We have higher expectations than most for SEO friendly. Specifically, we ensure that the general directories that we choose:
1.pass PageRank (links are dofollow and are not redirected).
2.have at least 50 pages indexed by Google.
3.are not penalized by Google.
4.do not belong to a large network of sites hosted on the same IP. We do not submit to more than one directory from the same IP.
