Since discovering the WF and spending some time here, I've gotten some fantastic tips and techniques and resources, as well as having received answers to questions on my mind... so in good WF fashion, I want to give back.
Here's a simple but effective little strategy I use for backlinking and site promotion - granted this is not an earth-shattering mind-blowing technique, but it's been working well for me and gotten me traffic and assisted with ranking & SEO.
This also keeps me up to date on my area of interest - that's another benefit of this strategy.
First, I set up Google Alerts for the keywords on my site. This is astoundingly quick and easy, if you haven't done it before, it's a total breeze. Sign into your Google account and set up your alerts here: Google Alerts
I set my alerts for daily notification rather than as they happen.
When my alerts come in via email, I click each link and open up a new tab in my browser - if you hold down the CTRL key while clicking, that'll open new tabs.
Next I scan each of them quickly, first scan is just to see what the overall content is and typically it'll be a Google News alert or a blog post, so I look to see if there's a comment function - typically they're asking for name, email, URL, and comment, so for my name I also put my keyword in there in a logical natural way. If I have to sign in or create a membership, I'll usually skip it. I make a brief but relevant comment contributing to the conversation or relevant to the blog post or article also with my keywords.
In one case, I got a huge backlink from some media outlet page when I posted a comment in response to one of their articles. The higher authority/page rank the site/page has, the "huger" the link ;-)
I have 4 Google alerts set up for my keywords and my total time invested per day is literally 10 or 15 minutes tops.
Sure, I realize that some commenting is going on no-follow sites, but so what? If I get a do-follow backlink that's great, but I also get exposure and people do visit my site after reading my comments - not every time/all the time, but enough of the time to make it worth it.
So, this strategy gets me some relevant backlinks, relevant exposure, and keeps me up to date on what's happening (at least on Google) for my keywords.
I hope this is helpful to someone! ;-)
