First, going to Technorati website and register an account. After that, login, claim your blog. Fill your blog information. They will give a token code which is random string. Next, you need to published it on your blog/website content, whatever, make it visible on your rss feed because Technorati will finding that token on your RSS for confirm. Come to now, if they founded, it's success and they will automatic crawl your new blog posts everytime you have. If failed, try again. The only reason make it failed is they cannot find token code on your rss. Make sure you do correctly.
Keep in mind that once they've found the token in your blog, there is still also a manual approval that usually takes about a day. If you blog is complete junk, it will likely be rejected.
Very good explanation! I myself did register for technorati a year back and the process for getting included with them was fairly simple and quick... but I really wonder if it has provided any substantial benefit in terms of visibility or traffic! Regards, RightMan
