Performance marketing measured in revenue

Most businesses do not have a marketing problem. They have a measurement problem. Budget goes out every month, reports come back full of clicks and impressions, and nobody can say which campaign produced a paying client.

Lead Gems is a specialist performance marketing agency based in London and Birmingham. We build growth systems for UK and worldwide professional service businesses and measure every one against a single number: revenue generated.

Our Story

Lead Gems was built on one belief: an agency should be judged by the revenue it generates, not the reports it sends.

We tested every system with our own money before offering it to a single client. That is still how we operate.

Our mission is simple. Give UK professional service firms a growth engine they can measure, trust and scale.

We hold ourselves to four standards: track everything, stay senior-led, report honestly, and never ask a client to take a risk we would not take ourselves.

What Sets Us Apart

We Test Every Strategy With Our Own Money

Before we recommend a strategy to a client, we have already run it with our own capital. Our proprietary lead generation brands use the same paid media, funnels and automation we build for clients. You get systems that are proven in the market, not theories from a pitch deck.

Tracking Before a Single Pound Is Scaled

Every engagement starts with server-side tracking, call tracking and offline conversion data. Each closed deal traces back to the keyword, ad or page that produced it. We only scale what the data proves is profitable, so your budget is never spent on guesswork.

Senior Specialists, No Junior Handoffs

You work directly with the specialists running your account across paid media, organic search, CRO and data. The people who pitch to you are the people who deliver for you. Reporting focuses on cost per qualified lead, cost per client and revenue generated.

Commonly Asked Questions

No. Our offices are in London and Birmingham, but we work with professional service businesses across the whole of the United Kingdom. Strategy sessions, reporting reviews and onboarding all run online, and every client gets the same senior team and the same standard of delivery wherever they are based.

Google PPC and paid social can generate enquiries within the first few weeks once tracking and landing pages are live. SEO is a longer investment and typically takes 6 to 12 months to build momentum, so we often run PPC while organic visibility grows. Timelines are indicative and vary by sector, competition and budget.

You work directly with senior specialists across paid media, paid social and CRO, organic search, and data and analytics. The people you meet during the sales process are the people who deliver your campaigns. There are no junior account managers between you and the work.

We measure what matters to your business: cost per qualified lead, cost per client acquired and revenue generated. Server-side tracking, call tracking and offline conversion data connect every closed deal to the campaign that produced it. Clicks and impressions are tracked, but they are never the headline.

We start with an audit of your existing tracking, campaigns, website and competitors. We then fix or rebuild tracking so every enquiry is attributed correctly, build or refine landing pages, and launch the first campaigns with controlled spend. Budget is only scaled once the data shows a profitable return.
