A Hackney independent optician had a website built in 2019 on a page builder. It scored 31 on Google PageSpeed. The booking form was buried four clicks deep.

The practice was spending £600 a month on Google Ads. Their Google Ads account manager kept recommending they increase the budget. The actual problem was that the website was converting at 0.8%: of every 100 people who clicked their ad, fewer than 1 booked an appointment. The slow load time alone was responsible for the majority of drop-off, with 68% of visitors leaving before the page finished loading on mobile.

A full rebuild from clean HTML and CSS produced a site that scored 94 on PageSpeed, loaded in 1.2 seconds on mobile, and had the booking form visible above the fold on every device. The same £600 Google Ads budget produced 34 bookings in month one, compared to 6 the month before. The site also began ranking organically for 'optician Hackney' within 10 weeks of launch.

34 bookings from the same £600 ad budget. PageSpeed 31 to 94. Organic rankings within 10 weeks.

Why most London small business websites do not convert

Most small business websites in London were built by someone who prioritised how they look over how they perform. They are built on page builders that produce hundreds of kilobytes of CSS and JavaScript for a five-page site. They load slowly on mobile, which is where more than 60% of London local searches happen. The call-to-action is at the bottom of a long scroll. The phone number is in the footer. The homepage headline describes what the business does rather than what the customer gets. Each of these problems individually costs conversions. Together they explain why a business can be spending £1,000 a month driving traffic to their site and getting two enquiries a week from it.

Your website is your most important sales tool. It works 24 hours a day, seven days a week, and it never asks for a commission. The question is whether it is actually selling.

Core Web Vitals are now a confirmed Google ranking factor. A slow site does not just lose conversions: it loses rankings. The fastest websites on mobile get preferential treatment in Google's index. For London local search, where map pack and organic positions determine most of the traffic, a site that fails Core Web Vitals is actively being penalised compared to competitors who pass them.
STAT
A one-second delay in page load reduces conversions by 7%. For a London business getting 200 website visitors a month and converting at 3%, that one second costs roughly 4 enquiries per month. Most small business sites built on page builders load in 4 to 7 seconds on mobile. The conversion cost is not hypothetical.

In London's local market, your website is competing against businesses that have invested in performance. A slow site on a page builder is not neutral: it actively loses rankings to faster competitors and loses conversions to clearer ones. The businesses with the highest organic visibility and the lowest cost per lead almost always have the fastest, clearest websites.

for London businesses

Websites built to convert the traffic your marketing generates, rank on Google without needing constant fixes, and load fast on every device.

New website design and build

Full website design and development from brief to launch. Clean HTML, CSS, and JavaScript or lightweight WordPress depending on your content management needs. No page builders. Fixed-price scope agreed upfront. Launch in 4 to 6 weeks for standard projects.

Website rebuild and redesign

Rebuilding an existing site that is slow, unclear, or converting poorly. We audit what is wrong, agree on the scope of the rebuild, protect your existing Google rankings through the migration, and deliver a faster, clearer version of your current site with measurably better conversion.

Landing page development

Single-purpose landing pages for Google Ads campaigns, SEO targeting, or specific service offers. A dedicated landing page for each campaign consistently outconverts a homepage by 3 to 5 times. We build, test, and optimise them as part of your paid search campaigns.

Core Web Vitals optimisation

Fixing existing sites that are failing Google's performance benchmarks. We diagnose slow load times, Cumulative Layout Shift, and Interaction to Next Paint issues and fix the underlying causes rather than masking them. Passing Core Web Vitals improves both rankings and conversions.

SEO-ready site architecture

URL structure, internal linking, heading hierarchy, schema markup, XML sitemaps, and canonical tags configured correctly from day one. A site built with SEO architecture baked in ranks faster than one that has SEO retrofitted after launch. We build both simultaneously.

Ongoing support and updates

Monthly support retainers covering updates, new pages, conversion rate testing, and performance monitoring. Your website is not a one-off project: it is a sales tool that should be improving month on month based on what the data shows about visitor behaviour.

Questions from London businesses about web development

How much does a new website cost in London?
A professionally built small business website in London typically costs between £2,500 and £8,000 depending on scope. That includes design, development, copywriting, and SEO setup. E-commerce sites with catalogue management, payment integration, and order management start around £5,000. We provide fixed-price quotes after an initial scoping call so there are no surprises.
How long does it take to build a website?
For a standard 8 to 12 page business website, our typical timeline is 4 to 6 weeks from signed brief to launch. That includes design, development, content, and a review and revision phase. E-commerce projects take 6 to 10 weeks. The biggest factor affecting timeline is how quickly we receive content, images, and feedback from the client.
Will my new website rank on Google?
A website built by us has technical SEO built in from the start: correct URL structure, fast page speed, proper heading hierarchy, schema markup, XML sitemap, and meta tags. This is the foundation. Ranking for competitive terms in London requires ongoing SEO work beyond the build, which we offer as a separate retainer. A well-built site is the prerequisite; SEO is what drives it up the rankings.
Do you use WordPress or custom code?
It depends on the project. For marketing websites where speed, security, and SEO performance are the priority, we often build with clean HTML, CSS, and JavaScript without a CMS. For clients who need to manage content themselves, we use WordPress with a lightweight theme. We do not use page builders like Elementor or Wix as they produce slow, bloated sites that underperform on Core Web Vitals.
Can you redesign an existing website without losing our Google rankings?
Yes, and protecting your existing rankings during a redesign requires specific technical steps: 301 redirects for any changed URLs, preserved meta tags and structured data, maintained page speed, and a crawl check before and after launch. We have a standard migration checklist that covers all of this. Losing rankings during a redesign is common when these steps are skipped; we do not skip them.
