TL;DR

  • SME stack: Pirsch + server-side GTM + first-party email — roughly EUR 50-100 per month
  • Consent Mode v2 with default "denied" reduces ad-conversion loss from 30 percent to 5-10 percent
  • Cookieless analytics (Pirsch, Plausible) require no consent banner and remove TDDDG Section 25 friction
  • Contextual targeting sidesteps personal-data tracking entirely
  • First-party CDP consolidates owned data and replaces third-party tracking dependencies

1. Pirsch and Plausible (cookieless analytics)

Server-side, cookie-free analytics. Both are GDPR-compliant out of the box. Pirsch is German-hosted, Plausible is EU-based. Around EUR 30 per month for typical SME traffic. No consent banner required because no personal data is processed.

2. Server-side tracking via Google Tag Manager

Server-side GTM moves data collection from the browser to your server. This bypasses ad blockers, gives full control of which data leaves your domain, and keeps third-party scripts out of the user's browser. Implementation cost: 5-15 person-days plus a small server.

3. First-party customer data platform (CDP)

A first-party CDP (Segment, RudderStack as open-source alternative) consolidates owned data from website, email and product. Replaces third-party tracking with controllable, contracted processing.

4. Contextual targeting

Place ads based on the content of the page, not the identity of the viewer. No personal data, no tracking, no consent required. Particularly effective for B2B and content-led inventory.

5. Google Consent Mode v2

Default "denied" plus full data when consent is granted. Without consent, modeled and aggregated data still flows. The result: GDPR-compliant attribution that loses only 5-10 percent of conversion data instead of the 30 percent you lose with naive blocking.

Summary

The end of third-party cookies and tighter GDPR enforcement push marketers toward consent-friendly architectures. The cheapest stack for an SME is Pirsch plus server-side GTM plus first-party email at EUR 50-100 per month. Bigger marketing teams add Consent Mode v2 and a CDP. None of these strategies requires legal compromise.
