Some customers are concerned about being penalized for getting too many links too fast and hence this feature. However, this fear may be unfounded as directory submissions anyway take between a week to a couple of months before being reviewed and approved. Therefore, even if an order for 900 submissions has been placed, it will take around 90 days before most of the submissions are reviewed and approved. Nonetheless, for those who prefer to play it safe, we offer the option to 'stagger' or 'spread out' the pace at which submissions are made to directories.
