There is a couple of things happening here:
- Jennifer is providing a tutorial for her blog visitors
- Cultivating future clients for her mentor, photo workshops and tutorial services
- Giving back to the community who will spread the word that their is this business photography blog that you might want to check out.
One of the way that has worked for a lot of people is to build a credible space with information that people value. Let it be known that you are out there and folks who are interested will stop by.
There is another word for this concept; Freemium. These are a few examples of how the Freemium concept is applied:
- Om Malik How Freemium Can Work for Your Start Up
- Mail Chimp Going Freemium One Year Later
- The Rapportive Blog Will Freemium Right for You?
I do know that web video plays a role.
