Can I post about my own company here?
Only if it links directly to recent peer-reviewed research or a professional media summary of that research, and the title is not editorialized or sensationalized.

Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.
Rule summary
- Must be peer-reviewed research: Submissions must directly link either to recently published peer-reviewed research or a professional media summary of that peer-reviewed research. [View all submission rules](https://www.reddit.com/r/science/wiki/rules#wiki_submission_rules)
- No summaries of summaries, rehosts, or reposts: Articles that obtain their information second-hand from other articles are not acceptable for submission. Websites that simply rehost press releases are prohibited. Reposting of existing, popular submissions is prohibited. No blogspam or media-only submissions. [View all submission rules](https://www.reddit.com/r/science/wiki/rules#wiki_submission_rules)
- No editorialized, sensationalized, or biased titles: The title and content of submissions should not be editorialized, sensationalized, or biased. All titles must adhere to our [headline rules](https://www.reddit.com/r/science/wiki/clickbait). [View all submission rules](https://www.reddit.com/r/science/wiki/rules#wiki_submission_rules)
- Research must be less than 6 months old: All submissions must have been published within the past six months. This time requirement refers to the publication date of the research, not the news article or web page. Ambiguous publication dates are determined by the first date of availability following peer review. This may be labeled as the 'Published Online' or 'Pre-Proof' date. [View all submission rules](https://www.reddit.com/r/science/wiki/rules#wiki_submission_rules)
- No off-topic comments, memes, low-effort comments or jokes: Comments must be on topic and not a meme or joke. Comments should constructively contribute to the discussion or be an attempt to learn more. This also means avoiding low-effort comments like "water is wet" or "correlation doesn’t prove causation." [View all comment rules](https://www.reddit.com/r/science/wiki/rules#wiki_comment_rules)
- No abusive or offensive comments: Abusive comments include those that disparage or attack other users of the subreddit. Offensive comments are those that denigrate individuals or groups based on group membership or inherent characteristics. This includes bigoted comments that are thinly veiled by leading/insincere questions or "just stating facts." [View all comment rules](https://www.reddit.com/r/science/wiki/rules#wiki_comment_rules)
- Non-professional personal anecdotes will be removed: Comments that only rely on a user's non-professional anecdotal evidence to confirm or refute a study will be removed (e.g. "I do that but that result doesn't happen to me"). Comments should be limited in personal details and scientific in nature. Including references to peer-reviewed research to support your claims is highly encouraged. [View all comment rules](https://www.reddit.com/r/science/wiki/rules#wiki_comment_rules)
- Criticism of published work should assume basic competence of the researchers and reviewers: Critiquing science is an important skill and one we want users to engage in but please try to do so with the assumption that the researchers who have spent years or decades in the field have already considered ideas that you came up with in a few minutes. Please also remember that individual studies sit within a larger corpus of work that may have already addressed your concern. [View all comment rules](https://www.reddit.com/r/science/wiki/rules#wiki_comment_rules)
- Comments dismissing established findings and fields of science must provide evidence: Comments that dispute well-established scientific concepts (e.g. gravity, vaccination, anthropogenic climate change, etc.) must be supported with appropriate peer-reviewed evidence. Links to personal blogs or 'skeptic' websites are not valid forms of evidence. Comments that dismiss entire fields of science (e.g., "that’s just a soft science") will also be removed. [View all comment rules](https://www.reddit.com/r/science/wiki/rules#wiki_comment_rules)
- No medical advice: Offering or seeking medical advice is strictly prohibited and offending comments will be removed. Discussions regarding the advantages and/or disadvantages of certain treatments, diets, or supplements are allowed as long as relevant and reputable evidence is provided.

