How many ways can your prospects and clients consume your content? Remember, some people like to read, others like to listen, some like physical products, others like digital.
One of my clients is creating an audio program to use as a lead generator to build her list. She's having the audio transcribed and creating a special report from the text. I suggested that the special report would make an excellent ebook for Kindle.
While the audio and report will be free, the Kindle ebook can be priced as low as $.99 (no freebies on Kindle). The convenience of getting the content delivered instantly on one's Kindle device is worth 99 cents!
Here's another example. I have a free audio program I give away on - 5 Critical Tactics for Business Blog Success.
You can also get a physical version which includes a book and CD (more content) for $27.
Or you can get the Kindle version for $2.99.
You can get the content however you want. Each version is a little different in that you may get audio only, text only or both.
I do the same with my product How to Drive Quality Traffic to Your Blog. There is no free version of this one. You can get it digital (mp3, ebook + bonuses) or just the text on Kindle ($2.99). The physical version is produced but not available yet. I use Vervante to produce and fulfill orders of my physical products.
