How can i build links?

URL to my portal: www.us.adslog.com

Thank you for any advice.

 

for building links you simply need to submit the articles and get quality backlinks.

 

Where do you submit them? Do you have good results in SEO?

 

First article directories can help with link building, next do some guest posting on other site and use link carnivals sites..Just Google that...then people will naturally start to link to you.

 

Do you have some article directories list? Or carnivals sites?
Does smbd use Xrummer or Senuke for link building?
