So I have been testing out buying dropped domains for building backlinks. I buy domains that have PR, high DA and PA. Aged even better. I look at the backlinks point to the domain, looking to see if they will stick around. I buy the domain with Private registration. I buy hosting that will not leave a "foot print" AKA seo hosting. I build a site on it with wordpress, build out the site to make a it look as real as possible. Point my links----> to my Money site I build some backlinks to it with senuke, ping the site. Some of my money site will go from not being listed in Google to the top 3 pages with just one domain. There is one draw back about this is that the cost get high and it takes time building the sites. This is working for me, I just want to share this and see if others are doing this.
