There are many things by which you could get your approved adsense to be get blocked.So here i will share some of my experiences with you regarding this.
Content size:
The page or the post which you are putting must be atleast a bit longer with minimum of 200 words.Because when you put a small post and a lot of ads,adsense will think,you are making them fool and trying to get more clicks on fake content.
Other ads:
Don't ever put other ads in your site while using adsense.Chitika will prompt you.But adsense will not agree with that.No popups,keyword ads,link ads.But banner exchange with other sites is possible.But remember adsense is a google product.It has enough power to analyse it.
No redirection:
DO not make your blog or site to redirect to another site.Adsense will take it a fake method from you to increase page views.Also Don't create re-directions from other sites or blogs to your adsense using site,even it is from a purchased domain forwarding.But you can instead use backlinks,and only from similar niched sites.
blombing:
This is a new word which is shortened from blogging and m\bombing.This means there re many effective but false methods to give a server load to blogs.Adding a lot of same keywords in almost all pages,getting a lot of backlinks from backlink bombing sites like pingbomb,getting a huge visitors from freehit sites etc...
Self clicking;
Never self click on your ads.Because the ip address,machine address,location and everything of your login are recorded by adsense bots.They will even look for the distance between the regular login location to ad clicking location.Also they will have a record on what,did the clicker browsed for last three pages.So direct ad click is always prohibited.Instead increase SEO and get visitors from search engines.
Boasting:
Avoid boasting about your blog in the social media.Because through click bombing,it is easy for a person to block your account.So remember,donot either disclose your blog id to your friends or never make a craze bet
