While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience.

Written by the company

Lead Gems is a specialist performance marketing agency operating from London and Birmingham, built for UK professional service businesses that need measurable, revenue-driven growth. We deliver across the full spectrum of digital performance: Google PPC, paid social advertising on Meta and LinkedIn, Search Engine Optimisation, AI Engine Optimisation, Geo-targeted SEO, landing page design and build, conversion rate optimisation, CRM setup and automation, and intelligent lead qualification. Every campaign starts with verified tracking. Every decision is tied to a commercial outcome. Every client works directly with a senior team from day one, with no junior handoffs and no vanity metrics in sight. We do not measure success in impressions or clicks. We measure it in qualified leads generated, cost per acquisition, and revenue returned against budget invested. Our clients are solicitors, accountants, financial advisers, dental practices, mortgage brokers, aesthetics clinics, and trades businesses across the UK. They come to us because previous agencies did not deliver. They stay because we do. If your marketing spend is not producing a clear, measurable return, that is exactly the problem we are built to solve.

Rated 5 out of 5 stars

Extremely happy with the partnership and would have no hesitation recommending Lead Gems.

As the owner of British Aesthetics School, one of the biggest challenges is knowing that you are investing heavily in advertising, but not necessarily getting the return you should be. That was one of the main reasons we decided to work with Lead Gems.

What stood out to me from the beginning was how they approached the business as a whole, rather than simply looking at our advertising accounts. They carried out a thorough audit, identified where we were losing opportunities throughout our funnels and really took the time to understand our business model, particularly the education side and the type of people we wanted to attract into aesthetic injectables training.

Their understanding of attribution, tracking and how everything connects from the initial advert through to an actual course enrolment is genuinely impressive. It is one thing to generate leads, but quite another to understand where those leads come from, what they cost and how many actually turn into paying students.

We have since seen a significant improvement in the quality of our enquiries, more conversions and a reduction in our cost per acquisition, all contributing to a much healthier return on our advertising spend.

As a business owner, what I appreciate most is having confidence in where our marketing budget is going and knowing that decisions are being made based on actual data rather than guesswork.

They are professional, incredibly thorough and clearly know what they are doing. It is rare to find an agency that understands both the technical side of performance marketing and the commercial realities of running and growing a business.

Extremely happy with the partnership and would have no hesitation recommending Lead Gems.
