Subreddit stats reference
Reddit swapped the member count for 2 weekly stats. Those two, plus timing and rules, decide whether a community is worth a post.
Mockup with placeholder numbers, not a real subreddit
Unique people in the past 7 days on a 28-day rolling average. Anonymous app browsing and bots are left out.
Posts plus comments in the past 7 days. Removed content does not count.
Total members and 'online now' no longer show on public pages. Old.reddit.com shows neither the old nor the new numbers.
Want the same numbers week over week? See the subreddit tracker comparison. Hidden karma and account-age bars live on the subreddit posting requirements page.
Source: Reddit's help center. Moderators still see member count in Mod Insights for now, and Reddit says that goes later too.
Free mini tool
Divide weekly contributions by weekly visitors. More contributions per visitor means an audience that replies.
It gets 148 contributions per 1,000 weekly visitors, about 4.4x r/communityB. Compare communities in the same niche only. There is no official healthy number, and a higher ratio says people reply, not that they will buy.
Contributions per visitor is a MediaFast heuristic, not a Reddit metric. There is no official healthy number: rank subreddits in the same niche against each other.
Below 100K weekly visitors there is lighter competition for attention. Above it a community is high-traffic, so timing and fit matter more.
Per Reddit's moderation limits policy, since March 31, 2026 one person can moderate at most 5 high-traffic communities.
Worked examples
Three illustrative communities with made-up numbers. The point is the method, not the figures.
Community APeople reply. Read the rules, then post in the top window.
Community BHuge reach, but New never slows. Build history in comments first.
Community CA room of silent readers with no peak to aim for. Revisit later.
| Community | Weekly visitors | Weekly contributions | Per 1,000 visitors | Size tier | Activity pattern | Verdict |
|---|---|---|---|---|---|---|
| Community A, focused niche | 48K | 7.1K | 148 | Under the 100K line | Two clear weekday peaks | Prime candidate |
| Community B, huge general | 900K | 30K | 33 | High-traffic (over 100K) | Busy all day, no quiet gap | Comment first |
| Community C, big but quiet | 220K | 2.2K | 10 | High-traffic (over 100K) | Flat curve, no real peak | Skip for now |
Illustrative. Community A has about 15x the reply rate of Community C at less than a quarter of its size.
Timing
Every subreddit peaks when its own audience is awake. The analyzer turns those hours into 5 slots you can schedule.
Easy to timePost 30 to 60 minutes before a peak, so the post is fresh when the crowd arrives.
0 to 60 minNew posts need early votes and replies to climb. Land the first hour inside a top window.
No edgeEven or near zero all day? No timing gives your post an edge. Deprioritize the subreddit.
0 min: the post goes live in New. 15 min: first votes and replies. 30 min: it climbs if early signals land. 60 min: it is visible to the peak crowd.
Sitewide patterns live in the best time to post on Reddit guide, and the best time to post calculator works from your audience's timezone.
4-step workflow

Founders who picked the right subreddits
Real posts from founders using MediaFast to plan where and when to post on Reddit.
"Reddit has insane potential for founders. But most posts get removed. Most accounts get banned. Most strategies are guesswork. I've been using @mediafa_st to plan posts, find the right communities, and avoid bans."
"Should be $25k + $94 now. Just bought lifetime access"
"Things are going well mate thanks for you product. It helps me to step into reddit very intuitively!"
Rough guide
Mid-size, focused subreddits tend to win: enough reach, engaged enough that a good post is not buried. A starting point, not a verdict.
| What changes | Focused niche subreddit | Huge general subreddit |
|---|---|---|
| Conversation on posts | Replies from people who share the problem | Drive-by comments, if any |
| Self-promo tolerance | Often written and workable | Usually very low |
| Your post visibility | Can stay near the top for hours | Buried quickly by volume |
| Audience fit | Pre-qualified by topic | Broad, mostly not your buyer |
| Conversion potential | High, the audience is targeted | Low, the audience is too broad |
The data behind this page
Reddit keeps growing, but most of it sits in a few mega communities. The rest need to be judged on activity, not size.
Participation inequality90-9-1The split researchers find across large online communities. Why contributions beat audience size.
