I am a big fan of Google and its incredible usefulness. Google is my
homepage! With that, one of our sites has been listed on Google for a
while: http://www.depressionremedy.com. I had only submitted the
homepage knowing that the robot will spider all of the pages. 
However, when I use the "backward links" option
(link:http://www.depressionremedy.com/) I get this message: "Your
search - link:http://www.depressionremedy.com/ - did not match any
documents."  In other words, none of the internal or external links
are listed. I tried many other sites and found all of their internal
and external sites listed on Google.

Why?  Do I need to submit each page to Google?  Anything wrong with
the links on the above site?

Hi there,

Be assured that the other pages of your site have been indexed by
Google:
://www.google.com/search?hl=en&lr=&ie=UTF-8&newwindow=1&safe=off&q=+site:www.depressionremedy.com+depressionremedy

I have come across this problem before. A site has links to it, and
each party has been indexed by Google, but the backward links option
shows no results.

At WebmasterWorld I found a brief discussion on this matter, and
someone suggests that no links will show if the site has a Page Rank
of less than 4:
http://www.webmasterworld.com/forum12/452.htm

I tested this on a few sites with a Page Rank of 3 and some had the
same problem as your site, whereas others had backward links
displayed. So I have no idea why this is.

Dear benmar-ga,

Are you listed with Dmoz.org ?
I think no.
Unless untill you are listed in Domz.org you will get this message: "Your 
search - link:http://www.depressionremedy.com/ - did not match any 
documents." 

Once you are listed their,your links will be shown.
This does not mean that your links are not exsistant.It simply
does not show unless untill your website appear in index of
Domz.org.
Try listing with Dmoz.org.

Rajesh, there a number of sites which are not on dmoz which have backward links

I'm sure it's a glich.
I had a time when all backward links disappeared, during which I was
panicking in case we'd been penalised (for WHAT? I wailed).   Then
they re-appeared, stronger than ever, after a few weeks.
My problem is how to get listed on DMOZ, as we've got a highly ethical
site with good Google rankings, but we just get ignored - three
submissions in the past nine months ...

Is the glitch on our site or with Google indexing process?  Do you
think the robot is going out to other member sites before indexing the
whole site?  I am wondering if I should take out the links to all of
the other member site to assure deep crawl.  Any thoughts or comments?

Thanks

I too have had the same problem. My sites
(http://john-mason.shackelford.org, http://shackelford.org have been
listed on Google for years now but the link: search has always
produced zero results though I can confirm that other sites (including
DMOZ) that link to them are in Google's cache. I'd be happy to add my
own Q with $ to anyone that can help correct this. I want my site to
be search friendly and If I am doing something wrong I'd like to know
about it.

The 'link:' operator only traces sites outside of
your site which have links pointing to your site.
It does not show the links within your site which 
point to other pages in your site, or to pages 
outside your site.

"Some words, when followed by a colon, have special
 meanings to Google. One such word for Google is the
 link: operator. The query link:siteURL  shows you
 all the pages that point to that URL. For example,
 link:www.google.com will show you all the pages that
 point to Google's home page. You cannot combine a
 link: search with a regular keyword search"
://www.google.com/help/features.html

A better tool to use to show the various pages which
Google recognizes on your site, is the 'Site search',
which is also described on the Google page above.

If you type in an 'un'common word, likely to be found
on many of the pages at your site, such as 'depression',
it will look like this:  
"depression site:www.depressionremedy.com"
which returns this page of 'hits', with 18 of 87
results listed:
://www.google.com/search?num=50&hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&q=depression+site%3Awww.depressionremedy.com

This shows that your site has been well digested
by Google's 'spider'. If you search for other terms,
pages which don't have the word 'depression' on them
will show up, as well. Unfortunately, you cannot use
'common' terms, like 'the', which would show up on 
every page of your site, thus giving you the complete
picture.

A better tool to see which outside sites have links
which point to your site, is the LinkPopularity.com 
website, which determines the number of links referring 
to your website from other websites. The LinkPopularity 
site is here: 
http://www.linkpopularity.com/ 

Entering your site produces this page:
http://www.linkpopularity.com/linkpop.cgi?url=http%3A%2F%2Fwww.depressionremedy.com&ref=&a=1&name.x=59&name.y=31
which indicates that AltaVista found 7 outside links
to your site, and HotBot found 9. Google, however,
found none, and, like the other commenters, I really
don't know why.
