Top Digital Marketing Agencies In Cardiff For 2027

Cardiff has a compact but capable marketing scene, where a handful of agencies run SEO, paid media, social and content under one roof for Welsh and UK brands.
To build this list we checked each firm’s own website, reading its contact and about pages to confirm a real street address in Cardiff, a live site with 2025 or 2026 activity, and digital marketing as a genuine core service rather than a side offer. We left out firms that only run a Cardiff landing page while working from elsewhere, directories and marketplaces, and any agency we could not verify. Pure web design studios that already feature on our Cardiff web design list were also left out, so this list leans towards marketing-led firms. If you are searching for a digital marketing agency Cardiff has plenty of choice, but far fewer firms that publish clear evidence of their work.
Each entry covers where the agency is based, what it does and how it works, the evidence it publishes (named clients, results, team size, accreditations), any published pricing, and the kind of business it suits best.

Best Digital Marketing Agencies In Cardiff
1. Liberty Marketing — Full-Service Search, Paid Media And Content Agency Founded In 2008
Liberty Marketing works from 1-2 Purbeck House on Lambourne Crescent in Llanishen, in the north of Cardiff. The agency was founded in 2008 by Gareth Morgan, now Group CEO, and its about page says it employs more than 40 staff, which makes it one of the larger independent marketing teams in the city.
Its service list covers most of what a growing brand needs online. Paid media runs across Google Ads, Google Shopping, Microsoft Ads, Facebook, LinkedIn and X, along with display, remarketing and programmatic buying. The SEO team handles technical audits, site migrations, local and international search, and newer AI search work. Content, organic social media, digital PR and training round out the offer.
The agency publishes named client work. For San Carlo, a local SEO plan and an improved booking journey are credited with more than 10,000 organic reservations and over £1m in December revenue during a Christmas campaign. It also says it helped Happy Beds grow from a local manufacturer into one of the UK’s largest online bed retailers. Its blog carries current pieces on Google’s 2026 search changes and ChatGPT ads. Pricing is quote-based.
It suits retail, hospitality and ecommerce brands that want SEO, paid media and content run by one sizeable team.
2. Golley Slater — Employee-Owned Integrated Agency With Public Sector Campaign Results
Golley Slater has a Cardiff office at Wharton Place, 13 Wharton Street, in the city centre, with further offices in Cirencester, Leeds and London. The agency says it has become employee-owned, and it is the most traditional firm on this list, combining advertising and media buying with digital channels.
Its services include advertising and creative, B2B marketing, branding, content and film, CRM and automation, media planning and buying, PR, social and influencer marketing, research and planning, retail marketing and SEO. That breadth lets it run a single campaign across paid, owned and earned channels rather than handing pieces to separate suppliers.
The client roster on its site includes Transport for Wales, Welsh Government, NHS Wales, Cadw, Welsh Water, Bluestone, Zip World, Royal Mint and S4C, alongside national names such as Tesco, Nationwide and Procter & Gamble. Its “No Second Chances” rail safety campaign for Transport for Wales is credited with a 50% fall in trespassing on South Wales lines and a 17% rise in awareness, and the work picked up five wins at national campaign awards. The site also reports a Grand Prix at the Drum Recommends Awards 2021. Pricing is not published.
It suits public bodies, tourism operators and larger consumer brands that need integrated campaigns with media buying behind them.
3. WCS Agency — Social-First Marketing And PR Agency For Welsh Venues And Brands
WCS Agency is based at Dolphin House on Church Street in central Cardiff. Founded and led by Chelsea Pinches-Burrowes, it describes itself as a Cardiff-born marketing, PR and creative agency with a 15-strong team, and it also owns Cardiff Life Magazine and the Cardiff Life Awards. It is listed as an IPA accelerator agency, where it is described as full-service and social-first.
Services cover social media management including TikTok, paid social, PR and communications, creative and video production, strategy, events and influencer work, plus Google Ads and SEO. Most clients come from hospitality, retail, venues, property, culture and the public sector.
The named client list is long and local: Wales Millennium Centre, Glamorgan Cricket, Royal Mint, Cardiff City FC, The Ivy, The Celtic Collection, Hugh James and Principality Stadium all appear. Recent posts from October 2026 describe keeping cost per click under 40p for nine months for a Cardiff estate agent and a seven-day paid campaign the agency reports returned 11,900%. The site shows a 4.9 rating from more than 234 reviews and Google Partner status. Pricing is quote-based, with both retainer and project work.
It suits hospitality groups, venues and consumer brands in Wales that want social, PR and paid media from one team.
4. Station Rd. Marketing — B Corp Marketing Agency Combining Strategy, Search And Paid Social
Station Rd. Marketing is based at Clockwise Offices in Brunel House, 2 Fitzalan Road, in Cardiff city centre. Its site describes it as a B Corp certified marketing agency, which will matter to buyers who want a supplier with published social and environmental standards.
The agency groups its work into three stages. Evolve covers director-on-demand support, workshops, audits, data and planning. Amplify covers creative, CRO, HubSpot, Shopify and WordPress builds, and web design. Impact is the delivery layer: content and PR, email, paid social, SEO and paid search. There is also a brand and communications strand that includes reputation and crisis management, and advice on marketing technology.
Named clients on its site include Barbri, Titania, Woodpecker Flooring, Llanishen High School, the charity With You and Vocation Brewery, where the agency ran Google and Meta advertising to drive online sales. The case studies describe the work rather than publishing figures. Pricing is not published.
It suits purpose-led SMEs, education providers and charities that want senior strategy and hands-on channel delivery from the same agency.
