if you have applied for adsense with the same website more than 3 times By 4th time they wont approve.they will keep your website in to black list i guess.
You can create a News Website targeted and apply it would work fine with adsense and after you can us adsense in all your sites if sites dont violate the rules of AdSense thanks
What stated G in the e-mail? There must be the answer and from there you should know where to fix the problem!
keep applying and never give up google might get tired of rejecting and approve you some day. i heard of a guy applying 12 times and finaly got aproved
open a google account --> go to blogger --->make a blog--->ad adsense then u will have ur adsense account
Your site must be more than 6 months older(if you from china, pakistan, india) Your site should be unique content. Create some good backlinks for your site Your site should be indexed by google (should be more than 100 pages)
