1) Post More Often
A quick glance at your blog shows that you’ve only posted two entries in your blog over the past month. Google loves fresh content that is regularly updated. I would suggest to post at least once a week and continue in a regular pattern. In November and December you posted eight posts per month while in May you’ve only done one and we’re half way through the month.
2) Write 300 Words or More
Google wants to see that your posts have enough meat to them before they rank you in their index. You want to make sure that your posts are at least 300 words to show Google that it is a serious post and is worthy of their attention. Your most recent post is only 209 words while the one before it is only 176 words. Try to make a serious effort for future posts to get over the 300 word threshold.
3) Get More Links
This seems to be a recurring theme with many of the sites that have been submitted. Your Page Rank is only a 2 and you need to get a higher ranking if you want your pages to come up in Google’s index. Instead of spending your time commenting on other people’s blogs (blog comments are usually set to “nofollow” which means you get no Page Rank benefit from them), I would try to establish link relationships with those blogs, write in forums which do not have the “nofollow” on them, post articles in article directories, and write great content that people want to link to.
