1. Backlinks Checker Tool - Backlink Watch
2. Site Explorer - Yahoo! Site Explorer
For me, backlinkwatch.com is saying "Out of Yahoo quota for today. Total 50,000 queries executed already." so I'll tell you my stats for my website learnthatlanguagenow.com that Yahoo reports.
Yahoo says for my site (learnthatlanguagenow.com) I have 3,431 inlinks and I set it to show inlinks for "except from this domain" and to "entire site".
What about your site? How many backlinks (inlinks) do you have?
