I was wondering if I need to use blog commenting and forum posts in my strategy? I really do not want to, as they can be spammy as hell and may have a detrimental affect on my the authority of the sites they are linking to. I would like to avoid these altogether. How natural does it actually look anyway? As nowadays, who actually leaves a comment and a link to a site for any purpose other than seo. Surely the best natural backlinks are those linking from related content such as articles, blog posts and press releases.
