> People decide whether to wait for a page in a couple of seconds. Here is how to tell whether your site is slow, what usually causes it, and the handful of fixes that make the most difference.

Nobody waits for a slow website. They tap back and pick the next result, usually a competitor. You never see it happen, because a visitor who leaves before the page loads does not show up as an enquiry, a phone call or a complaint. They just quietly go elsewhere.

## How to tell if your site is slow

Start with the simplest test: open your homepage on your phone, on mobile data rather than Wi-Fi, and count. If you are past three seconds before you can see anything useful, it is too slow.

For a proper measurement, put your address into Google's free PageSpeed Insights tool. Look at the mobile result, not the desktop one, since that is how most of your visitors arrive. The number to watch is Largest Contentful Paint: how long the main content takes to appear. Under two and a half seconds is good.

## What usually slows a small business site down

**Images.** This is the cause most of the time. A photo straight off a phone or a camera can be several megabytes, shown on screen at a fraction of that size. Multiply that by a homepage full of pictures and the page is enormous.

**Too many plugins and add-ons.** Every chat widget, slider, pop-up and tracking script adds weight. Each one seemed like a good idea at the time.

**Cheap or overloaded hosting.** If the server takes a second to respond before anything else happens, nothing you do to the page itself will fully fix it.

**Video that plays on load.** A background video on the homepage looks impressive on a fast office connection and painful on a phone.

## The fixes that matter most

- **Resize and compress your images.** Modern formats like WebP are a fraction of the size of the original JPEG with no visible difference. This alone often halves the page weight.
- **Remove what you do not use.** Go through your plugins and scripts and ask of each one: when did this last earn its keep?
- **Load pictures as they are needed.** Images further down the page do not need to load until someone scrolls to them.
- **Check your hosting.** If your site is on the cheapest shared plan available, moving it can make a bigger difference than everything else on this list.

## Why it matters beyond patience

Speed is part of how Google decides which results to show, so a slow site is also a harder site to find. And it shapes how people feel about you before they have read anything: a site that drags feels like a business that does not quite have its act together, fair or not.
