I love this technique because it is very simple and if you know me, I like simple.
First of all, why do you want more quality backlinks to your blog or site? Traffic!!!
An important SEO technique is having backlinks to your blog. The more you have, the more traffic you get and the higher your Google pagerank becomes. Comment marketing not only gives you a one-way backlink to your site but it is highly targeted that you have full control of. You get to choose where your comments go. So don’t just comment on any old site. Choose sites like your niche. A good way to choose sites is to search for top blogs within your niche; ie. “top <niche> blog”
