You reach out to a programmatic vendor and have your budget, your goals, and your flight dates ready. The vendor looks at what you provide and spits back a few targeting options and maybe an impression or click estimate. No insight into where their targets came from. No insights into where your ads are going to be location. No insight into what they’ll do on an ongoing basis to improve performance. But it’s the only game in town, so you play.
Midway through the campaign, you reach out and ask for some insights into how the campaign is doing. You get back a spreadsheet with a lot of the fields that you rely on to gauge the success of a campaign missing. So you reach out again - and get a little more data back.
Maybe, if you’re lucky, a few settings will be altered mid-flight. More than likely, you’ll get pushback saying that the system is optimizing and you shouldn’t mess with anything. After the campaign ends, you’ll get a report. It will be missing data. It will be missing a narrative. It will have limited insights.
