You only get a few seconds. If your website is still loading when a customer's patience runs out, they hit back and tap the next result, often your competitor. Speed isn't a technical detail. It's part of your sales process.
Why speed matters
- Visitors leave slow sites. Especially on phones, where signals can be weak.
- Google pays attention to it. Google measures how quickly pages load and respond, as part of what it calls "Core Web Vitals," and uses page experience as one of many signals.
- Slow feels unprofessional. A sluggish site makes the business behind it seem sluggish too.
- Ads cost more when pages disappoint. If you run Google Ads, a poor landing page experience can hurt your results.
How to test your site
- Go to PageSpeed Insights (pagespeed.web.dev).
- Enter your website address.
- Look at the mobile results first, since that's how most customers see you.
You'll see a score and a list of suggestions. Don't panic about a perfect 100. Focus on the specific problems it lists.
Google's Core Web Vitals include:
- Largest Contentful Paint (LCP): how long until the main content shows. Google considers 2.5 seconds or less good.
- Interaction to Next Paint (INP): how quickly the page responds when someone taps or clicks. 200 milliseconds or less is good.
- Cumulative Layout Shift (CLS): how much things jump around while loading. 0.1 or less is good.
The most common causes on small business sites
1. Huge photos
This is the number one problem. A photo straight off a modern phone can be several megabytes. Your website rarely needs it that big.
Fix: Resize photos to the size they actually display (often 1,600 pixels wide or less) and compress them. Modern formats like WebP are much smaller than old JPEGs.
2. Auto-playing videos and sliders
Big background videos and rotating image sliders look impressive but load slowly and often distract visitors.
Fix: Use one strong image instead. If you want video, let visitors choose to play it.
3. Too many add-ons
Chat widgets, pop-ups, social feeds, tracking scripts and fancy fonts each add a little weight. Together they add a lot.
Fix: Remove anything that doesn't directly help customers contact or buy from you.
4. Cheap or overloaded hosting
Very cheap hosting can be slow to respond.
Fix: If your site is simple but still slow to start loading, ask your host about performance options or consider moving.
5. Bloated themes and page builders
Some templates load code for hundreds of features you'll never use.
Fix: A lean, purpose-built site is often far faster than a heavy template.
Quick wins you can do this week
- Compress and resize every large image.
- Remove auto-playing video and sliders from your homepage.
- Delete unused plugins, widgets and pop-ups.
- Test again on PageSpeed Insights and compare.
Speed is a habit
Every time you add a photo, widget or new feature, check that your site is still fast. A fast, simple website that loads instantly on a phone will usually beat a slow, flashy one at turning visitors into customers.
