How quickly does an automation tool actually notice a new post and publish it to social media? The honest answer depends entirely on how often the tool checks (polls) your feed — and understanding that mechanic explains both what to expect and why paying for a faster interval sometimes genuinely matters.
RSS itself has no built-in push mechanism — a feed doesn’t notify subscribers the moment something new is published. Instead, every automation tool works by polling: periodically re-fetching the feed URL and comparing it against what it saw last time, then acting on anything new. This means there’s always some delay between publishing and posting, bounded by how frequently the polling happens, even on the fastest available automation setup.
| Plan Tier | Check Interval | Worst-Case Delay |
|---|---|---|
| Free / Start / Professional | Every 5 minutes | Just under 5 minutes |
| Enterprise tiers | Every 1 minute | Just under 1 minute |
“Worst-case delay” here means the maximum possible wait: if your article publishes one second after a check just happened, you wait almost the full interval for the next check. On average, actual delay is roughly half the interval, since publishing timing relative to the poll cycle is effectively random.
For the overwhelming majority of publishers — blogs, small businesses, most content sites — a few minutes of delay before a social post appears is genuinely inconsequential; almost no audience notices or cares whether a post went live at 2:03pm or 2:07pm. Faster polling matters in narrower, specific cases: breaking news operations where being first matters competitively, time-sensitive announcements (a flash sale, a live event update), or extremely high-volume publishers where a backlog of unposted items could otherwise build up between slower checks.
This is a deliberate constraint, not a limitation nobody’s solved. Polling a feed extremely frequently (every few seconds) across thousands of connected feeds creates meaningful server load, both for the automation platform and for the websites whose feeds are being checked that often — a small site’s hosting could genuinely strain under very frequent automated requests from many different tools simultaneously. Reasonable polling intervals (minutes, not seconds) are effectively an informal industry norm balancing responsiveness against not overloading the web’s infrastructure.
On each check, PostRSS fetches your feed, compares each item’s unique identifier (typically the GUID or link) against what it has already processed, and treats anything new as an item to post. This is why a properly functioning feed with unique, stable identifiers per item is important — it’s exactly how “new” gets determined, and it’s also why a feed validation issue (duplicate GUIDs, for instance) can cause posting problems independent of how often the feed is checked.
Yes — on the next check after publishing, all new items detected in that single poll are typically processed together, though the exact posting order and any spacing between them depends on the specific automation tool’s internal handling of multiple simultaneous new items.
Check current plan documentation directly — polling frequency is generally tied to plan tier rather than individually configurable, since faster intervals have real infrastructure cost implications for the automation provider.
No — polling means every new item is eventually caught on the next check, not skipped; a slower interval only affects how long that takes, not whether it happens.
Some automation tools offer a manual “check now” option in their dashboard for exactly this situation — check whether your specific tool provides one if you need a time-sensitive post to go out without waiting for the next scheduled poll.
RSS automation delay is a direct function of polling frequency, not a flaw in the technology — every tool in this space, PostRSS included, works this way because RSS has no push mechanism. A few minutes’ delay is invisible to nearly every real-world use case; the cases where it genuinely matters (breaking news, time-sensitive announcements, very high volume) are exactly the cases where faster-tier plans with 1-minute polling exist to solve the problem.