Works well
- A direct link to a recently published peer-reviewed study, with a plain title that matches what the paper actually found.
- A professional media summary of new peer-reviewed research, as long as the article reports the study first-hand and does not just rehost a press release.
- A comment that adds scientific context to a posted study, citing peer-reviewed references to support your point.
- A careful, respectful critique of a study's methods that assumes the researchers knew what they were doing and engages with the wider body of work.
- A question in the comments aimed at learning more about the research, which the rules explicitly welcome.
Avoid
- Posting a blog post or press release that just summarizes someone else's coverage, which breaks “No summaries of summaries, rehosts, or reposts”.
- Writing a clickbait or exaggerated title, which breaks “No editorialized, sensationalized, or biased titles”.
- Linking to research that was published more than six months ago, which breaks “Research must be less than 6 months old”.
- Dropping a link to your product or landing page, since submissions must link to peer-reviewed research or a professional media summary of it.
- Leaving jokes, memes, or one-line comments like the low-effort examples the rules call out, which breaks “No off-topic comments, memes, low-effort comments or jokes”.
- Sharing your own story as proof a study is right or wrong, which breaks “Non-professional personal anecdotes will be removed”.
What r/science Is For
This community is a place to share and discuss new scientific research. People come here to read about the latest advances in astronomy, biology, medicine, physics, social science, and more. The description says you can find and submit new publications and popular science coverage of current research. So the room is built around one thing: actual studies, and serious conversation about them. The people posting are sharing publications or professional media coverage of those publications, and the people commenting are digging into the science.
Rules That Matter Before Posting
The rule that decides everything here is “Must be peer-reviewed research”. Your submission has to link directly to recently published peer-reviewed research, or to a professional media summary of that research. Anything else does not belong in this community. Then there is “No summaries of summaries, rehosts, or reposts”, which kills articles that got their information second-hand, sites that just rehost press releases, reposts of popular submissions, and blogspam. “No editorialized, sensationalized, or biased titles” means your headline has to be plain and accurate, no hype, no spin. “Research must be less than 6 months old” sets a clock on what you can share, and it refers to the publication date of the research itself, not the news article about it. On the comment side, “No off-topic comments, memes, low-effort comments or jokes” and “Non-professional personal anecdotes will be removed” shape how you are allowed to talk once your post is live. If you want to push back on a study, “Criticism of published work should assume basic competence of the researchers and reviewers” and “Comments dismissing established findings and fields of science must provide evidence” set the bar. And “No medical advice” is a hard line, offering it or asking for it is strictly prohibited.
What To Post
For a founder doing respectful Reddit marketing, the honest answer is that this community is not a place to promote anything. A good post here is a direct link to recent peer-reviewed research, published within the past six months, with a title that states plainly what the study found. If the research connects to your field, that is your angle: share the study because it is genuinely interesting, not because it sells something. If your company produced actual peer-reviewed research, that research can stand on its own here, as long as the link goes straight to the publication and the title follows the headline rules. Your marketing value in this community comes from the comments, where a thoughtful, scientific, on-topic contribution earns you credibility. Bring evidence, cite peer-reviewed work when you make a claim, and stay humble about what a single study can show.
What To Avoid
Do not submit anything that is not peer-reviewed research or a professional media summary of it. Do not submit articles that summarize other articles, rehosted press releases, reposts, blogspam, or media-only submissions. Do not write a sensationalized or biased title, and do not editorialize. Do not submit research older than six months, counting from the publication date of the research itself. In the comments, do not post jokes, memes, or low-effort remarks, do not offer or ask for medical advice, and do not lean on your own personal experience to confirm or refute a study. Do not attack other users or denigrate groups of people, and do not dismiss established scientific findings or entire fields without peer-reviewed evidence to back you up. If you critique a study, do it with respect for the people who spent years on it.

Common questions about r/science
How old can the research be?
The rules require the research itself to have been published within the past six months, based on the publication date of the study, not the article about it.
Can I submit a news article instead of the study itself?
Yes, the rules allow professional media summaries of peer-reviewed research, but not articles that get their information second-hand from other articles.
Can I ask a health question in the comments?
No. Offering or seeking medical advice is strictly prohibited, though discussing treatments or diets is allowed when reputable evidence is provided.
Can I question a study in the comments?
Yes, criticism is welcome, but assume the researchers and reviewers are competent, and back up any dispute of established science with peer-reviewed evidence.
