Here are some ways to check backlink profiles using major search engines:
• Yahoo! links – search for link:seobook.com to find links to that specific
page via Yahoo! Site Explorer http://siteexplorer.search.yahoo.com/
Site Explorer also allows you to filter out internal backlinks to be able to
get a better view of external inbound links
• Yahoo! Site links – shows links pointing to any page on a site. Uses the
same structure as above, but use linkdomain: instead of link:
• Yahoo! .edu links – links from .edu and .gov type websites may be trusted
more than typical links. You can view the .edu links pointing at
SeoBook.com using this link
http://search.yahoo.com/search?p=linkdomain:www.seobook.com%20%2Bsite:.edu%20-site:.com%20-site:www.seobook.com
• Google backlink check – use link:seobook.com, but please note that
Google only shows a small sample of the links they know of.
• Google similar pages check - related:http://www.seobook.com/ shows
sites which Google thinks are related to SEO Book.
• Google Blogseach Backlinks – Google’s Blogsearch will show you recent
links from blogs to any page on a particular site. On
http://blogsearch.google.com/ use link:seobook.com

Technorati – shows blog links similarly to how Google Blogsearch does.
Search at http://www.technorati.com for www.seobook.com
• Microsoft offers similar link functions as Yahoo!. Like Yahoo!, Microsoft
tends to show a larger and more comprehensive sample of linkage data
than Google.
• MSN reciprocal link checking feature. Microsoft allows you to see which
sites a domain links at using LinkFromDomain:seobook.com
By searching for links that are both to and from a domain you can see
which links are reciprocal links in nature and help further identify the local
topical community
