Google Analytics: What It Is and the Best Alternatives in 2026

Google Analytics is a free web analytics platform by Google that tracks website visitors, their behaviour, and traffic sources. GA4 is the fourth and current version, which replaced Universal Analytics in July 2023. This guide covers everything you need to know about Google Analytics 4 and the 6 best alternatives for European businesses.

What Is Google Analytics

Google Analytics (GA4) is Google’s free web analytics platform that tracks and reports on traffic to websites and mobile apps. It provides detailed data on:

1. Audience — who visits your site (demographics, devices, geography)
2. Behaviour — which pages they view, time on site, what they click
3. Acquisition — where visitors come from (search, social, ads, direct)
4. Conversions — what actions they take (purchases, form fills, calls)

Google Analytics 4 (GA4) is the fourth generation of the platform, launched by Google in 2020. From 1 July 2023, the old version (Universal Analytics) stopped collecting data, making GA4 the only current solution from Google.

Key Features of Google Analytics 4

Event-based data model

Unlike Universal Analytics, GA4 uses an event-based model. Every user action — page view, click, scroll, form submission — is recorded as an event with its own parameters. This provides much more flexible analysis options.

Cross-platform analytics

GA4 unifies data from your website, iOS app, and Android app in a single report. You can see the complete user journey — for example, someone who discovered your brand via desktop search and later purchased through a mobile app.

Traffic channels in GA4

One of GA4’s most important features is the Traffic Acquisition report, which shows where your visitors come from. GA4 automatically groups traffic into channels:

1. Organic Search — free search traffic (Google, Bing, DuckDuckGo etc.)
2. Direct — direct visits (typed URL, bookmarks, some email clicks)
3. Paid Search — paid search advertising (Google Ads, Microsoft Ads)
4. Organic Social — unpaid social media posts (Facebook, Instagram, LinkedIn)
5. Referral — clicks from other websites
6. Email — clicks from email campaigns (with UTM parameters)
7. Paid Shopping — Google Shopping ads
8. Paid Social — paid social advertising (Meta Ads, TikTok Ads)

To accurately track traffic sources, we recommend using UTM parameters in all marketing campaigns. This allows you to see the exact source of each visit in the Source / Medium column.

Machine learning and predictive analytics

Google Analytics 4 includes built-in AI capabilities: predictive analytics (purchase probability, churn probability), anomaly detection, and conversion modelling that fills gaps caused by ad blockers and iOS restrictions.

BigQuery integration

GA4 (even the free version) allows free raw data export to Google BigQuery. This opens up possibilities for complex SQL analysis, custom dashboards in Looker Studio, and unlimited data storage without sampling.

Is Google Analytics Free?

Google Analytics 4 is free for the vast majority of websites. The standard GA4 includes:

1. Up to 10 million events per month
2. 14 months of data retention (configurable to 2, 6 or 14 months)
3. Unlimited properties and data streams
4. Free BigQuery Export
5. All core reporting features

The paid Google Analytics 360 (from $150,000/year) is aimed at large enterprises and provides higher limits, SLA guarantees, and unlimited sampling.

GA4 Pros and Cons

Advantages of GA4

1. Free — full-featured analytics at no cost
2. Google ecosystem integration — Google Ads, Search Console, Merchant Center, Looker Studio
3. Cross-platform analytics — web + mobile in one place
4. BigQuery Export — access to raw data for deep analysis
5. AI features — predictive analytics, automatic insights

Disadvantages of GA4

2. Complex interface — steep learning curve, especially for Universal Analytics users
3. Data sampling — free version may sample data at high traffic volumes
4. Limited retention — maximum 14 months without BigQuery
5. Data sharing with Google — your user data contributes to Google’s data ecosystem

Comparison: GA4 vs Alternatives

Which Should You Choose: GA4 or an Alternative?

1. Most businesses → Google Analytics 4 (free, most data, Google Ads integration)
2. Privacy-critical companies → Matomo (self-hosted) or Plausible
3. SaaS and product companies → Mixpanel or Amplitude (alongside GA4)
4. UX and behaviour analysis → Microsoft Clarity (free, alongside GA4)
5. Small businesses without tech teams → Plausible or Fathom

For most European businesses, the optimal combination is Google Analytics 4 + Microsoft Clarity. GA4 provides quantitative traffic and conversion analytics; Clarity provides qualitative behaviour insights. Both are free.

Frequently Asked Questions

Is Google Analytics GDPR compliant?

GA4 can be used in a GDPR-compliant way with Consent Mode v2 — a consent banner that allows or blocks data transmission to GA4 based on user choice. Without proper Consent Mode implementation, GA4 may violate GDPR regulations in the EU.

How long does GA4 store data?

By default — 2 months for user-level data, 14 months for aggregated reports. Maximum retention for user data is 14 months. For long-term storage, use the BigQuery Export feature.

What is the difference between GA4 and Universal Analytics?

Key differences: GA4 uses an event-based model (not session/hit-based), supports cross-platform analytics, includes free BigQuery Export, uses machine learning, and has a completely redesigned reporting interface.

Conclusion

Google Analytics 4 is the most powerful free web analytics tool on the market. For most European businesses, GA4 remains the first choice — especially for those already using Google Ads, Search Console, or the broader Google ecosystem.

If data privacy is critical, or you need deep product analytics, consider Matomo (self-hosted), Plausible (simplicity), or Mixpanel/Amplitude. These tools can complement GA4 rather than replace it.
