What it is
A session is one visit to your website — everything a single user does from arriving to leaving counts as one session, regardless of how many pages they view. A pageview is counted every time any page on your site loads. One session can include multiple pageviews.
Why it matters
Understanding the difference keeps you from misreading your analytics. Sessions tell you how many people visited. Pageviews tell you how much content they consumed. A high pageviews-per-session number often means visitors are engaged and exploring. A low number might mean they arrived, didn't find what they wanted, and left.
The mistake most people make
Reporting "we got 10,000 pageviews" as if pageviews equals traffic. Pageviews can be inflated by a small number of highly engaged visitors clicking through many pages, or by bots. Sessions give you a cleaner picture of actual visitor volume. Use both together to understand the full story.
