A feed that stops updating almost always has a specific, findable cause rather than being randomly broken. Working through a short, ordered checklist catches the overwhelming majority of cases faster than guessing.
Open your exact feed URL in a browser tab, separate from your site’s normal pages. If it loads an error page, a blank screen, or clearly stale content, the problem is on the feed-generation side (CMS, plugin, or server), not in whatever tool is supposed to be reading it. If it loads fine and shows your latest post, the feed itself is healthy and the problem is downstream.
A page-caching plugin or a CDN can serve a stale, previously-generated copy of your feed for minutes or hours after you publish something new, even though the live feed would show it if fetched fresh. Check whether your caching setup specifically excludes your feed URL (many caching plugins let you exclude paths like /feed/), or purge the cache and reload the feed URL to see if new content appears immediately after.
Automation and reader tools don’t watch your feed continuously — they check it on a schedule, often every few minutes to every hour depending on the plan or service. A post that “isn’t showing up” ten seconds after publishing usually just hasn’t been checked yet, not a broken integration. Confirm what interval your specific tool actually uses before assuming something is wrong.
A CMS core update, a new SEO or caching plugin, or a theme change can silently alter feed output without changing how your site looks to a normal visitor. If a feed was working and stopped right after any site-side update, that update is the most likely suspect — re-check the raw feed output specifically, not just the site’s normal pages.
Run the feed through a validator to catch structural issues a browser might silently tolerate but an automation tool won’t — a malformed <pubDate>, a missing or duplicated <guid>, or broken XML can all cause tools to skip content or stop detecting new items correctly, even while the feed appears to “load” normally.
Check the tool’s own activity log first — most automation dashboards show what they last detected, which tells you whether the tool is seeing your feed correctly or missing it, rather than guessing from the feed side alone.
Yes — some hosts apply aggressive server-level caching that isn’t visible in your CMS’s own caching settings; if plugin-level cache exclusions don’t fix it, ask your host specifically about caching rules for your feed URL.
Immediately, at the moment you publish — the feed itself should always reflect your latest content the instant you hit publish; any delay after that point comes from caching or from how often a downstream tool checks it, not from the feed generation itself.
A stalled RSS feed is almost always caching, an unnoticed site change, or a downstream tool’s check interval — rarely the feed format itself. Working through the feed URL directly, caching, polling interval, recent changes, and validation in that order finds the actual cause quickly instead of guessing.
