Give me a Break.....

You have a nice site, focused on a niche-topic. But I find that the site is quite new. Not even six months old? I guess the domain is also not six months old? That might be an issue even though you seem to have a decent number of posts in there. Try to maintain a minimum word-count of 400-500 words in your posts (some of your posts seem to be slightly shorter) and try to write some pillar articles (in excess of 1200 words) occassionally that can bring in some decent traffic. Traffic is also an important metric they use while evaluating.

Also, next time when you apply, try removing those Infolinks ads while applying (temporarily). You can always add them back later on. But do think if these ads distract your readers, before adding them again. During the initial stages, your revenue won't be considerable. So, don't worry too much about monetization right now. Focus more on user experience/traffic. Add an email subscription option to your blog (you can use feedburner.com for that).

I am no expert, but these are my suggestions.

Destination,

you call yourself not an expert but your inputs have given me info that i am looking for... email subscription...that makes more sense.

Is there a way reader automatically gets to know when a comment has been added to the article that he has earlier commented.

I will work on your inputs. Thanks for your suggestions

shashank,

I am aware that ad income is very low. it can now where match the time i am spending on it. Now it has kind of become an issue that is challenging me. Probably the day i get approval i may never use it...  Yes i agree my blog is just 5 months old and i just add 2 articles per week. It is just my personal write up.:)

For passive income probably there other ways better than blogging. Blogging takes away lots of time and generates less money.
