It's not free but it is cost-effective but if you have more than one site, I'd recommend SliQ Submitter Plus.
Sliq submitter actually looks very well put together. That was probably one of the best recommendations you'll find.
Directory submissions are a waste of time, imo, Google has de-valued this type of links long time ago, SY
I am on their site right now. Never tried it, but can someone else report on it? There seems to be a free limited version and you pay extra for a full submission. There is another one called link assistant I am looking at right now. Lest I forget: Any known bugs, spyware issues with this softwares?
I've tried fastdirectorysubmitter, you can use just 150 directories for free and some of that will not accept your site... to get the full access you have to buy credits (seems about 20$)
I've used it only two days ago...but I don't think to see big results...I think that you can take little advantage from it just for new site...
Two days is a bit short notice for directory submission. I guess measurable results may pop up after two weeks or more.
