# Landing Page criterion
Landing page is a triggering criterion that enables defining a [segment](/assets-library/creating-and-managing-segments.md).
To learn how to create a segment, please refer to this [article](/web-experimentation-and-personalization/targeting-step/how-to-create-a-segment-who-section.md).
## đź“– Definition
The landing page criterion allows you to trigger your campaign depending on which page your visitor landed during their visit on your website.
## ⚙️ Configuration
First, you will have to choose which operator you want to use to identify a page or a set of pages. Once you do, you can proceed and enter the specific URL or piece of URL that will identify the page(s) to target, depending on the operator chosen.
## 🔎 How does it work?
The AB Tasty tag captures every session’ first URL and stores it at the beginning of the session inside one of our cookies: `ABTastySession`. This information is always stored, for each and every session.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.abtasty.com/assets-library/creating-and-managing-triggers/list-of-trigger-criteria/landing-page-criterion.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
