RSS Feeds Explained: What RSS Is, How It Works and What to Use It For

What is RSS and what is an RSS feed?

RSS is a plain text file that a website publishes to list its newest content in a fixed, machine-readable format. An RSS feed is that file for one particular site: the URL you can hand to a reader, a bot or an automation tool so it can see what is new without a human visiting the page. RSS stands for Really Simple Syndication, and the name is accurate — syndication is the whole idea. The site publishes once, and anything that understands the format can pick it up.

Nothing about it is proprietary. There is no account to create, no API key to request, no rate limit negotiated with a platform and no company in the middle that can change the terms. A feed is a file at an address. If you can open it in a browser, so can every tool you might want to use.

That matters more in 2026 than it did ten years ago. Social platforms have closed or restricted most of the ways one service could read another. RSS survived that entire period unchanged, because it never depended on anyone’s permission. A blog, a news site, a podcast, a YouTube channel, a forum, a job board and a government press office can all publish the same kind of file, and one tool can follow all of them.

Two things RSS is not: it is not a social network, and it is not a newsletter. It carries no audience, no comments and no metrics. It is infrastructure — the pipe, not the water.

The practical consequence is that a feed is worth having even if nobody subscribes to it by hand. It is the one address you can give to anything: a reader, a monitoring script, a partner site, an aggregator, an automation tool, or a colleague who wants your announcements in a chat channel. Everything later in this guide follows from that.

How RSS works

An RSS feed is an XML document. At the top it describes the channel — the site’s title, its address, a short description — and under that it lists the individual entries, each one wrapped in an <item> element. A reader or an automation tool fetches that URL on a schedule, compares what it finds with what it saw last time, and treats anything new as something to show or to act on.

Four fields inside each item do most of the work:

• title — the headline. On most destinations this is the line people actually read, so a feed with weak titles produces weak posts everywhere downstream.
• link — the address of the article itself. It must be absolute; a relative URL works on your own site and breaks in every external tool.
• guid — the unique identifier. This is how a tool knows whether it has already seen an entry. If a feed changes its guids, everything that reads it sees old articles as brand new.
• pubDate — when the entry was published. Wrong or missing dates are the single most common reason a feed behaves strangely in a reader.

Three details cause most of the confusion people run into. A feed usually holds only the last ten to twenty entries, not the site’s whole history — it is a window, not an archive. Some feeds carry the full article text and others only a summary, and that is a setting on the publishing platform rather than a property of RSS. And entries are ordered by the feed, not by you: a tool that reads it will normally treat anything with an unfamiliar guid as new, which is why republishing old posts with fresh identifiers causes a burst of unexpected activity downstream.

There are optional pieces too: description або content:encoded for the text, category for tags, and enclosure for an attached file, which is how podcast audio travels. We pulled the whole structure apart, field by field, in RSS feed XML anatomy explained: what guid and pubDate actually do.

RSS vs Atom vs JSON Feed

Three formats do the same job. RSS 2.0 is the oldest and by far the most common. Atom was written later as a stricter, better-specified alternative, and it is what YouTube and a number of publishing platforms serve. JSON Feed is the newest, expressing the same information as JSON instead of XML because that is easier for modern code to parse.

For a publisher the practical answer is that the difference rarely matters. Every serious reader and every serious automation tool handles all three, and if your platform emits Atom rather than RSS there is nothing to fix. The differences are in the field names — Atom uses entry where RSS uses item, updated where RSS uses pubDate, and an id instead of a guid.

The two comparisons in detail: Atom feed vs RSS feed: does it matter for auto-posting? та JSON Feed vs RSS: does the format matter?

How to find any site’s RSS feed

Most sites have a feed even when nothing on the page says so. Start with the three cheap checks, in this order:

1. Try the usual addresses. Додати /feed, /rss, /feed.xml, /rss.xml або /atom.xml to the site’s address. One of them works surprisingly often.
2. Look in the page source. Open the page, view source, and search for application/rss+xml. Sites that publish a feed usually announce it there even when no link is visible — that mechanism is called autodiscovery.
3. Check the platform’s own convention. Almost every hosted platform puts the feed in the same place for every site it runs.

