I know my site is good because I get emails almost every day thanking me for the great info and content. But, for the life of me, I cannot get any backlinks. Well, I have a few - a very few considering my traffic and the quantity of good content that I have. And considering how well-liked my site is by my readers, I just don't understand why more people aren't backlinking to me.

As Chris said, don't use backlinks as a metric. Really it doesn't matter how many you have if your getting the traffic anyway.

Anyway, I need a BackLinking 101. Nothing I've tried really works. Twittering gets me hits but no links. I've tried writing to related sites and no one writes me back. Plus, there aren't that many sites like mine anyway...Anyway, I'm at a loss. I don't know how people do it...

- Submit articles to directories with links in your author area.
- Forum signatures (Great for indexing, not so much for ranking high.)
- Some social bookmarking sites. Google for "dofollow social bookmarking sites".
- Directory submission - but be careful. Temporary backlinks aren't good, so only submit to directories that look like they plan on being around for quite some time (not the default template with a generic logo). If the directory links to gambling, porn, drugs, etc. don't submit.

And most importantly, vary your backlink title tags, anchor text, and surrounding content. Don't do 1000 backlinks in a week all with your keyword as the anchor text.

Forum posting is one of the techniques that helps you get back links.. In order to do that, go to User CP then on the upper left portion you can see the 'edit signature'.. If its not there, the webmaster or the administrator doesn't approve you to have your link signature yet.. You can read the rules and guidelines to help you more..

Thank all for advice this topic is great

Article marketing will work and give good quality backlinks if you write articles on topics closely related to your site. You need not give away information on your website. But still you can write about something that you can freely give away.

You'll get tons of back links when you participate on these kind of techniques. These techniques fall under Off-Page Optimization:
- article submissions
- blog commenting
- classified ads
- directory submissions
- forum posting
- link exchange
- press release
- online groups
- social media and networking
- social bookmarking
