What We Offer

Advanced RSS Feed Validation Features

Everything you need to validate, debug, and optimise your RSS and Atom feeds for subscribers, search engines, and podcast platforms.

Live Feed Fetching

Fetches your RSS or Atom feed directly from the live server, so you always get validation results based on the current, published version of your feed.

XML Well-Formedness Check

Validates the XML structure of your feed for compliance with XML 1.0 standards. Malformed XML is the most common cause of broken feeds in readers and aggregators.

RSS 2.0 & Atom 1.0

Supports both major feed formats. Detects and validates RSS 2.0 and Atom 1.0 feeds automatically, checking against each format's specific required element rules.

Required Field Detection

Checks all required channel/feed-level and item/entry-level fields: title, link, description, pubDate, GUID/ID, author, and more — flagging any that are missing.

Duplicate GUID Detection

Scans all item GUIDs (Globally Unique Identifiers) to detect duplicates that would cause feed readers to merge or skip entries incorrectly.

Full Item-Level Audit

Audits every item in your feed individually, reporting on title, link, description, publish date, GUID, and author completeness in an easy-to-scan table.

Response Time Measurement

Measures your feed's server response time to help identify performance issues that may cause feed readers and podcast platforms to time out when fetching your feed.

CSV & TXT Export

Export your full feed audit — including all items, metadata, and detected issues — as CSV or plain text for client reports, documentation, or developer handoff.

What Is RSS Feed Validation and How Do You Test Your Feed?

An RSS feed (Really Simple Syndication) is an XML-based document that enables websites, blogs, podcasts, and news sources to broadcast content updates to subscribers, feed readers, and aggregator platforms. When a user subscribes to an RSS feed, any new content published on that site is automatically delivered to their reader — without needing to visit the website. This makes RSS a powerful tool for audience retention and content distribution.

RSS feed validation is the process of checking a feed's XML structure, required fields, and compliance with the RSS 2.0 or Atom 1.0 specification. A valid feed ensures it works correctly across all feed readers (Feedly, Inoreader, NewsBlur), podcast platforms (Apple Podcasts, Spotify, Google Podcasts), and search engine crawlers that use feeds for content discovery.

Common issues detected during validation include: malformed XML that breaks parsing entirely, missing required fields like title, link, and description at the channel level, missing item-level data like publication dates and GUIDs, duplicate GUIDs that cause feed readers to display stale or repeated content, incorrect character encoding, and invalid date formats in pubDate fields.

Our free RSS Feed Validator fetches your live feed directly from your server, parses all XML elements, and runs comprehensive checks for both RSS 2.0 and Atom 1.0 formats. The item-level audit table lets you spot exactly which entries have missing or problematic fields, while the Issues tab lists each finding with a severity level — error, warning, or informational — so you can prioritise fixes efficiently.

Regularly validating your RSS feed is especially important for podcast creators, as podcast directories like Apple Podcasts and Spotify enforce strict feed compliance standards. A single XML error can prevent your entire podcast from being indexed or updated. Whether you manage a blog, news site, or podcast, use this tool as part of your regular content and SEO maintenance workflow.

Common Questions

RSS Feed Validator – Frequently Asked Questions

Answers to the most common questions about RSS validation, Atom feeds, and feed best practices.

An RSS feed validator checks your RSS or Atom feed for XML errors, missing required fields, duplicate GUIDs, and compliance with feed format specifications. It ensures your feed works correctly in all feed readers, podcast platforms, and aggregators.

Most platforms expose your feed at predictable paths: WordPress blogs typically use /feed/, Ghost uses /rss/, Medium uses /feed, and Blogger uses /feeds/posts/default?alt=rss. You can also look for a link tag with type="application/rss+xml" in the HTML source of your homepage.

RSS 2.0 is the most widely deployed syndication format, popular for blogs and news sites. Atom 1.0 is a more strictly defined format with namespace support, required unique IDs for entries, and clearer content type handling. Both serve the same syndication purpose and our validator supports both.

Duplicate items in feed readers are most commonly caused by missing or changing GUIDs (Globally Unique Identifiers). When a GUID changes for an existing item — or when multiple items share the same GUID — feed readers cannot correctly identify whether the item is new or old. Use permanent, stable URLs as GUIDs and our validator will flag any duplicates.

Yes, indirectly. Well-structured RSS feeds help search engines discover new content faster. Podcast feeds with valid metadata are indexed by Google Podcasts and Spotify. Syndicated content from valid feeds generates backlinks and referral traffic. Feed errors can prevent distribution to platforms entirely, reducing your content's reach.

Best practice is to include the most recent 10 to 50 items. Extremely long feeds increase file size and load time, which can cause feed readers and podcast apps to time out. Our validator will flag feeds with over 100 items so you can consider limiting the feed to recent entries only.

Yes — completely free, with no registration, API key, or credit card required. Enter any feed URL and receive a full validation report covering XML validity, feed metadata, required fields, item completeness, and export options.
