What is Web Analytics? Definition, Metrics, and Why It Matters
Web analytics is the collection and analysis of data about website traffic, visitor behavior, acquisition sources, conversions, performance, and user journeys. It helps teams understand what happens on a website and how that activity supports business goals.
At its simplest, web analytics answers questions such as: How many people visited? Where did they come from? Which pages did they view? Did they convert? Did the website perform well?
Core web analytics metrics
Common web analytics metrics include:
- Page views
- Unique visitors
- Sessions
- Bounce rate
- Time on page
- Average session duration
- Traffic channels
- Referrers
- Conversion rate
- Custom events
- Funnel completion
- Revenue
No single metric tells the full story. Traffic volume, behavior, conversion, and technical quality should be analyzed together.

Teams use web analytics to:
- Measure marketing campaigns
- Improve landing pages
- Understand content performance
