Core Web Vitals Optimisation Gauteng | Pass Google's Performance Tests and Rank Higher
Google officially uses Core Web Vitals as a ranking factor. If your site fails these speed and usability tests, you're being pushed down in search results in favour of faster competitors.
What Are Core Web Vitals and Why Does Google Care?
Core Web Vitals are three specific measurements that Google uses to assess whether your website gives visitors a good experience. They are: LCP (how long it takes for the main content to appear on screen), INP (how quickly your site responds when a visitor clicks or taps), and CLS (how much the page layout shifts around while it's loading). Google introduced these as official ranking factors because a slow, jumpy website frustrates users and reflects badly on Google's search results.
Here's the business impact: if two websites have identical content and backlinks but yours fails Core Web Vitals and theirs passes, Google will rank the faster site above yours. For competitive keywords where every advantage matters, failing these tests costs you real rankings and real revenue. The good news is that most Core Web Vitals issues can be fixed with targeted technical improvements.
We identify exactly which of your pages are failing Core Web Vitals, why they're failing, and fix every issue to ensure your site passes Google's performance requirements on both mobile and desktop.
\n⚠ Signs You Have This Problem- ✗Your website loads slowly on mobile, especially over 3G or 4G connections
- ✗Visitors complain that your site feels sluggish or that buttons don't respond immediately
- ✗Images and text jump around as your page loads, which is frustrating for visitors
- ✗Google Search Console shows red or orange Core Web Vitals scores
- ✗Your PageSpeed Insights score is below 50 on mobile
- ✗You have a WordPress site with many plugins and a heavy theme
Test Your Core Web Vitals in 60 Seconds
Google provides free tools to test your Core Web Vitals. This is exactly what Google sees when it assesses your site's performance.
\nRun these two free tests right now:
1Open Google PageSpeed Insights (pagespeed.web.dev, free). Type in your website address and click Analyse. Look at the scores for both Mobile and Desktop. A score of 90 or above is good. Below 50 is poor and will be affecting your rankings.2Focus on the three Core Web Vitals metrics: LCP (should be under 2.5 seconds), INP (should be under 200ms), and CLS (should be under 0.1). The tool colour codes them green (pass), orange (needs improvement), or red (fail).3Open Google Search Console and click "Experience" then "Core Web Vitals." This shows real-world data from your actual visitors, not just a lab test. It shows how many URLs are passing, failing, or needing improvement across your whole site.4Test your homepage specifically on mobile at 3G speed. This is how Google measures mobile performance. In PageSpeed Insights, the mobile score is always lower than desktop and is the more important one for rankings.How We Fix Core Web Vitals
