What Google Analytics 4 (GA4) means
GA4 replaced Universal Analytics, which stopped processing data in 2023. It tracks how people find and use your site and which actions count as key events. It needs deliberate setup to measure what matters to your business, not just page views.
Why it matters for your website
GA4 shows where visitors come from and what they do, which tells you which marketing efforts bring leads. Without it set up well, you are guessing about your website's value. It is free, but the defaults rarely track what matters to your business without some setup.
Example
A Schaumburg law firm sets up GA4 key events for form submissions and phone clicks, then sees that most new cases start from its local service pages.
Tips
- Mark lead forms, calls and purchases as key events.
- Extend the data retention setting so you can explore older data.
- Link GA4 with Search Console and Google Ads for fuller reports.
Common mistakes
- Installing GA4 and never setting up key events beyond page views.
- Not filtering out internal traffic, so your own team's visits skew results.
