I want to promote 5 sites in same niche. To save some budget i want to create web2.0 properties containing links to all 5 sites in the same time. Can it be possible footprint? Let say post article on wordpress property linking to all 5 sites... Or let say i found the quality niche related comments possibilties and i putting all five sites in comment. I understand that ideally i should create separate link/property/article/etc for each site - but budget/time/ROI wise it seems like not the best thing.
