The quality of our content, how quickly they produce great assets that can be used in any environment or device - not just web! I wish there were more tools available as well with this tool (or others like it) to track what's being worked with/on internally vs externally. We're solving problems related to user acquisition via native ads and other digital marketing methods such as SEO & SEM campaigns across multiple channels. I like that they have such an extensive library of content, both in-house as well as third party sources. They're very easy to work with too! The only thing about them which could be improved would be their ability to create more interactive forms (e.g., surveys) - but this isn't something that's unique to them either. We've used Opgen media several times now over different projects/tasks where it has been invaluable at bringing together all the various pieces required by our clients' teams.
