The ability to build out custom campaigns for clients, as well has being able pull data from other platforms like Salesforce or Hubspot into our platform! Also love how easy it was implement new features once they were released by Google/Adobe (like remarketing). Nothing really - just make sure you have your account set up correctly before starting so there are no errors when building an ad group within CPANEL which will cause ads not show properly during testing phases of any project we work together towards solving their digital marketing needs & goals!! We've been using this product since 2013 until now where Adobe acquired them but still continue working closely wtih all team members who moved over after acquiring APB2 years ago because its such great support service at every level possible if needed :).
