Most customers now find businesses on their phones, often on a mobile data connection. If your website takes too long to load, many visitors leave before they see your products or phone number. Speed also matters for search: Google uses page experience signals, including Core Web Vitals, as part of how it evaluates pages. This guide explains what to measure and what to fix, in plain language.
1. What Core Web Vitals measure
- Largest Contentful Paint (LCP): how quickly the main content, such as a hero image or headline, appears.
- Interaction to Next Paint (INP): how quickly the page responds when a visitor taps or clicks.
- Cumulative Layout Shift (CLS): how much the page jumps around while loading.
You can check these with free tools such as PageSpeed Insights and the Core Web Vitals report in Google Search Console.
2. The most common causes of slow sites
- Very large images uploaded straight from a camera or phone.
- Too many plugins, sliders, chat widgets and tracking scripts.
- Cheap or overloaded hosting.
- No caching or content delivery network (CDN).
- Heavy page builders and unused CSS and JavaScript.
3. Quick fixes with big impact
- Optimise images: resize to the size actually displayed and use modern formats such as WebP; lazy-load images below the fold.
- Enable caching: page and browser caching reduce server work for repeat visits.
- Use a CDN: serves files from locations closer to your visitors.
- Remove what you do not need: unused plugins, old tracking codes and heavy animations.
- Reserve space for images and ads to prevent layout shifts.
4. Deeper improvements
For larger sites, consider better hosting, a lighter theme, server-side rendering for web apps, code splitting and database optimisation. These need a developer, but the gains can be significant, especially for e-commerce and lead-generation sites.
5. Speed is part of a good website, not all of it
A fast site still needs clear content, easy navigation, a visible contact option and mobile-friendly design. Our business website development checklist covers the full picture, and our mobile app development guide explains when an app makes more sense than a website.
6. Keep monitoring
Check performance every month and after every major change, such as a new plugin or design update. Small additions add up over time. If you publish blogs, compress every image before uploading.
Many ATTPL group websites, such as ATTPL HOLDCO, follow the same practices: compressed WebP images, static pages and clean code.
Frequently asked questions
Does website speed affect Google ranking?
Page experience, including Core Web Vitals, is one of many signals Google considers. Content relevance matters more, but a slow site can lose visitors and conversions.
What is a good page load time?
Aim to meet the “good” thresholds for Core Web Vitals shown in PageSpeed Insights, on mobile as well as desktop.
Will changing hosting make my site faster?
Often, if your current hosting is overloaded. But images, plugins and code also matter, so test after each change.
