Why i only got one external link?

I login to my google webmaster tool.
my site have 5 month history and the number of 1510 google result.
but external link only one result
internal link are the same one.

I have 2K post signaure at DP
but no any back links from DP?

 

I can't say why you have lost your backlinks as you do have some. Check allinurl:hotelpictures.adulu.com
But your site has almost zero content, i.e. text or words. Maybe it's been dropped because of that?

 

I checked your backlinks, you're already getting backlinks from your signature link, check with this tools; http://analyzebacklinks.com/

 

5 Month History is a long period for 1 link only, maybe you should wait for another month and let's see how it will goes.

 

The tool is interesting! good results
but it's not google tool.

 

You have to remember that google only shows a small portion of your
backlinks.

 

and be it that they are relevant small portion backlinks.
