Just checked analytics and Top directory referring me traffic sent me 60 visits over the last 30 days. The next directory sent 32 and third place sent 19. AND NO - none of those directories are Free..... Of course this does not take into account any effect they have on search engine traffic in addition to that.
I am getting good traffic from free directories. Directory submission always help me in SEO and traffic
I don't get traffic from directory and I never expect to get traffic from directory just need backlink from it.
Dudes are right.. Do not wait traffic because those services are used for backlinks.. Necessary for Google indexing.
