My domain name is www.tcms-sep.com. Actually this is around 6 months
old web site. Earlier google were showing all its backward links but
now for the last 2-3 months it is showing nothing but we know that
their are some web sites from where we are getting the links.

I do not know what's going on. we keep ourselves away from any kind of
spamming.

Please help me out.

Thanks

Hi there,

AlltheWeb has 52 external pages linking to your site, all of which are
your other sites:
http://www.alltheweb.com/search?q=%2Blink.all%3Ahttp%3A%2F%2Fwww.tcms-sep.com%2F+-site%3Atcms-sep.com&c=web&cs=utf-8&o=50&l=any&no=off&co=1

I found two other pages that used to link to your site:
://www.google.com/search?q=tcms-sep+%2b%22.com%22

The Google backward links function, despite what you would expect,
does not return every link to your site, if your site or those linking
to it have a PR of less than 4. Your case has a PR4 linking to a PR4,
so I would put it down to Google not counting the links as valid
because they are from your own sites.


Suggestion
----------

Google penalizes sites which have "substantially duplicate content"
://www.google.com/webmasters/guidelines.html 
 
The techniques Google use to look for duplicate content are obviously
not known to the general public, but my educated guess says they look
for:
 
- a group of sites that all link to each other 
- duplicate contact details (like your toll-free number) 
- duplicate legal disclaimers 
- using the same graphics 
- ownership details in WHOIS records 
- using the same web host 
 
I am unable to tell if Google has a problem with your different sites
or not. I do however suggest that you distance them from each other as
much as possible.

Best wishes,
