The below are few tips to optimize audio files.
1. Optimizing landing page: Create a landing page for your audio. Briefly explain what your audio is about and encourage subscriptions. Explain clearly about the steps to be followed to subscribe or listen to your audio.
2. Keywords in URL: Use keywords in URL and file name while linking to an audio file. Use “hyphen” when using multiple words in a key phrase. Give a meaningful name to your file with keywords, as search engines read and notice file names.
3. Optimize audio file: Make your file clean and easy to understand. Use audio editor to remove noises in the background.
4. ID3 tags: These tags are like fingerprints of an audio file. Search engines spider these tags to extract and index the audio file information. Use keywords in title tags and description. If you are distributing a podcast, include pod cast name, title, URL, comments, pod cast transcript in the ID3 tags.
5. iTune tags: If you are trying to list your file in iTunes Music Store, include additional tags specific to iTunes in the RSS feed. You can do this by using a software called “FeedForAll”.
Use graphics for audio CD covers to attract more and more people.
6. Audio properties: Make sure that you declare the audio file type as “MIME ” and the file size in bytes, if you are distributing your file in a podcast. Few podcatchers use these details. So, if you do not mention these settings, you may miss out few subscribers.
7. RSS feed: Convert the transcription of your audio into RSS feed and distribute it. Use keywords in transcription. This may help your file get indexed by search engines and show results in RSS search engines and podcast directories.
