no. It's a waste of time. Get a couple good links to a site and the search engines will crawl you right away.
I don't know... I'd say that it seems that for all of the links that I've submitted, about 1 in 10 show up in Yahoo or MSN... none on Google. Don't know how many of the submission sites added me or not... but, over time hopefully they will add up.. Probably not as immediate as link-building, but probably needs to be done too.
I think he means submission to search engines! IMO it is useless... Submit a site map to Google, yahoo and get couple of good links... and if you mean directory submissions then yes its also considered as link building and its worth if submitted to good directories. Cheers!
lol, I think that you might be right Alvin... if that's the case, I wouldn't worry, the search engines will find you...
