Why Is My Website Slow? How to Improve Website Speed

Few things lose visitors faster than a page that won’t load. On a phone with patchy signal, a few seconds of blank screen is enough for many people to go back and choose the next result. Speed matters to Google too, which measures how real visitors experience your pages.

The good news: most slow websites are slow for the same handful of reasons, and most of them can be fixed.

How to measure your website’s speed

• PageSpeed Insights. Enter a page’s address to see how real visitors experienced it over the previous 28 days, if your site has enough traffic, and a lab test with specific recommendations. Check the mobile results first.
• The Core Web Vitals report in Google Search Console, which groups your pages by real-world performance, so you can see which kinds of pages are slow.
• Your own phone, on mobile data. The test that matters most is what your customers experience.

Test your most important pages, not just the home page: service pages, location pages and the contact page.

What Core Web Vitals mean

Google’s Core Web Vitals measure three parts of the experience:

• Largest Contentful Paint (LCP): how quickly the main content appears. Good is 2.5 seconds or less.
• Interaction to Next Paint (INP): how quickly the page responds when someone taps or clicks. Good is 200 milliseconds or less.
• Cumulative Layout Shift (CLS): how much the page jumps around while it loads. Good is 0.1 or less.

They’re measured for real visitors, at the 75th percentile, so most of your visitors should have a good experience, not only those on fast connections.

Why websites get slow

• Huge images, uploaded straight from a camera or phone, many times larger than they need to be.
• Too many plugins and scripts. Sliders, chat widgets, tracking tags, social feeds and pop-ups can each add code to every page.
• Heavy page builders and themes that load far more code than the page uses.
• Slow or crowded hosting. Cheap shared hosting can be slow no matter how well the site is built.
• No caching, so the server rebuilds every page for every visitor instead of serving a ready copy.
• Video and fonts loaded in ways that hold up the page.
• Third-party embeds: maps, review widgets, booking tools and video players.

The fixes that make the biggest difference

1. Resize and compress images, and serve modern formats like WebP or AVIF. Load images further down the page only when they’re needed, but never delay the main image at the top.
2. Remove what you don’t need. Uninstall unused plugins, drop the slider, and question every script: does it earn its place?
3. Use caching on the server and, ideally, a content delivery network (CDN) that serves your pages from locations near your visitors.
4. Choose good hosting. Managed hosting built for your platform is often the single biggest improvement.
5. Load third-party tools carefully. Embed maps and videos so they load when tapped, not with the page.
6. Limit fonts to the families and weights you actually use, and serve them efficiently.
7. Keep the platform updated, since new versions often bring performance improvements.

How to speed up a WordPress site

WordPress runs a large share of business websites, and the same fixes apply, with a few specifics:

• Use a lightweight theme or builder, and avoid stacking several page builders.
• Choose hosting with server-level caching, or use a reputable caching plugin.
• Use an image optimization plugin, or optimize images before uploading them.
• Review your plugins every few months; remove anything unused and replace heavy plugins with lighter ones.
• Keep PHP and WordPress itself on current versions.

Speed and your business

A faster site doesn’t just score better. Visitors see your services sooner, look at more pages and are more likely to get in touch. On a phone, when someone needs help quickly, speed is part of your customer service.

Keeping it fast

Speed isn’t fixed once. New photos, plugins and tracking tags slow a site down over time. Check your main pages every few months, and before adding any new tool, ask what it will cost in speed. Our article on website maintenance covers the routine that keeps a site in shape.
