What is Analytics?
Analytics, as an agency specialism, covers the setup and ongoing management of the tools that measure what your marketing and website are actually doing. That means configuring GA4 properly (not just the default install, which misses most useful events), setting up Google Tag Manager or a server-side tagging solution, building conversion tracking that actually matches what the business counts as a sale or lead, and creating dashboards (often in Looker Studio or Power BI) that pull data together in one place. More advanced work includes attribution modelling - working out which touchpoints actually deserve credit for a conversion - and data layer work for e-commerce sites so revenue, product and customer data all connect properly. This sits underneath every other channel: SEO, PPC and social agencies all rely on this tracking being accurate, which is exactly why it's often outsourced to a specialist rather than left to whichever channel agency happens to touch it last.
Why Hire a Analytics Agency?
- Fixes broken or incomplete GA4 tracking, a very common issue since the migration from Universal Analytics
- Builds conversion tracking that matches actual business definitions of a sale or lead, not platform defaults
- Sets up server-side tagging to improve data accuracy as browsers restrict third-party cookies
- Creates centralised dashboards so stakeholders aren't pulling contradictory numbers from different platforms
- Builds attribution models that show true channel contribution instead of last-click bias toward paid search
- Provides independent measurement that isn't influenced by whichever agency is trying to prove its own channel worked
Frequently Asked Questions
How much does an analytics setup cost in the UK?
A proper GA4 and Tag Manager setup with conversion tracking typically costs £1,500-£5,000 as a one-off project, depending on site complexity and the number of conversion events. Ongoing dashboard maintenance and reporting retainers usually run £500-£2,000 a month. Server-side tagging and attribution modelling projects are more involved and commonly start from £5,000.
How do I choose an analytics agency rather than asking my existing agency to handle tracking?
If your SEO or PPC agency set up your tracking, there's an inherent conflict of interest in them also reporting on how well their own channel performed. An independent analytics specialist gives a more objective read on channel performance and is worth it if you're running multiple agencies and need a neutral referee for where budget is actually working. For a single-channel setup with one trusted agency, it's often fine to leave tracking with them.
How long does an analytics and tracking project take?
A standard GA4 and conversion tracking setup takes 2-4 weeks including testing. Attribution modelling projects, which require enough historical data to build a reliable model, typically take 6-8 weeks and are more valuable for businesses with meaningful traffic volume - the models need data to learn from.
What's the most common mistake businesses make with analytics?
Treating GA4's default setup as sufficient. Out of the box it captures generic engagement events but rarely tracks the specific conversions that matter to a business - form completions, phone clicks, add-to-basket, checkout steps. Many businesses only discover this months later when they try to report on ROI and realise the underlying data was never being captured properly.
