I am a marketer responsible for setting up a new campaign on our Sitecore website. We have content which we want to target at a very specific customer segment -- customers from a specific Geo on mobile who are coming in from links for our new campaign. I know how to set up the personalization rule for this, but I need to do it on dozens of pages. Is there a way I can do this without having to configure this complex rule on every page?
You can create complex conditions consisting of multiple rules in the Marketing Control Panel under Personalization > Predefined Rules (in 8.2, but similar location in earlier versions) - You can then treat the entire condition as a single rule where the condition is true, and apply this single rule to all applicable pages.
You can then utilize the "where predefined condition is true" rule condition to reuse this complex condition.
