I'm working on my new site and want to get good rank and traffic. What do you prefer most effective Blog Commenting or Social Bookmarking Submission ? Thanks
Why can't you do both? I personally do it the old-school way and comment, even though I realise that Social Bookmarking might be more effective.
I agree that you should do both. Bookmarking a new blog post takes very little time. When you blog comment be sure that you are leaving comments that add to the conversation by making a new point, asking a question, adding further input etc. Spammy comments won't get you anywhere. The point of commenting on a blog is to participate in the community which will expose you to more people and help you develop relationships. Do not blog comment simply in an attempt to build links.
