactly how many seconds each issue costs you. It's not perfect, but it's the closest thing to seeing your site through Google's eyes.
You don't need to rebuild your entire site. Start with these changes in order of impact:
Run PageSpeed Insights on your site right now
Go to pagespeed.web.dev, paste your homepage URL, and check the mobile score. If it's below 50, speed is likely hurting your rankings today. Screenshot the results so you have a baseline.
Compress and convert your images to WebP
This is almost always the single biggest win. Use a free tool like Squoosh to convert your images to WebP format and resize them to the actual dimensions they display at. A hero image doesn't need to be wider than 1600 pixels.
Check where your site is hosted
Ask your hosting provider where your server is located. If it's in the US or Europe and your customers are in Australia, you're adding hundreds of milliseconds to every page load. Look for Australian hosting or a provider with local CDN nodes.
Remove scripts and plugins you don't actually use
Every analytics tool, chat widget, social media feed, and animation library adds weight to your page. If you installed a plugin six months ago and forgot about it, it's still slowing down every single page load for every single visitor.
Consider whether your platform is the bottleneck
If you've optimised everything you can and your mobile score is still below 60, the platform itself might be the problem. A custom-built site on a modern framework can score 95+ on mobile with the same content.
