Recently I heard a lot of people were failed to get the adsense account where not like the old days where you just need to create a blogspot account, write certain articles and you are good to apply the accounts. If you still doing the same thing, I can guarantee that you cannot success anymore except you have a very good niche.
If you want to get some idea on how to get the adsense account then you need to have the following:
1) A decent website with at least 50 to 60 webpages before you can start to apply the adsense account
2) You need to have a term of use page
3) Privacy Policy is a must if you want to apply adsense account
4) Valid contact method or valid email address if adsense want to contact you.
If you are intend to use blog to apply adsense account, your blog should have at least 6 months old before you even can start to apply. Other than that, you blog should have a Privacy policy page.
Hope all that success in adsense account. Thanks
