Triggering pages with URL Parameters

If you wish to selectively trigger your campaigns for visitors coming from pages with additional URL parameters  - for example 

https://cakes.com/Birthday-Cakes?ppc=true

DO NOT add the full URL (with parameter) in your 'Where to Show' settings - The platform will simply strip the parameter off the URL and the campaign will show on all pages with the basic URL 

Instead, simply add the URL parameter ONLY in your selectivity box - 

So in this example, just enter 

ppc=true

The campaign will then display according to your selected parameters, and not for other pages on your host domain
