The 14-Day Learning Phase: Reddit Budget Decisions
Objective: Run a simulated 14-day Reddit Ads launch for a new product, making the bidding, comment-moderation, and scaling decisions a real campaign manager faces, with each choice routing to a realistically better or worse outcome.
You're testing Reddit as a new acquisition channel for Instacart+, the membership program, running a Conversation Ads campaign in r/MealPrepSunday, r/EatCheapAndHealthy, and r/instantpot with a $2,000 flight budget.
Manage manual CPC bidding through the learning phase, handle a hostile comment thread, decide when to switch to oCPM, and structure retargeting correctly at the end of the flight.
Before you start
What you'll need
Free path (everything below is enough to finish)
Free self-serve platform, no minimum spend to access
Free tracking log outside the ad platform's own reporting
Paid upgrades (optional, faster/deeper)
Useful once running Reddit alongside other paid channels, not needed for a single-platform flight
No access? Blend CPA numbers manually in the Google Sheets tracking log
The process
Simulation
Day 2, first dashboard check
Day 2 of 14The campaign launched 48 hours ago on manual CPC. You open the dashboard for the first time since launch.
Conversation Ads campaign - Instacart+ Trial Impressions 18,400 Clicks 92 CTR 0.5% Conversions 2 CVR 2.2% Cost per conversion $41.00 Spend to date $82.00
Two conversions in two days on manual CPC. What's the move?
Final deliverable
A day-by-day decision log for the 14-day flight plus a retargeting-ready ad group structure for the next campaign.

Hims and Hers, learning-phase decision log (excerpt) Day 2: 2 conversions, held manual CPC, no action taken Day 5: hostile top comment (290 upvotes) in r/tressless, responded within 90 min, CTR recovered by day 6 Day 9: 52 conversions reached, switched to oCPM Conversions Day 14: 94 total conversions at $16.80 CPA, retargeting pool of 3,800 moved into its own ad group with warmer creative for next flight
Success criteria
You're done when you can:
- Holds manual CPC through the early low-signal days instead of switching prematurely
- Responds to the hostile comment within the window instead of ignoring or mis-escalating it
- Switches to oCPM only after crossing the 50-conversion threshold
- Structures retargeting as a separate ad group with distinct creative at the end
