Buy Links from Directories – Unfortunately Google has penalized almost all the directories who were involved in link buying but still there are few trusted directories left. They are costly, but if you can afford it, than its worth going for Yahoo Directory(http://dir.yahoo.com/) for review fees of $300. BOTW (http://botw.org/) for $80 per year or $240/permanent. If you have a business site and have deep pockets than its worth going for Busness.com Directory http://www.business.com/directory/index.asp although don’t expect much traffic from it.
