Trouble with technorati

Before I go on I must apologize for requesting help on something related more to technorati than wordpress. The technorati support isn’t replyijng to my mails so I thought the next best sopurce of help could be WP Support. SO here goes:

When I try searching the URL https://manukhanna.com in the blog directory, I face the following issues:

1. The second search result is https://manukhanna.com/uncategorized/blogger-to-wordpress/. When I click this link, I get a 404. I haven’t put the post the link refers to in the Uncategorized category, so where did Technorati get this link from? The 4th and 5th search results have a similar link.
2. The number of search results is only 5, whereas I have over 50 posts in my blog.
3. In my WordPress dashboard, the incoming links are from https://manukhanna.com/blog. I changed my blog URL to https://manukhanna.com about three weeks ago, how come the old links are still being showed?

Thanks in advance.
