Hi, Each property is pointing your site and to a further property page. Each Article is carrying 2 Keywords as anchor text with do follow tag. The Posts are linked in a closed round-trip path so that your site gets one backlink from each property. So I will create a big high Domains PR 6~8 Wheel for you , it will be very helpful for your keywords! Way better than the one way seo coz these are pointing to each others and have 3000 pings.
