Google Analytics measures how websites and apps are used. GA4 is the current version, recording behavior as events.

Measuring how a site is used

Google Analytics measures and analyzes how websites and applications are used. The current standard is Google Analytics 4, or GA4. Beyond visit counts, it captures behavior — reading a page, pressing a button, completing a purchase.

What it tells you

  • Roughly how many people used the site or app
  • Where they arrived from: search, social, advertising
  • Which pages and content are read most
  • Whether people completed the actions you care about, such as signing up or buying

GA4 records behavior as events. Page views, clicks, and purchases are all events, which is what lets behavior across a website and an app be analyzed the same way.

Collecting numbers is not the point

What matters is choosing which numbers to look at from your purpose. For an article site, that might be which pieces are read and where people go next; for a shop, the path from viewing a product to buying. Do not conclude from a number rising or falling alone — compare periods and traffic sources and work out why.

What data arrives depends on your measurement setup and on consent settings, so the same site can produce different figures. GA4 numbers are a visible tendency within the conditions you configured, not a complete count of reality.

Combining it with AI

Exporting reports as CSV, or pulling them through the API or a tool like gogcli, lets an AI help organize trends and propose hypotheses. A correlation the AI finds is not a cause, though. Judge against what you actually did and what was happening at the time.

Analytics also requires care with privacy. Avoid sending personally identifying information, and operate within the law where you are, the consent rules that apply, and Google’s terms.
