Why a slow website is costing your Norwich business enquiries (and how to fix Core Web Vitals)

A slow website does not announce itself. Nobody emails to say they left because a page took five seconds to appear. They simply tap back to the search results and choose a competitor. Studies across the web consistently show that conversion rates fall as load time rises, and that mobile visitors abandon slow pages fastest of all. For a local business spending money on Google Ads or working hard on SEO, a slow site means you are paying to send people to a page that loses a share of them before they ever see your work.

• Every extra second of load time tends to reduce the percentage of visitors who enquire.
• Paid traffic is wasted when the landing page is too slow to hold the click you paid for.
• Slow pages increase bounce rate, which weakens the signals search engines use to rank you.
• The damage is invisible in most analytics unless you are specifically looking for it.

Core Web Vitals are the three speed and stability metrics Google uses as part of how it ranks pages. Largest Contentful Paint measures how quickly the main content appears. Interaction to Next Paint measures how quickly the page responds when someone taps or clicks. Cumulative Layout Shift measures how much the page jumps around as it loads. Together they describe what a real visitor feels: does the page show up fast, react fast, and stay still while I use it. Passing all three is not about chasing a perfect score, it is about removing the friction that makes people give up.

Local searches often happen on a phone, on mobile data, in the middle of doing something else. Someone looking for an emergency plumber, a quote for a new roof, or a nearby studio to redesign their website is rarely browsing for fun. They want an answer now. That impatience is an opportunity. If your website loads instantly and makes the next step obvious while a competitor stalls on a heavy page, you win the enquiry before the comparison even begins.

Most slow websites are not slow by accident. They are slow because of how they were built. Heavy page builders, bloated themes, oversized images and a long queue of third-party scripts all add weight. The more plugins and tracking tags a site carries, the more work a phone has to do before anything useful appears. Fixing speed is usually less about one magic setting and more about removing the accumulated weight that was never needed in the first place.

• Large, uncompressed images that were never sized for the web.
• WordPress themes and page builders that load far more code than the page uses.
• Too many plugins, marketing scripts and chat widgets firing on every page.
• Cheap shared hosting that responds slowly under load.
• No caching, so the server rebuilds the same page for every single visitor.

At Mousehold Studio we build sites to be fast from the first line of code rather than trying to rescue speed at the end. That means lean, modern code instead of bloated templates, images compressed and served in next-generation formats, only the scripts that genuinely earn their place, and hosting and caching tuned so pages are delivered quickly across the UK. A fast website is not a one-off achievement either. New content, new images and new tracking tags can all slow a site over time, which is why ongoing care matters.

• A clean, modern build instead of a heavy off-the-shelf theme.
• Images compressed and served in formats like WebP without losing quality.
• Careful control over third-party scripts so marketing tags do not wreck performance.
• Caching and fast hosting so pages load quickly for repeat and first-time visitors.

You do not need to guess whether your site is fast. Free tools give you a clear picture in minutes. Google PageSpeed Insights reports your Core Web Vitals and shows what is slowing each page down. The key is to test on mobile, not just desktop, because that is where most local visitors and the toughest performance conditions are. Look beyond the headline score at the specific issues it lists, because that is where the real fixes live.

• Run your most important pages through Google PageSpeed Insights on the mobile setting.
• Check the three Core Web Vitals rather than fixating on a single overall number.
• Test your home page, your top service page and your main Google Ads landing page.
• Compare your speed against a competitor you keep losing enquiries to.
