I agree with Dom as well, when you are new, submitting to the smaller engines is worthwhile. I also used to spend endless hours manually submitting to them.
Now I just blast out a press release to 4 or 5 sites. Mostly for my eBay store and retail web site. These get picked up by the RSS feeds and actually show up in Google rather quickly. They’re good for a spike in traffic, just got to make sure you have some decent keywords up front. I’m curious though, I wonder if Google crawls the links in them? Anyone know?
Cheers
