I agree wit William.

Use a tracking link that filters out bots, fake clicks, spam, etc. The one I use allows me to ban ip addresses from click fraud.

Instead of wasting time trying to save AdSense, spend that time getting something that pays better.

if you are using wordpress look for safe adsense plugin, it prevents visitor's from the same ip address from click fraud

I think, You should google it.

Only use SEO content on your blog.
