Google webmaster tool and yahoo site explorer says it has no backlinks. But it's absolutely impossibile. Do you think I had a penalization?

 

Where are you looking that you see zero?

I see you have 843 back links in Yahoo site explorer.

 

try this tool:

http://www.backlinkwatch.com/

 

use this operator in yahoo search link:your site url and you will be able to see your backlink.. You can also check the backlink from Google webmaster tool.

 

how did you search? brad above looks like did a search and found your links so they seem to be there

 

have you build any links towards that link?

 

I only use Google and Yahoo yahoo tool isw good it show each back link but google only showing some of quality back link, Use google I can also see you have back link

 

yahoo site explorer and other tools shows back-links for your site don't panic.different tools uses different word for back links like inbound links,inlinks.

 

It may be possible that you have posted any articles related to this link so you are not getting backlinks for this page URL..

 

thanks to all...maybe I've made some mistake when checking them
