Re my new osCommerce site

[ise]

I am very new to this,I have just instaled the Search Status in my task bar in my FF browser,and this is what it came up with for my new site,and I have no idea what it all means?

 

Show robots.txt

A) The requested document was not found on the server.

 

Q) Is this important,should I do something about it if so what?

 

 

Show index pages

 

google= ALL

 

Yahoo = None

 

msn= First Page only

 

Should I do something about it?

 

Page Rank= 0/10 but there is a small red pip on the page rank,that was not there yesterday,what does this mean.

 

 

Show back Links.......

 

Google= None

 

Yahoo = 50+

 

MSN =22

 

Sorry to as so many questions,

 

Thank you
