What is Web Analytics?

Web analytics is the collection, measurement, and analysis of website data to understand visitor behavior, optimize user experience, and improve business outcomes.

Web Analytics explained

Web analytics tools track what happens on your website: how many people visit, which pages they view, where they come from, what devices they use, and how long they stay. This data helps you make informed decisions about content, design, marketing, and product development.

Core metrics include pageviews, unique visitors, sessions, bounce rate, session duration, and traffic sources. More advanced analytics cover conversion tracking, user flows, cohort analysis, and revenue attribution. Modern tools range from simple page counters to full product analytics suites.

The field has evolved significantly. Early web analytics focused on server logs and hit counters. Today's tools use JavaScript tracking, first-party cookies, and server-side events to build a detailed picture of user behavior while navigating increasing privacy expectations and regulations like GDPR.

Examples

  • Checking your analytics dashboard to see that a blog post published yesterday brought 2,000 new visitors, mostly from organic search.
  • Analyzing traffic sources to discover that 40% of your visitors come from a single Reddit thread, suggesting community engagement is working.
  • Comparing week-over-week unique visitors after a site redesign to see whether the changes improved or hurt engagement.