The conventions worth memorising:

• WordPress — /feed/, plus a feed for every category and tag: how to find your WordPress RSS feed.
• Blogger and Blogspot — /feeds/posts/default: how to find your Blogspot feed link.
• Wix — /blog-feed.xml: how to find your Wix RSS feed.
• Ghost and Webflow — /rss/ and a collection feed: Ghost and Webflow feeds.
• Shopify and Squarespace — a blog feed on both, with different paths: Shopify and Squarespace feeds.
• Static site generators — Hugo, Jekyll and Eleventy each have their own: Hugo, Jekyll and Eleventy feeds.
• YouTube — every channel has an Atom feed keyed to its channel ID: YouTube channel feeds.
• Substack — /feed on the publication’s domain: the Substack feed guide.
• Medium — /feed/@username for a profile: the Medium feed guide.

If you publish rather than only read, the other half of this matters: making sure your own feed is discoverable. RSS feed autodiscovery covers the one line of HTML that does it.

Best RSS readers

A reader is an app that follows feeds and shows you what is new in one place, in order, with no algorithm deciding what you see. That last part is the whole appeal: a reader shows everything from the sources you chose, and nothing else.

The category has more good options than most people expect — hosted services that sync across devices, native apps for one platform, and self-hosted software you run yourself. What they share is the same input: a list of feed URLs, which you can move between them with an OPML file. That portability is deliberate, and it means switching readers costs you nothing. If you have collected a list worth keeping, the OPML guide explains how to export and import it.

Readers fall into three rough groups. Hosted services keep your subscriptions in the cloud and sync them across devices, which is the easiest option and the one most people should start with. Native apps for one platform tend to be faster and better at offline reading. Self-hosted software gives you full control and no third party at all, at the cost of running it yourself. All three read the same feeds.

Our current comparison is the best RSS reader apps in 2026, which also explains why a reader and an auto-poster solve different problems: a reader brings content to you, and an auto-poster sends your content out.

RSS feed generators: what to do when a site has no feed

Some sites genuinely have no feed — a shop, a single-page site, a listings page, an app that was never built with syndication in mind. A feed generator solves this by watching the page and producing an RSS file from what changes on it.

There are two kinds. Some generators scrape a page you point them at, and you tell them which part of the page is the list. Others turn a specific service into a feed — a search query, a marketplace category, a social profile. The scraping kind is more flexible and more fragile: when the site redesigns, the feed usually breaks, so treat it as something to check rather than set and forget.

Before reaching for one, it is worth checking whether the site already has a feed you missed. Many platforms publish one without linking to it anywhere, and a generated feed is always more fragile than the real thing.

We keep a working list in top 20 RSS feed generators to create an RSS feed for any website, including which ones are free and which need an account.

Is RSS dead in 2026?

No — but the reason people ask is fair. Google Reader closed in 2013, browsers quietly removed their feed buttons, and for most internet users RSS stopped being something they consciously used. It became invisible rather than obsolete.

Invisible is not the same as unused. Every podcast in the world is distributed over RSS; that is the entire mechanism by which an episode reaches Apple Podcasts, Spotify and every other app. News aggregators, price trackers, security advisories, research alerts, compliance monitoring and a large share of internal company dashboards all run on feeds. The format did not shrink — it moved from the front end to the plumbing.

The one honest caveat is that fewer readers find you through RSS than in 2010. Publishing a feed today is less about attracting subscribers and more about being machine-readable: it is how tools, aggregators and automations pick your content up. The numbers behind that are in is RSS dead in 2026? What the usage data actually shows.

RSS vs sitemap

They look similar — both are XML files listing URLs — and they are for different readers. A sitemap is written for search engines. It lists every URL you want crawled, old and new, and it exists so nothing gets missed. An RSS feed is written for people and tools. It lists only what is recent, usually the last ten to twenty entries, with the title and text included.

So a sitemap answers "what exists on this site?" and a feed answers "what is new on this site?". You want both, and they do not replace each other. Google has said for years that a feed can help it find fresh content quickly, but a feed alone will never give it the full picture of your site, and a sitemap will never drive an automation.

Using RSS for automation

This is where a feed earns its keep. Because it is a predictable file that updates when you publish, it can be the trigger for everything that should happen afterwards — without anyone copying a link.

