After you have exerted effort in optimizing your website and still need additional traffic you may want to use alternative sources. Below are some of the list that you can generate traffic.

1. Forums - community forums can be a great resource for your traffic. Members of these sites interact with each other that lead to referring of websites. Put your website’s url within your signature block so that other members can view your site. Just make it sure that the forums that you will be joining is related to your website’s topic.

2. Groups - both yahoo and google groups is another great source of traffic. Members interact with each other through email subscription. You can send a notice to the group members regarding your website or answer members query.

3. Article Submission - submit articles to different article directories like ezinearticles.com. If your article is approved by the admin, other members can use you content provided that your signature or copyright notice is attached at the end of the article. This is another great resource of link building. Be sure that the article that you are submitting is your original work otherwise you might be accused of copyright infringement.

4. RSS Feeds - this is one of the easy ways to get additional traffic specially if you are using wordpress. You just submit your rss feeds to different blog directories and wallahh, you just advertised your website.

5. Offer free ebooks and other stuff - one example is offering free web templates at opensourcedesign.com Just include your keyword/url at the footer of the template. In this way you can have more inbound link coming form the site that uses your template.

There are still a lot of ways to increase traffic (aside from the generic search (engine)). One just need to think creatively.

1. Youtube.com
2. Build squidoo lens.
3. Submitting Press Releases to prdirecories.
