How to remove sitewide links from Yahoo linkdomain:
If you want to find your back links you can go to www.yahoo.com and type in linkdomain:www.mysite.com. If somebody has put your link all of their pages or just several pages you can remove that from your linkdomain: search. What I will do is linkdomain:www.mysite.com -site:mysite.com -site:othersite1.com -site:othersite2.com Keep adding domains until you get rid of all the extra junk. I found I had to add -site:yahoo.com because my Yahoo directory link was put in quite a few different yahoo directories.
This also works the other way to only show links from one site or links that contain other words like type in “directory” to find all sites that link to you and have the word “directory” on them. You can play around with the other advanced searches like intitle: inurl:. I like to try linkdomain:www.mysite.com inurl:”edu” to see if I have in .edu links.
