Why is my website slow?
Suggestions appear as you type. Use the up and down arrows to choose one, or press Enter to ask.
Most slow small-business sites come down to oversized photos and video, no caching, too many plugins or scripts, or a crowded server. Test your main pages in Google's PageSpeed Insights on mobile to see which applies. Then fix the biggest problem first. That's usually the images at the top of the page.
How do I test my site’s speed?
- Pick the pages that matter: home, your main service page and your contact page.
- Open PageSpeed Insights, paste in the page address, and select Analyze.
- Read the mobile results first. Google’s PageSpeed Insights guide says the mobile test simulates a mid-range phone on a mobile network.
- Check the top section, if there is one. That’s real-world data from Chrome users over the past 28 days. Small sites often don’t have enough visits to show it.
- Scroll to the suggestions. They name the exact images, scripts and files slowing the page.
- Write down the main numbers so you can compare after each fix.
Our free speed test gives a plain-English summary too.
Expected result: you know which page is slow and what’s making it slow.
The short version
- Measure first with PageSpeed Insights on mobile.
- The usual cause is oversized photos and video. Fix the biggest item first, then test again.
What do the three main numbers mean?
Google measures loading with three Core Web Vitals. These targets come from web.dev’s guide to Web Vitals:
| Measure | What it checks | Good |
|---|---|---|
| Largest Contentful Paint (LCP) | How fast the main content, often a big photo, appears | 2.5 seconds or less |
| Interaction to Next Paint (INP) | How fast the page responds to a tap or click | 200 milliseconds or less |
| Cumulative Layout Shift (CLS) | How much the page jumps around while loading | 0.1 or less |
Don’t chase a perfect score. A page that feels quick and passes these three is in good shape. See what your PageSpeed score means.
What usually makes a site slow, and what fixes it?
Huge photos and video. A photo straight from a phone can be many times bigger than the page needs, and a background video can outweigh everything else. Web.dev’s guide to improving LCP recommends images sized to fit, compressed, and saved in modern formats such as WebP or AVIF. Fix the image at the top of each page first. See change a photo or banner and the right image sizes.
No caching or CDN. Without caching, the server builds every page from scratch for every visitor. A cache keeps a ready-made copy, and a content delivery network serves files from a location near the visitor. See caching and CDN.
Too many plugins and scripts. WordPress’s optimization guide names unneeded plugins as a common cause. Chat widgets, booking tools, social feeds and tracking tags each add weight too. Keep what you use. See how many plugins is too many.
Slow or crowded hosting. Very cheap shared hosting can be slow whatever you do to the site. If the first part of the page takes a long time to arrive, the server is the likely cause. An old PHP version on the server matters too.
Why does it matter?
People leave slow pages before they read a word, especially on phones. Google also says its ranking systems reward a good page experience, though relevant, helpful content matters more. See Core Web Vitals.
What are the common mistakes and edge cases?
- Testing only on your office computer. Fast Wi-Fi and a fast machine hide problems. Test a phone on mobile data.
- Changing many things at once. You won’t know what helped, or what broke.
- Slow only in the admin area. That’s usually a plugin or the server, not your images.
- Slow on one page. Look for a big gallery, a video, a map or an embedded feed there.
- Suddenly slow. Think about what changed: a new plugin, a big upload, a new marketing tag.
- Moving hosts doesn’t mean moving your domain. Your domain can stay where it’s registered while the website moves. See can you move my website to your hosting?
What if this didn’t work?
- Scores look fine but it still feels slow: test on a phone, on mobile data, in a private window.
- Fixes didn’t move the numbers: ask your host how long the server takes to respond and which PHP version you’re on.
- So slow it times out: treat it as an outage. See why is my website down.
How long does it take, and what does it cost?
How long the work takes depends on how many images need compressing and what the site is built on. Caching and hosting changes take longer, and cost depends on what the site needs. Ask for a quote before work starts.
How does E-3 handle this?
E-3 runs a speed program for sites that need real work. A sensible order of work: compress and resize images and video, convert images to modern formats, turn on caching that suits the site, add a CDN where it helps, and, if the host is the bottleneck, move the site to better hosting, such as our managed hosting.
