High Density Interval (HDI)

In marketing, a hypothesis is a clear assumption or prediction made before running an experiment. It defines what change is being tested and the expected outcome.

Hyper-personalization is tailoring marketing messages to individuals using real-time data such as behavior, browsing history, or purchase patterns. It goes beyond simple segmentation by creating experiences unique to each user.

In marketing analytics, a High Density Interval is a statistical range that shows where most likely values for a measurement lie. It is often used in predictive models to describe uncertainty.

Hesitation time measures how long users pause before interacting with a form field or webpage element. It indicates confusion, uncertainty, or difficulty in decision-making.

A hero image is a large, prominent banner placed at the top of a webpage, often on the homepage or landing page. It usually includes visuals and a call-to-action that introduces the brand or key offer.

Heatmaps are visual tools that show where users click, scroll, or focus their attention on a webpage. They help marketers see which areas draw the most interaction and which sections are ignored.
