"Blogs that are about specific topics generate traffic from people who are either really interested in the topic or doing research," says Jay Brewer, CEO of Blogpire (www.blogpire.com), which operates subject-specific blogs on topics such as shaving equipment and GPS receivers, in addition to the aforementioned single-serve coffee makers.
Some of the sites on blogpire have advertising and affiliate click through rates of up to ten percent, he says. Furthermore, the more specific the subject, the less competition it will face from other Web sites. A Google (NSDQ: GOOG) search for "dogs" yields about 278 million results. A Google search for "grooming products for Golden Retrievers" yields one result.
To bolster the revenue you receive from general advertising and affiliate programs, you can seek out individual advertisers whose products you might be featuring on your blog. While giant corporations aren't likely to advertise on your little Web site, their partners might. "Find the PR person's name and send them a note," Brewer says. "And don't dream too big. You don't have to have Philips or Sony (NYSE: SNE) as an advertiser. You can have an online site that sells products from Philips and Sony."
