I ever asked Google to give me chance using google adsense at my blog and get refused. I don't know the reason because they don't give me at all. What should I do if I want to re-apply for the google adsense for the same blog or do I need to create a new blog?
You don't have to create a new blog, just try to make your blog unique and post quality content and i am sure you will get approved. If you had posted a link it would be easier to check what you did wrong.
Well, this day to get approve by Google has been hard but some people find it easy to be approve. First thing is to make sure that your site age is up to six month, let your home page has original content, use blogger.com to design the site(this make the approval faster)
Do continuous updation of your blog till Six month with a quality content, manage your blog with good designing & Gadgets, then reapply for Adsense. It will surely approved.
