Technorati is a blog directory.
Technorati also use a proprietary blog ranking system, which is useful for helping you to find useful blogs in your marketing sector. Why is this useful? Other than the benefits of learning and reading, you can also use a list of blogs in your sector as a target list for link building and public relations.
Additional benefits exist for you as blog owner, if you add your blog to Technorati. Adding your blog, or “claiming” your blog if it is already on there, is of benefit as you get to ensure the details are as you would like them. Of course the link to your blog is a follow link – which is kind of like a “thumbs up” sign to a search engine crawler.
To claim your blog you just need to create an account on Technorati, add your blog and submit a claim. You will then be given a unique claim code like this Q7759JM7D5M7 (this one is mine ;-)). You will need to write a new blog post and insert your code into the post so that Technorati can crawl and verify the code in your post – thus telling you are indeed the said author, of said blog.
