Once, the submission tools were the webmaster's friends, but things have changed a little. The tools to help webmasters save time when submitting the URLs to multiple locations were greatly appreciated when they arrived, but abuse and overuse has depreciated those tools. Using submission tools today is risky, but some may prefer using them. The risk is that URL submissions might cause your Web site to be penalized or listings not accepted. Before using a submission tool a good advice might be to search for user review in the search engines or locate the most respected submission tool you can find, even though that tool might have the fewest search engines.
