The problem this solves
Reddit sits on most media plans as a permanent maybe. The audience is real - buyers researching honestly in communities where marketing cannot fake its way in - and the auction is less crowded than the platforms everyone defaults to. But nobody on the team has the spare week to answer the qualifying questions: which subreddits your buyers actually inhabit, whether competitors are already there, what the costs look like, and what a credible first campaign would even be.
So the channel decision gets made by vibe, twice a year, in both directions. Someone argues Reddit users hate ads and the maybe dies; someone quotes a case study and a token budget gets sprayed at broad interest targeting, performs poorly for want of a plan, and confirms the skeptics. Either way the actual question - is there a specific, evidenced opportunity for us - never gets answered, and a possibly cheap channel stays unexplored while auction prices climb everywhere else.
How the mission runs
- Map where your buyers live on Reddit. Web Research identifies the subreddits where your category is genuinely discussed: community size, activity, how buying questions get asked and answered, and how commercial presence is received in each. The audience question gets a specific answer with named communities.
- Check the competitive presence. Reddit Ads and the public record reveal whether competitors are advertising there, and around what. An empty board can mean untapped opportunity or a graveyard; competitor persistence suggests the channel pays. Either reading is evidence you currently lack.
- Size the economics. The mission grounds expected CPM ranges and targeting options for the relevant communities, translating them into what a test budget would realistically buy in reach and frequency against the audience you mapped.
- Draft the starter plan. If the evidence supports a test, the agent designs it: target subreddits, creative approach fitted to Reddit's culture, budget, flight length, and the success thresholds that would justify scaling. If the evidence is weak, the plan says so plainly and states what would change the verdict.
- Write it all into a Google Doc. The full assessment lands as a Google Doc - findings, evidence, economics, and the starter plan - structured so a budget owner can read it in ten minutes and make the channel call with reasons attached.
The prompt
This is the exact objective the agent receives. Swap the obvious placeholders for your own domain, segment or channel and run it as-is from the console, Slack, or the API.
What comes back
A Google Doc that settles the Reddit question for your category: the named subreddits where your buyers actually are, the competitor presence and what it implies, realistic cost expectations, and either a concrete starter campaign plan with success thresholds or an evidenced recommendation to pass. The channel debate ends with a document instead of recurring quarterly as opinion.
Make it yours
- Run it for another maybe-channel: the same evidence-first structure qualifies any platform your team keeps debating without data.
- Deepen the community layer: add an organic-presence assessment covering how your team could participate credibly before ads enter.
- Revisit on a timer: if the verdict is pass, rerun in six months - community growth or competitor entry can flip the math.
Frequently asked questions
Will the mission launch a Reddit test itself?
This playbook delivers the assessment and the plan; launching is a separate, explicit decision. If you greenlight the test, a follow-up mission can build the campaigns - and like all ad writes on the platform, they would land paused for your approval before any spend begins.
What if the honest answer is that Reddit is wrong for us?
Then that is the deliverable, with the evidence attached. A clear, documented pass is worth real money - it ends a recurring debate and stops speculative budget from leaking into a channel that cannot support it. The doc also states what future signals would reopen the question.
How reliable are the cost expectations?
They are presented as grounded ranges rather than promises, since actual auction prices depend on your targeting and timing. The plan sizes the test budget so the ranges get validated cheaply, and the success thresholds are set against the conservative end.
