Podzinger and blinkx are two new search engines that are revolutionizing the way we can search for podcasts, and more significantly, the way we should be creating podcasts. Both engines scour the actual audio content for keywords related to searches, as opposed to relying on the meta data, title or tags for search relevance. How are they able to do this? They are translating the audio content into text and then search that text for keywords related to a search. The implication for SEO concerned podcasters is that there is now the need to be certain your audio content is optimized with your target keywords.
