Follow these steps:
Just create a new post including your claim token anywhere on the post content. Then publish the post.
Now sign in to your Technorati account and click on “Check Claim”, you may found it under the profile page.
This post also is the post I created to verify my blog on Technorati.com. Check your inbox.
After a few minutes you should receive an email saying something like this:
Thank you for submitting your blog claim on Technorati. We have successfully crawled your blog and found the claim token, and your claim is now awaiting review.
You can also publish a temporary post and the body of the post containing your claim token (KXVXXXXQXXXX for example). This post will be public facing but you’ll be able to remove it in a few minutes.
