I am developing a back link tool for Chinese SEO (our web site URL is:

http://link.aizhan.com just like ahrefs.com.

I encountered a problem which is how to handle multiple pages of the same site with the same out links.

For example:

Most pages of bbs.chinaz.com have the same out links such as:

 bbs.chinaz.com/Tea/thread-6293993-1-1.html
 bbs.chinaz.com/Tea/list-1.html
 bbs.chinaz.com/alimama/thread-6265032-1-1.html
 bbs.chinaz.com/alimama/thread-6265032-2-1.html?userid=-1&extParms=
 bbs.chinaz.com/Shuiba/list-1.html
 bbs.chinaz.com/FeedBack/thread-4456753-1-1.html

etc..

All of the pages have the same out links in the top of the page:

www.cnzz.com(anchor text:免费统计) 
www.313.com(建站大师) 
www.idc123.com（主机之家） 

Suppose I store these outlinks into database. The SEO will find there are six backlinks from bbs.chinaz.com of www.cnzz.com. This is obviously no sense for the SEO.

Can you tell me how do you deal with this problem?
