Website Speed, SEO and Enquiries: What Actually Matters
Every few months a business in Edinburgh is told its website is slow and that this is why it isn't ranking. Sometimes that's fair, often it's oversold. We build and host business sites, so we know where the time really goes — this is what site speed does, what it doesn't, and how to find out where your own time is going.
Speed is a ranking input, not the ranking
Google says page experience, including speed, is one of many signals it uses. One of many is the important part. If a competitor outranks you, the likeliest reasons are still that their page matches the search better, covers the subject properly, or is trusted more widely. Speed rarely lifts a weak page above a strong one. Where it counts is as a tie-breaker between pages that are otherwise close, and as a floor: a site that's genuinely painful to use can be held back. Fix speed because it makes the site better for people, and treat any ranking benefit as a bonus.
What Core Web Vitals actually measure
Core Web Vitals is Google's name for its user-experience metrics, and it's worth knowing what the three parts describe rather than chasing a score.
- Largest Contentful Paint. How long until the main thing on the page — the hero image or headline — has actually appeared.
- Interaction to Next Paint. How quickly the page responds when someone taps or clicks, rather than sitting there looking frozen.
- Cumulative Layout Shift. How much the page jumps about while loading. This is the one that makes you tap the wrong button.
Google publishes target values for each and revises them, so check the current figures at the source rather than a number in a blog post, including this one.
Why it matters for enquiries, not just rankings
The commercial case is simpler than the SEO one. People arriving from a search have no investment in you yet, and a blank screen gives them nothing to wait for. They go back and try the next result. That loss is invisible: it never shows up as a failed enquiry, only as traffic that didn't convert. Mobile makes it sharper: much local searching happens on patchy signal on the move, and a phone hunting for 4G somewhere between Livingston and Bathgate is the real test condition, not your office fibre.
Images are usually the culprit
When a small business site is slow, the usual cause is photographs loaded straight off a camera or phone. A modern phone photo can be several megabytes and thousands of pixels wide, shown in a box a few hundred pixels across. The visitor downloads all of it. Resize images to roughly the size they're shown at, compress them, use a modern format such as WebP where you can, and set width and height so the browser reserves the space — which also deals with a lot of layout shift. That one job often does more good than every other tweak put together.
Scripts, plugins and third parties
The second common cause is accumulation. A chat widget, two analytics tags, a cookie banner, a review carousel and a booking embed each seemed reasonable on the day. Together they can outweigh your actual page, and third-party scripts run on someone else's servers, so their bad day becomes yours. Audit what's loading, remove anything you no longer look at, and be honest about which plugins earn their keep. Fewer moving parts also means better security: every add-on is another thing to keep patched.
Hosting and caching
Underneath all that sits the server. Cheap shared hosting puts many sites on one machine, so your response time depends partly on your neighbours. Caching stores a ready-made copy of a page instead of rebuilding it for every visitor, and it is often the single biggest improvement available on a database-driven site. Ask any host, ourselves included, about caching, current software versions and where the servers physically are, and put the real renewal cost into your IT budget, not the introductory one.
Test it properly before you spend
Measure before changing anything. Google's PageSpeed Insights gives you lab data, from a simulated load, and field data from real visitors where there's enough traffic — the field data is the one that matters. Search Console reports the same vitals site-wide, which shows whether it's one bloated page or the lot. Test on mobile, and on a page that matters commercially, not just the home page. And rule out your own end first: a site can feel slow because of your office wi-fi or a machine that needs attention, and no amount of work on the website will fix either.
We can look after the site too
We're based in Wishaw and work with businesses across Edinburgh and the Lothians. We design and host business websites, keep existing WordPress sites patched and quick, run email hosting and plan Microsoft 365 moves, alongside business IT support and managed IT services for the kit and the connection behind it all. Tell us what the site has to do and you'll have a clear quote before any work starts.
