Directory submission Service is the process of submitting your website’s link to web directories or internet directories. This process involves submitting a short description along with a suitable title. Both title and keywords should be keyword rich. The main aim of this strategy is to get High Quality Back Links for websites.
Manual submission is the best approach because your approval rate in the directories will be very poor when you make use of automated submissions.
It is not without reason web directories recommend that webmasters use manual submission services because automated submission tools are used extensively by people that spam the web. Using such tools spammers submit to multiple categories in the same directory and damaging the integrity of the web directories. So in an effort to keep spamming under control web directories do not easily approve submissions that are automated. So if your service provider makes use of automated submissions then you will not get your money’s worth.
You will get the maximum number of links possible from each package. Customers obviously like companies that give them the best value for the money they spend.
