I like how easy it is, my customers love getting their own ads online with our software! It's so much easier than dealing directly w/ Google or Bing Ads platform & we have more control over what they show (vs just showing generic text).
We're not seeing any problems at this time but there are some bugs from previous versions of D-Iux which has been resolved since then. If you want something very similar to GCP - definitely check out D J AX before going elsewhere as its really comparable product + ease of use makes things work well together without having too many issues between platforms / providers. Simple way to manage campaigns across multiple clients who run separate websites using different domains/subdomains etc., no need to do lots manual data entry when creating new accounts manually each month via spreadsheets where one person does everything including entering account details into.
