I was signing up for a Photobucket account the other day, and I was quite surprised by their aggresive attempt to monetize new signups. On the registration screen, you are asked to provide your cell phone number. If you enter your cell phone number, a pre-checked bx appears which reads “Yes, I would like my chance to win a new HDTV or a $500 Starbucks gift card and other great prizes from Bid4Prizes.”

Some of the details of the .cm domain name monetization scheme have been revealed since my last post on .cm domain names.  Business 2.0 ran a great article about what is going on with the .cm domain space. In my initial post, I detailed how nearly all .cm domain names were being redirected to a landing page on agoga.com that features ppc links from yahoo. The redirects and landing pages are managed by uber-domainer Kevin Ham. He has worked out an agreement with the government of Cameroon to share the revenues derived from the landing pages.

Social Networking site Tagged is going through explosive growth, and they have  an interesting growth and monetization strategy. Last week, a techcrunch profile mentioned that they are signing up 350,000 new users per day and generating 1 billion page views per month.  The site’s monthly revenue is $600k per month.

The first thing that sparked my interest was how on earth they could maintain such a rapid rate of new user acquisition.  During their signup process, they slyly ask users to import their address book to invite friends to the site. The friend invitations are some of the slickest that I have seen.  You can see some screenshots and a full writeup of the process here. I have read that they send out the invite multiple times. Apparently, this strategy has been very effective for them.
