A slow website loses customers because visitors leave before the page finishes loading, Google ranks slow pages lower, and a sluggish site feels untrustworthy — especially on mobile, where most buyers now do their first research. The good news: most speed problems come from a short list of fixable causes, and this checklist walks through all of them.
Key takeaways
- Visitors judge your site in seconds; slow pages lose them before they read a word.
- Google uses page speed in rankings, and most B2B research now starts on a phone.
- Images are the biggest cause of slow pages — compress them first.
- Aim for the key content visible in under 2.5 seconds on mobile (Google's Core Web Vitals threshold).
- Speed alone isn't enough: every page also needs an obvious, one-tap way to contact you.
Visitors decide very quickly whether a website is worth their time. If a page loads slowly or is hard to use on a phone, many leave before they read a single word — and they rarely come back. Speed also matters for SEO, because Google considers page experience when ranking results. For businesses selling to overseas buyers, there's an extra factor: your visitor might be on a slower connection in another country, so a site that feels "fine" in your office can feel broken to the buyer who matters.
How exactly does speed cost you enquiries?
Think about the journey of a buyer who finds you on Google. They tap your result, and then they wait. Every second of waiting is a moment they reconsider — maybe they go back and tap your competitor instead. A slow site doesn't just lose the impatient; it loses trust. Buyers unconsciously read speed as competence: a supplier whose website struggles to load doesn't inspire confidence about production timelines or export paperwork.
Then there's the compounding effect. Slow pages rank lower, so fewer buyers arrive. The ones who arrive convert worse. And the analytics get polluted — high bounce rates that look like a content problem are often a speed problem in disguise. Fixing speed is one of the rare improvements that lifts traffic and conversions at the same time.
How fast should your website be?
You need a target, or "faster" never ends. Google's Core Web Vitals give you public benchmarks worth aiming for: the main content should be visible within 2.5 seconds (Largest Contentful Paint), the page should respond to taps in under 200 milliseconds, and the layout shouldn't jump around while loading. You don't need perfect scores — but if your key pages miss these thresholds on mobile, you're leaving enquiries on the table.
Test with Google PageSpeed Insights (free) on the mobile tab — that's the score that matters, since desktop almost always scores higher and flatters you. Test your homepage, one product or service page, and your contact page. Write down the three scores; that's your baseline. Re-test monthly, because sites get slower over time as images, plugins and tracking scripts accumulate.
What actually makes websites slow?
In our experience, the causes are almost always the same short list. Oversized images are number one: a 4MB banner photo where a 200KB one would do, or PNGs used where modern formats would be a tenth of the size. Next come unused plugins and scripts — every chat widget, slider, animation library and tracking pixel adds loading time, and most business sites carry several they no longer need.
Then there's hosting: cheap shared hosting far from your buyers means every request travels further and waits longer. A content delivery network (CDN) fixes this by serving your pages from servers near the visitor — essential if you sell internationally. Finally, the quiet killers: no caching (so every visit rebuilds the page from scratch), videos that auto-load, and web fonts pulled from slow third-party servers. Work through the table below in order; the first three rows fix the majority of slow sites.
| Problem | The fix | Effort |
|---|---|---|
| Oversized images | Compress all images; use WebP format; size them to their display dimensions | Low — biggest win |
| Unused plugins and scripts | Audit everything loading on the homepage; remove what you don't need | Low |
| Slow or distant hosting | Move to good hosting and add a CDN so pages load fast in every buyer country | Medium |
| No caching | Enable page caching so repeat visits load instantly | Low |
| Below-the-fold media loading upfront | Lazy-load images and videos; never auto-play video with sound | Low |
| Heavy fonts and sliders | Use system fonts or one font family; replace sliders with a single strong image | Medium |
Is your site easy to use on a phone?
Speed gets the buyer to your page; mobile usability keeps them there. Most B2B buyers now do their first supplier research on a phone — on a commute, at a site, between meetings. If your site needs pinching and zooming, they'll leave for a competitor whose site doesn't.
- Text readable without zooming. Body text should be legible at arm's length on a phone screen.
- Buttons large enough to tap easily. Contact and WhatsApp buttons should be thumb-sized, with space around them.
- No content wider than the screen. Horizontal scrolling is an instant exit — check tables and images.
- Menus that are simple to open and close. If a buyer can't reach your product pages from the menu in two taps, the menu is broken.
- Forms that work one-handed. Short forms, large fields, and a keyboard that matches the field (email keyboard for email).
Can a visitor contact you from every page?
A fast, mobile-friendly site still loses customers if the enquiry path is hard. This is the conversion half of the checklist, and it's where most business sites quietly fail.
- A clear headline on every page that says what you do and for whom — not "Welcome to our website".
- WhatsApp, email or enquiry buttons visible on every page, ideally sticky on mobile so they're always one tap away.
- Contact details that are correct everywhere — footer, contact page, and any listings. One wrong number destroys trust.
- A clear next step at the end of every page: "Message us on WhatsApp for a quote" beats a dead end.
- Reply fast when they do contact you. A same-day reply doubles your chance against slower competitors — see our guide on getting overseas buyers from Google for what happens after the click.
How do you make buyers trust you in seconds?
Speed and usability get buyers to stay; trust gets them to enquire. Three elements do most of the work. First, HTTPS with a valid certificate — browsers now warn visitors away from non-HTTPS sites, and no buyer sends an enquiry through a "Not secure" page. Second, real photos: your products, your team, your work — stock photos are spotted instantly and signal a business with nothing real to show. Third, clear specifics: what you offer, where you deliver, how to reach you. Vague claims ("best quality, best price") build no trust; concrete details do.
If you sell internationally, add the trust signals overseas buyers look for: export markets served, certifications, and a straightforward way to start a conversation. Our website design service builds all of this in from the first draft — and our pricing is public, because hidden prices are themselves a trust problem.
How do you keep your site fast over time?
Sites don't stay fast by accident. New images get uploaded uncompressed, new plugins get added "temporarily", tracking scripts multiply. Put a monthly ten-minute check on the calendar: run PageSpeed Insights on your three key pages, compare against your baseline, and fix anything that slipped. When adding new content, compress images before uploading — not after. And once a quarter, audit what's loading on the homepage; if you can't name what a script does, remove it and see if anything breaks. If you would rather have an expert baseline, a technical SEO audit covers speed, mobile and crawl issues in one pass.
We build fast, SEO-ready websites with all of this built in — speed budgets, mobile-first layouts, and enquiry paths on every page. See our website design service, or ask for a free website review and we'll show you exactly what's slowing your site down and what it's costing you.
