Google stopped making Core Web Vitals a hard requirement in 2024. That doesn’t mean they stopped mattering-it means they matter differently now. If you’re building software, launching an AI product, or trying to own search traffic in Australia, understanding what’s actually changed will save you time and money.
The straightforward truth: Core Web Vitals affect ranking, but they’re no longer the primary lever. Relevance, content quality, and link authority are still king. That said, if your site performs poorly on these metrics, you’re leaving money on the table.
What Changed Since 2024
Google’s update in March 2024 downgraded Core Web Vitals from a hard ranking factor to a “nice to have” signal. That announcement spooked a lot of people. What actually happened: instead of Core Web Vitals being a knockout factor (missing them kills your ranking), they became a tiebreaker (when two pieces of content are equal quality, the faster one wins).
This is important. A slow site won’t outrank a fast site with identical content and authority. But a slow site will outrank a fast site if the slow site has better topical depth, more backlinks, or fresher data.
Practically, this means you should still optimise for these metrics, but you shouldn’t sacrifice content quality or distribution strategy to hit perfect Core Web Vitals scores.
The Three Vitals That Still Count
Core Web Vitals measure three real user experience metrics. Ignore them at your own cost.
- Largest Contentful Paint (LCP): How long until the biggest visible element loads. Target: under 2.5 seconds. This one still matters most because it directly impacts perceived speed. A fintech platform we worked with cut their LCP from 3.8s to 1.2s and saw a 15% improvement in conversion rate, independent of ranking changes.
- Interaction to Next Paint (INP): Replaced Cumulative Layout Shift as the third metric in 2024. It measures responsiveness-how long between a user’s action and the page responding. Target: under 200 milliseconds. For any product with forms, buttons, or real-time interaction, this is critical.
- Cumulative Layout Shift (CLS): Still tracked, but no longer part of the Core Web Vitals trio. However, Google still uses it as a ranking signal separately. Target: under 0.1. This is the “jank” factor-unexpected layout jumps that make your site feel broken.
The shift from CLS to INP was deliberate: Google moved from penalising visual instability to measuring actual interaction lag. This reflects real user frustration. If someone clicks your checkout button and the page takes 600ms to respond, they notice.
Why Performance Still Moves the Needle
Core Web Vitals affect ranking. More importantly, they affect conversion. If you’re running paid ads or relying on organic search, page speed directly impacts your return on ad spend and your organic traffic quality.
The relationship looks like this:
- Fast pages convert 3-5% higher on average than slow pages
- Each additional second of load time costs roughly 7% in conversion rate (though this varies by industry)
- Poor INP correlates with higher bounce rates on interactive pages
- Mobile users are more sensitive to slow pages than desktop users
If you’re building a SaaS product, an AI agent, or running an e-commerce store, you’re competing for attention. Someone else’s faster page is stealing your customers, whether Google ranks it higher or not.
For Australian startups competing against global players, performance becomes a product differentiator. A local fintech that loads in 1.2 seconds beats an international competitor that loads in 3.5 seconds, even if both rank on the first page.
Where Most Teams Slip Up
We see the same mistakes repeatedly. Here’s what to avoid:
Ignoring mobile performance: Google indexes mobile-first. If your mobile LCP is 3.8 seconds but your desktop is 1.2 seconds, you’re ranked by the mobile score. Most Australian businesses still don’t test on real 4G connections. Use Chrome DevTools with throttling or test on an actual mid-range Android phone.
Loading third-party scripts unnecessarily: Ad trackers, analytics, chatbots, and marketing pixels add up. Every external script is a potential blocker. Audit what you actually need. A lot of teams load 15+ trackers and only look at 3 of them.
Oversized images and video: This is less about engineering sophistication and more about discipline. Optimise before you upload. WebP format, responsive images with srcset, lazy loading for below-the-fold content. This alone solves most LCP problems.
Shipping unoptimised JavaScript bundles: If you’re using React, Vue, or similar frameworks without code-splitting and lazy loading, you’re penalising first-page load. Modern JavaScript frameworks are fast if you use them correctly, but defaults often aren’t.
Forgetting about INP during development: INP is measured in real user interactions. Test your forms, buttons, and interactive elements. Long-running JavaScript on the main thread kills INP. If you have heavy calculations (processing data, rendering charts), move them to Web Workers.
What to Actually Prioritise in 2026
If you’re building a new product or revamping your site, here’s the priority order:
- Content and relevance first. If you’re not solving a real problem for your audience, fast load times won’t save you.
- Core Web Vitals second. Aim for “good” (green on PageSpeed Insights), not perfect. Good is <2.5s LCP, <200ms INP, <0.1 CLS.
- Link building and authority third. This is still the strongest ranking signal. If you’re spending 100 hours optimising images and zero hours on outreach or content partnerships, you’re optimising the wrong thing.
- Regular monitoring fourth. Set up alerts. Use PageSpeed Insights, WebPageTest, or Real User Monitoring (RUM) tools. Performance degrades over time as you add features.

The Real Bottom Line
Core Web Vitals in 2026 are not a ranking guarantee. They’re a ranking tiebreaker and a conversion multiplier. If your site is slow, you’re losing money-whether through lower rankings or lower conversion rates. If your site is fast, you’re not guaranteed to rank first, but you’ve removed a major competitive disadvantage.
For Australian businesses, the advantage is straightforward: most competitors still aren’t optimising properly. A fast, well-built site with good content will outcompete slower alternatives. Don’t overthink it. Test on real devices, optimise images, lazy-load JavaScript, and ship it. Then measure, iterate, and ship again.
Speed isn’t a feature. It’s a baseline. Treat it that way.
