Once you have a trusted brand you can create low value white label brands that are given a free pass by search engine editors based on the trust of your core brand. These can feed back profits to your main site in many ways, including allowing you to:

• filter link juice to your mother brand site, which is especially useful for temporal news or in categories where link building is tough

• create additional ad inventory that sells at the premium CPM rate of your core brand (see also: Extending the Reach / Circulation of a Web Based Content Site & Ad Network)
• extend to new markets without requiring you to risk tarnishing your main brand

There are many ways to extend, including

• subdomains (eBay is the master of subdomains)

• related brand sites (US News & World Report launched RankingsAndReviews.com, which touches virtually every high paying category)
• editorial channels tracking the marketplace of your main brand (Yahoo! Buzz published a blog post titled “About That Ringtone“)
• sites owned by fake affiliates that you claim no ownership of (use affiliate software to track your sister sites and remove blame from your company)
