Merge tags let you dynamically personalize a page using values passed in the page URL.

They allow you to display different content to each visitor without creating multiple pages.

What is a Merge Tag?

A merge tag is a placeholder written like this:

{{name}}

When someone opens your page with a matching value in the URL, the placeholder is automatically replaced.

Basic Example

Page URL

<https://fastpage.app/welcome?name=John>

Page Content

Hi {{name}}

What the visitor sees

Hi john

Case-Sensitive Formatting

Merge tags automatically adapt the text case based on how you write them.

Merge tag URL value Result
{{name}} John john
{{Name}} John John
{{NAME}} John JOHN

This allows natural-looking text in titles, sentences, or headings.
