Connect your website’s RSS or Atom feed, filter it down to what a community actually wants, and PostRSS submits each new item to your chosen subreddit as a link post — with the title and the link, and nothing to remember after you publish.
Reddit is technically one of the easiest destinations to automate and by some distance the easiest to get wrong. The difference matters enough to put at the top rather than in a troubleshooting section at the bottom.
Posting itself is simple. A link post is a title and a URL, which is what an RSS item already is, so there is no format to adapt and nothing to truncate.
What decides whether it works is everything around the post. Each subreddit is an independent community with its own rules, its own moderators and its own AutoModerator configuration. Some welcome relevant links from people who show up. Some ban link posts entirely. Some require an account to have participated for weeks before it may post at all.
And Reddit’s failure mode is not an error message. It is your posts being removed, and then your account being banned from the communities you most wanted to reach. That outcome is permanent in practice, and no automation setting undoes it.
The rest of this page is largely about avoiding that — because the technical setup takes four minutes and the judgement takes rather longer.
Reddit’s widely cited guideline on self-promotion is the 90/10 rule: roughly nine parts genuine participation to one part promoting your own thing. It is not enforced by a counter somewhere, but moderators apply it, and communities notice accounts that only ever arrive to drop links.
An unfiltered feed is the clearest possible violation. An account that posts every article your site publishes, replies to nothing and comments nowhere is, by the only definition that matters, a spam account — regardless of how good the articles are.
Two things follow, and both shape how you configure this.
First, filter aggressively. The right number of automated posts to a community is usually one or two a month, not one or two a day. The question is not “which of my articles could go here” but “which of my articles would a member of this community have wanted to find”.
Second, the account has to be real. Automation handles the submitting; a person still has to read the community, answer questions under their own posts, and contribute elsewhere. An account that does both is a participant who also shares their work. An account that only does the first is a bot, and will be treated as one.
More automations fail here than at any configuration step.
The instinct is to find the biggest subreddit on your topic and point the feed at it. Large general communities are exactly where automated link posts do worst: they are the most heavily moderated, have the strictest self-promotion rules, and have seen every variation of this attempt already.
Smaller, more specific communities are where relevant links are genuinely welcome. A niche subreddit of eight thousand members interested precisely in what you write about will give you more traffic, better discussion and no moderator trouble, compared with a two-million-member community that removes the post within the hour.
Before connecting anything, do three things. Read the sidebar rules in full — many subreddits state their position on blogs and self-promotion explicitly. Search the subreddit for links from sites like yours and see whether they survived and whether anyone engaged. And look at what the community upvotes, which tells you more about fit than any rule text.
If the rules forbid link posts, or require a participation history you do not have, believe them. That subreddit is not a candidate, and posting anyway is how accounts get banned.
Three things are needed: an account with permission to post, a subreddit to post to, and a feed. In PostRSS each subreddit is a Target and each automated post counts as one Task against your plan’s monthly allowance.
Reddit uses OAuth, so connecting is an authorisation step rather than a password handover. You approve access and PostRSS receives a token that lets it submit posts on your behalf. Access can be revoked from your Reddit account settings at any time, which stops publishing immediately.
Each subreddit is connected as its own Target. This is deliberate: it makes it impossible to accidentally broadcast the same item to a dozen communities at once, which is the single fastest route to a site-wide spam classification.
Paste your RSS or Atom feed — on WordPress usually your domain followed by /feed/, with a feed available for every category and tag. Then narrow it. A category feed such as /category/research/feed/ is often a better starting point than the site feed plus filters — every WordPress category already exposes one, because it forces the decision earlier.
Do not skip this on Reddit. A publishing window prevents several posts arriving in quick succession, which is both a rule problem and a rate-limit problem. Reddit throttles how frequently an account may submit, and an automation that ignores that looks exactly like the behaviour the throttle exists to stop.
Three subreddit-level mechanisms decide whether a post survives its first minute.
Post flair is required by many communities, and AutoModerator removes unflaired posts automatically. If a subreddit requires flair, check whether your Target can supply it before assuming automation will work there.
Title rules are common and specific: some communities require a prefix such as [Article], some forbid editorialised titles, some require the original headline unchanged. Your feed emits one title, so a community whose rules conflict with your headlines is one to skip rather than fight.
