ID3 Optimization

ID3 Optimization
By Sharon Housley

What Are ID3 Tags?

ID3 Tags contain the meta data behind an audio file. Search engines read the meta data in an attempt to classify the audio content contained in the audio file. ID3 tags are often used in conjunction with MP3 files, as they allow information such as the Title, Artist, Album, Track Number, and other information about the file to be stored within the file itself.

What Is Really Contained In An ID3 Tag?

Audio search engines are increasing in popularity, but most search engines are text based and have a difficult time discerning the content contained inside an audio file. This is where the ID3 tags come into play. ID3 tags are sort of like fingerprints for audio files.

The maximum size for an ID3 tag is 256 megabytes and maximum frame size is 16 megabytes. The ID3 tag contains 39 pre-defined frames including copyright, content type, dates, content information, and space for files such as pictures. ID3 tags can contain lyrics and complete transcriptions of text. ID3 tags for podcasts will often contain full text transcripts of the podcast show.

How Do You Optimize ID3 Tags?

Many audio recording applications have built-in ID3 tag editors, but they often lack the full capacity and number of fields that are included in a stand-alone ID3 editor. In order to effectively optimize ID3 tags, use keywords and phrases in the tag title and description.

What To Include In Your ID3 Tags?

If you are preparing ID3 tags for a podcast, be sure to include the podcast name, title, comments, URL, perhaps song lyrics, or podcast transcript.

Why Use ID3 Tags?

Audio search engines often spider the ID3 tags and extract keywords in an attempt to categorize and index the audio files. By optimizing ID3 tags, you are assured that your audio file or podcast will be found in an audio search engine when a related search is conducted.
