What is Metadata?
Metadata is descriptive information about your podcast episode that helps platforms, players, and search engines understand what your content is about. It includes titles, descriptions, tags, and embedded file information.
Why Metadata Matters for Podcasters
Metadata is the information that describes your podcast content—everything from your episode title and description to embedded file tags and RSS feed data. For podcasters, metadata exists in multiple places: your RSS feed (which includes episode titles, descriptions, publication dates, and categories), your audio file's ID3 tags (embedded in the MP3 itself), and your hosting platform's database. Good metadata is crucial for discoverability. Search engines, podcast directories, and recommendation algorithms all use metadata to understand your content and match it with listeners' interests. Your episode title is metadata that appears in search results and directory listings. Your description is metadata that helps listeners decide whether to click play. Categories and tags are metadata that help platforms group your show with similar content. Even your cover art filename and alt text are metadata that improve accessibility and SEO. The key is consistency—your episode title in your RSS feed should match your ID3 tag title, your description should accurately reflect your content, and your categories should align with your show's actual topics. Many podcasters overlook metadata, but it's one of the easiest ways to improve discoverability without changing your content. Search engines can't listen to your audio, so they rely entirely on metadata to understand and index your podcast.

ID3 Tags
ID3 tags are metadata embedded directly into MP3 audio files that store information like the episode title, artist name, album name, and cover art. They help podcast players display the correct information about your episodes.
Background Noise / Noise Floor
Background noise (also called noise floor) is the unwanted ambient sound present in your recording, such as air conditioning hum, computer fan noise, or room echo. It can distract listeners and make your podcast sound unprofessional.
Transcription
Transcription is the process of converting spoken audio into written text. For podcasters, transcriptions make content accessible, improve SEO, and enable repurposing into blog posts or social media content.
WAV vs MP3
WAV is an uncompressed audio format that preserves full audio quality but creates large files, while MP3 is a compressed format that reduces file size significantly with minimal quality loss. Most podcasters use MP3 for distribution.