Nielsen Norman Group| Tool | What it shows | Who can use it | The catch |
|---|---|---|---|
| Reddit community page | Weekly visitors and weekly contributions for one subreddit | Anyone, apps and new reddit.com | One 7-day snapshot. No hourly view, no history, nothing on old.reddit.com |
| Mod Insights | Traffic, members and engagement for a community you run | That subreddit's moderators only | No help judging communities you do not moderate |
| GummySearch | Audience research, including subreddit info | Paid accounts made before Nov 30, 2025 | Shutting down and deleting data on Dec 1, 2026, no commercial Reddit Data API license |
| PRAW scripts (e.g. prawtools) | Custom stats pulled from the Reddit API | Developers with API credentials | Setup work, and listings stop at about 1,000 items, so long histories get cut off |
| This Subreddits Analyzer | Hourly heatmap, Power Score and the 5 best posting times for a shortlist | Anyone, free, no signup | Covers the subreddits in its list, not every community on Reddit |
GummySearch dates come from its own closing notice. Reddit user numbers come from the Q2 2026 earnings release.
Facts on this page were checked against Reddit's help center, SEC filings and the sources linked above in October 2026.
Generally, I've found more success participating in niche communities. Yes, the broad subreddits generally have a bigger user base, but there are so many comments on each thread that it's hard to stand out.
Before a human sees your post
A subreddit can look perfect in the stats and still hide your post. Every post passes these gates first.
| Filter | What it does | What you do |
|---|---|---|
| Reputation filter | Sitewide account signals hold likely spam before it reaches the community. | Keep a clean account history |
| Crowd Control | Signals from inside one community, so a low-history account can be collapsed there even with a clean record elsewhere. | Comment there before posting |
| Ban evasion filter | Catches accounts that look linked to people already banned from the subreddit. | Never rotate throwaway accounts |
| AutoModerator | Each community's own rules. Removal rules run first, and content a mod approved is not removed by it. | Karma and account-age checks live here |
| AI rule enforcement | New and beta communities can have their written rules enforced automatically with an LLM. | Rule wording matters before a mod looks |
| Karma gates | Some communities require a certain amount of karma to post. | Under the bar? It is comment-first for now |
Sources: Reddit's guide to keeping spam out, AutoModerator guide, rules page and karma page. The same guide says promotional content is not inherently spam. Run the shadowban check on your account before you start.
Decision tree
Run through these before publishing to any subreddit. Each check gives you a next action.
Check 01Check 02Check 03Check 04Check 05Check 06Check 07Check 08| Check | If yes | If no |
|---|---|---|
| 1. Does the subreddit have a real weekly audience? | Continue to check 2. | Skip it. Nobody there to surface your post. |
| 2. Are people posting and commenting every day? | Continue. | Mostly passive readers. Not worth targeting yet. |
| 3. Does your post stay visible in New for a few hours? | It gets a real window. Continue. | Only go if you hit a peak window with an exceptional title. |
| 4. Do the rules permit your type of content? | Continue. | Switch to a value-first post with no link. If even that is banned, drop it. |
| 5. Do typical posts get real comment threads? | Conversational audience. Continue. | Even a hit brings a few passive upvotes and little traffic. |
| 6. Does the Power Score show 50 or above? | 50 to 79 is solid, 80 or above is high priority. | Post once as a test, invest only after traction. |
| 7. Have you found the best 1 to 2 posting windows? | Schedule for that window and watch the first hour. | Run the analyzer first. The wrong hour wastes a good post. |
| 8. Does your account meet the karma or account-age bar? | Post. | AutoModerator will likely remove it. Comment helpfully first. |
Beyond Power Score and posting times, check these on Reddit itself before you commit to a subreddit.
| Metric | What it measures | Good sign | Red flag |
|---|---|---|---|
| Weekly visitors | Unique people in the past 7 days, 28-day rolling average (shown by Reddit) | A real weekly audience inside a community focused on your topic | A tiny weekly audience, or a huge general one with no niche focus |
| Weekly contributions | Posts plus comments in the past 7 days, removed content excluded (shown by Reddit) | Steady posting and commenting every day | Few contributions for the audience size: people read but never reply |
| Posts per day | How often new content is submitted | Your post stays visible in New for a few hours | New turns over in minutes, so your post is buried almost at once |
| Avg upvotes | Typical upvote count a post receives | Most posts in New collect some votes | The average post gets 1 or 2 upvotes: lurkers, bots or a dead community |
| Comment ratio | Average comments per post, a measure of conversational depth | Top posts carry real back and forth threads | Even top posts have almost no comments |
| Mod strictness | How often posts get removed, a proxy for rule enforcement | Clear written rules and predictable enforcement. Strict is fine | No visible rules, yet posts disappear constantly |
| Self-promo allowance | Whether you can share your own product or content | A weekly showcase thread, a promo flair, or value-first promo allowed | Rule 1 bans all promotion, and earlier promo posts sit at zero |
| Mistake | Fix |
|---|---|
| Choosing by subscriber count alone | Compare weekly visitors with weekly contributions. Reddit itself stopped leading with total members. |
| Reading votes without post volume | Every post gets votes in a sub with 2 posts a day. Cross-check with posts per day. |
| Skipping the rules before the first post | Read every rule first. One missed 'no links on weekdays' rule kills an hour of writing. |
| Posting whenever the draft is done | Schedule inside a top window from the analyzer so the first hour gets early votes. |
| Spreading across 40 subreddits at once | Pick 3 to 5 strong communities and build a real presence before expanding. |
| Confusing a strict subreddit with a bad one | Strict often means trusted content. Adapt your format to its standards. |
| Comparing ratios across different niches | Memes and B2B software never match. Compare only inside one niche. |

Common questions about subreddit stats, posting times and evaluating communities for marketing.
