Now that you are podcating, the next question seems to be "how do I get more listeners?" or "How do I get more traffic." This usually leads to a discussion about Search Engine Optimization (SEO). Creating my Weekly Web Tools podcast, I often ran across many free tools for SEO at the Seo Book website. There is plenty of free information that they used to sell their book. ($79)
Now the book has grown into a series of tutorials to get you "in the know" quickly, as well as a communty that will trade secrets. The cost is $50 a month.
