Digital marketing and programmatic advertising - TRAFFICKING. Everyone hates it. It's 100% required but no one has solved the issue. It can eat up so much time and if you make a mistake can cost valueable data.
A mistake can mean - misconfiguring your target (wasting money on ads that won't give you an ROI), misconfiguring your 3rd party tracking (letting data like conversions go unaccounted for, or not having your auditing tags setup, meaning you show ads to fraudulent users that you otherwise wouldn't have to pay for), etc.
Alternatively, one place to manage creatives and language as well as targeting for each campaign might be helpful as we use google sheets, excel and Trello for this now.
