Subreddit analytics: can you post there, when, and who writes there
Subreddits is the subreddit analytics report in KissMyPost, for anyone about to post in a community they don't know well. One page per subreddit answers four things: whether your account can post there, when to post, what to post and who writes there. It shows the karma and account-age minimum where we can find it and scores all 168 hours of the week.
Included in every plan. $1 for the first 24 hours, then the plan's full monthly price. Cancel anytime in one click.

What Subreddits does
Can you post
Posting rules lists the post types a subreddit accepts and whether flair and body text are required. Community rules quotes the subreddit's own rules word for word where we have them.
Account requirements
The checks Reddit runs before it accepts a post, plus the minimum itself: stated in the subreddit's AutoModerator messages, or estimated from which accounts got through. Posts removed, by account age shows the pattern, and when nothing is known the card says No published minimum.
When to post
Best posting time scores all 168 hours of the week, with By day and Best hour beside it. Removal risk counts removed posts out of every 100 over the last 6 months, next to seasonality, member growth and activity.
What to post
Title length, body length, media and format, and the topics people post about, each with how posts of that kind fared in this subreddit.
Who writes here
Gender, country, jobs and age of the accounts that post and comment, which is a different crowd from the subscriber count.
How they talk
The intents behind its threads, the words and phrases it uses far more than Reddit as a whole, the brands and domains it names, its language and tone. The Conversations tab lists the posts behind each intent.

What Subreddits doesn't do
Here is what it won't do, so you know before you start.
- It doesn't say why one particular post was removed. Removal risk is a rate for the whole subreddit.
- One subreddit per page, with no side-by-side comparison. To compare who is in two subreddits, use Playground, which is free; for a set of subreddits, use Audiences or Find Subs.
- There is no export of the report.
- Community rules text is missing for many subreddits, and some run an account check we can't put a number on. Those cards say so instead of guessing.
Subreddits: common questions
How do I check a subreddit's karma requirements?
Open the subreddit in KissMyPost and read Account requirements. It shows the checks Reddit runs and, where we have it, the minimum itself, taken from the subreddit's AutoModerator messages or estimated from which accounts got through.
Does Reddit show a subreddit's minimum karma?
It marks that a check exists, not the number. Of 8,545 subreddits with 100,000+ members, Reddit marks 2,652 as running a karma or account-age check, and we have the actual minimum for 2,404 of the 8,545 (as of September 2026 data).
What is the best time to post in a specific subreddit?
Look at Best posting time on that subreddit's page: all 168 hours of the week, scored from how posts in each hour did there. In 5,779 of 8,164 subreddits with 100,000+ members timing barely matters, and the page tells you when that is the case.
Can I see a subreddit's demographics?
Yes, in Who writes here: gender, country, jobs and age of everyone who posts or comments in it. Accounts that only read leave no trace, so they aren't counted.
What does subreddit analytics in KissMyPost include?
Posting rules, account requirements and community rules; best hours, removal risk, seasonality and growth; title length, format and topics; who writes there; and how they talk, from intents to brands and domains.
Is the subreddit report free?
Partly. Any subreddit has a free summary at kissmypost.com/subreddit/<name>: At a glance, best posting time, member growth, activity, top topics and the brands people mention, for 3 subreddits a day. The full report, with rules, removals, what to post, who writes there and how they talk, comes with every KissMyPost plan, and any plan can be tried for a day.
