# 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.
