Forums. article marketing, forum profiles, directory submissions, blog comments are the usual seo people do for new and old sites.
But i want to make sure you are all using question and answer websites.
The reason being:
- Content is relevant to the backlinks
- High page rank sites
- Lots of traffic
- People using question and answers websites can't find their answers on google
- Once your link is on the site it lasts and brings a constant flow of traffic

These are question and answer websites i found that are general niches. So there should be something for everybody to get you all started!
A good bet would be to search a question. and see if it ranks high in google. try answer it.. and your link will be ranked high!
