Just started a blogger blog. Any advice?

Just started a Blogger blog.
Here I have made two posts, one explaining what jail breaking is and another highlighting the pros and cons of jail breaking.
I have enabled monetization through Adsense and have a few ads running.
Can anyone give me any tips on how to improve this blog? I will be adding more content to the blog so that should surely increase the page rank and related keywords.
How do I get better, higher value ads? Also how can I get more traffic to my blog?
How do I add keywords to the page, etc?

Cheers guys, really appreciate it.
Abz.

P.S. sorry about the newbie-ness because that what I am.

Don't be sorry about your newbie ness. We all start somewhere. Blogging can be tedious and many give it up after awhile, but something that I have learned going through the process is that you want to fill your content as richly as possible. Don't worry about keyword density, giving genuine information will help you attract the visitors better than anything else.

Then I would recommend doing SEO on a few of your posts. That you know people are seeking the information on.

At the moment you should focus only on your content. At least have 15 - 20 articles closely related to your niche. Once you've the content in place, you can focus on SEO, optimizing your article keywords etc. Only good traffic and quality content helps you in fetching the high value ads.
As the other poster said, blogging is not for everyone and many give up soon. So try to enjoy the art of writing and keep writing. Don't give up too early. Good luck.

I just want to suggest you that Blogger is too much strict these days. So you have to be so much careful and you also should avoid doing any kind of things which are prohibited by Google's TOS. So read the TOS before you start working.Putting cheat codes have some rules. You have to learn these.
