On the Pixel Segment page, you can create a Segment with the New button. Remember to generate Pixel code before creating a segment. You can collect people that you capture with pixel code in segments that you create. With these segments, you can set up campaigns and re-advertise them.
Add to Segment when a Pixel is called allows you to add the people you have captured with the pixel code you have created into the segment.
Exit Segment when a Pixel is called, allowing you to exclude people from the segment in the last step with the pixel code you have created again. For example, capture people who come to the Basket page, pay and exclude people who see the thank you page.
