Technorati Indexing FAQ
I claimed my blog. Why don't my posts show up on Technorati?
Not all claimed blogs are automatically included in Technorati's main search data set. Until a claimed blog is qualified into our main data set, it will be included in the Technorati Blog Directory and the blog listing from Tag pages, but we will not collect individual posts from that site and so the site content will not appear in our search results and links will not contribute to Technorati Authority. We are constantly reviewing new blogs for inclusion in our main data set.
Technorati does have posts from my site, but is not updating with new posts
If we do show posts from your site but are not updating properly with new information, it probably means that our crawler is having trouble reading your information. This could be a software or hardware failure on our side. It can also be caused by many of the same things that interfere with blog claiming -- please take a look at the points listed on Blog Claiming FAQ. Have you changed anything about your site setup or configuration recently?
