In the world of Australian business, first impressions are everything. If a customer walks into your shop in Fortitude Valley and the door sticks, or the lights flicker, they’re likely to walk straight back out. Your website is no different. Google’s Core Web Vitals are essentially a digital 'building inspection'—they measure how fast, stable, and responsive your site feels to real people.
Since 2021, Google has used these metrics as a ranking factor. This means if your site is sluggish, you aren't just annoying your visitors; you’re likely sliding down the search results behind your faster competitors. This guide will walk you through how to measure and fix these issues without needing a PhD in computer science.
Prerequisites: What You’ll Need
Before we dive into the technical bits, make sure you have the following ready:- Google Search Console access: This is the best way to see how Google views your site.
- Admin access to your website: (e.g., your WordPress login or Shopify dashboard).
- A bit of patience: Optimising for speed can be a bit like untangling a messy fishing line—it takes a delicate touch.

Step 1: Understand the "Big Three" Metrics
Before we start clicking buttons, you need to know what we’re actually trying to fix. Google focuses on three specific metrics. Think of them as the 'Vital Signs' for your site's health.
- LCP (Largest Contentful Paint): This measures loading performance. Specifically, how long it takes for the biggest thing on your page (usually a hero image or a heading) to show up.
- FID (First Input Delay) / INP (Interaction to Next Paint): This measures responsiveness. When a user clicks a button, how long does it take for the site to actually do something?
- CLS (Cumulative Layout Shift): This measures visual stability. Have you ever tried to click a link, but right as you tap, the page jumps and you click an ad instead? That’s a bad CLS score.
Pro Tip: Google is currently transitioning from FID to INP. Don't let the acronyms scare you; they both essentially mean "make sure the site reacts quickly when people touch things."
Step 2: Run Your First Audit
You can't fix what you haven't measured. We’re going to use Google’s free tool, PageSpeed Insights.
- Go to PageSpeed Insights.
- Enter your URL (start with your homepage, as it's usually the most important).
- Click 'Analyse'.
Step 3: Tackle the "Heavy" Images (Fixing LCP)
In 90% of the audits we do at Local Marketing Group, the biggest culprit for a slow LCP is a massive, unoptimised image. Someone takes a beautiful photo on their iPhone, uploads it directly to their site, and suddenly there's a 5MB file trying to squeeze through a mobile 4G connection.
- Resize before you upload: If your website content area is only 800 pixels wide, don't upload a 4000-pixel wide image. Use a free tool like Canva or Squoosh.app to resize it.
- Use Modern Formats: Swap JPEGs for WebP. WebP files are significantly smaller but keep the same quality.
- Implement Lazy Loading: This tells the browser: "Don't bother loading the images at the bottom of the page until the user actually scrolls down there."
Step 4: Fix the "Jumpy" Content (Fixing CLS)
This is where the interface gets a bit fiddly, but it’s crucial for user experience. CLS usually happens because the browser doesn't know how much space to reserve for an image or an ad before it loads.
- Set Dimensions: Always ensure your images have width and height attributes in the code.
- Reserve Space for Ads/Embeds: If you have an Instagram feed or a Google Map embedded, wrap it in a 'div' (a container) with a fixed height so the page doesn't "pop" open when the map finally loads.
- Avoid Inserting Content Above Existing Content: Don't have a newsletter pop-up or a cookie banner that suddenly appears at the top of the page and pushes everything down. It drives users (and Google) crazy.
Step 5: Clean Up Your Code (Fixing INP/FID)
This step is a bit more technical, but it makes a massive difference. When a browser loads your site, it has to read through all your code (HTML, CSS, and JavaScript). If you have too much "junk" code, the browser gets 'analysis paralysis' and stops responding to user clicks.
- Minify your CSS and JS: This just means removing all the extra spaces and comments in the code to make the file smaller.
- Remove Unused Plugins: If you're on WordPress and have 40 plugins active, your site will be slow. If you aren't using a plugin, delete it. Don't just deactivate it—get rid of it.
- Delay Non-Essential JavaScript: Do you really need your Facebook Chat widget to load the very millisecond someone lands on the page? Probably not. Delaying these scripts until the main content has loaded will skyrocket your responsiveness scores.
Step 6: Choose Quality Australian Hosting
I cannot stress this enough: if your business is in Brisbane but your website is hosted on a cheap server in Ohio, USA, your site will be slow. Data has to travel through physical cables under the ocean.
- The Latency Factor: Every time a user clicks, a signal has to go to the server and back. Choosing a host with servers in Sydney, Melbourne, or Brisbane can shave half a second off your load time instantly.
- Server Response Time (TTFB): If your PageSpeed report says "Reduce initial server response time", your host is likely the bottleneck.
Step 7: Leverage a Content Delivery Network (CDN)
A CDN like Cloudflare acts like a series of mini-warehouses for your website across the globe. When someone in Chermside visits your site, Cloudflare serves them a saved copy from their nearest Australian data centre.
- Step-by-step: Sign up for a free Cloudflare account, point your domain's nameservers to them, and toggle on the 'Rocket Loader' and 'Auto Minify' settings. It’s one of the easiest 'wins' for speed.
Step 8: Monitor via Google Search Console
Once you've made these changes, don't just walk away.
- Log into Google Search Console.
- On the left-hand menu, click 'Core Web Vitals'.
- You'll see two charts: Mobile and Desktop.
- Once you’ve fixed issues, click into the report and hit 'Validate Fix'. This tells Google to re-crawl your site and confirm you've done the work.

Common Mistakes to Avoid
- Over-optimising for Desktop: We see this all the time. A business owner checks their site on their high-speed office iMac and thinks it's fast. Most of your customers are on a patchy 4G connection at a bus stop. Always optimise for mobile first.
- Using too many Google Fonts: Each font weight (Bold, Light, Italic) is a separate file the browser has to download. Stick to two fonts max.
- Ignoring Video Files: Never upload a raw video file (MP4) directly to your website. Host it on YouTube or Vimeo and embed it. Your server will thank you.
Troubleshooting
"I fixed the images, but my score didn't move!" Check if you have a caching plugin active. You might be looking at an old version of your site. Clear your site cache and your browser cache, then run the test again. Also, check if your 'Hero' image is being lazy-loaded. You should actually exclude the very first image people see from lazy-loading so it appears instantly. "PageSpeed Insights says my 'Total Blocking Time' is high." This is almost always too much JavaScript. If you're using a heavy page builder like Elementor or Divi, this is a common struggle. Try using an optimisation plugin like 'WP Rocket' (it’s paid, but worth every cent for the time it saves).Next Steps
