Previously, I have been discussing how to register your blog on google. This is almost the same as google search engine, but by registering your blog on google blog search, blog search will become more specific. Because google blog search is a search engine specifically made by google to search a blog.
Please visit http://blogsearch.google.com to look further. When you do a search on google, and did not find the keyword you're searching, then google will suggest you to perform searches more specific, ie special searching blogs.
To do register your blog, please visit http://blogsearch.google.com/ping, then enter the url of your blog there.
Hopefully useful and can help you increase your blog traffic.
