If your website simply “exists” without proper analytics, you are running your marketing blind. For business owners in the Czech Republic and across the EU — where the cost per click in Google Ads and Meta Ads keeps rising — accurate data becomes a major competitive advantage.
Key advantages of GA4:- Event-based tracking: Every action (click, scroll, video view) is an event, giving deeper insights into complex multi-page websites.
- Cross-device analytics: Track the same user across desktop and mobile.
- Predictive metrics: AI forecasts purchase probability and churn risk.
- Privacy-first: Improved Cookie Consent Mode — critical for EU compliance.
Основные отличия GA4:Событийная модель (Event-based): Любое действие (клик, скролл, просмотр видео) — это событие. Это позволяет глубже анализировать
многостраничные сайты со сложной структурой.
- Сквозная аналитика: Возможность отслеживать одного и того же пользователя на разных устройствах.
- Прогнозная аналитика: ИИ предсказывает вероятность покупки или ухода клиента.
- Конфиденциальность: Улучшенная работа с Cookie Consent (режим согласия), что критично для соблюдения законов ЕС.
1. Create a Property and Data StreamStart by creating a Google Analytics account and a GA4 property. For your website, set up a Web Data Stream — this will generate a unique Measurement ID (G-XXXXXXXXXX).
2. Install the Tracking CodeThere are two main installation methods:
Directly in your code: Add the gtag.js script to the <head> section. Good for simple
one-page sites.
Via Google Tag Manager (GTM): Recommended. Allows you to manage all tags (Analytics, Facebook Pixel, Hotjar) without developer involvement.
3. Configure Key Events (formerly Goals)GA4 no longer uses “goals.” Instead, you mark important events as
Key Events, such as:
- Form submissions
- Clicks on phone numbers or email links
- Add-to-cart actions (for e-commerce)
- Visits to a “Thank You” page
Many business owners in the Czech Republic try to configure analytics using generic online tutorials. But European regulations and GA4’s technical nuances often lead to critical data issues. Here are the most common pitfalls:
Duplicate tags and “noise” in reports
Installing GA4 both via a CMS plugin and manually leads to double tracking, inflated traffic, and misleading analytics.
Ignoring internal traffic
If you don’t filter out your own IP addresses (or your team’s), your numbers for bounce rate and conversions become inaccurate — especially during the early stages of a project.
Incorrect Consent Mode v2 setup
In the EU, data collection is strictly regulated. If GA4 collects data inconsistent with a user’s cookie-banner choice, you risk violating GDPR or having your Google Ads account restricted.
A proper setup allows Google’s AI to model data even when cookies are declined — legally and safely.
Missing cross-domain tracking
If your user journey spans multiple domains (e.g., main site + booking platform), GA4 may treat the same user as two separate visits, breaking your sales funnel.
Missing referral exclusions
When customers pay via Czech payment gateways (e.g., GoPay, ComGate), they briefly leave your site.
Without exclusions, GA4 attributes the sale to the payment gateway — not the real marketing source.
When building
template-based or fully custom websites, we follow a
Data-First analytics approach:
Clean, reliable dataWe always exclude internal traffic and block spam bots.
Full event auditWe don’t “just add the code.” We configure meaningful events for every important user action — from messenger clicks to scroll depth.
Integration with Google AdsWe import GA4 conversions directly into Google Ads, allowing Google’s algorithms to optimize for cheaper and higher-quality leads.
Full EU complianceWe set up proper Consent Mode v2, ensuring accurate data collection based on each user’s cookie preferences.
Incorrect data is worse than having no data at all. If you suspect your GA4 is not set up properly or you notice mismatches between orders and reports — we can fix that.