5. Caffeine Marketing — Integrated SEO, Google Ads And Social Agency In Capital Tower
Caffeine Marketing works from the third floor of Capital Tower on Greyfriars Road in Cardiff city centre. The agency says it was founded in Cardiff more than a decade ago and has worked with over 100 businesses across more than 60 sectors.
Its core services are SEO, Google Ads and PPC, social media marketing, content marketing and website design, and it pitches them as an integrated plan rather than separate retainers. The agency holds Google Partner, LinkedIn marketing partner and Meta Business Partner status, which covers the three ad platforms most of its clients use.
Testimonials on the site come from Clarity Software, Capital Equipment, Mallard, Scarlets and RISG. Its case summaries are anonymised and describe outcomes such as a steadier monthly flow of enquiries for a professional services firm, lower acquisition costs for a consumer brand, and stronger commercial rankings for a B2B specialist, without publishing numbers. The blog is active, with recent posts on how AI is changing SEO and why Cardiff businesses need more than a website. Pricing is quote-based.
It suits B2B, professional services and regional consumer brands that want lead generation across search and social handled together.
Jos Davies runs a one-person consultancy from 108 Taff Embankment, Cardiff, trading through Jadeite Marketing Ltd. It is the smallest option here and works differently from an agency: Jos is brought in as a senior freelance consultant, often alongside an in-house team, and draws on more than 20 years in digital marketing.
The consultancy covers SEO, PPC, search marketing, social media consultancy, content strategy, conversion rate optimisation, site migrations and analytics. Channels listed include Facebook and Instagram Shopping and YouTube advertising. Qualifications shown on the site include the IDM Postgraduate Diploma in Digital Marketing, Google Ads Search certification and the Chartered Institute of Marketing GA4 qualification.
The client list is unusually strong for a solo practice. Testimonials come from Admiral Group, Leaders Romans Group, ManyPets, Wealthify and Realpoint Italy, and logos for Longleat, Agria and Jottnar appear on the site. The Admiral testimonial credits the work with helping the insurer reach the top organic position among UK insurers. Results are described rather than quantified, and pricing is quote-based.
It suits insurers, financial services firms and in-house marketing teams that need senior search, analytics or migration expertise without an agency retainer.
7. New Media Ghost — Strategy-Led Content And AI Search Visibility Agency On Bute Street
New Media Ghost is based at Portland House, 113-116 Bute Street, between Cardiff city centre and Cardiff Bay. It is a smaller agency built around marketing strategy, with content and websites delivered to fit that plan.
Its four service areas are marketing strategy and planning, content creation, website development and AI search visibility, which covers how a business appears in tools such as ChatGPT and Google’s AI results. The agency focuses on technology and SaaS, construction, marine engineering and private practice surgeons, sectors where buyers research carefully before making contact.
Named testimonials come from the chief executives of WHA Healthcare and Harris Pye Engineering Group. The Harris Pye testimonial describes an international rebrand completed within 12 weeks, with the team travelling to the group’s major overseas offices to roll it out. The site is regularly updated, with 2026 blog posts on AI search visibility and free guides including a search visibility guide and a business marketing toolkit. Pricing is quote-based.
It suits B2B firms, engineering groups and private clinics that want a clear strategy and content programme more than high-volume ad management.
How To Choose A Digital Marketing Agency In Cardiff
Are They Actually Based In Cardiff?
Many national agencies publish Cardiff pages without having anyone in the city. Ask for a street address and check it against the contact page and Companies House. Every agency on this list publishes a Cardiff address, from Capital Tower (Caffeine Marketing) to Dolphin House (WCS Agency) and Llanishen (Liberty Marketing). A local team matters most if you want face-to-face planning sessions or work tied to Welsh events and venues.
Do You Need Full Service Or A Specialist?
Digital marketing agencies in Cardiff range from large integrated teams to single consultants. Golley Slater and Liberty Marketing can run SEO, paid media, social and PR together, which reduces handovers. A consultant such as Jos Davies is better when you already have an in-house team and need senior expertise in one area. Decide which channels you want the agency to own before you start talking to firms.
What Does Digital Marketing Cost In Cardiff?
None of the agencies here publish retainer prices. As a typical UK market range, small businesses buying digital marketing Cardiff agencies provide tend to pay around £750 to £2,000 a month for one or two channels, while multi-channel retainers covering SEO, paid media and social usually run from £2,500 to £8,000 a month. Ad spend is on top of management fees, and senior consultants usually charge day rates of roughly £400 to £900.
Can They Show Named Results?
Ask for case studies with client names and numbers. Liberty Marketing publishes San Carlo reservation figures, Golley Slater reports the trespass reduction from its Transport for Wales campaign, and WCS Agency publishes cost-per-click results. If an agency can only describe anonymised outcomes, ask to speak to a current client.
What Contract Terms Should You Expect?
Most retainers start with a three to six month minimum term, followed by a rolling monthly notice period. SEO usually needs three to six months to show meaningful movement, while paid media can produce data within weeks. Confirm who owns the ad accounts, analytics and content, and agree reporting dates before signing.
Liberty Marketing is the strongest all-round choice for brands that want a large team covering SEO, paid media and content. Golley Slater fits public sector bodies and big consumer brands that need integrated campaigns and media buying. WCS Agency is the pick for venues and hospitality groups that live on social, while Station Rd. Marketing suits purpose-led SMEs that want strategy and delivery together. Caffeine Marketing works well for B2B lead generation, Jos Davies for in-house teams needing senior search advice, and New Media Ghost for specialist B2B firms focused on content and AI search.
Before you sign with any digital marketing agency in Cardiff, check five things: a verifiable Cardiff address, named case studies with figures, who will actually work on your account, who owns your ad accounts and data, and the minimum term and notice period.
