I use a variety of methods when promoting sites, but one area I've never really explored is blog commenting. I'm interested in it but would like to know if it has worked or what are the results of it.
Links are always good but its always the ROI and Google knows the Blog comments links are easily getable and so the amount of benefit you may get may not be worth working on it. After saying it does not mean when you read something interesting you should not comment with a link but then the aim should not be linking but commenting
