My site is slow
Why your website may be loading slowly and the most effective steps to diagnose and improve its speed.
- Difficulty
- Beginner
A slow website frustrates visitors, and it can work against you in search too. If pages are taking more than a few seconds to load, something needs attention. This guide walks you through how to diagnose the problem and what we can do to fix it.
Quick summary
Test your speed with a free tool, then rule out your own internet connection. Slow sites are usually caused by large unoptimized images, too many plugins, or a hosting plan that isn't keeping up with traffic. Share your speed test results with us and we'll identify the biggest wins.
Step 1 — Rule out your own connection
Before assuming the site is slow, check that the issue isn't on your end.
Ask someone else to load the site. A colleague on a different network, or someone in a different city.
Try loading a well-known fast website (like google.com). If that's also slow, your internet connection is the issue, not the site.
Restart your router if your internet seems slow in general.
Step 2 — Measure the speed with a free tool
You need data, not guesswork. These tools give you an objective speed score.
Go to pagespeed.web.dev — Google's free PageSpeed Insights tool.
Enter your site URL and click Analyze.
Note the scores for both Mobile and Desktop. Google's own bands: 90 or above is good, 50 to 89 needs improvement, and below 50 is poor.
Take a screenshot of the results and send it to us. This tells us exactly where the bottlenecks are.
Scores look lower than expected?
Google tests mobile on a simulated mid-range phone over a mobile network, and desktop on an emulated desktop with a wired connection, so the mobile score is usually the lower of the two. What matters is the trend over time and the specific issues flagged.
Common causes of slow sites
Understanding what's slowing your site helps you have a productive conversation with us.
| Cause | Explanation |
|---|---|
| Large images | Photos not resized or compressed for the web. Often the biggest single factor. |
| Too many plugins | Every active plugin adds code that slows page loading. |
| No caching | Without caching, every visitor loads the site from scratch. |
| Slow hosting | Budget or shared hosting can't handle traffic spikes. |
| No CDN | Without a CDN, visitors far from the server get slow loads. |
| External scripts | Trackers, chat widgets, and ad scripts add loading time. |
| Unoptimized theme | Some themes are built with far more code than necessary. |
Step 3 — Check for obvious image problems
Images are one of the most common causes of slow sites — and also among the easiest to fix.
Start with the PageSpeed Insights report from Step 2. Its list of audits names the individual files holding the page back, images included.
To weigh one image yourself, right-click it on your page, save it to your computer, and look at the file size in Finder (Mac) or File Explorer (Windows). A browser tab won't show you the size.
Compare it with our rule of thumb. Most photos on a web page should be under 200 KB. Anything over 1 MB is almost certainly slowing your site.
Don't replace images yourself
If you're not sure how to compress and re-upload images correctly, contact us. Replacing images incorrectly can remove them from other pages.
Step 4 — Check for recent changes
Did you recently:
- Add a new section or widget to a page?
- Install a new plugin?
- Embed a video or map?
- Change your theme?
Any of these can add loading time. Note what changed and when, and include it when you contact us.
What to send us
- Your site URL
- A screenshot of your PageSpeed score (see Step 2)
- Which pages feel slowest
- Any recent changes that coincide with the slowdown
- Your hosting provider (if you know it)
Common questions
My site was fast before but slowed down recently.
Something changed. It could be a new plugin, a large image upload, a theme update, or a traffic spike. Check what was added or changed around the time the slowdown started. Share that timeline with us.
The speed test gives a low score but the site feels fine to me.
Speed test scores measure technical load factors, not just what you perceive. A site that feels fine to you on a fast connection may be very slow for visitors on mobile or rural broadband. Improving the score benefits all users.
Will improving my speed help my Google ranking?
It can help, but it isn't a lever you pull for rankings. Google says there is no single "page experience signal", and that its core ranking systems do use Core Web Vitals — its measures of loading speed, responsiveness and visual stability. Google's own framing is that a great page experience "can contribute to success in Search" on the many queries where plenty of helpful content is competing; relevant content still comes first. Faster pages also hold visitors better, whatever search does. See site speed & SEO for more detail.
How long does a speed optimization take?
Basic optimizations (image compression, caching setup, plugin audit) can often be done in a few hours. More significant improvements — hosting upgrade, theme work, code optimization — take longer and are quoted separately.
