Website speed is no longer a technical detail. If a page loads slowly, people leave, Google evaluates the site more poorly and your ads become more expensive because of a weaker user experience.
Core Web Vitals are the metrics Google uses to measure real-world speed and stability.
What LCP, INP and CLS mean
LCP shows how quickly the main content appears. INP reflects how fast the site responds to user actions. CLS measures whether elements shift while the page loads.
If these metrics are weak, users experience the site as sluggish — even when the design looks modern.
The most common causes of a slow website
Heavy unoptimised images, too many plugins, inefficient fonts, render-blocking JavaScript and weak hosting. On WordPress and WooCommerce the problem is often plugin sprawl.
On custom projects the issue is usually missing caching, slow database queries or oversized media files.
What to optimise first
Start with images: modern formats like WebP, correct dimensions and lazy loading. Then remove unnecessary scripts and check the mobile version — most traffic is already on phones.
Caching, a CDN and clean code often outperform a full redesign.
The link to SEO and sales
A faster website improves behavioural signals: lower bounce rate, more pages viewed and more completed enquiries. That helps both organic traffic and paid campaigns.
If you spend on Google Ads while the site takes 5–6 seconds to load, part of the budget is simply wasted.
When to get technical help
If PageSpeed and real-user data are weak and your team does not know where to start, you need a technical audit with priorities. Not every automated recommendation matters equally.
