Session

A session is a single visit to a website or app, representing a continuous period of user activity. It begins when a visitor arrives and ends after a period of inactivity or when they leave. One session is typically counted in 30 minute increments. Common synonyms include: visits, site sessions, and browsing sessions.

Why Sessions Matter

Sessions help teams understand how customers engage with the experience. They reveal:

  • How many opportunities the site has to convert
  • How users move through the journey
  • Where friction or drop‑off occurs
  • How behaviour differs by device, channel, or audience

How Sessions Are Measured

Sessions are typically tracked through analytics platforms and defined by:

  • Session start: when a user lands on the site
  • Session end: after a period of inactivity (often 30 minutes) or when the browser closes
  • Session count: total number of sessions in a given period
  • Session attributes: device, channel, geography, landing page
  • Session behaviour: pages viewed, time on site, actions taken

Example: If a user visits the site, browses three product pages, adds an item to their cart, and leaves that entire journey counts as one session. If the user visits the site, browses three product pages, does nothing on that website for 30 minutes – and does not close the browser window – and then comes back to look at another product page and add an item to cart. That one user has created two sessions.

Common Use Cases

  • Conversion rate analysis: understanding how many sessions lead to purchases
  • Traffic quality assessment: evaluating whether sessions are engaged or bouncing
  • Marketing performance: measuring the impact of campaigns
  • UX optimisation: identifying friction points in the journey

What Sessions Really Tell Us

When we look at sessions through a systems lens, they become a window into how people explore, evaluate, and interact with a brand. The session count is just the surface. The deeper insight comes from understanding what customers do within those sessions: where they hesitate, what they search for, what they don’t do, and what makes them leave.

Sessions also reveal the cross‑functional dynamics behind the scenes. If marketing drives the wrong traffic, sessions rise but engagement drops. If UX is confusing, sessions become short and unproductive. If product content is weak, sessions don’t convert. The system reminds us that sessions are shaped by every part of the experience not just acquisition.

At its core, a session is a human story. It reflects curiosity, intent, exploration, and decision‑making. When brands treat sessions not as numbers but as signals, they unlock better journeys, more empathetic design, and more sustainable growth. That’s the heart of modern ecommerce: understanding not just how many people visit, but how they feel and behave while they’re there.
