Comparative review of web analytics systems for custom websites and e-commerce

Title Banner Image

In modern digital business, data decides everything. Without analytics, a company loses control over key processes: marketing, user behavior, sales funnels, and the efficiency of acquisition channels. Numbers reveal which campaigns bring profit, where users get “stuck” in the interface, and which customer segments deliver the most value. For this, companies increasingly use end-to-end website analytics, which combines metrics about traffic, sales, and customer interactions into a single picture.

Many companies by habit use Google Analytics as their main tool for evaluating traffic and user behavior. However, in recent years the question arises more often: is it enough? GA has its limitations – from complex setup to controversial GDPR issues and report latency. For custom solutions and online stores, this may not be sufficient: businesses need flexible reports, control over user scenarios, and transparency in working with data.

In this article, we will look at alternative web analytics systems that are suitable for custom websites and e-commerce platforms. We will compare their functionality, approaches to processing metrics, and cost to help choose the optimal tool for specific business needs.

Website analytics: main requirements for custom solutions

For website analytics to truly help the business, it is important to consider not only basic traffic collection but also the specific tasks of custom websites and online stores. The key requirements include:

  • GDPR support and confidentiality.
    More and more companies face requirements from regulators and clients regarding personal data protection. An analytics system must guarantee anonymization, storage, and processing of information in accordance with European and local standards.
  • Easy integration with CMS, e-commerce, and custom projects.
    Universal solutions do not always work “out of the box” for complex systems. It is important that website analytics can be quickly embedded into WordPress, Django, Laravel, Shopify, or custom-built platforms.
  • Metrics required for online stores.
    In addition to standard traffic indicators, businesses need conversions, sales funnels, order sources, and average order value. These analytics directly influence understanding of marketing effectiveness and product profitability.
  • Convenience for marketing and IT teams.
    Marketers need visual reports and understandable metrics for decision-making. IT specialists value API, extensibility, and fine-tuning capabilities. A good system should equally satisfy both sides.

Google Analytics (GA4) – the most popular online website analytics

Google Analytics remains the most widespread solution for web analytics, and for many companies it becomes the first entry point. The new GA4 version moved from the classic session-based model to an event-based model, which allows flexible tracking of user actions. However, with the update, the service became significantly more complex to configure and raised questions from businesses, especially related to GDPR and data storage.

To understand the strengths and weaknesses of GA4, let’s look at its key characteristics in a table:

Characteristic Description
Data model Event-based model instead of sessions
Cross-platform Tracking web and mobile apps in a single system
Integration Connection with Google Ads, BigQuery, Search Console
Data storage Free plan: up to 2 months by default (up to 14 months with configuration); paid GA360 – more
Cost Free, GA360 – Enterprise custom terms
Reporting Flexible dashboards and event setup, but complex interface
Speed Delays exist, not all in real time
Confidentiality Data stored in the US, possible compliance concerns

 

Pros:

  • Free plan with wide capabilities
  • Integration with Google advertising services
  • Universal event-based model

Its main distinction is maximum flexibility: Matomo can be deployed on your own server (self-hosted) or used in a cloud version. The service complies with GDPR, provides security control, and offers extended capabilities for e-commerce and custom solutions.

Matomo suits both online stores and corporate websites: it includes advanced reports on funnels, click maps, heatmaps, and user segmentation. This makes it more powerful than Plausible or Umami, but also more complex to administer.

Conclusion

The choice of analytics system depends on the scale of the business and its priorities:

  • Google Analytics (GA4) remains the default standard, but it is complex to configure and raises privacy concerns. It is convenient for companies that actively use the Google ecosystem and are ready to accept its limitations.
  • Plausible Analytics is the optimal choice for small and medium businesses, startups, and custom solutions, where simplicity, compliance with European regulations, and transparency are crucial. Our team often recommends Plausible to clients who need straightforward website traffic analytics without unnecessary complexity.
  • Umami Analytics is best for those who want a free and fully self-hosted solution. It is an excellent option for companies that value control over statistics but are ready to maintain the system on their own.
  • Matomo Analytics is more enterprise and e-commerce oriented: it is a powerful GA alternative with advanced reports, heatmaps, and sales funnels. Suitable for large online stores and corporate websites.
  • Ahrefs Web Analytics is a niche tool, strong for SEO-focused projects and content-driven businesses. It combines web analytics with SEO but still lags behind classic systems in flexibility.
