Do you know how much your blog is actually worth? In case you haven't tried it, there's a fun widget available at Dane Carlson's Business Opportunities Blog that will tell you.
Simply type your blog's URL into the field provided, and your blog's worth is automatically calculated and provided to you along with code you can copy and paste into your blog's template to display a fun icon on your blog that says, "My blog is worth $XXXX. How much is your worth?" Of course, a link is provided so people can check the worth of their own blogs.
Keep in mind, while this tool uses information from Technorati, including incoming links and more to value your blog, it's practically impossible that you could ever sell your blog for the amount given or set advertising rates based on that amount. For example, my personal blog is valued at nearly $105,000, but there is no way anyone would ever pay me that much for it. The Blog Worth Calculator is fun, but don't rely on it to set any kind of business-related goals.
Have you calculated your blog's worth? If not, follow the link and give it a try!
