How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A marketing analytics agency builds and maintains the measurement layer underneath a company's marketing: Google Analytics 4 and Tag Manager implementation, conversion and event tracking, consent-aware and server-side collection, attribution modelling, and the reporting that turns all of it into a number an owner can act on.
Fourteen Belfast agencies passed our evidence check, judged on what their own sites say about analytics, tracking, tag management or attribution. Twelve publish a Belfast address; Atlanticus Digital and Rane Digital Marketing Agency work the city from Banbridge. Six name clients, an unusually high share for this series, and none of them publishes a rate we could verify on its own site.
Which Belfast marketing analytics agencies name their clients?
Six of the fourteen external agencies here name a client on their own site, from Queen's University Belfast at Search Scientist to Stage Entertainment at GlowMetrics. Twelve of the fourteen publish a Belfast address, and none publishes a verifiable rate.

Frequently Asked Questions
Which Belfast firms publish client names?
Six of the fourteen. GlowMetrics credits Stage Entertainment and the Good Law Project, Search Scientist credits Queen's University Belfast, Made To Engage credits New Era Cap, Loud Mouth Media credits SSE Airtricity, YouFibre and Lyle & Scott, Glaze Digital credits Gordons Chemist, and Digital 24 credits Dale Farm. Ask each whether the engagement included measurement work or only the campaign that sat on top of it.
Our traffic spans two jurisdictions. How should that be tracked?
As separate markets from the start. Google Analytics runs on 47.6% of all websites, so almost every engagement starts inside an account somebody else configured years ago. A single property that pools Northern Ireland, the Republic and Great Britain will average away the differences in currency, delivery and consent behaviour that decide your margin. Ask how each firm segments the property by market, whether the consent banner behaves differently by jurisdiction, and how revenue is reported in the currency each market actually pays in.
We inherited a Tag Manager container nobody documented. Where does an agency start?
Google Tag Manager sits on 45.5% of all websites and holds 99.6% of the tag manager market, which is why most audits begin in a container nobody has documented. The first useful deliverable is not a dashboard, it is an inventory: every tag, trigger and variable in the container, what each one fires on, and which are dead. Ask to see that inventory as a document before any new tracking is added, and ask who is allowed to publish container versions once the work starts.
What does analytics work cost in Belfast?
None of the fourteen publishes a rate we could verify on its own site, so build your own anchor. Ask each shortlisted firm to price three separate lines against one identical brief: the audit of what exists, the implementation to fix it, and the ongoing reporting and analysis. Most proposals collapse all three into one monthly retainer, which hides how much of the fee is one-off build work.
Most of these agencies sell PPC or SEO first. Does that disqualify them?
No, but it changes the questions. An agency measuring its own campaigns has an obvious incentive in how conversions are counted, which is manageable if the tracking plan is written down and the raw data stays in your accounts. Ask whether you own the GA4 property, the container and the ad accounts, and whether the reporting shows platform-claimed conversions beside what your own systems recorded.
Choosing a Marketing Analytics Agency in Belfast
Six of fourteen name a client. That is a strong disclosure rate for this series, and Queen's University Belfast, Stage Entertainment and SSE Airtricity are references you can approach directly rather than screenshots you have to trust.
Twelve publish a Belfast address. Atlanticus Digital and Rane Digital Marketing Agency both answer from Banbridge, which we have named rather than listing them as local firms.
Separate the markets before reading a single rate. Northern Ireland, the Republic and Great Britain behave differently on currency, delivery and consent, and a pooled property will hide all three differences.
Nobody publishes a verifiable rate. Price the audit, the implementation and the ongoing analysis as three lines against one brief, and keep the property, the container and the ad accounts in your own name. If you would rather have the measurement, the paid search and the growth programme reporting to one number, read our latest analysis or see how we work in Belfast.
