Segmentation
01 Definition
Segmentation meaning: Dividing an audience into smaller groups that share traits or behavior.
Segmentation splits users into groups by shared attributes such as source, device, location, or past behavior. Analyzing each segment separately reveals patterns that a single overall average hides. It guides targeting, personalization, and reporting, though very small segments can produce unstable numbers that swing on little data.

Why it matters
How Segmentation fits the work
Segmentation turns a blurry site-wide average into specific insights, showing which audiences behave differently so you can act on their needs.
In context
Segmentation by device showed mobile users converted at 2 percent while desktop users converted at 5 percent on the same page.
Practical note
Slicing data into many tiny segments produces noisy figures and invites cherry-picking. Keep segments large enough to be stable and define them before you go looking for patterns.