AutoModerator also enforces account age and karma thresholds, domain blocklists and keyword rules. A brand-new account posting links will be removed in most substantial communities regardless of content quality. If your account is new, participate first and automate later.
Reddit has two submission types, and the distinction matters more than it looks.
A link post is a title and a URL. It is what an RSS item maps onto, it sends readers directly to your article, and it is what most subreddits mean when their rules discuss outside content.
A self post is a title and a body of text that stays on Reddit. Some communities allow only these, on the principle that discussion should happen in the community rather than on someone’s website. A few allow a link inside the text body.
If a target community permits only self posts, an automated link feed is not the right tool for it, and forcing one in is the kind of thing moderators remember. Use that community manually, and automate the ones where link posts are normal.
This deserves its own section because it is the most common serious mistake, and because automation makes it effortless.
Submitting one article across many communities in a short window is the pattern Reddit’s spam detection was built to catch. It also annoys the users who follow more than one of those subreddits, and moderators of related communities talk to each other.
If an article genuinely fits two communities, post it to one, and consider the second a week later with a title written for that audience — manually. The right structure with PostRSS is one Target per subreddit with different filters, so each community receives different articles rather than the same ones.
Reddit traffic behaves unlike anything else covered in these guides. Most posts do very little. Occasionally one finds the right community at the right moment and sends more readers in a day than the rest of your channels manage in a month. Tagging those links with UTM parameters is the only way to tell which community did it.
That distribution is why patience matters more than volume here. Posting more does not raise your chances proportionally; posting relevantly does. A feed filtered to the handful of articles that genuinely belong in a community will outperform one posting everything, by a wide margin, and will keep the account in good standing while it does.
It is also worth knowing that discussion is the point. A post that gets comments is a post Reddit shows to more people, and comments are where the actual value sits — the questions under an article are often more useful than the article’s own analytics.
It was almost certainly removed by AutoModerator or a moderator. Check the subreddit’s rules for flair requirements, account age or karma thresholds and domain rules. Removed posts are often invisible to everyone except you, which is why an automation can appear to work while achieving nothing — view the post while logged out to check.
Check that the Reddit connection is still authorised, and that the account is not banned from that subreddit. Also confirm the feed itself updated, since a feed that has quietly stopped refreshing looks identical to a broken automation.
Reddit throttles submission frequency, particularly for newer or low-karma accounts. Add a publishing window so posts are spaced out rather than submitted together.
That is a filter behaving as configured — and on this Target, a strict filter is usually deliberate.
Stop the Target for that community. Appeals occasionally succeed if you message the moderators politely and explain what you will change, but the honest answer is that prevention is the only reliable approach.
Each subreddit you connect is one Target, and each automated post is one Task against your plan’s monthly allowance. Paid plans raise both numbers and add the other networks, and they are chosen on postrss.com rather than inside the mobile app.
Reddit should be your cheapest Target by far. A well-filtered feed posting once or twice a month to each of three communities costs under ten Tasks — and that restraint is exactly what makes it work.
Reddit rewards restraint more than any other destination here, so it pairs well with places where volume is welcome. A Telegram channel or a Discord channel can carry everything you publish, leaving Reddit for the few items a community would genuinely want.
The rules that decide whether a post survives are a specific case of the wider subject covered in what actually violates platform terms of service — required reading before automating anywhere that has moderators.
Automation is not prohibited; using it to spam is. Reddit’s rules and each subreddit’s rules apply exactly as they would to manual posting, and moderators enforce them the same way.
No. Reddit uses OAuth, so connecting is an authorisation step. Access can be revoked from your Reddit account settings at any time.
You can, and you should not. Submitting the same item across communities in a short window is the pattern spam detection targets. Use one Target per subreddit with different filters.
Reddit’s guideline that roughly 90% of your activity should be genuine participation and no more than 10% self-promotion. An unfiltered feed breaks it immediately.
Usually AutoModerator: missing flair, insufficient account age or karma, a blocked domain, or a title that breaks the subreddit’s format rules. Check the sidebar rules first.
No. PostRSS publishes items that appear in the feed after the Target starts running.
The best subreddit to automate is one you were already part of before you had anything to promote. Read its rules, check that link posts are normal there, filter your feed down to the articles its members would genuinely want, set a publishing window, and then be present in the comments. Done that way, Reddit is one of the highest-value destinations on the list. Done carelessly, it is the only one where you can lose access permanently.
