I know how to figure out the number of backlinks on Yahoo and Google. My question is, how can I get the number of unique sites who give me backlinks. I can use the "linkdomain:site.com -site.com" but that will give me the number of backlinks, so if I have 1000 links from one domain they will all count.
From your google webmaster account download the links table. Run the domain extractor utility or any other document manager like K-Free And it will extract the domains from it. No repeats
