Pagerank of 2 with zero SEO efforts

First of all here is the PR of my domain:

Good side:

The Pagerank update happened within a short-time frame of 10 months after registering mithunjj.com.

I have not done any link-building other than dropping my URL in some forums which I’m part of.  Also, I’m not a regular and consistent blogger when compared to others.

I’m now associating PR with domain trust and authority and it’s not a sure-shot sign that your site will rank higher than others in search engine results page (SERP).

Bad Side:

My site is not ranking for my primary keyword mithun john jacob in Google all the time because of a small misconfiguration(stupidity) of WordPress and robots.txt from my side. Seems to be like that Google is slapping me everyday(but not always!).

P.S: I’ve made up my mind to blog regularly and update the site with quality content(loved by both the readers and search engines!).
