Select the Project you wish to edit, and then navigate to the "Triggers" page.
On the Triggers page under #3 below, you have option to setup a RegEx to match or exclude certain pages based on the URL.
For instance, if you only wanted to show the project on pages that are in the "pricing" directory, you could simple input: pricing
If you wanted to show only on two directories, you could use the "|" character. Like this: pricing|product
If you wanted to show the project on the root of your home page, you could put a "$" on the end of your domain like this: www.ignitefeedback.com$
Almost any logical expression is possible, so you might want to try a websearch for regex to learn more.
