1. Write original and high quality blog posts.Before even thinking about monetizing your blog, make sure that you have at least 10 original and high quality blog posts.
Each post should have at least 400 words each and written in a span of several days. A set of blog posts published in a single day raises suspicion on Google.
Content is king!
To write high quality blog posts, you should choose a topic that you are very interested in. For example, I blog about technology and gadgets because I am very interested in what's new in that field.
For the sitemap, you need to submit one to Google Webmasters Tool. If you are using Blogger, your sitemap is http://yourblog.com/atom.xml?redirect=false.
3. Use a top level domain name.If you try to apply for a Google Adsense account with a .blogspot blog, your application won't be accepted. You have to buy a top level domain name like danielgubalane.com in order to be accepted.
4. Specify the number of your house.When I applied for a Google Adsense account, I was rejected at first with the reason that has something to do with the address. My mistake was that I just put Baugo, Curva in the street address.
Since our house has no number, I just used our neighbor's house number and I got accepted.
