30 agencies are listed in Belfast, 1% of the 3,907 recorded in United Kingdom — the country's 13th city by agency count. 28 publish a direct contact.
In Belfast: SEO (100%), Web Design (63%), Social Media (53%), Web Development (43%), SEA/PPC (37%). An agency that ticks every box is rarely good at all of them: look at what it puts first.
Proximity genuinely matters in two cases: local SEO — Google Business profile, reviews, "near me" queries — and needing to meet in person. For an e-commerce or SaaS site targeting the whole country, an agency in Belfast holds no structural advantage over one elsewhere in United Kingdom. The useful criterion stays experience with your type of site.
| Team size | Belfast | Typically |
|---|---|---|
| 1-10 | 29 (97%) | Solo consultant or small studio. Direct access, limited capacity. |
| 11-50 | 1 (3%) | Separate roles: technical, content, link building. |
The 30 agencies on this page are ordered by how complete their listing is, never by payment: no position is for sale here. The information is collected from each agency's own website, checked as live. An agency can claim its listing to correct it, complete it, or connect its Search Console data.
What does SEO cost in Belfast? Stated engagement floors here start at $1,000+. That figure says what size of engagement the agency takes on, not what yours will cost: the quote depends on the state of the site, the competition and the volume of content to produce.
Small local agency or large firm? 97% of agencies in Belfast have fewer than ten people. At that size you talk directly to whoever does the work — the main advantage, and the main limit the day the engagement grows.
How do you check an agency before signing? Ask for a measured case on a site comparable to yours, with before and after figures. Check who will actually do the work. And get it in writing what stays yours when the contract ends: content, access, accounts.
