I try to find link to www.mynevadacorporation.com on google, but this
show up. Anyone know why?

Your search - link:NXswWB08MFsJ:www.mynevadacorporation.com/ - did not
match any documents.

Greetings, ncpweb!

We gets lots of questions from website owners wanting to know why the
links: search method won't show that any pages link to their website,
even though they KNOW for a fact that such pages exist -- or why the
link: command returns a lot fewer results than the number of pages
that they KNOW link to their site.
    
Because of Google's secrecy, it is not known for absolute certain, but
the general consensus among experienced webmasters who have
extensively studied Google's "backward links" function is that if a
URL has a Page Rank less than 4, the link: function will not work, and
that if it has a Page Rank of 4 or higher, the link: function will
only return pages with a Rank of 4 or higher:
     
From Senior Forum Member "Beachboy" at WebmasterWorld:       
"Your index page is PR3, Google won't show any inbound links unless
the page you're doing the query on is PR4 or greater."
http://www.webmasterworld.com/forum3/4784.htm?highlight=inbound+links+higher
       
From Senior Forum Member "Birdman" at WebmasterWorld:       
"It is thought that Google only shows backlinks from pages that have a
pr4 or higher."

The reason that you don't get any backward links from the link:
function is that your Page Rank is only 3.
 

However, there IS still a way for you to check your backward links.
When you input "www.mynevadacorporation.com" into the Google Search
Text box and click "Google Search", the following page appears:
---------------------------------------------------------
My Nevada Corporation - A Leader in Forming Nevada Corporation
> Hot Links. Why Nevada? Nevada vs. Delaware. Which Entity?
myNevadaCorporation? Testimonials. > Streaming Audio. Why Nevada?
myNevadaCorporation? WHY CALL NOW? ...
Description: Offering incorporation services, LLC formation, and
resident agent services.
Category: Regional > North America > ... > Incorporation Services

Google can show you the following information for this URL:

Show Google's cache of www.mynevadacorporation.com 
Find web pages that are similar to www.mynevadacorporation.com 
Find web pages that link to www.mynevadacorporation.com 
Find web pages that contain the term "www.mynevadacorporation.com"
---------------------------------------------------------

If you click on the "contain the term" hyperlink in the last line, you
will see that Google has indexed 43 pages which contain a reference to
your site:
://www.google.com/search?q=%22www.mynevadacorporation.com%22&num=100&filter=0

However, that number contains a considerable number of pages from your
own site. To remove those from the listing, use the Search Text
"www.mynevadacorporation.com" -site:mynevadacorporation.com
://www.google.com/search?q=%22%2Bwww.mynevadacorporation.%2Bcom%22+-site%3Amynevadacorporation.com&filter=0&num=20
and you will see 14 external pages which reference your site.

In addition, if you're not already aware of it, you can also check
backward links by using AllTheWeb ( http://www.alltheweb.com ).
http://www.alltheweb.com/urlinfo?q=www.mynevadacorporation.com

Because AllTheWeb indexes the web differently than Google, you may get
quite different results using this search. AllTheWeb shows 27 external
sites which reference your URL:
http://www.alltheweb.com/search?q=%2Blink.all%3Awww.mynevadacorporation.com+-site%3Amynevadacorporation.com
