I read few reviews on BlogExplosion and all of them highly recommend it to increase blog site traffic. So, I tried it, too.
The concept is simple, “You read other blog sites and they in return visit your blog.” After free registeration as member, you start to surf other members’ blog site to earn credits. The more credits the higher traffic you get.
It is good if you often spending time on reading strangers blog entries. For me, I would like to read a more specific topic sites, e.g. computer related. However, the blogs are randomly selected. You have no control at all.
Though there is a blog directory, but you do not earn credit by reading the blog of your choice.
I think, I will use BlogExplosion alot, if and only if it allows me to choose interested topics and then show me the related blogs.
Tips: To increase traffic, try to submit your blog site to web directories and search engines, pinging to blog farm, and update frequently.
