In short

What does a senior digital analytics agency do?

A digital analytics agency designs and operates your analytics stack: GA4 + GTM server-side + BigQuery as data warehouse + Looker Studio for dashboards. It covers 6 disciplines: tracking implementation, multi-touch attribution, executive reporting, experimentation (A/B + CRO), data engineering and GDPR compliance. It kills the false "direct" channel, recovers attribution lost to iOS 17, and connects marketing to real revenue.

Cronuts.digital has been operating analytics in B2B, SaaS and DTC ecommerce for 8 years. Official stack: GA4 + GTM server-side (Stape/Cloudflare) + BigQuery + Looker + optional Segment. Retainer from €2,500/month (1 analyst + dashboards + reporting), one-shot audit from €3,800.

iOS 17 hides 46% of your sales in your dashboards. Without a serious analytics agency running server-side tracking, you make decisions on fake data.

What it includes · digital analytics agency

Six disciplines of a senior analytics agency.

Discipline 2 · attribution

Analytics truths 2026

Six things your previous analytics agency didn't tell you.

iOS 17 + ITP + adblockers hide 40-60% of sales client-side. Server-side is mandatory.

"Direct" in GA4 is an 80% lie. It's traffic misattributed due to broken tracking.

Dashboards with 30 KPIs are useless. A CMO needs 5 numbers: revenue, MER, CAC, LTV, pipeline.

Google Analytics with sampling = decisions on partial data. BigQuery raw data is mandatory.

Zapier with personal data without a DPA violates GDPR. Fines up to 4% of global turnover.

Last-click attribution is invalid in B2B. Multi-touch or don't bother reporting.

Frequently asked questions

What CMOs and RevOps ask us about digital analytics.

How much does a retainer with an analytics agency cost?

Ranges: one-shot audit €3,800-6,500 (executive doc + gap analysis + roadmap, 2-3 weeks). Analytics retainer €2,500/month (1 analyst + dashboards + monthly reporting, min 6 months). Premium retainer €5,200/month (squad: analyst + data engineer + A/B specialist). Initial implementation billed separately (€3,200-9,500 depending on stack).

What stack do you recommend?

Standard stack: GA4 (tracking) + GTM server-side via Stape.io (cookieless) + BigQuery (data warehouse) + Looker Studio (dashboards). Optional extras: Segment / RudderStack (CDP), GrowthBook (A/B), Cookiebot (consent). Zero proprietary SaaS, zero lock-in. Open standards.

Why is server-side tracking mandatory?

iOS 17 + ITP 2.3 + Safari + adblockers block or limit 40-60% of client-side events. GTM server-side (Stape, Cloudflare Workers) sends events from your server, not the browser. Cookieless, first-party, resilient to browser updates. Serious standard since 2023.

Do you work on our existing GA4 or set up a new one?

It depends on its state. If your GA4 is properly implemented, we audit it, optimize it and add server-side + BigQuery on top. If it's broken (events without schema, incorrect attribution, data silos), we recommend reimplementing in 2-3 weeks. The initial audit defines the path.

How much does BigQuery + Looker cost?

Your own costs (not part of the retainer): BigQuery typically €80-230/month for mid-size ecommerce / B2B (< 100 GB). Looker Studio free with native connectors, Looker Pro €24/user/month if you need advanced scheduled sends. We optimize queries to keep costs under control.

How do you migrate from Google Analytics Universal?

GA Universal sunset was July 2023, historical data still accessible until July 2024. If you haven't migrated: GA4 implementation + historical BigQuery export (preserve 2+ years of data) + backfilled dashboards in Looker. 3-4 week project.

Do you integrate with HubSpot, Salesforce, Pipedrive?

Yes. We connect your CRM (HubSpot, Salesforce, Pipedrive, Holded) with BigQuery for a unified data warehouse. Automated daily pipeline. See CRM integration for webhook + attribution architecture details.

How does it connect with CRO and A/B testing?

The analytics stack is the foundation for CRO. With GA4 + GTM server + BigQuery, GrowthBook A/B tests use real server-side data (not vanity). See CRO. Analytics + CRO retainer bundle: -10%.
