Hello! I'm inquiring about the Growthbook Feature setting. I only want to expose the experiment to a specific site page (URL). (I want to apply this to this experiment only, not all experiments.) I wonder if I can proceed with the setting as shown in the image below. In addition, I wonder how it is different from the 'Test Feature Rules' function, and I wonder how to set it up to expose the experiment when connected only to a mobile device.

Hi Youngeun, I apologize for the delay due to the end-of-year holiday season. If you only want to expose the experiment on a specific web page, you'll need to use URL Targeting. For URL Targeting to work, you must pass the ​`url`​ targeting attribute into the GrowthBook SDK and also list it in the GrowthBook App. The configuration in the screenshot should work. Make sure you also pass this attribute into the GrowthBook SDK (this happens within your application code). By the way, are you using the Visual Editor for this experiment or making changes in your application code?
