Select Distribution
I recently mentioned the Sigur Rós Hiema video, which was featured on the YouTube homepage for a day and probably got about a million pageviews. An SEO Book reader named Satish discovered that after the video built up a lot of viral media and link exposure the video was set to private mode.
Google video, as a DRM service, failed miserably. But providing custom hosting for member videos that can only be viewed from certain sites or for a certain number of views is an easy win for YouTube if/when they decide to do so. Google already owns Checkout, so it should be easy to do after they have the right relationships in place.
I predict that if that limited syndication model is available to the masses, a future media pricing system will allow publishers to offer free video for the first X views and then the videos are turned to private / members only / payment required after they get a certain number of views. All the free views build the perceived social value, while being easy to market since the content is originally free.
Sliding Price Scales Starting at Free
Seth talked about taxing latecomers by making events expensive at the end and cheaper for the first few people. And music is priced this way on Amie Street. It is basically the concept of Piracy is Progressive Taxation flipped on its head - make it free to build awareness until people really value it, then let the irrational herd follow along for the ride.
Word of Mouth is the Best Long-term Marketing Strategy
The free then paid model encourages the creation of remarkable content and ensures artists and authors are paid a fair market value for their best work. And it offers a profound business model strategy because as markets saturate marketing gets more expensive and attention gets more scarce - the easiest way to do marketing is just make it easy to use, consume, and share - and rely on word of mouth to do the marketing. And it is far better than monetizing via advertising because it is more organic, and stems from the web's strengths. As Jakob Nielsen said:
"The basic point about the web is that it is not an advertising medium. The web is not a selling medium; it is a buying medium. It is user-controlled, so the user controls, the user experiences."
When there is an unlimited amount of competition consumers are far more likely to buy what is already well trusted amongst the community.
This Type of Technology is Easy to do
The cool thing about my current content management system set-up is I can control permissions for any article on this site. It could even be automated for certain classes of information (ie: only pages, only blog posts, only book pages, only on newsletters, only on a subdomain, sitewide, etc.) ... it is entirely flexible.
Limitations
You wouldn't want to bait and switch everything you did or you would build up some serious negative karma and some people may not be willing to link at you, but most people will not care or notice. The attention comes and goes, but the links stick. If you turned 10% to 30% of your well loved featured content into premium content I doubt it would hurt your link building much, although your rear end might get sore from your wallet filling up with cash. :)
