Most business owners judge a website by how it looks. Visitors judge it by how it feels: how quickly something appears, whether the page jumps around while it loads, and whether a tap does something straight away. Google measures those three things as Core Web Vitals, and the 2025 Web Almanac, published by HTTP Archive in January 2026, shows how many websites worldwide actually get them right.
What Core Web Vitals Measure
There are three measurements, each with a "good" threshold set by Google's web.dev guidance. It recommends measuring at the 75th percentile of page loads, across mobile and desktop.
| Metric | What it measures | Good result |
|---|---|---|
| Largest Contentful Paint (LCP) | How fast the main content loads | Within 2.5 seconds |
| Interaction to Next Paint (INP) | How quickly the page responds to taps and clicks | 200 milliseconds or less |
| Cumulative Layout Shift (CLS) | How much the layout jumps while loading | 0.1 or less |
Fewer Than Half of Mobile Sites Pass
According to the Web Almanac's Performance chapter, 48% of mobile websites passed all three Core Web Vitals in 2025, up from 44% in 2024. On desktop the figure was 56%, up from 55%. Put the other way around, more than half of mobile websites still fail at least one of the three.
Loading Speed Is the Hardest Part
On mobile, 62% of websites had a good Largest Contentful Paint, compared with 81% for layout stability and 77% for responsiveness, which was up from 74% in 2024. In other words, getting the main content on screen quickly is where most sites lose points, while jumping layouts and slow taps are less common problems.
What This Means If You Run a Local Business in South West WA
The Almanac describes the web as a whole, not businesses in Busselton, Dunsborough or Margaret River, so treat it as a benchmark rather than a verdict on your own site. The useful takeaway is that a fast, stable mobile website is still not the default, which means it can set you apart from competitors who have not looked at theirs in years.
A practical first step is to run your address through Google's PageSpeed Insights, check the mobile results first and start with the item it flags as the biggest issue. If your website was built a few years ago and never revisited, that check is worth doing this week.
