What is the key difference between RSS 2.0 and Atom feeds?

RSS 2.0 uses and nodes with RFC 822 date formats (e.g. Wed, 07 Oct 2026 12:00:00 GMT), while Atom 1.0 uses and nodes with strict ISO 8601 timestamps (e.g. 2026-10-07T12:00:00Z) and standardized XML namespaces for richer extensibility.

Why do some RSS feeds fail to load when entering a URL?

Web browsers enforce CORS (Cross-Origin Resource Sharing). If a remote blog server does not serve an Access-Control-Allow-Origin: * HTTP header, browsers block direct fetches. Pasting the raw XML feed text bypasses CORS instantly.

What causes common XML parsing errors in RSS feeds?

The most frequent error is unescaped special characters in post descriptions—such as literal ampersands (& instead of &) or unclosed HTML tags inside non-CDATA blocks. Standard XML parsers immediately halt upon encountering unescaped characters.

What are RSS tags used for?

Enclosures attach multimedia files (audio MP3s, MP4 videos, PDF documents) to RSS items. They are the foundational technical mechanism behind podcasts, allowing podcast apps to automatically discover and download new episodes.

How often do RSS readers check feeds for new content?

RSS feeds can suggest a cache interval using the (time-to-live in minutes) tag or . Most modern feed aggregators poll active feeds every 15 to 60 minutes or use WebSub (PubSubHubbub) for instant real-time webhook push updates.
