# What is a landing page in Smstools

A landing page is a unique URL that you can add to your SMS message. When the recipient clicks on this link, a page opens with additional information or a specific action.
What makes landing pages special is that they are unique per recipient. For example, if you send a campaign to 100 people, each person receives their own unique URL.

### Important: Do not modify the URL
It is very important that the URL is not altered in the message.
The URL contains a unique code, for example:
* [CODE] → this is an automatically generated unique code per recipient
In addition, the URL also contains a namespace. This ensures that the landing page remains correctly linked to the appropriate campaign or content.
||| Neither the [CODE] nor the namespace may be modified, removed, or changed. If this does happen, the landing page may not function correctly.

### What types of landing pages are there?
You can link three different types of content to a landing page:

### WEB
With the WEB option, you can display a simple web page.
* You set a title and text
* The recipient sees a page with this content when they click the link
This is useful for quickly sharing information without having to build a separate website.

### URL
With the URL option, you can redirect the user to an external website.
* You can shorten a long URL
* Ideal for links with UTM tags or tracking parameters
The recipient clicks the link in the SMS and is immediately redirected to the configured web page.

### PDF
With the PDF option, you can attach a document to the landing page.
* You upload a PDF file in the system
* When the recipient clicks the link, the PDF is opened or downloaded
This is especially useful for things like:
* Schedules
* Brochures
* Overviews or documents you want to share
