Website Development Company London: Build a Site That Actually Generates Business

Your website is the hub of every marketing channel you run. Your SEO points people to it. Your ads send traffic to it. Your social posts link back to it. If it is slow, confusing, or unconvincing, every pound you spend on marketing is being wasted.

As a website development company in London, 100XREVENUE builds sites that are designed from the ground up to perform fast-loading, SEO-ready, conversion-optimised, and built to scale with your business.

What We Build

Business & Service Websites

For professional services, consultancies, and local businesses, we build clean, authoritative websites that communicate your value proposition clearly, establish credibility, and guide visitors towards a consultation or enquiry.

eCommerce Websites

We specialise in Shopify and WooCommerce builds for eCommerce brands that want more than just an online catalogue. Our eCommerce sites are built around conversion optimised product pages, streamlined checkout flows, and structured data that helps products rank in Google Shopping.

Landing Pages & Funnel Pages

High-converting landing pages for paid campaigns, lead generation, and product launches. Built with a single goal in mind and tested for conversion performance.

What Makes a High-Performing Website in 2025?

Speed

Google’s Core Web Vitals are now a direct ranking factor, and user data is unambiguous: every second of additional load time reduces conversion rates. We build sites that load in under 2 seconds on mobile by default.

Mobile-First Design

More than 60% of UK web traffic comes from mobile devices. We design for mobile first and ensure the experience is flawless on every screen size.

SEO Architecture

We build site structures with organic search in mind clean URL hierarchies, proper heading usage, schema markup, and technical foundations that make it easy for Google to crawl and understand every page.

Conversion-Focused UX

Every design decision layout, copy, CTA placement, trust signals is made with conversion in mind. We use CRO principles throughout the build rather than applying them as an afterthought.

Your website is the foundation that every other marketing channel depends on. Once your new site is live, our SEO Agency London team builds on the technical architecture we put in place during development to grow your organic visibility, while our Google Ads Management service can start driving high-intent traffic from day one long before organic rankings begin to take effect.

We also ensure your site continues to improve after launch. Our Conversion Rate Optimisation service systematically tests and improves your conversion rate using real visitor data, all of which is captured and measured accurately through our Google Analytics Setup & Conversion Tracking service.