Open the subreddit on the Reddit app or new reddit.com and read the two numbers under its name: weekly visitors and weekly contributions. Then pick the same subreddit in the free analyzer above to see its hourly activity heatmap, a 0 to 100 Power Score and the 5 best times to post. Together that tells you who shows up, whether they talk, and when.
It pulls tracked posting and commenting activity for each subreddit you select and turns it into an hourly activity heatmap, so you can see when a community is busy instead of guessing. It also ranks the top 5 posting windows by activity and shows a Power Score for your selection, so you can compare a shortlist at a glance before you dig into the charts.
Yes. The Subreddits Analyzer is a free analyzer for Reddit communities with no signup or login. Pick the subreddits, press Analyze, and the results load on the page. MediaFast offers paid plans if you want help turning the shortlist into posts, but the subreddit stats tool itself costs nothing.
There is no single best time for all of Reddit, because every subreddit peaks when its own audience is awake. The analyzer ranks the 5 busiest hours for the subreddits you pick, in your timezone. Post inside one of those windows so the first hour, when a post needs early votes and replies, lands while people are online.
Reddit replaced the public total members count and the 'online now' number with weekly visitors and weekly contributions. Weekly visitors counts unique people in the past 7 days on a 28-day rolling average, without anonymous app browsing and bots. Weekly contributions counts posts and comments in the past 7 days, without removed content. The new stats show on the apps and new reddit.com, not on old.reddit.com.
No. Reddit itself moved away from it. A focused community where people post and comment every day usually beats a huge one where posts get buried in minutes. Compare weekly visitors with weekly contributions on the subreddit itself, then use the heatmap and best times above to see when that activity happens.
Power Score is a 0 to 100 snapshot MediaFast shows for the communities you select. It blends engagement density (how many people are active at peak against the subscriber base), posting and commenting volume, and how well the community size fits a sweet spot around 100k members. When no live activity comes back, it falls back to the size part alone and says so. Shortlist with Power Score, then confirm timing with the heatmap.
Yes. Select several subreddits and the analyzer builds one combined heatmap, one Power Score and one best times list for the whole selection. For a head-to-head verdict between 2 or 3 specific communities, the subreddit comparison tool is built for exactly that.
The timing comes from tracked activity, meaning when real users post and comment in each community. Reddit activity moves day to day, so treat the top windows as the best odds, not a guarantee. Post inside one of them, watch the first hour, and adjust.
No, this page analyzes communities. If you searched for a Reddit user analyzer, a Reddit account analyzer or a Reddit profile analyzer, use the MediaFast Reddit profile analyzer instead. It looks at one account's posting history, karma and activity rather than a subreddit's.
Not as a ranking. The analyzer gives a point-in-time view of activity and timing for the subreddits you pick. To watch the same numbers week over week, see the subreddit tracker page, which compares tools built for tracking growth over time.
Reddit's moderation limits policy defines a high-traffic community as one with more than 100K weekly visitors, and since March 31, 2026 one person can moderate at most 5 of them. It is a useful marker for marketers too: above that line competition for attention is heavier, so timing and fit matter even more.
GummySearch stopped new signups and payments on November 30, 2025 and says it will shut down and delete its data on December 1, 2026, because it could not get a commercial license for Reddit's Data API. If you used it to check subreddit stats, the free analyzer above covers activity, timing and a Power Score for your shortlist.
Reddit's Mod Insights are only visible to a subreddit's moderators and cover that one community. The Subreddits Analyzer works the other way around: it is built for marketers evaluating communities from the outside, works without moderator access, and turns tracked posting and commenting activity into an hourly heatmap and best times ranking.
