blog traffic and adsense issue

I am running a blog http://www.rizztourandtravels.com ​from last 4 years. But not getting good traffic. I want to earn money. Also adsense is approved for this domain. From last 3 or 4 months not getting 100 % earing. I am only getting 2 % of it, other all are deducted as invalid traffic.

Understand your ad traffic and site visitors.
Avoid partnering with untrusted / low-quality parties.
Don't click on your own ads, even if you think it's okay to do so.
Double- and triple-check your implementation.
Consult the AdSense Help Forum.
