Hi @computerkid1,
Yes, it is. It’s actually one of our most popular usages.
General review of what you can do: https://www.if-so.com/google-ads
Step-by-step guide and a video tutorial: https://www.if-so.com/help/documentation/search-term-based-content/
Displaying sitewide content can be done using the recurrence option.
i.e. If> phone number > was displayed once; then: keep showing some phone number (during a session/always/for a specific time).
You can learn more in this link (though it’s only a checkbox that you need to check when you set the dynamic content):https://www.if-so.com/help/documentation/recurrence/
Not exactly what you asked but you might find it useful:
You can assign users who arrived from the ad to an audience and show audience-based content when they keep browsing other pages on the site. This option is useful if you want to show extra dynamic content (apart from the phone number).