That is what PostRSS does. You connect an account, you point a Target at a feed address, and every new item in that feed is published to the destination automatically. Feeds are checked every 5 minutes on all plans, and every minute on Enterprise. There are 66 social networks available across the plans, and the current list per plan is on the pricing page.

The destinations fall into a few families:

• Соціальні мережі — Facebook Pages, LinkedIn, X, Pinterest, Tumblr, VK and others.
• Messaging channels — Telegram channels, Discord, Viber, LINE, and regional platforms.
• Командні чати — Microsoft Viva Engage, Google Chat, Mattermost, Webex, Zulip, Rocket.Chat, Zoom Team Chat and several more, most of them through a single incoming webhook.
• Webhooks — Slack and Microsoft Teams via incoming webhooks, and the same Target type drives Zapier, n8n, Make or an endpoint you wrote yourself.
• The Fediverse — Mastodon, Bluesky, Misskey, Lemmy, Pixelfed and Nostr.
• Blogs and CMS platforms — WordPress, Blogger, Ghost, Wix Blog, Webflow CMS, DEV, Hatena and others, where a feed item becomes a full post rather than a link.

A concrete example makes the shape clearer. A podcast publishes an episode; the hosting platform updates the show’s feed within a minute or two; the automation sees the new item at the next check and posts the episode title and link to the channels the show cares about. Nobody opened a social app, and nothing was scheduled in advance. The same pattern works for a shop’s new arrivals, a newsroom’s press releases, a job board’s listings and a status page’s incident notices — anything that already produces a feed.

It also works in the other direction, into your own properties rather than out to an audience. A partner’s feed can land as posts on your site, and a curated hub can assemble itself from several sources, because blogs and CMS platforms are destinations too.

Two rules make the difference between automation that people follow and automation that people mute. First, send the narrow feed: most platforms expose a feed per category or tag, and a channel that joined for one subject does not want your whole site. Second, fix the source before you connect it — strong titles, absolute links, real publication dates — because every destination inherits whatever the feed contains. Our RSS feed optimization guide goes through that in order.

FAQ

What is an RSS feed in simple terms?

It is a file a website publishes listing its newest entries in a fixed format that software can read. You give the file’s address to a reader or an automation tool, and it sees new content as soon as it appears, without visiting the site.

How do I find the RSS feed of a website?

Try adding /feed, /rss або /rss.xml to the site address; if that fails, open the page source and search for application/rss+xml. Most hosted platforms use a fixed path — WordPress /feed/, Blogger /feeds/posts/default, Wix /blog-feed.xml.

Is RSS still used in 2026?

Yes, though mostly out of sight. Podcast distribution runs entirely on RSS, and news aggregators, monitoring tools and automations depend on it. What declined is the number of people reading feeds by hand in a reader app.

What is the difference between RSS and Atom?

They are two formats for the same job, with different field names. Atom is stricter and is what YouTube serves. Readers and automation tools handle both, so a publisher rarely needs to care which one their platform emits.

Do I need an RSS feed if I have a sitemap?

They serve different purposes. A sitemap lists everything for search engines; a feed lists only what is recent, with the content included, for people and tools. Most sites should have both.

Can I create an RSS feed for a site that does not have one?

Yes, with a feed generator that watches the page and builds a feed from what changes on it. Generators that scrape a page break when the site is redesigned, so check them occasionally rather than assuming they keep working.

Does an RSS feed cost anything?

No. RSS is an open format with no account, no API key and no company in the middle. Most publishing platforms generate a feed for you automatically, and reading one is free.

How often does an RSS feed update?

Whenever the site publishes something — there is no schedule built into the format. What you control is how often a tool checks it. PostRSS checks every 5 minutes on all plans, and every minute on Enterprise.

Why does my feed only show the latest posts?

Because that is what a feed is for. Most platforms include the last ten to twenty entries and drop older ones as new ones appear. If you need every URL listed, that is a sitemap’s job, not a feed’s.

How do I use an RSS feed to post to social media automatically?

Connect the destination account to an auto-posting tool, point it at the feed address, and every new item is published for you. With PostRSS the feed is checked every 5 minutes on all plans, and 66 social networks are available across the plans.
