ReddGrow DocsSubreddits: Finding Your Audience
How ReddGrow discovers, evaluates, and targets relevant subreddits for your campaigns
ReddGrow automatically discovers and evaluates subreddits for your campaigns, finding communities where your product is relevant, scoring them by quality and engagement potential, and enforcing their rules so your comments fit in. The subreddits list also surfaces real-time account state per community: join status, active bans, and outstanding requirements.
AI-Powered Discovery
When you create a campaign, ReddGrow's discovery pipeline analyzes your product description and searches Reddit for communities whose topics, questions, and discussions align with what you offer.
Discovery looks for signals like:
- Subreddits where users ask questions your product answers
- Communities where your product category is regularly discussed
- Adjacent communities where your audience spends time
Each discovered subreddit goes through an enrichment process before being added to your campaign.
Guidelines Extraction
Before generating any comments for a subreddit, ReddGrow fetches and parses the community's rules and sidebar. The AI extracts:
- Posting restrictions — what types of content are banned
- Self-promotion policies — whether promotional content is allowed at all, and under what conditions
- Tone expectations — whether the community skews technical, casual, or professional
- Minimum requirements — karma thresholds, account age, flair requirements
These extracted guidelines are passed as context to the AI generator, so every comment is written with the subreddit's rules in mind.
Subreddit Badges
The subreddits list shows per-account state badges for each community:
| Badge | Meaning |
|---|---|
| Join | Your account is confirmed as a member of this subreddit |
| Ban | Your account has an active ban in this subreddit — drafts for this community are skipped |
| Requirement | The subreddit has a karma or account age requirement your account may not yet meet |
The join badge updates passively as you browse Reddit with the Chrome Extension active. Ban and requirement badges are updated from daily inbox scans. See Account Health for how bans are detected and managed.
Relevancy and Ban Risk Scores
Each subreddit in your campaign shows two scores:
- Relevancy — how well the subreddit's topic matches your product and campaign goals. Higher-relevancy subreddits are prioritized for promotional drafts.
- Ban Risk — a signal indicating how likely the subreddit is to result in a ban event based on moderation patterns and past activity. Higher ban risk subreddits warrant more careful copy and may use awareness-only drafts.
These scores are computed during enrichment and updated over time.
Tier System
Each subreddit is scored on a 1–5 tier scale based on relevance, engagement quality, and community health:
| Tier | Meaning |
|---|---|
| Tier 1 | Highest relevance and engagement — primary targets |
| Tier 2 | Strong relevance, slightly lower priority |
| Tier 3 | Moderate relevance — good volume plays |
| Tier 4 | Peripheral relevance — used for warmup and reach |
| Tier 5 | Low relevance — warmup-only or excluded |
Higher-tier subreddits receive more frequent scanning and are prioritized for promotional draft slots.
Minimum Karma Thresholds
Each subreddit has a configurable minimum karma threshold. The scanner checks your account's current karma before assigning drafts to a subreddit — if your account hasn't met the threshold, that subreddit is skipped until you've warmed up sufficiently.
This threshold is set automatically during discovery based on the subreddit's typical account requirements, but you can adjust it manually.
Campaign Linking
Subreddits are always associated with a specific campaign. When you link a subreddit to a campaign:
- ReddGrow starts scanning it for relevant posts
- Drafts generated for that subreddit inherit the campaign's AI configuration and advocate assignment
- Subreddit-specific guidelines are combined with campaign-level instructions for generation
You can add or remove subreddits from a campaign at any time. Removing a subreddit stops future draft generation for it but doesn't delete existing drafts.
Adding Subreddits by Name (CSV Import)
In addition to AI-powered discovery, you can import subreddits by name using a CSV file. The import accepts subreddit names only — one per row. After import, ReddGrow enriches each subreddit automatically: fetching guidelines, computing tier and relevancy scores, and extracting requirements.
The import page includes a Claude-powered AI research prompt that you can use to generate a list of relevant subreddit names based on your product or niche, which you can then paste into a CSV for bulk import.
The member count for each subreddit is displayed in a normalized format (e.g., 1.2M, 340K) derived from a regularly updated subscriber count, so the numbers stay consistent regardless of how the raw data is formatted on Reddit.
