1. Kinsman and Co

Phone: +44 20 4602 5021

Business hours:

• Saturday and Sunday: Closed

Website

Kinsman & Co operates at a premium tier, delivering sophisticated campaigns without unnecessary complexity. A portfolio that includes household names such as Chanel and Dior reflects a high level of brand sensitivity and execution. This positioning is further reinforced by recognition as the Bespoke Full-Service Media Agency of the Year at the 2025 SME Business Awards.

The paid advertising division is particularly highly regarded, with clients noting precise audience targeting, transparent conversion tracking, and consistent returns on investment. The agency is characterised by a consultative approach, working in close collaboration with client teams to align creative execution with commercial goals.

In addition to search marketing, Kinsman & Co produces high-calibre digital assets, including video content and podcasts, to elevate brand positioning across digital channels. Retainer-based pricing models are tailored to media spend, which, whilst offering flexibility, makes them less suited to smaller enterprises seeking entry-level packages.

Their professionalism and expertise are evident in every aspect of their work

The Good Marketer focuses primarily on providing digital marketing services for small to medium-sized enterprises (SMEs). The agency is highly praised for a collaborative approach, with many clients noting that the team functions as a seamless extension of internal operations.

Communication is a key strength, marked by weekly reporting summaries, clear explanations of performance metrics, and absolute transparency regarding campaign results. The team possesses strong capabilities in paid advertising across Meta, TikTok, and Google, helping clients build brand awareness whilst driving consistent conversions. The broad range of services includes search engine optimisation, digital PR, and web development. However, the SME-focused model means the firm may not be the ideal choice for large corporations requiring complex international campaigns.

3. Passion Digital

Phone: +44 20 3432 1360

Business hours:

• Monday to Friday: 8:00 AM to 7:00 PM
• Saturday and Sunday: Closed

Website

Passion Digital is distinguished by an ability to merge creative campaign concepts with rigorous, data-driven analysis. The agency operates a flat, highly strategic structure, meaning clients work directly with experienced planners and specialists rather than junior account administrators.

The agency excels in both search engine optimisation (SEO) and pay-per-click (PPC) campaigns, with a strong history of long-term client retention. The service offering is exceptionally comprehensive, covering paid social media, content marketing, email campaigns, and Amazon advertising.

The team is also well-regarded for an ability to demystify complex technical concepts, making them a popular choice for non-profit organisations and charities navigating platforms such as Google Grants. A minor drawback is that some clients have reported slightly slow response times during the initial enquiry phase.

They helped us significantly improve our Google rankings

“I have worked with the team at Passion Digital for the last couple of years. They have done a fantastic job for us, helping to significantly improve our Google rankings and providing support and advice on all things SEO. They are a lovely group of people too, and have been a great extension to our team. Would 100% recommend.”
