A slow website costs you visitors, leads and sales. Most people leave a page that takes too long to load, and Google also uses page experience when it ranks sites. The good news is that a website speed test is free, quick and tells you exactly what to fix.
Why Website Speed Matters
- Conversions: Slow pages lose customers before they see your offer.
- SEO: Speed and Core Web Vitals are part of Google’s page experience signals.
- Mobile users: Many visitors are on phones with weaker connections.
- Ad performance: Slow landing pages waste your ad budget.
How to Run a Website Speed Test
- Open a speed testing tool.
- Enter your page URL (test your homepage and also key pages like product or service pages).
- Run the test on mobile and desktop.
- Note the scores and the list of recommendations.
- Test again after each fix to confirm the improvement.

Understanding Your Results: Core Web Vitals
Google focuses on three main measurements:
| Metric | What it measures | Good target |
|---|---|---|
| LCP (Largest Contentful Paint) | How fast the main content appears | 2.5 seconds or less |
| INP (Interaction to Next Paint) | How quickly the page responds to clicks and taps | 200 ms or less |
| CLS (Cumulative Layout Shift) | How much the layout jumps while loading | 0.1 or less |
If your results are outside these targets, you have clear places to improve.
Common Reasons for a Slow Website
- Large, uncompressed images
- Cheap or overloaded hosting
- Too many plugins, apps or scripts
- No caching or CDN
- Heavy themes and page builders
- Render-blocking CSS and JavaScript
- Unoptimised fonts and third-party widgets
How to Improve Your Speed Test Results
Optimise images. Compress them and use modern formats like WebP. Add lazy loading for images below the fold.
Use caching and a CDN. Caching stores ready-made pages, and a CDN serves them from a location close to the visitor.
Reduce code and plugins. Remove what you do not use. Minify CSS and JavaScript and delay non-essential scripts.
Upgrade hosting. Good hosting improves server response time, which affects every other metric.
Fix layout shifts. Set width and height on images and ad spaces so the page does not jump.
Keep your site maintained. Updates, database cleanup and regular testing stop speed from slowly getting worse.
Speed Fixes by Platform
Different platforms need different fixes:
- WordPress: caching, plugin cleanup, image compression and a lightweight theme. See our WordPress Development service.
- WooCommerce: database optimisation, fast hosting and lean product pages. See WooCommerce Development.
- Shopify: theme code, app overload and image sizes. See Shopify Store Development.
- Online stores in general: category and product page speed directly affects sales. See E-Commerce Development.
- Wix: image handling and unneeded apps. See Wix Website Development.
- Company sites and platforms: see Business Website Development, SaaS Website Development and LMS Website Development.
Speed problems also connect with search visibility. If your tests show crawling or performance issues, our Technical SEO service can help. To measure the effect of your improvements on traffic and leads, use our Analytics & Reporting service.
Keep Your Site Fast Over Time
Speed is not a one-time job. New plugins, large images and extra scripts slow a site down again. Our Website Maintenance & Support service includes regular updates, monitoring and performance checks, so your site stays fast.
When to Get Professional Help
Consider an expert if:
- Your mobile score stays low after basic fixes
- Your theme or code is the real problem
- You run an online store and every second affects sales
- You are planning a redesign and want speed built in from the start

Frequently Asked Questions
What is a good website speed test score?
Aim for good Core Web Vitals (LCP under 2.5 seconds, INP under 200 ms and CLS under 0.1) rather than chasing a perfect 100.
How often should I test my website speed?
Test monthly, and also after major changes such as a new theme, plugin or design update.
Why is my mobile score lower than desktop?
Phones have less processing power and slower connections, so the same page is harder to load.
Do speed test scores affect SEO?
Page experience and Core Web Vitals are part of Google’s signals, though content relevance still matters most.
Can I fix a slow website without a developer?
Basic fixes like image compression and caching plugins are easy. Code and server problems usually need professional help.
