Website Speed Optimization: How to Load in Under 2 Seconds

A slow website quietly loses customers. People on mobile data won’t wait for heavy pages, and Google uses page experience signals when ranking results. The good news: most slow sites can be made dramatically faster with a handful of fixes.

How to measure speed properly

Use these free tools:

• PageSpeed Insights — shows lab tests and real-user data (when available) for mobile and desktop.
• Search Console → Core Web Vitals — shows which groups of pages pass or fail for real visitors.

Focus on the three Core Web Vitals:

• LCP (Largest Contentful Paint): how quickly the main content appears. Aim for under 2.5 seconds.
• INP (Interaction to Next Paint): how quickly the page responds when someone taps or clicks. Aim for under 200 ms.
• CLS (Cumulative Layout Shift): how much the page jumps around while loading. Aim for under 0.1.

Always test the mobile version — that is what most of your visitors use.

The fixes that matter most

1. Optimise images

Images are usually the biggest problem.

• Resize images to the size they are actually displayed.
• Use modern formats like WebP or AVIF.
• Lazy-load images below the fold.
• Give images fixed dimensions to prevent layout shift.

2. Cut unnecessary code

• Remove plugins, sliders, chat widgets and tracking scripts you don’t really need.
• Load third-party scripts after the main content, not before.
• Avoid heavy page builders for simple pages where possible.

3. Use caching and a CDN

• Page caching serves ready-made pages instead of rebuilding them on every visit.
• A CDN such as Cloudflare serves files from servers closer to your visitors.

4. Choose the right hosting

Very cheap shared hosting can be slow under load. For business-critical sites, decent hosting with enough resources, a recent PHP version and server-level caching pays for itself.

5. Load fonts efficiently

• Use one or two font families, in only the weights you need.
• Self-host fonts or preload them, and use font-display: swap.

6. Keep the database tidy (for WordPress)

Old revisions, spam comments and leftover plugin tables slow down dynamic sites. Clean them regularly and use object caching where available.

Quick wins checklist

• Compress and resize the hero image
• Remove unused plugins and scripts
• Turn on page caching
• Enable a CDN
• Lazy-load images and embedded videos
• Set image width and height attributes
• Update PHP/WordPress/plugins to current versions

Speed is a habit, not a one-time task

New images, plugins and scripts creep in over time. Re-test after every major change and review speed every few months.
