Meta description: Looking for an SEO agency Belfast firms rate? We compare 10 verified local agencies with addresses, specialisms, named results and published pricing in £.
Belfast businesses often sell into several markets at once. A retailer on the Lisburn Road or a solicitor in the Linen Quarter may need to rank in Northern Ireland, in Great Britain and in the Republic, often with different search behaviour, currencies and competitors in each. A local agency that understands that mix, and can meet you in the city centre, is worth more than a remote firm running a “Belfast SEO” landing page with no desk here.
To build this list of the top SEO agencies in Belfast, we checked every firm against its own contact and about pages. Each one has a verified Belfast address, a live website with current activity, and SEO as a real practice rather than a single line on a web design price list. Where useful, we cross-checked company details at Companies House. We excluded firms working mainly in gambling, adult or crypto niches, and left out any claim we could not confirm.
Each entry covers where the agency is based, what it does and who it suits, plus verified details such as founding year, team size, named clients, awards, published results and pricing where the agency shares them.

Best SEO Agency Options In Belfast
1. Loud Mouth Media — UK Agency Awards Integrated Search Agency Of The Year From A College Square Head Office
Loud Mouth Media is headquartered at The Kelvin, 17 College Square East, BT1 6DE, in the city centre. It also runs offices in Glasgow, London and Dublin. Companies House lists Loud Mouth Media Ltd at that Belfast address, incorporated in August 2011.
The agency describes digital advertising as its speciality, and its SEO practice sits inside that performance focus. The SEO service covers technical audits, keyword research, on-page optimisation, content, local SEO with dedicated teams in Belfast and Glasgow, and a separate strand for visibility in generative AI and LLM search.
Named clients include Lyle & Scott, SSE Airtricity, Autoline Insurance, YouFibre and Milk & Blush. One published SEO result for SSE Airtricity reports a 15% year-on-year rise in organic traffic and a 13% rise in conversions.
At the 2024 UK Agency Awards it won both PPC Agency of the Year and Integrated Search Agency of the Year, a result reported by Adworld. Pricing is quote-based. It suits established brands that want SEO and paid search run by the same team.
2. ProfileTree — SEO, Content And Training For SMEs With Published Retainer Bands
ProfileTree is based at the McSweeney Centre, 31 Henry Place, BT15 2AY, in north Belfast. The business has traded since 2011, when Profile Tree LLP was registered at Companies House, and Ciaran Connolly is its founder.
Web design is a large part of the business, but SEO has its own process. A discovery audit takes five to seven working days and is delivered before any contract is signed. Campaigns then follow a twelve-month roadmap with KPIs set for months three, six and twelve, and initial agreements run for six months. The service covers technical audits, on-page work, content written to be cited in AI search tools, link building through editorial placements, and local SEO for Belfast and Northern Ireland.
ProfileTree publishes retainer bands: foundational SEO at £1,000 to £1,500 a month and growth-stage campaigns at £2,000 to £3,500, with enterprise work priced above that. Named clients include Tourism Northern Ireland and the Ulster Orchestra. It won at the Irish Content Marketing Awards for its ConnollyCove project. Its training offer makes it a good fit for SMEs that want to learn to run some SEO in-house.
3. Codefixer — Senior SEO And Google Ads Specialist On Malone Road
Codefixer works from 17 Malone Road, BT9 6RT, a short walk from Queen’s University. The agency says it specialises in SEO and Google Ads, and its SEO work is led by Michael Wall, whom it describes as one of Ireland’s longest-serving SEO and pay per click specialists. Companies House lists Codefixer Ltd at the Malone Road address.
The SEO service covers local SEO and Google Business Profile, ecommerce SEO, audits, keyword and competitor research, site migrations and 301 redirects, link building and Google penalty recovery.
Named clients include ICC Belfast (Waterfront Hall and Ulster Hall), Power NI, Brett Martin, Eakin Healthcare and Boyd-Rice Solicitors. Its published case studies report a 745% rise in non-brand clicks for an electricity supplier, a campaign shortlisted at the UK Search Awards, and £171,000 in annual SEO revenue for a heating appliances retailer. A private healthcare clinic in Northern Ireland saw organic enquiries rise 324%. It was also a DNA Awards finalist. Pricing is on enquiry. It suits businesses that want experienced hands rather than a large account team.
Platform Marketing Agency is based in The Penthouse, 23a Donegall Road, BT12 5JJ, just off Shaftesbury Square. It describes itself as established in 2010, and the current company, Platform Marketing Agency Ltd, is registered at the same address at Companies House.
Alongside branding, video and podcast work, its digital marketing team runs technical SEO, keyword research, on-page work, content, local SEO and audits.
