How to Use AdSense?First of all, of course, you need to have a good website (a blog is also a website!) with good quality content available on it. If you already have a website, you can apply to get AdSense approval from Google. Upon receiving your application, Google's automatic software will visit your website to see if it meets the criteria mentioned in the Google's AdSense policy. Following are some of the points you need to keep in mind before applying for AdSense approval (these advices are based of Google's policies):
Your website must be a top-level domain. That is to say that the address of the website that you are submitting for approval should look like www.example.com or johndoe.example.com. A website URL like www.example.com/johndoe will be rejected by AdSense Language of the content on your website should be in the list of supported languages. Every languages is not supported by Google AdSense. For example, currently, English is supported but Tamil is not. (update on 10 December 2014: Hindi is now being supported by Google AdSense)
Website should have a decent amount of content. It should not be freshly made (a website running for a few months will make the cut)
Website content must not be copied from somewhere else on Internet. Google can detect plagiarism and will reject your application.Website must not have pornographic material on it.
In case Google rejects your application, you can resubmit the application after resolving the issue cited in the rejection email you'll receive. Try to resolve all the issues before resubmission because repeated resubmission could get your AdSense account blocked.
A few more important things that you need to know while setting up your Google AdSense account.
Remember, Google is fussy about changing your country if you later on want to change your address. I had an AdSense account approved when I used to live in the UK. Unsuspectingly, I had given my UK address to get the payment from Google. Later on when I moved to India and I tried to change my address from UK to India -Google refused to do so. Google AdSense, at present, does not change address with the new address located in certain countries. So, be careful about it. In such a case you'll have to create a new account.
You'll get the payment through bank transfer from Google only after you have accumulated at least $100 in your account. You can not ask Google to pay you an amount less than $100 that you have in your account.
