Couple of things you should do
Wrtie more frequently. You have been blogging for 8-9 months but posts are infrequent. I suggest you to fix a frequency to post blogs and follow that frequency. Your blog would do well if you post on a daily basis.
Start commenting to blogs which are on same topic.
You can also use social media effectively to promote yourself especially twitter. A daily forecast tweet daily for sun signs.
Start publicising your predictions which were true in the past. This help you to build your credibility.
Predict about elections, IPL. I was reading somewhere astrology is Rs 600 crore business during elections.
And last but not the least predict IndiBlogger members future for free
and we will get you more customers
