BeforeHero images, product images, and background images uploaded at camera resolution add 2MB to 8MB per page load without compression. On Australian mobile connections, this is the primary driver of slow Largest Contentful Paint. Converting images to WebP or AVIF and serving them at display-appropriate dimensions reduces image payload by 70 to 85 percent, which is the single most impactful fix on most Australian business sites.
AfterGoogle uses Core Web Vitals as a ranking signal. Pages that fail LCP, CLS, or INP are at a ranking disadvantage compared to pages that pass, particularly in competitive local searches in Sydney, Melbourne, and Brisbane. Fixing Core Web Vitals removes a confirmed negative factor and brings technical performance to the standard Google rewards.
BeforeJavaScript loaded in the document head stops the browser from rendering visible page content until each script is downloaded and executed. This is common on WordPress sites with multiple plugins and Shopify stores with third-party app scripts. The browser shows a blank screen while it waits. Deferring or asynchronously loading non-critical scripts removes this bottleneck and reduces the time before a visitor sees anything on the page.
AfterAustralian mobile users are no more patient than users anywhere else. A page that takes more than 3 seconds to load loses a measurable percentage of its visitors before they see any content. Reducing LCP to under 2.5 seconds retains those visitors and gives your content a chance to do its job.
BeforeAustralian business sites frequently carry scripts from Google Analytics, Google Ads conversion tracking, Facebook Pixel, LinkedIn Insight Tag, live chat widgets, heatmap tools, review platform badges, and legacy scripts from past campaigns. Each script adds a network request to an external server. Many are duplicated in both the page template and Google Tag Manager. Auditing and removing unused or redundant scripts reduces page weight and removes latency from external server connections.
AfterFaster landing pages produce higher Quality Scores in Google Ads, which reduces cost-per-click and improves ad placement. For Australian service businesses spending $3,000 to $30,000 per month on paid search, the conversion rate improvement from landing page speed optimisation is typically measurable within one billing cycle.
BeforeCumulative Layout Shift registers every time visible content moves as the page loads. On Australian e-commerce and trade websites, the most common causes are images with no explicit dimensions, Google Ads or programmatic ad containers that resize after content loads, and web fonts that swap in and shift text blocks. Google records each shift and uses CLS as a ranking signal. A CLS score above 0.1 is a ranking disadvantage.
AfterA fast score on an FTTP connection does not mean your site is fast for a visitor on FTTN or mobile in outer suburbs. After optimisation, your site passes Core Web Vitals in field data for real Australian users across connection types, not just in controlled lab tests.
