Other ways to promote your blog.

Promoting your blog yourself is an additional way to make money and can be faster. Some ways to promote your blog: Tell your friends about it. On any and every message board or community website you post at, put it in your signature. Put it in your e-mail signature. Leave comments on other blogs, either at Blogger Party or elsewhere, with a link back to your blog. Don't spam, though. Nobody likes spam. Ping your blog. While Blogger Party does this, you can still do it for your individual blog. Use http://bloggerparty.com/blog/ as the URL. Add your blog to blog directories.

Refer others for even more money.
The follwing extract i copied from the Userguide of this blog itself. I found it interesting. All of us may not pay attention. So just to memorise once again i permit myself to repeat this. I have found it very useful to understand better

You can now refer others to BloggerParty! Any time you refer someone and they register at the site, your ads will be displayed on their blogs 25% of the time. They lose nothing for using you a referrer, though. Their ads will still be displayed 50%. You get 25%, they get 50%, and BloggerParty gets 25%.

To refer others, use your referral link. To see what you referral link is, go to "my account" and look under the "Referrals" section.

This has the potential to be a HUGE jump in your earnings. You can refer as many people as you'd like. Good luck and happy blogging!
