Directory submissions are essential and one of the first steps taken for marketing. Lot of us do so to increase our back-links, followed by page rank and traffic. How many directory submissions are considered optimum? Is there a bar on that? Some people suggest too much ain't good, then chances are there being blacklisted.
Tea breaks, coffee breaks, sex sessions (longer than breaks) are all allowed and encouraged Just had a reality check and need to add some more here the order is:- Sex sessions first followed by submissions etc etc
nobody knows the thresholds of the different search engines but in my opinion there is no "too much quality links". The keyword here is quality. as long as you pick quality links you can submit as much as you afford.
directory submissions, both paid and free ones should be done regularly! 10 submission a day is good, just keep doing it everyday!
Its really not easy getting top of the hill. I did submit to some very good directories like yahoo, aviva, alive, dirspace, dreamdirectory,v7n,linksjuice,casacandra,romow,2yi. And also several hundred free ones in last one month. I used to have linkexchange with about 550 websites. Now I stopped it. If google see the sudden rise of all the oneway PR6,7,8 links, what they will do? Should I breathe and live with dir submissions.
