How does GA4 differ from Universal Analytics?
"What are the main differences between Google Analytics 4 (GA4) and Universal Analytics? How do the changes in data models, reporting, and privacy features impact how businesses use GA4?"
GA4 fundamentally differs from Universal Analytics in several ways:
- Data Model: GA4 uses an event-based model where every user interaction is tracked as an event, unlike UA’s session-based model.
- Cross-Platform Tracking: GA4 allows for seamless tracking across both web and mobile apps within a single property.
- Privacy Features: GA4 offers enhanced privacy controls, such as cookieless tracking, customizable data retention policies, and consent mode to align with global privacy laws.
- Machine Learning Insights: GA4 uses predictive analytics to provide actionable insights, such as purchase probability and churn likelihood. These differences make GA4 more future-proof and capable of handling evolving privacy requirements and complex user journeys.

Dec 30, 2024Environment - is a set of necessary elements of technical / software infrastructure, which is the basis for the operation of a given website/application. Google Tag Manager environments are simply multiple versions of the same container. When we have a website with a different version for development, testing, production and QA, instead of creating separate GTM containers for each version, we can set up separate environments in the same container that will work independently in each version.

Dec 04, 2022If you plan email marketing campaigns you are interested in the same as with other campaigns, to measure their impact on your business. When you are starting with this topic it is good to know that without additional effort you will not be able to access this impact. You will see no results because Google Analytics will treat traffic from the email campaigns as direct traffic (when users are using your own app) or as referrals (when users are using web email clients).

What steps did customers take before downloading the file or purchasing the item? When a customer conversion occurs, it is rarely the customer's first interaction with your website or brand.
