Reddit has become the place where buyers check an answer before they trust it, and the place where ChatGPT, Perplexity and Google AI Overviews go to find that answer. That makes it a marketing channel with a strange shape: the brand that shows up best is usually the one that sells least. Brands weighing it have two options, run it in house or hire a Reddit marketing agency. This is an honest comparison of both, written for consumer brands in categories people research before buying.
The short answer
Run Reddit in house when you have one person who already uses Reddit, can give it five to eight hours a week indefinitely, and your category is not regulated. Hire an agency when nobody on the team is a Redditor, when the category is one where a wrong comment has legal or reputational cost, when you want AI citation tracking alongside the community work, or when you have tried it in house and the account got banned or went quiet after six weeks. The second scenario is the most common reason brands call us.
What in house Reddit actually requires
A real account with history. Reddit communities distrust new accounts and moderators remove posts from them on sight, so the first month is building karma in threads that have nothing to do with your product. A written disclosure policy, because the only sustainable way for a brand to be on Reddit is to say who it is. Five to eight hours a week of someone reading threads, answering questions and resisting the urge to link. A way to track which threads the AI engines are citing for your category, which is the part most in house teams skip because it is not obvious that it matters until a competitor’s thread starts showing up in ChatGPT answers.
The cost is mostly salary. A quarter of a marketing manager’s time is $20,000 to $30,000 a year in loaded cost, and the risk is concentrated: one bad week can get the brand handle banned from the subreddit where your buyers live, and there is no appeal process that works quickly.
What a Reddit marketing agency actually does
A specialist agency starts with a subreddit audit: the 2 to 5 communities where your buyers compare options, who moderates them, what gets removed, and which threads the AI engines already cite for your category. It builds and runs your branded subreddit and official handle, engages where the community welcomes it, seeds threads that answer the questions people type, and tracks 30 to 50 prompts across the AI engines so you can see what they say about you and who they cite instead. Every comment comes from a transparent, role based account. No persona accounts, no astroturfing, because a ban costs more than a year of the program.
Pricing at Quimby Digital: Foundation is $6,500 a month for 2 to 5 subreddits, about 30 tracked prompts, a branded handle, weekly engagement and a monthly AI visibility report. Enterprise is custom from $14,000 a month. Onboarding is $2,500. Engagements start with a 90 day minimum, because AI citation shifts take that long to appear, then move to an annual agreement with a 60 day termination clause. The full scope is on the Reddit marketing agency page.
Side by side
| Question | In house | Reddit agency |
|---|---|---|
| Time to a credible account | 4 to 8 weeks of karma building | Existing role based accounts plus your branded handle from week one |
| Weekly hours | 5 to 8 from a marketer | 1 to 2 for approvals |
| Subreddit selection | Guesswork unless someone is already a member | Audit of moderation, removal patterns and AI citation |
| Ban risk | High in the first 90 days | Low, with a disclosure policy moderators have seen before |
| AI citation tracking | Usually none | 30 to 50 prompts across ChatGPT, Perplexity, Gemini and AI Overviews |
| Annual cost | $20,000 to $30,000 in salary time | $78,000 at Foundation plus onboarding |
| Best for | Unregulated products, a team member who is already a Redditor | Regulated or high consideration products, lean teams, brands that want the AI visibility measured |
The number that decides it
The agency costs more in cash, by a wide margin. The question is what the Reddit footprint is worth. For a brand selling a $200 product where 30 percent of buyers search before purchase, showing up as the honest answer in the three threads ChatGPT cites for “best breast pump for exclusive pumping” is worth more than a month of paid social. For a $12 impulse product, it is not, and no agency should tell you otherwise. Our audit says which one you are before you spend anything.
Where each one breaks
In house breaks on consistency. The marketer who was excited in January has a product launch in March and the handle goes dark, which Reddit notices. It also breaks on tone: the brand voice that works on Instagram reads as an ad on Reddit and gets removed. And it breaks on measurement, because nobody is watching which threads the engines pick up.
Agencies break when they run persona accounts. Some do. If an agency will not show you the accounts it posts from and the disclosure policy it uses, walk away, because the ban will land on your brand and not on them. They also break when they promise AI citations in 30 days. The engines recrawl and reweight on their own schedule, usually two to four months, and anyone promising faster is counting something else.
How to decide
If someone on your team already spends time on Reddit as a person, give them a disclosure policy and six months and see what happens. If not, or if your category is one where a careless comment carries real cost, hire for it. Either way, start tracking what the AI engines say about your category this month, because that number is what you are really trying to move.