What sets Platform apart is clear, published pricing. The Starter package costs £350 a month and covers an audit, keyword research, on-page work on up to four pages, technical SEO and a monthly ranking report. Growth, at £700 a month, adds local SEO, two content pieces a month, schema markup and optimisation for AI answer engines. Scale, at £1,000 a month, adds competitor analysis, AI visibility audits and entity optimisation. All packages start with a six-month term.
Published results include an 824% increase in clicks in six months for IFS Global Logistics and a 600% rise in leads in two months for PWS Signs. It suits small businesses that want to know the monthly cost before the first call.
5. Vudu Digital — Local SEO For Service Firms And Retailers With A £500 To £2,500 Guide Price
Vudu Digital has offices at 11a Wellington Place, BT1 6GB, beside City Hall, and at Colvin House in Dundonald, BT16. The agency says it has been established since 2008 and reports 99% client retention.
Its SEO service covers on-page optimisation with keyword research for each page, technical and local SEO, Google Business Profile work, link acquisition and regular reporting, plus a free audit for sites that are struggling or have been penalised.
Named clients include Food Solutions Limited, Johnson’s Solicitors, P.A. Duffy & Co Solicitors, Mackey Opticians, McNeill Hotelware, Lyric HiFi and Tribal Burger. Vudu publishes two SEO results: Serendipity Bridal saw website traffic rise 125% and enquiries rise 90% within six months, and Food Solutions Limited grew online sales 250% over six months.
The agency also publishes a guide price, suggesting £500 to £2,500 a month for local or regional SEO in Northern Ireland, with larger ecommerce and national campaigns costing more. It suits solicitors, clinics, retailers and other local firms that want SEO and a website from the same team.
6. Rane Digital — Web, SEO And PPC For Heritage, Education And Visitor Brands From Dublin Road
Rane Digital works from 65 to 69 Dublin Road, BT2 7HG, between Shaftesbury Square and the city centre, with a second office on Rathfriland Street in Banbridge. It also lists London and Dublin offices. The operating company, Rane Group Ltd, has been registered at Companies House since March 2017.
SEO is the first service Rane lists and part of what it calls its performance marketing specialism, alongside PPC. The team also covers web design, branding, social media, apps and hosting, and holds Google Partner and Bing Ads accreditations.
Rane’s client list is stronger than most agencies of its size in the city. It names Historic Royal Palaces, the Game of Thrones Studio Tour, Queen’s University Belfast, Stranmillis University College, Chadwicks Group and The Self Storage Centre among its top clients. Pricing is quote-based. It suits visitor attractions, education bodies and larger SMEs that want a single team for the website, SEO and paid search.
7. Gekkoshot — Web Design And SEO Studio At Catalyst In Titanic Quarter
Gekkoshot is based at Concourse 1, Catalyst, Queens Road, BT3 9DT, in the Titanic Quarter innovation campus. Gekkoshot Ltd was incorporated at Companies House in June 2018 at the Catalyst address, and the business trades through related Gekkoshot companies registered there.
The agency presents itself as web design and SEO experts, and SEO has equal billing with design on its site. The SEO work covers on-site changes and off-site work to build a site’s credibility with Google, alongside content, social media management and AI-powered automation for clients.
Its testimonials come from named local businesses, including Complete Mortgage Solutions, whose contact describes the site steadily climbing the Google rankings, and Fitness Equipment NI. Gekkoshot was shortlisted at the Irish eCommerce Awards 2026 for B2C eCommerce Website of the Year for its rebuild of Just Dandy, a Portadown gift brand.
Pricing is by quote, with a free consultation. Gekkoshot suits small businesses that need a new website and ongoing SEO from the same studio, and want an agency close enough to meet in person.
8. Vend Digital — Ecommerce SEO For Shopify Brands From The Ulster Bank Accelerator
Vend Digital works from the Ulster Bank Accelerator at 11 to 15 Donegall Square East, BT1, with a second base at The Chronicle Press in Coleraine. John Walker founded the business in 2022, and it is run as a husband and wife team with vetted partners brought in when needed. The agency states that it does not outsource its core work.
Vend focuses on ecommerce. Its ecommerce SEO service covers audits, ranking growth across product and content terms, and fully managed SEO on Shopify, WordPress and custom platforms. It is a Shopify Partner Agency and Google Partner, and also runs Meta ads and Klaviyo email.
The headline SEO case study is Dreams.ie, where technical SEO, on-page work and search-led content delivered a 55% year-on-year rise in ecommerce revenue and lifted site health from 28% to 98%. Other clients include Raceland Europe, Born & Bred, Two Stacks Irish Whiskey, Fidela Coffee Roasters and McConnell Shoes. It suits Shopify brands across Northern Ireland and the Republic that want direct access to the person doing the work.
