Media plan launches Monday. Client emails Friday. "How's it performing?"
The first two weeks of a media plan is the learning phase, not the performance phase.
Platforms are gathering signal. Algorithms are calibrating. Early data is directional, not definitive. A decision made in the first 14 days based on conversion data is a decision made on noise, not signal.
Here's what's actually happening in weeks one and two:
Platforms are identifying which users in your target audience respond to which creative. Click-through rates are artificially variable while the system finds its footing. Conversion data is incomplete because attribution windows haven't closed. Creative fatigue hasn't set in yet, so early CTR doesn't predict sustained performance.
The two-week check-in isn't a performance review. It's a directional pulse, are we pointed in the right direction? Are there obvious setup problems? Is tracking firing correctly?
Calling a media plan at two weeks is like reading a book's first chapter and deciding how the ending goes.
What's the earliest you'll make a meaningful optimization decision on a new campaign, and what data point triggers it?
