Decision help

What we recommend, and when.

Google Analytics 4 (GA4), if …

Google Ads is a major budget line and conversion import is mandatory.

The team already works in the Google stack, from GTM to BigQuery.

Budget for analytics licences simply does not exist.

Piwik PRO, if …

Hosting must sit in the EU by contract, with DPA and audit logs.

Regulated industry: MedTech, finance, or the public sector.

Analytics must measure cleanly without consent, in anonymous mode.

Scenario
Recommendation
Why
Performance marketing with Google Ads as the core channel
GA4
Native conversion import and audiences that Piwik PRO does not connect.
MedTech, finance, or public sector
Piwik PRO
EU hosting with DPA plus a documented anonymous mode.
Warehouse-centric reporting in BigQuery
GA4
The native BigQuery export is free and stable.
Transition phase, consent strategy still open
Both in parallel
GTM Server-Side feeds both from one event stream.

Our verdict

Performance marketing on Google Ads favours GA4. Regulated industries and mandatory EU hosting favour Piwik PRO. The consent question decides the rest.

In depth

What this comparison covers

GA4 and Piwik PRO compete in the same projects: web analytics for marketing teams in DACH. The difference is not the feature set; it is hosting, consent behaviour, and the ads connection.

The criteria table above comes from our editorial scores; the per-tool breakdowns live on the two tool pages. Teams setting up today rarely decide tool against tool but stack against stack: GA4 pulls BigQuery and Google Ads along, Piwik PRO brings its own CMP and tag manager.

The GDPR analytics comparison places both tools against Plausible CE, Matomo and etracker.

Privacy and EU fit

GA4 processes data in the US cloud; Consent Mode models the gaps instead of measuring them. Piwik PRO guarantees the EU region by contract and measures without consent in anonymous mode. In any pure privacy assessment the point goes to Piwik PRO.

Implementation effort

A standard GA4 setup via GTM stands in a few days; the conventions are established across the market. Piwik PRO needs more planning on the event schema and brings tag manager and CMP along in return. Both setups run through GTM Server-Side at our end.

Pricing and TCO

GA4 costs no licence but a steady stream of consent repairs and data-quality work; GA360 starts far higher as an enterprise licence. Piwik PRO starts as a Business subscription from €36/month and scales by traffic; the former free tier is gone, replaced by a 30-day trial. Honest maths: in consent-critical setups the Piwik PRO licence is often cheaper than the GA4 workarounds.

Migration

4 to 6 weeks for a standard setup: two weeks of event-schema mapping, two weeks of implementation in parallel with GA4, one to two weeks of validation against the GA4 numbers. We recommend at least four weeks of parallel running before GA4 is switched off.

Yes. Via GTM Server-Side both run from one event stream. A four-week parallel run is our standard before any migration.

GA4 history cannot be imported into Piwik PRO. The BigQuery export preserves the raw data for later analysis, which is why we switch it on before any shutdown.

Not anymore. The former free tier gave way to a 30-day trial; entry is the Business plan from €36/month. Enterprise features such as SSO, audit logs, and longer retention sit in the Enterprise plans from €366/month.

What neither of them fixes

No analytics tool repairs a missing tracking concept.
