Common RSS Errors Checked by Feedometer
Ensure your syndication feed parses cleanly across Feedly, Apple Podcasts, Google News, and Mailchimp.
Unescaped XML Characters
Unescaped ampersands (`&`), quotes, or angle brackets break XML parsers. Feedometer verifies CDATA blocks and XML entities.
Invalid Date Formatting
RSS 2.0 requires RFC-822 formatted dates (e.g. `Wed, 09 Sep 2026 12:00:00 GMT`), while Atom requires ISO-8601 timestamps.
Server Latency & Timeouts
Feeds taking longer than 2000ms to respond cause aggregators to drop polling frequency or mark feeds as inactive.
MIME & SSL Directives
Verifies `Content-Type: application/rss+xml` headers and modern TLS certificates for secure content delivery.
