# Replacement Variables

*Article Topics:* [*Design*](/getting-started/common-topics/design.md)*,* [*Blocks*](/getting-started/common-topics/blocks.md)

## What are Replacement Variables?

Replacement Variables are titled as such because they are variables replaced by data specified by the admin. Using replacement variables, you can display a wide variety of details, including your Tour/Member Area's name, a model's name, categories, and more.

## Using Replacement Variables

Replacement Variables are most prominently used on HTML Blocks, but can also be used on the header of List blocks and even on individual Page settings to change the Page Title.

### Page Titles

Page titles can be dynamically set based on the content presented on that page. Create the page and set the page title once using dynamic variables.

{% endcontent-ref %}

### Block Level Replacements

Dynamically set the name of a Set List Block header on a Model's page with their name.
