After reading the help given in
this thread, I'm in a pretty good mood, so let's see.
If you can get your own domain name, do so, as it would be pretty wasteful to go around writing articles that link to the blogspot blog, if you decide you'd prefer a domain of your own further on down the road.
If you get your own domain, assuming you can afford hosting, get a wordpress blog up. From there,
this thread on wordpress and blogging should be useful.
Looking through the site/blog as you have it now,
this post looks like it would be the most useful. Since (the) RocketChinese (course?) is what you're trying to drive your visitors too, a review makes the most sense as being something that could serve as transitional content. With that in mind, I'd suggest getting it on the front page of your site and keeping it there. All of the other posts there would still be useful, but they'd serve better, instead, as extra topical content to feed interest.
By doing that, you begin to turn it into a review blog that happens to have other posts, rather than a blog that happens to have a review.
I'm not all that familiar w/ Clickbank just yet, but giving the visitors what most directly influences their decision is more of an unconditional tip.
Modify the review post to feel like a bit less of an obstacle to read too. You don't want first time visitors coming to your site, seeing a wall of text, and thinking "I don't know if I have the time to get to all this, maybe later" and forgetting about your site altogether. Compress some of the content and optimize your wording. Get some bold paragraph titles in there like you did
here, although the content there is a little intimidating too.
Anyway, start from there and if you come back, maybe you'll get some more help.
P.S. - Clickbank is just a network w/ digital products. It's not like this newbie is promoting "Make moneyz with ur ezbake".
