Frequently Asked Questions About Google Analytics
1. Is Google Analytics free to use?
Yes, the standard version of Google Analytics (GA4) is free to use with no limitations on the number of websites you can track. There is also Google Analytics 360, which is a premium version that offers additional features like higher data processing limits, more custom dimensions, and dedicated support. However, for most small to medium-sized businesses, the free version provides more than enough capabilities.
2. How long does Google Analytics keep my data?
In GA4, the default data retention period is set to 14 months, but you can adjust this in your property settings. You can choose between 2 months, 14 months, 26 months, 38 months, or 50 months. It's worth noting that this setting only affects certain user-level and event-level data; aggregated data in standard reports is kept indefinitely regardless of your retention settings.
3. Can Google Analytics track mobile apps as well as websites?
Without question, the architecture of GA4 revolutionizes multi-platform measurement. The system enables seamless data integration from your website, Android applications, and iOS interfaces—all consolidated within a single property. This cohesive approach delivers an uninterrupted view of how visitors engage across various touchpoints and devices, empowering marketers to construct a more detailed understanding of the complete customer experience.
4. How accurate is Google Analytics data?
While Google Analytics is generally reliable, several factors can affect its accuracy:
- Ad blockers and privacy extensions can prevent tracking
- Users who disable JavaScript won't be tracked
- Some sophisticated bots might not be filtered properly
- Sampling may occur with large volumes of data
To improve accuracy, regularly audit your implementation, use filters to exclude internal traffic, enable enhanced measurement features, and consider implementing server-side tracking where appropriate.
5. How do I share Google Analytics data with my team or clients?
Google Analytics offers several ways to share data:
- Add users directly to your GA account with appropriate access levels
- Create and schedule email reports to be sent automatically
- Export data to Google Sheets, Excel, or CSV formats
- Build custom dashboards in Google Data Studio (now called Looker Studio) for more visual reporting
- Use the Google Analytics API to pull data into custom applications or reporting tools
