You will find a number of high quality links at the blog directories
. These blogs are free from spam and they have been actively existing for a long period. The blogs have attractive designs and they even allow the users to mingle and vote on each other's sites. The sites are well established and some have the control over numbers of backlinks from different websites. It would be impossible to have so many links without anything important to give to the internet community.A good directory will always have submission rules as it shows that their editorial policies are strict. Avoid any site that has no submission rule as they carry a lot of spam.
