Core Web Vitals became a Google ranking signal in 2021. Since then, pages that pass all three metrics on mobile have a measurable advantage over pages that fail, particularly in competitive categories where technical quality separates sites of similar authority. For Australian businesses, failing Core Web Vitals means two problems simultaneously: lower organic rankings and worse conversion rates from the visitors who do arrive.
TPR Media diagnoses and fixes Core Web Vitals failures as part of our Load Speed Optimisation service. We validate in Google Search Console after every fix.
LCP measures how long it takes for the largest visible content element to load. This is usually the hero image, the main heading or the first large block of text. Google considers anything under 2.5 seconds as good. Between 2.5 and 4 seconds needs improvement. Over 4 seconds is poor.
For a WordPress site, the LCP element is almost always the hero image. Run PageSpeed Insights and click on the LCP screenshot to see exactly which element Google is measuring.
INP replaced First Input Delay (FID) in March 2024. It measures the responsiveness of a page across the entire visit, not just the first interaction. Every click, tap and keyboard input is measured. Google considers anything under 200ms as good. Between 200 and 500ms needs improvement. Over 500ms is poor.
INP failures are harder to diagnose than LCP. Use Chrome DevTools Performance tab to identify long tasks on the main thread. Each red block represents a period where the browser cannot respond to user input.
CLS measures how much the visible content of a page shifts during loading. A high CLS score means the page is jumping around as it loads, which leads to mis-clicks and a frustrating experience. Google considers anything under 0.1 as good. Between 0.1 and 0.25 needs improvement. Over 0.25 is poor.
Most sites pass Core Web Vitals on desktop but fail on mobile. Mobile has slower CPUs, slower network connections and smaller screens that demand different image sizes. Google's ranking algorithm uses mobile scores, not desktop scores. A green desktop score means nothing if mobile is red.
| Metric | Good (mobile) | Needs improvement | Poor |
|---|---|---|---|
| LCP | Under 2.5s | 2.5 to 4.0s | Over 4.0s |
| INP | Under 200ms | 200 to 500ms | Over 500ms |
| CLS | Under 0.1 | 0.1 to 0.25 | Over 0.25 |
A professional load speed audit and fix project starts from $900 at TPR Media. The scope depends on platform complexity, hosting environment and the number of issues found. WordPress stores with many plugins typically need more work than a clean Shopify build.
Most one-off speed projects are complete within five to ten business days. Emergency fixes for critical Core Web Vitals failures can turn around faster. Ongoing tuning retainers run month to month.
Yes. Google uses Core Web Vitals as a ranking signal. Improving Largest Contentful Paint, Cumulative Layout Shift and Interaction to Next Paint can lift your position, especially in competitive categories where technical quality separates similar-authority sites.
Yes. TPR Media audits and fixes WordPress, Shopify and Magento sites regardless of who built them. We start with a full Lighthouse and Web Vitals audit before touching anything.
TPR Media operates from Level 34, 1 Eagle Street, Brisbane City QLD 4000, serving clients across Brisbane and Australia-wide.
Core Web Vitals are Google's three real-world performance metrics: Largest Contentful Paint (LCP, good under 2.5s), Interaction to Next Paint (INP, good under 200ms) and Cumulative Layout Shift (CLS, good under 0.1). Google uses mobile scores for ranking. LCP failures typically stem from unoptimised hero images or slow hosting. INP failures come from heavy JavaScript. CLS failures come from images without dimensions and late-loading fonts. TPR Media fixes all three on WordPress, Shopify and Magento sites.