9. Web Force NI — Local And Technical SEO For Trades And B2B Firms At Conway Mill
Web Force NI is based at Conway Mill, 5 to 7 Conway Street, BT13 2DE, the restored linen mill off the Falls Road. SEO is one of its four headline services, alongside web design, Google Ads and AI website assistants.
The SEO service is set out in plain terms. It covers local SEO for map listings and “near me” searches, technical fixes for speed, mobile, indexing, structure and schema, service and location pages for each area served, links and digital PR from local and industry sites, ecommerce category and product optimisation, and visibility in AI assistants. Monthly fees are set after a free SEO review, and the agency states openly that it does not guarantee number one rankings, which is a good sign.
Published case studies cover Atlas World, MTA Components, Skilled Contracts, Norspace Hire, Johnson Stevens NI and Transocean NI, which points to a client base of trades, industrial suppliers and B2B service firms. Web Force NI suits local trades and B2B firms in Belfast and the surrounding area that want a straightforward local SEO programme alongside a well-built site.
10. VINDICTA — SEO, Video And Google Ads From Meadow House On East Bridge Street
VINDICTA is based at Suite 213, Meadow House, 22 East Bridge Street, BT1 3NR, near the Lanyon Place end of the city centre. It describes its specialisms as SEO, web design, video production, Google Ads and social media, and lists SEO among its core services.
Its SEO work covers local SEO, wider national and global SEO, Google Business Profile optimisation and ecommerce SEO. In-house video production helps firms that want video content to support search and YouTube visibility.
Its terms are clear that SEO results, rankings and traffic levels are not guaranteed, and they set out payment structures in advance, including upfront payment for marketing services. The agency displays a Forbes Agency Council membership badge from 2021. Pricing is quote-based. VINDICTA suits small and mid-sized businesses that want SEO, video and paid search bought from one supplier.
How To Choose An SEO Agency In Belfast
Are They Actually Based In Belfast?
Many firms that rank for Belfast search terms work from Glasgow, Manchester or London and use a city landing page, sometimes with a virtual office address. Check the agency’s contact page for a full street address, then look the company up at Companies House to see where it is registered. Northern Ireland companies carry an NI prefix on their company number.
Do You Need A Specialist Or A Full-Service Agency?
A specialist SEO consultancy or a small team led by a senior practitioner usually gives you more senior time per pound, which matters for technical work, migrations and penalty recovery. A full-service agency makes sense when the website itself needs rebuilding or when SEO and paid search need to be managed together. Most of the agencies on this list are mixed shops, so ask what share of the team works on SEO full time, and whether the person who pitches is the person who does the work.
What Should SEO Cost In Belfast?
Belfast rates sit below London and broadly in line with other UK regional cities. As a typical market range, a local SEO retainer for a small business runs from about £350 to £1,000 a month, a regional or competitive campaign from about £1,000 to £2,500, and a national ecommerce or multi-market programme from £2,500 to £5,000 or more. One-off technical audits commonly cost £500 to £2,500. The published figures from Belfast agencies fit that pattern: Platform’s packages run from £350 to £1,000 a month, Vudu suggests £500 to £2,500 for local and regional work, and ProfileTree’s bands run from £1,000 to £3,500.
Can They Show Results With Named Clients?
Ask for case studies with a named client, a starting point, a time frame and a metric that matters to revenue, such as leads, enquiries or ecommerce revenue, not just traffic. Good examples on this list include Vend Digital’s Dreams.ie work and Loud Mouth Media’s SSE Airtricity figures.
How Long Before You See Results?
Technical fixes and Google Business Profile improvements can show results within weeks, but most campaigns need three to six months before rankings and leads move clearly, and competitive national terms can take a year. A sensible agency will set milestones at three, six and twelve months and offer an initial term of around six months rather than a long lock-in. Be wary of anyone who guarantees a number one ranking.
For larger brands that want SEO and paid media managed together, Loud Mouth Media is the strongest Belfast SEO agency on this list. SMEs that want published pricing and training should look at ProfileTree, while Codefixer suits firms that want a senior specialist working on the account. Platform Marketing Agency and Vudu Digital are the clearest options for small businesses on a set budget, Vend Digital is the pick for Shopify brands, and Rane Digital, Gekkoshot, Web Force NI and VINDICTA suit firms that want web design and SEO from one team, and each is an SEO company Belfast owners can meet in person.
Before you sign, run a quick checklist. Confirm the street address and the Companies House record. Ask who will do the work and how much of their time you get. Request two case studies with named clients and revenue-linked results. Get the monthly fee, the minimum term and the reporting schedule in writing. Finally, compare at least three proposals for SEO services in Belfast, and walk away from any agency that guarantees rankings.
