The approval time of most directories takes a week to 4 months. If you want to get approved immediately, be ready to pay for it.

Many free directories take long time to approve or reject links, whereas most pay-for-review directories approve or reject links within 24 or 48 hours of submission. Free directories get overwhelmed with submissions. Imagine when a single directory gets over 50 submissions a day and the editors have to work several hours everyday to review links they are not paid to review. So, they do it only when they have spare time.

Many free directories are set up as something on the side. The owners have to devote their time on their main businesses that fetch them money. If you cannot pay for review, you need to have the patience to wait. The saying, "you get what you pay for" comes into play here.

Another thing is to look at the pending links before submitting. This is assuming the directory in question has site statistics. This will help you to calculate how long approximately you have to wait. It is counter-productive to submit your site to a directory that has several thousands of pending links. Such directories are not looked after and probably not well promoted.

As what I have experienced, in my own software, it can be submitted for a maximum of 100 to 150 directories.

But it depend on Directories admin. Generally most of directories taking too much time to approve So just submit you website to 1000s & more directories & waiting for backlinks
