High Density Interval (HDI)

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.

For example, if conversion rates are predicted between 3% and 5% with 90% certainty, that range is the HDI. Marketers use HDI to make informed decisions despite data uncertainty. It shows not just an average but a likely range, helping teams understand risks and probabilities in campaigns.

Hypothesis

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

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.

Hesitation Time

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.

Hero Image

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

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.
