I found this site... now only a 30 day trial if free..... but submission is faster than doing them manually. http://myeasysubmitter.com/?xredirect=1
I like manually submitting by googling "search engines" but ALOT of copy & paste....
I did do a free massive submission for www.candybarwrap.com
Found that the majority send to smaller & less known search engines & be ready for a ton of verifying emails! Also some on going newsletters & advertisings. I just unsubscribe to most of the ads & any other junk.
I guess it can't hurt.
