I love to find out Belajar SEO's visitor site look like and the way I show my appreciation is by visiting their site. Let me show you an example, from my sidebar right now I saw Gudanglagu.com was on recent visitor Myblog Log.
So I will click the picture inside the Belajar SEO's widget, this will bring me to Mybloglog account. I will find out how many site do you put there and choose the suitable site that fit with me(if you have more than one site).
Then, I will enter your site and find the recent post from you. If your recent post is about something that I can't give suitable comment then I will find your popular post or other post that I can participate with comment.
Do you want me to do that? I think this can improve my traffic as I had a time to visiting my visitor site. So, if you want me actively participate in your blog, do visit here often and when I saw your name on Belajar SEO's widget recent visitor, I will visit you back!.
