For this reason directory editors review hundreds of sites per day and accept only those complying to a very strict set of guidelines. More than 90% of submissions are rejected, in many case without even the need to visit the site simply because of a poorly written submission.

Time consuming:
Directory submission is more difficult - and takes longer. Just as most professional webmasters do, so should you. They hire professionals that have experience in a particular topic or service, such as directory submission, and pay them a flat rate to accomplish such a service.

Especially when you start your business afresh and you take it as part time business , in that case you can not afford two things : wasting your time for such a time consuming jobs when you have a better option and doing anything impoperly.
